Abstract
Active diffuser frame system (A) for a video display (D) provides ambient lighting in viewer object mode and relies on real-time video input only, with no separate lighting script required. The system uses a controllable light source, and multiple inputs to improve realism and fidelity. Video inputs include actual display light; sensing of display light; and the video display signal. The frame can include a light modulator, or a goniophotometric or goniochromatic element to change character (intensity, color) of ambient light as a function of viewing angles, or a photoluminescent emitter for new chromaticities outside the display color gamut. The frame can split light between the viewer and the frame input, and can derive an added video signal to drive selected display pixels to boost output of display light into the frame.
Description
Technical field
The present invention relates to the product of a kind of video display and ambient lighting effect thereof.Especially, the present invention relates to utilize video display light and/or display video signal to be used to control and produce the active diffuser frame system of the illuminating effect that environment distributes, this environment effect that the conversion that comprises display light space and colourity is used to produce can not be provided by conventional video display unit or printing opacity equipment that distributes as light source, signal or content resource.
Background technology
The slip-stick artist has explored for a long time and has widened by consuming video capacity, for example by enlarging screen and projected area, for 3 dimension effects modulation sound true to nature, and improvement video image, comprise wideer video colour gamut, resolution, and aspect ratio, for example have high definition (HD) Digital Television and video system and the sense that obtains.In addition, film, TV and video product also attempt to utilize audio-visual equipment, for example by using color, scene cut, visual angle, scene and area of computer aided diagrammatic representation on every side to influence spectators' impression dexterously.This point also will comprise the theatrical stage illumination.Illuminating effect for example usually is recorded simultaneously with video or performance scene, and reproduces under the help of instrument or computing machine, and this instrument or computing machine are programmed the suitable scene drama that the scheme of expectation is encoded.Illumination is in the scene, and especially the fast-changing automatic adaptation in plan or the Unrecorded scene is normally not impossible.
PHILIPS Co. (Holland) and other company disclose and have been used to change environment or ambient illumination to increase the device of typical family or the commercial video capacity of using, but it typically comprises for multiple application and utilizes independently light source, rather than video display, and the improved script of the illuminating effect of expectation or some classifications of coding.Having shown the ambient lighting that joins video display or TV is used to reduce the tired of spectators and improves the authenticity and the degree of depth of experiencing.Yet in fact be proved to be problematic in the foundation that shows near the ambient lighting exporting tightly.
This invention utilizes active framework and active diffuser frame system, uses and produces light atmosphere and luminous effect from video captured display light of video display unit own or video display signal.Video display unit can be with using any technology or platform, for example CRT (cathode-ray tube (CRT)), LCD (LCD), PDP (plasma display), FED (electroluminescent display) or other technology.For the transmission of video or visual information even can use any transmission medium, for example can find in the window of buildings.In order clearly to discuss, for the illustration purpose video display will here be used.
Sense is undoubtedly human vision a kind of function in a certain respect, the perception that it utilizes very complicated sensation and nerve fiber to produce color and luminous effect.The mankind can distinguish about 10,000,000 kinds of different colors.In people's eyes, receive or photopia power for color, exist three groups to be approximately 2,000,000 sensation bodies that are called cone, they have sharp cutting edge of a knife or a sword value is 445,535 and the light wave of 565nm, and the absorption with a large amount of crossovers distributes.These three kinds of cone types form so-called trichromatic system, are called B (blueness), G (green) and R (redness) for historical reasons; This point cutting edge of a knife or a sword value unnecessary with display in any primary colours of using, for example normally used RGB phosphor is complementary.For the low-light body, or also there is interaction in the so-called night vision body that is called rod.Human eyes typically have 100,012,000 rods, and this has influence on visual experience, especially for the low-light (level) state that for example finds in home theater.
Set up the principle that color video is based on human vision, and three looks of known human vision and channel opposing theory us have been joined and have seen desired color and the understanding that has the effect of high-fidelity for original or predetermined picture for how influencing eyes.In the color mode and space of majority, three-dimensional or coordinate are used to describe human visual experience.
Color video relies on metamersism fully, and it utilizes the generation of the reference stimuli permission color sensation of peanut, rather than the actual light of desired color and character.Like this, in the mankind's brains, utilize limited number purpose reference stimuli, the whole colour gamut that known RGB (red, green, blue) trichromatic system of for example using is come reproducing color therewith in whole world rabbit.For example, by produce the redness and the green light of number about equally in each pixel or pixel, nearly all video display shows yellow scene light.Pixel is less for the solid angle that they face toward, and eyes are deceived and the perception yellow; And be not the green or red of its actual propagation of perception.
The method that has multiple color mode and definite color comprises that known CIE (International Commission on Illumination (Commission Interationale de I ' eclairage)) color corridinate system is used to describe and the color of definite rabbit.In this is open, get rid of display or the color space is used double-colored or four colour systems system, or produce the system of multiple reference stimuli without any thing.Can use the color mode of any number in the present invention, comprise opposition color space, for example CIEL*U*V* (CIELUV) or CIE L*a*b* (CIELAB) system of using.The CIE that is built in 1931 is a mechanism for all color managements and reproduction, and its achievement is to utilize the chromaticity diagram of x, y and three coordinates of z.The zone of high-high brightness is generally used for describing color according to x and y in this three dimension system, and believes and be called 1931x, and this curve of y chromaticity diagram can be described all colours of human perception.This just and color rendering formed significant contrast, metamersism is used to deceive eyes and brain in color rendition.Use today multiple color mode or space to be used for, wherein have ISO RGB, Adobe RGB, NTSC RGB to wait reproducing color therewith by three-dimensional three primary colours or phosphor.
Yet, notice that this point is very important, it is limited promptly utilizing the scope of all possible color that the video system of these trichromatic systems shows.NTSC (standard committee of ITV international television) RGB system has the available color gamut of relative broad, but half of all colours of human perception only can be reproduced by this system.Utilize the feasible scope of conventional video system can not sufficiently reproduce multiple blueness and purple, blue-green and orange/redness.
In addition, human vision system has been endowed the ability of compensation and identification, is necessary to its understanding for any video system of design.Human color appears in the various modes of performance, and target pattern and light-emitting mode are wherein arranged.
In target pattern, the light that light stimulus is sent from light source as target reflection and perceived.Sight stimulates perceived as light source in light-emitting mode.Light-emitting mode is included in the stimulation in the complex domains, and this stimulation is brighter more than other stimulation.It does not comprise as light source, for example known stimulation of video display, and its brightness and illumination are less than or equal to the scene of eyesight or whole brightness in zone, so this stimulation shows as target pattern.
Especially, there is multiple color only to appear in the target pattern, wherein, brown, olive colour, chestnut color, grey and shallow brown yellowish pink.For example do not exist such as object, for example the traffic sign lamp of brown as the brown light emitting source.
For this reason, the direct light source of additional utilization of attempting to increase the video system of color of object can not be accomplished this point.Can not reproduce brown or hestnut color in the azarin of nearly scope and the combination of green LED (light emitting diode), this point has limited selection to a considerable extent.Only the spectral color at the brightness rainbow different with saturation degree can reproduce by the Direct observation of illuminating source.
The active diffuser frame system of this invention only depends on the video input, this video input does not have the script of ambient lighting coding needs or additional communication, and active diffuser frame system can utilize the multiple input of video to improve the authenticity and the fidelity of video image.
The existing systems that view is incorporated into space outerpace with light usually need one independently information channel be used for system's operation, required independently amusement control signal in 6166496 kinds of disclosed illumination entertainment systems of United States Patent (USP) of Lys etc. for example, perhaps required computer code or the computer applied algorithm of disclosed running environment illumination in the United States Patent (USP) 2003/0057884 of Dowling etc.In any analog waveform space, there are not the space environment illumination code or the instruction of virtual video broadcast system, vertical blanking interval in the NTSC broadcast system for example, and do not have virtual digital image system (for example DVD form, MPEG4 etc.) or in any subcode, do not have space environment illumination code, for example DVD subcode or synthetic digital video auxiliary space.
Another shortcoming of multiple existing ambient lighting system be the light source that uses can not be in target pattern display video information, therefore can not produce the huge expansion of human color space by them.
Another shortcoming is roughly to be positioned near the current description of the ambient lighting of video conveyer, or display utilizes known human visual system's characteristic to cause the chance that loses tragicly, it is physically normally unrealistic, outdated near a possible reason of video display unit to utilize active light source to avoid ambient lighting to realize, and is unintelligible.
Usually, driving them does not match basically with the conventional lighting sources of generation surround lighting and the quality and the nuance of method and video display.In other cases, the source of depending on the classification in virtual image space is used for that another video display of creation environment light product-for example the United States Patent (USP) 6611297 of Akashi is disclosed basically.Although wherein the framework around the suggestion display can be used for pseudo-light emission or target pattern, the illumination control data that needs independent source, and do not provide instruction so that gratifying and real output to be provided, color space that this output is available and display itself coupling-or do not need to create the virtual image space that record illumination control data independently embodies or do not need to add up to the video display that appends away from display-utilize cheap system, this system.
Therefore it is preferred must not bearing and create the virtual image space, and second display as the illumination framework is created in this space basically, and does not need the illumination control data that independently gets, and only depends on that video display unit can first-hand data.Surpass conventional light source can with colour gamut and surpass typical trichromatic vision frequently the colour gamut that may reproduce of display system also be preferred.Also wish to utilize the characteristic of human eyes, for example by utilizing active frame system modulation or changing the color that sends to video user, the change of the relative brightness of the different color of the function of work usefulness light grade, this frame system has been used for other characteristic of compensating effect, sensitivity and the human vision of advantage, they are preferably used in the framework of display, or close related surround lighting with video display is provided.Also wish to make this system to adapt with existing broadcasting and NTSC, SECAM, PAL and MPEG4 product standard backward.
The mode of direction and propagates light of can not catching by the present invention described here, change around the existing framework of video screen is come driving functions.Than multiple existing design, the present invention does not relate to the sidelight of display interior, for example traditional CRT.The light of display surface for example, was compared with the US patent 2837734 surround lighting structures of R.M.Bowie before the present invention only caught and comes from, and the CRT sidelight that comes from the light belt of clear glass 22 in this patent is caught by planar transparent parts 30.

The outward appearance of active diffuser frame A and display D is illustrated among Figure 12, and the front schematic view that wherein is similar to Fig. 7 illustrates the active diffuser frame system of angle measurement luminosity of Figure 11.As directed display D sends original display imaging 1.Under the situation of the external frame AF that has distribution with fan diffuser core or feature, surround lighting M adopts the form of the non-imaging 3 of as directed framework, and adopts the form of the non-imaging angle measurement of the framework luminosity light 4 that sends from angle measurement luminosity element AN shown in the sectional view of Figure 10.
With reference now to Figure 13 and 14,, the common schematic cross-section according to the top of the active diffuser frame system of non-barrier of the present invention is shown, what its utilization put on video display unit has source video signal to control the light source LS of active diffuser frame A inside.In Figure 13, schematically illustrated video display signal RF conduct obtains from display D in any known mode, comprise and utilize the sensor that offers consumer's adapter or the method picked up signal that some are complete, signal obtains from display D is inner in the method, comprise known induction sensation or large-scale signal wire or conveyer line, it comprises any coaxial line, optical fiber or provides video information and relevant arbitrarily data arrive any other signal source and bit stream of display D.Infrared, bluetooth from display D to processor CPU or width modulation communication shown in this can comprise.Known compression technique can be used in this communication.The data that tap into video display signal RF can comprise simulating signal, for example NTSC, PAL or SECAM waveform, or form by numerical information, comprise information source coding and any subcode or auxiliary data and metadata.Processor CPU utilizes video and television engineering field known principle to use video display signal RF then, be depicted as here with shown in active diffuser frame A combine or be fixed on the active diffuser frame A.Replacedly, processor CPU can join among the display D, maybe can be independent of active diffuser frame A or display D and exist.As previously mentioned, by the external frame AF that photoconduction LG injects to distribution, produce the non-imaging 3 of framework from the output light of light source LS.
In Figure 14, another embodiment is shown, wherein for the active framework input of the video display signal RF that sends to video display unit, active diffuser frame system utilizes long-range induction, for example electromagnetic coupler EC1 and EC2.In this embodiment, video display signal RF, its part and the signal that comes from video display signal RF directly and are indirectly used, utilize the known technology of electronics and electric field, drive electromagnetic coupler EC1 comes from video display signal RF with coding expected information by this way.If desired, exist some to simplify the Video signal processing method, the subclass of pixel in the sampling scope only for example, homogenizing technology maybe may allow the data payload of any required driver (not shown) to reduce to supply with other the compression sampling technique of electromagnetic coupler EC1.In a similar fashion, the signal that processor CPU can utilize electromagnetic coupler EC2 inductance or electromagnetism to receive, this electromagnetic coupler EC2 and electromagnetic coupler EC1 carry out electromagnetic communication.This allows active diffuser frame A, especially has portability for flat-panel monitor (non-CRT).Electromagnetic coupler EC2 takes the form of antenna, maybe can be disclosed optical devices, for example those this areas usually available and known, this area utilizes IRED (infrared light light emitting diode) or similar transmitter codes and transmit signal message.Can use the configuration of any number.For example, electromagnetic coupler EC1 can be the part of display D, or is fixed to display D or is associated with display D, and electromagnetic coupler EC2 is the part of active diffuser frame A, thereby portability and interchangeability are provided.
With reference now to Figure 15,, illustrate according to the active diffuser frame A that is similar to another embodiment shown in Figure 13, the output light that wherein comes from light source LS is modulated by framework photomodulator AM.Just as can be seen, framework photomodulator AM is the part of the external frame AF of distribution now, and between the external frame surfaces A S of light source LS and distribution, thereby the characteristic of the light that light source LS produces, for example brightness, colourity and saturation degree can be changed before environment distributes, become the surround lighting 3M that is called modulation here, as directed.This allows the luminous effect of any number, and it is carried out by active framework input, and for example the content that obtains of video display signal RF is determined.Framework photomodulator AM can comprise change to transmit or turnout as the independent device of the function of time or position, or one group of device, the planar array that occurs among for example this equipment such as the LCD (LCD), or allow light by himself, and self be active light, the composite set of FED (electroluminescent display) or PDP (plasma display panel) for example.
As another example, refer now to Figure 16, the similar view of Figure 15 is shown, but for another embodiment that utilizes part barrier structure, wherein also allow some to show that output light K enter photoconduction LG, with the same among the embodiment shown in Figure 11.In this embodiment, show that the output light of output light K and light source LS all passes through photoconduction LG, and outwards arrive environment space by the external frame AF that distributes.Processor CPU for the sake of clarity is not shown here.
Utilize framework photomodulator AM, scene can be projected onto on the external frame AF of distribution, and this framework replenishes the content of display D with satisfactory way.Produce origin beginning from the active framework output that video display unit D obtains of the control signal of this content, must not come from script or subcode or the special data space of video display signal RF.
The light that is changed direction by the external frame AF that distributes can be non-imaging and mixed, allows three primary colors or other color combinations.This allows all mixing as shown in figure 24, thereby the two kinds of color A and the B that come from two kinds of different scene areas on the display can form not shown chrominance C on original image, but for eyes are pleasant, just as what obtain from original image content.Therefore, can be distinct though offer the light of the external frame AF of distribution, for example independent redness and green area, the surround lighting 3M that active diffuser frame produces can be yellow, and interesting stagewise is provided.When comprising fan diffuser, especially improved the external frame AF that distributes this point.This point can for example produce target pattern color, for example brown from being difficult to produce the light source of brown in the led array.
With reference now to Figure 17 and 18,, provided respectively among the embodiment shown in Figure 15 and 16 for the basic principle schematic of luminous flux is described.In Figure 17, light source (illustrates, light source) and among Figure 18, light source and some display lights (demonstration is shown) produce the RGB light components, or as framework light alleged in the accessory claim, and the photoconduction LG shown in this light all passes through in two kinds of situations, and the framework photomodulator AM shown in upwards arriving, it is illustrated movable part green light (G), sees through shown in the arrow that weakens of green glow as expression.The external frame AF of this light modulated by distributing, and in this illustrative embodiment, it mixes with formation and propagates into pinkish red coloured light (magenta is shown) in the environment space.Utilization is collected from one or more active frameworks inputs, and control framework photomodulator AM is as the known method of the action of display D, and this colourity selects to be modulated to the function of the position on the frame outer surface AS of distribution, and the function of time.
Figure 19 illustrates and similar another embodiment of the part mode shown in Figure 16, but the additional vision signal that offers video display unit of wherein active diffuser frame system also comprises illustrative angle measurement luminosity element shown in Figure 11 to produce the video display light of modulating.This embodiment of the present invention allows processor CPU (for the sake of clarity not shown) to utilize to show the passive detection of output light K or video display signal RF to produce the vision signal (following discussion) of reference area, this vision signal is provided for video display unit D to drive or to increase selected output pixel in (or then compressing brightness if desired) video display unit, and this video display unit is arranged in reference area FA shown in Figure 1 display light (K+) with the modulation shown in the generation.For example, this point allows the increase of light yield because exist now about two kinds of original display D new light sources: the light source LS of active diffuser frame A and come from shown in the display light K+ of modulation of display D.As previously mentioned, the display light K+ that modulated passes through photoconduction LG with the output light that comes from light source LS, and upwards passes through the external frame AF of framework photomodulator AM and distribution.The part of this light is by angle measurement luminosity element AN in this illustrative example, the non-imaging angle measurement of the framework luminosity light 4M shown in producing now, its can change as shown in the characteristic of visual angle function.
In another embodiment of the present invention, photoconduction LG allows original display light to pass to spectators from reference area FA simultaneously, and by using active diffuser frame system also to allow to extract and utilize display light.
With reference now to Figure 20,, utilize the cross section close up view on the top of display D that this embodiment is shown, it illustrates the reference area (for the sake of clarity not tagging) that is equipped with active diffuser frame system.The form of the rectangular prism shown in the photoconduction LG here takes, and the feasible critical surfaces that 100% internal reflection takes place thereon that provides so is provided.
Especially, shown in the external frame AF of photoconduction LG and/or distribution forms with allow critical surfaces CS be present in whole internal reflection critical angle place or near.The front bevel of external frame AF of distribution on right side that is illustrated in figure is to form critical surfaces CS, and the normal vector of this critical surfaces CS approximately departs from 45 degree from the common output light outward direction D (K) that sees easily.Because the critical angle of the internal reflection of most of particle typically is approximately 42 degree, this provides a kind of chance that enters into photoconduction LG that light is separated, because selected geometric configuration, as directed, almost half light that enters will be above critical angle to become internal reflection output light KX, when the framework photomodulator AM that installs at the top shown in it passes through, became framework modulate ambient light 3M-afterwards and light enter photoconduction LG second half be not changed direction, and will become the output light KT that is transmitted forward, and become framework imaging 2 as shown.Therefore, spectators will receive or be identified in the primitive character of the original displayed image among the reference area FA, yet, distributing for environment simultaneously, light can be used to from the upwards emission of external frame AF that distributes.Therefore see original display image under the brightness that bright or transparent active diffuser frame A allows reducing in whole viewing area, this point does not pay particular attention to owing to human visual system's compensation characteristic itself.For the sake of clarity, for the output light KT that transmits the little difference in directly exported place is not shown.
Therefore the internal reflection of break-in output light KX can be used as the input of active diffuser frame system, may substitute display light sensor DS with framework photomodulator AM, or both combination in any, further to provide information to active diffuser frame A and any relevant processor CPU (not shown).
Also show another feature, promptly use front surface reflector or reflecting surface T with the reflected light of reflection photoconduction LG inside to become environment separation light (illustrate, separate).This luminous energy illuminates the rear wall shown in Fig. 8.
As the alternative embodiment of the Amici prism embodiment shown in Figure 20, Figure 21 utilizes local reflex surface T2 to substitute the internal reflection at critical surfaces CS place.As previously mentioned, part light, i.e. internal reflection output light KX upwards reflects the input as active diffuser frame A, the framework photomodulator AM shown in for example passing through, and/or interchangeable, display light sensor DS (not shown).Other light is transmitted the output light KT that is transmitted to become as previously mentioned.The external frame AF that joins the photoconduction of a physical block assembly and distribution now major part as shown is a hollow, and has the light-path shown in the front among Figure 20.It can be preferred utilizing partial reflection surface T2, because when the refraction internal reflection that has shown in Figure 20, does not reflect displacement effect crossing on the image that critical surfaces CS will discern; Yet, utilize the local reflex surface to have the shortcoming of introducing the part light loss at reflecting surface, and absolute during 100% the internal reflection at the critical surfaces CS place of Figure 20.Noted earlier as Figure 20, front surface reflector T is used to strengthen the rear side of crossing the surround lighting shown in the display D top and separates.Alternative embodiment as continuous local reflex surface T2, on little physics scale, can use and select reverberator and partial reflector, it reflects individually and changes part and shows direction of light with the separation that becomes, and other light is selected between the reverberator to increase framework imaging 2 by these.
Usually, instruction given here also can be applicable to many aspects.Geometric configuration for the Amici prism of the external frame AF of photoconduction LG and/or distribution can comprise the plane that whole framework is independent, interchangeable, Amici prism can comprise four planes, and each is corresponding to the every side (referring to Fig. 1) that shows the benchmark border, i.e. top, bottom, left side and right side.Interchangeable, may have regional prism or little prism, even the prism of Pixel Dimensions is to obtain to go up on a small scale identical influence.
The external frame AF that distributes can also comprise one or more photoconductive tube (not shown), for further output or distribution environments light certain location in the environment space, or for unshowned specific purpose.For example, photoconductive tube can be fixed on the rear side of the external frame AF of distribution in Figure 20 or 21, the position that the separated light shown in being adjacent to is exported backward.The surround lighting M that produces from these photoconductive tubes is drawn in other photo structure for other local use by optics, for example for special effect optical distributor (not shown) or top board is installed and is splashed down the floor of unit (not shown).For also can be used as transmission light, the environment distribution light pipes is used for amplifying.
One of obtainable function of the present invention is by obtaining from original displayed image light 1, rather than the product of the active framework of in esse colourity.This point is carried out not relying under situation heat or active light source, LED for example, even when primary colours are combined, its colourity as discussed previously is difficult to Be Controlled.For example, original display imaging 1 can be by color conversion or color modulation.This point allows to utilize the characteristic of human eyes and vision system.It should be noted that the luminosity function that provides the human visual system of detection sensitivity for different vision wavelength changes as the function of intensity level.
For example, noctovision or the night vision that depends on rod tended to more responsive for blue light or green light.Utilize the photopic vision of retinal cones more to be applicable to the wavelength that detects than long, for example red and yellow.In the home theater environment of dark, change in environment space by modulation or change the color that sends video user to being cancelled as these of the relative rediance of the different colours of the function of intensity level.This point is utilized framework photomodulator AM, or adopt the color subtraction step to be implemented by the instruction that utilizes the another embodiment of the present invention shown in Figure 22, Figure 22 illustrates the top of Figure 21, but is equipped with the parts of increase, i.e. the photoluminescence device of further light modulated before environment discharges.When the output of the internal reflection shown in the Figure 21 of front light KX upwards forms in Figure 22, it is as previously mentioned by framework photomodulator AM, further by photoluminescence device PE, this photoluminescence device PE is as directed to be applied to or to be fixed to, or combines with framework photomodulator AM then.As another embodiment, with reference now to Figure 23, be similar to the embodiment shown in Figure 15 on another the embodiment function of the present invention, comprise the photoluminescence device PE between the frame outer surface AS that places framework photomodulator AM and distribution in addition.In this case, the output light that comes from light source LS is used for environment release by feasible being propagated into by the external frame AF that distributes of framework photomodulator AM then by photoconduction LG in the environment space.Interchangeable, photoluminescence device PE can combine with the external frame AF that distributes.
Photoluminescence device PE is by absorbing or experience is carried out the transformation of color from the light of light source LS input or from the excitation of the light K (for example KX) that shows output, and then the emission light of the wavelength of expectation more.By the photoluminescence device, for example this excitation of fluorescent pigment and again emission can allow to be provided in raw video image or the light source non-existent new color originally, perhaps also may be not in the scope of intrinsic color of operation display D itself or colour gamut.
Figure 24 illustrates the basic principle schematic for the explanation luminous flux of this process of embodiment that provides among Figure 23 for example.The rgb light that comes from light source (display or light source are shown) passes through for example TFT LCD display of framework photomodulator AM, arrive then on the photoluminescence device PE, wherein the excitation of different wavelength range or absorption produce orange O by other mixing (for example the frame outer surface AS place of distribution), it provides a kind of script non-existent new color (orange increase is shown) in display or light source.
The generation of new color can provide new and interesting visual effect.This illustrative example can be the product of orange-colored light, for example is called the orange of searcher, can use known fluorescent pigment (referring to ref[2]) for it.This example that provides relates to fluorescent color, and it is opposite with common phenomenon of fluorescence and relevant phenomenon, additionally is devoted to outside the orange specific example of searcher for this figure of this point.In other words, any photoluminescent compounds, material or material can be used for photoluminescence device PE, as long as it has corresponding to the light source of active diffuser frame A inside or the activation or the excitation energy of the energy.
Utilize fluorescent orange or other fluorescent dye kind can be used for the low-light (level) state especially, wherein for long wavelength's light, increase red and orange-colored light can be offset the scotopic sensitivity that reduces.
Fluorescent dye can comprise dyeing known in the dyestuff kind, for example perylene, naphthalimide, cumarin, thioxanthene, anthraquinone, thioindigo and all dyestuff kinds, for example dyestuff of making by the colored company of the Day-Glo of Cleveland, Ohio, Usa.Available color comprises A Paqi yellow, Tigris yellow, prairie yellow, Pocono yellow, the Moho gram is yellow, the potomac is yellow, marigold is orange, the Ottawa is red, Volga is red, orange pink colour, Colombia's blueness.These dyestuff kinds can utilize known program to join resin, for example among PS, PET and the ABS.
Fluorescent dye and material have improved visual effect, and be bright more a lot of than the non-fluorescent material of identical colourity because they are designed to.The problem of so-called term of life that is used for traditional orange pigment of common iridescent has obtained solution in recent two decades, because technical progress has caused the development of durable fluorescent pigment, this fluorescent pigment can keep their strikingly color 7-10 in the sun when exposing.Therefore these pigment almost do not destroy in the environment of the minimum home theater of UV ray inlet.
Interchangeable, can utilize the fluorescence photopigment, they are by absorbing short wavelength light, and launch for example red or orange light as long wave again and work.The inorganic pigment of technical progress easily can use and utilize visible light through irriate now, for example blue light and purple light, and wavelength is a 400-440nm light.
The height fluorescent material produces monochromatic light as known fluorescence, the psychological physic perception of fluorescent color phenomenon, and this monochromatic light sends and seems factitious brightness.
When this phenomenon like never before keeps in large quantities, can obtain brightness (with respect to white) quantitatively by the MacAdam modeling as the theoretical maximum of colourity function, and known in the color science field as the MacAdam restriction.Advised that fluorescence can (x y) describes, and wherein Y is the relative reflection coefficient or the lip-deep reflection coefficient of fluorescent color excitation, and (x y) is chromaticity coordinate (x, MacAdam restriction y) of fluorescent color excitation to YMacAdam by Y/YMacAdam.
The colored transition process that Figure 25 illustrates Figure 24 according to the present invention with for available colourity recently, the comparison between the colored transition process of the video color product of the routine that produces by display or conventional light source.As scheme shown in the left side, that utilizes that the raw video image of primary colours R, G and B or light source produce that display or light source itself can not produce is new orange, as shown in figure 24.Light outside this colour gamut is depicted as surround lighting M+.Compare with this point with by the light that utilizes display or light source itself to produce, the product of the same color of nearest colourity, the example of property as an illustration wherein, the light that comprises the green light (being depicted as g) of the red light (being depicted as R) of high brightness and low-light level is filtered to produce orange (illustrating by framework photomodulator AM with subtracting each other, orange), this orange-colored light is still within the colour gamut of display relevant with active diffuser frame A or light source generation itself.This figure diagram illustrates demonstration and utilizes the photoluminescence illuminator according to the present invention, and the light that active diffuser frame produces can exceed the MacAdam restriction of this colourity.
Figure 26 shows the principle schematic that forms this process, can use fluorescence with the color outside the colour gamut that produces video display generation itself by this process active diffuser frame of the present invention.The rgb light that comes from display color gamut (RGB) is allowed to the fluorescent material within the exciting light photoluminescence device PE, and the external frame AF that allows to distribute produces the color outside the colour gamut that the proper operation of display D or light source LS can use.Be illustrated among Figure 26 to this point diagrammatic, wherein fluorescence causes the product outside the colour gamut color.
For illustration purpose, Figure 27 illustrates for the operable fluorescent material of embodiment shown in Figure 22,23,28 and 30 (searcher orange), the existing frequency spectrum profile of activation, reflection, fluorescence and total output (come from ref[2], the 365th page).Photoluminescence device PE in this example is by the shorter light wave excitation that is depicted as E.Common reflection process shown in the R is replenished by the distribution of the fluorescence emission spectrum shown in the F, and addition obtains total emission of the height output shown in the HO, and it can be positioned at outside the colour gamut of display D itself.
Figure 28 illustrates the angled section figure of the external frame AF of the simple Amici prism distribution of part, and AF and photoconduction LG combine.Come from light source, for example the part light of light source LS (not shown) and demonstration output light K (not shown) is changed feasible framework imaging 2, for example blue light shown in of not becoming of direction.Alternative, this light is by internal reflection and upwards be sent to framework photomodulator AM in the drawings, and the liner of the photoluminescence device PE shown in the external frame AF top of passing through subsequently to distribute.This point changes the orange-colored light outside the colour gamut into will export light (for example blue light) with the identical mode shown in the spectrum distribution of Figure 27, as shown in the non-imaging 3 of framework appear in the environment space.
This process can easily produce the surround lighting outside the colour gamut of display D itself.With reference now to Figure 29,, the two kinds of possible environmental colors or the chromaticity coordinate that are depicted as M+ can find on standard C IE x-y colourity chart or colour map.This ground illustrates all the known colors as the high-high brightness of the function of chromaticity coordinate x and y, for reference illustrates light and the luminous white point of CIE standard with nano wave length.Illustrate easily the environment color M+PAL/SECAM, the NTSC of colourity shown in being positioned at and the obtainable colour gamut of Adobe RGB tristimulus product standard outside.
