Description

Portable device with digital microchip and colorless wheel projection module and colorless wheel projection method

The invention relates to a projection module, in particular to a colorless wheel projection module.

With the continuous expansion of the information and computer market, electronic products are rapidly growing under the trend of light, short, and versatile. Based on the advent of the high-tech era, telecommunications networks and the Internet are emerging industries in recent years, and the development of communication systems with mobile phone integration technology continues to provide users with a more convenient way to obtain information. As a result, communication technology has also become a new darling, and the businesses affiliated with communication devices have also flourished due to the convenience of contact needs and information. No matter the Internet, mobile communication devices, personal digital assistants have been filled with the entire living space, and the Internet and communications companies have also introduced new commercial services to help customers transfer their data or obtain to expand the market and services. In terms of electronic components, it is moving toward multi-functional development, such as light and short, multi-functional speed, and communication service providers or information providers must provide diversified, comprehensive and up-to-date information to customers. The currently used handheld communication devices include mobile phones, stock machines, and personal digital assistant systems (or personal electronic organizer devices), also known as the Personal Digital Assistant (PDA), which has become increasingly popular. It is an indispensable electronic product that is popular in the lives of ordinary people. The integration system of the above electronic devices is also generally filled with life. The so-called personal digital assistant system can have the following functions: storing personal data, business card management, time management, personal travel tracking settings, and accountkeeping, etc., but the management of these materials is gradually unable to satisfy the users for the rapid modernization of information transmission. Demand, and therefore developed electronic dictionary, real-time stock market reporting and information transmission services. The functionality of the personal digital assistant can also be embedded or integrated into a mobile phone or personal paging device for current and future developments. The conventional projection module includes a white light source, and includes a plurality of reflective lens groups and three polarizing lenses for splitting white light into red, green, and blue colors, and the optical lens group is expensive and the optical system is complicated and difficult to be reduced. The incandescent bulb source used is easy to overheat. Another type of projector is known as a digital light source projector. For example, the above projector is disclosed in U.S. Patent No. 6,733,137, issued toK. The above-described form projector uses a digital micro-mirror device and a color wheel for projection. Digital micromirror elements include millions of micromirror sections that reduce the chromatic aberration produced by changes in performance or characteristics between filters or between sources. The driving unit controls each micromirror portion of the digital micromirror device according to the corrected image signal and the rotation state of the color wheel, wherein the correction unit corrects the brightness signal of each color of the image signal, and the correction is performed by calculating the color wheel The relative intensity of the light of each filter, and the output of the photosensor when each micromirror portion of the digital micromirror element is in the off state. The color filter wheel is actuated by the motor and its volume cannot be made small, so that the projection device cannot be embedded in the hand-held device. Furthermore, conventional techniques utilize white light as a light source, thus producing high temperatures and heat during operation. This projector requires many lenses in combination with a light source and a color wheel. Since the white light passes through the high speed color wheel driven by the motor, it causes a low frequency flash frequency effect. As can be seen here, the opportunity to integrate into the projector for portability is very slim. In other words, the goal of reducing the volume of the projector is not achievable in the above-mentioned elements. Therefore, the prior art has a number of disadvantages.

In view of this, it is an object of the present invention to provide a three-monochromatic light source projection module that does not require a color filter. Therefore, the optical color separation light system is not required, the volume can be reduced, and the light-emitting element is used instead of the incandescent light bulb, so that it does not overheat.

Therefore, the data, the file, and the video game stored in the memory of the handheld communication device can be enlarged and projected to the outside through the projection display module 165. The use of the surface light sources 210R, 210G, and 210B according to the present invention provides a three-monochromatic light source such as an organic light-emitting element or a laser or a light-emitting diode, which is light and thin, so that it can be integrated into a mobile phone, a media player or a digital device. Among the cameras.

It is worth noting that the invention can be implanted in single or multiple modules, depending on the needs.

Further, another embodiment of the display unit is shown in the fourth figure, in which a cross-sectional view of a field emission display according to the present invention is shown. As shown in the fourth figure, a transparent substrate 400 is provided, and a transparent electrode 420 is formed on a transparent substrate (such as glass) 400. The transparent electrode 420 can be formed using indium tin oxide (ITO), and it can function as an emitter electrode. The stack gate 410 covers a portion of the transparent electrode 420 and is formed over the transparent substrate 400. An emitter 460 of electron emission is formed over the partially transparent electrode 420. Each stack gate 410 includes a mask layer 440 to cover a portion of the transparent electrode formed by a UV lithography mask (curtain). The mask layer 440 is preferably transparent to visible light, opaque to ultraviolet light, and may be formed by amorphous germanium. The crystal layer can be transparent when it is sufficiently thin. The stack gate 410 structure includes a first insulating layer/gate electrode/second insulating layer/focusing gate electrode, which are sequentially formed on the substrate. The gate insulating layer is preferably a thin film of germanium having a thickness of 2 μm or more, and the gate electrode may be formed of chromium having a thickness of about 0.25 μm. The gate electrode is used to extract the electron beam of the emitter. The focus gate electrode acts as a collector to collect electrons emitted by the emitter such that electrons can reach the phosphor film layer 480 disposed on the emitter 460. In the example in which the above elements are used for the display unit, the substrate may be a germanium substrate or a transparent substrate. Referring to the fourth figure, the front panel 450 is disposed upward on the stacking gate. Various visible light images are displayed on the front panel 450. The phosphor film layer 480 is attached to the bottom surface of the front panel 450 facing the stacking gate, and a direct current voltage is applied to the phosphor film layer 480 to emit color for display. When the above film has red, green and blue fluorescent substrates, the fluorescent substrate can The colored light is emitted by mixing the emitted light. In a preferred embodiment, the present invention includes three emissive displays for displaying images of red, green, and blue components (i.e., red, green, and blue images). When the electron beam excites the fluorescent substrate, it can emit red, green, and blue visible light, and is uniformly distributed on the fluorescent film layer 480. The spacers separating the front panel 450 from the stacking gate are black matrix layers, which are merely illustrative and not shown. Since the thin film display can be formed to a relatively thin thickness and consume less energy than the liquid crystal display, the present invention can provide a lighter, thinner, shorter component. The battery life can be maintained longer. Field emission displays do not require complex, power-hungry backlights and filters, which are essential for liquid crystal displays. In addition, the field emission display does not require a large-scale thin film transistor array, and therefore, the high-priced main light source and the yield of the active matrix in the liquid crystal display are eliminated. The resolution of the display can be enhanced by collimating the electrons emitted by the microtips with a focus grid or an accelerating electrode. In a preferred embodiment, the field emission display includes a carbon nanotube emitter to further reduce the size of the component. Furthermore, the display can omit the liquid crystal material. The field emission display does not require the source/drain region required for the thin film transistor of the liquid crystal display. In another embodiment, the light emitting diode source can emit monochromatic light instead of the light source of the third figure. In other words, blue, red, and green light emitting diodes can also be used as the light source. In an example, the light emitting diodes may be formed in a matrix or linear structure. It is to be noted that an element having a fluorescent substrate is shown in the fourth figure (nano carbon nanotube field emission display), and an electroluminescent panel (ELP) of the fifth figure can also be used as a light source. Similarly, the illumination source unit can be formed by three monochromatic light field emission displays (or electroluminescent panels) or a field emission display (or electroluminescent panel) that can emit three monochromatic lights. A reference to an organic electroluminescent panel display can be found in U.S. Patent No. 6,023,371, the disclosure of which is incorporated herein by reference. In addition, the laser diode can also be used as a light source. In a preferred embodiment, the color The color light source unit 1100 can include a laser 1100B and a color light conversion module 1100A disposed on the laser light path. In one example, the color-to-light conversion module 1100A can be accomplished by an efficient laser wavelength conversion technique that can generate new wavelength-converted lasers through the nonlinear nature of the material. Based on the microstructure design in the nonlinear material of ferroelectric materials, quasi-phase matching (QPM) can be used to compensate for the phase-speed matching between the interacting waves and to effectively mix. Quasi-phase matching (QPM) can be applied to laser R, G, B displays. In order to obtain effective wavelength conversion, phase matching between the interacting waves is necessary. The above objective is achieved by a birefringent phase matching technique of a nonlinear material that positions the crystal axis to a specific angle to achieve phase matching of a particular interaction wavelength. U.S. Patent No. 7,170,671, entitled "High Efficiency Wavelength Converter", discloses a method of wavelength conversion. For example, the color-light conversion module 1100A includes a waveguide having a plurality of gratings having different periodic patterns, as shown in FIG. The color light conversion module 1100A may include a waveguide element or a bulk device. The grating type can adopt a uniform grating, a parallel grating, a tandem grating, a fan-out grating, and a frequency interference grating. The laser is provided with radiation to the color-light conversion module 1100A in sequence, thereby changing the incident light to form red, green, and blue light, respectively.

In another embodiment, the light source of the fifth figure includes a lower transparent electrode 510 on the transparent substrate 500. A phosphor film or powder 520 is attached to the upper surface of the lower transparent electrode 510. In a preferred embodiment, the fluorescent substrate emits colored light. The present invention includes three elements of the present embodiment that respectively emit a red portion, a green portion, and a blue portion. Each element radiates a single color of light. Different powders emit light of different colors. The upper transparent electrode 530 is formed on the fluorescent film or powder 520. The second transparent substrate 540 is formed on the upper transparent electrode 530. A bias is applied to the electrode to inject the hole and the electron, and the combination of the electron and the hole is in accordance with the fluorescent substrate. The material (compound) excites the fluorescent substrate to emit red, green or blue visible light. The elements of this embodiment can be referenced to an electroluminescent panel. In an embodiment, the light emitting diode element can be used as a light source, and its illumination mechanism and process are simpler than conventional techniques. In a preferred embodiment, a light emitting diode source, such as a light emitting diode that emits blue, red, and green light, can be used as the three monochromatic sources.

The invention relates to a projection module applied to a portable device or a separate projector. Portable devices include, but are not limited to, mobile phones, personal digital assistants, smart phones, notebook computers, media players (MP3, MP4), digital cameras, global positioning systems (GPS), and the like.

The volume is integrated in the portable device, and the flash frequency is reduced. If there is no space consideration, there is also a color wheel. As shown in the sixth figure, the colorless wheel projector 1000 of the present embodiment includes a light source unit 1100, a digital micromirror element wafer 1200, and a projection lens group 1300.

However, it is not a feature of the present invention, and thus a detailed description thereof will be omitted. In one embodiment, the digital micromirror device wafer 1200 includes a plurality of micromirror portions (not shown) that are controlled by the drive components. The driving component generates image light to be projected onto the screen, and the tilt state of each micromirror portion is based on the switching state of the color light source. The light source unit 1100 can respectively emit red, green or blue monochromatic light, wherein the emission time of the monochromatic light is preferably less than 1/24 second, so as to facilitate visual persistence and avoid discomfort of the viewer's eyes. The color light control module 1400 is coupled to the light source unit 1100 to determine the light emission of that color. The signal fed from the alignment component and the micromirror portion The tilt state is in accordance with the alternating state of the color light source unit 1100. The color light control module 1400 is used to switch the color of light, which can be formed by an integrated circuit. The switching time of color is much faster than the rotary switching of the prior art. It reduces the time required to switch colors in the color wheel of the learned technology. The switching of the colored light units causes the light to be emitted in the order of red, blue, and green, and the switched light is output to the digital micromirror device wafer 1200. In a preferred embodiment, the color light control module 1400 causes the light source unit 1100 to sequentially emit red, blue, and green light. The alternating order of colors can be changed. The color light source unit 1100 has a plurality of color segments, and may include a white light segment if brightness is required. In a preferred embodiment, the light source unit 1100 includes a red segment followed by a green segment followed by a blue segment. To increase image brightness, each blue segment can follow a white light segment.

The organic electroluminescent element is an electroluminescent film that emits red, green, and blue light. The digital micromirror device wafer 1200 is disposed on the light incident side. The projection lens group 1300 can be composed of a plurality of lenses. Therefore, the data or files stored in the memory of the component or external device can be projected on the screen or on the wall. The user can thereby project an image, game or file onto an external screen. Electroluminescent elements are small, planar, lightweight components that allow small projection devices to be integrated into portable devices. The light source unit light source unit may be formed of three monochromatic photo field light emitting elements or one electroluminescent element that emits three monochromatic lights. In another example, the light source unit 1100 can include a light source 210W to emit white light. The light source can be formed from a film and thus can be embedded in a portable device. Similarly, as described above, the three-monochromatic light source can adopt organic light-emitting elements. Pieces, lasers, light-emitting diodes, etc.

As apparent from the above, the color filter wheel, the high temperature white light source, and some lenses such as a focus lens are not required in the present invention. Therefore, the present invention solves the heat dissipation problem, excessive volume, and flash frequency effect of the conventional projector. Furthermore, the present invention utilizes a film as a cold light source, so that there is no heat dissipation problem at a high temperature, the life of the light source is longer than that of a conventional white light source, and the noise of the motor vibration can be eliminated. The power consumption of the present invention is much lower than that of the prior art, and the light source portion can be integrated into a small portable device. The light switched by the method of the present invention is controlled by the color light control module to obtain one of red, green or blue light, and the color light is advanced to the digital micromirror device wafer 1200, and the light flow rate can be obtained by a relay lens. The calibration is measured so that the color light is efficiently reached to the digital micromirror device wafer 1200. It is known from the prior art that the color light applied to the digital micromirror device wafer 1200 is incident on each of the micromirror portions. The digital micromirror device chip 1200 receives the input signal of the signal, and according to a gray scale image signal, according to the gray corresponding to each red, green and blue light The order image signal frame is used to control the inclination of each micromirror portion. However, the correction method and the tilt state control of the micromirror portion are conventional techniques. Each of the optical images can be obtained by operating a micromirror portion of the digital micromirror device wafer 1200, and projecting a single image portion on the screen. Since the color light source unit can efficiently and quickly switch at least three colors of light to correspond to each of the grayscale image signals described above, based on the persistence phenomenon of the human eye, the color image can be seen, so that it is hardly seen. It happens when the colors are presented separately. In summary, any video playback has 24 images per second as the basic standard (this is the minimum requirement set by the TV and film industry, which is known), and is based on visual persistence requirements. Therefore, each image frame signal is at least 1/24 second. For color display requirements, at least three primary colors must be provided during the video video time. Therefore, it must switch R, G, and B at least once during the video time. In addition, the preferred time to consider which standard, such as 24 per second, 30 or more per second, the time of each video frame is 1/24 or 1/30 second, based on the three-color cycle, regardless of It is based on 24 sheets per second or 30 sheets per second. If the three colors are sequentially cycled, the monochromatic light time will usually be less than 1/72 or 1/90. Therefore, it can be inferred that the switching frequency of the color light control module is preferably at least three times faster than the frequency of the image signal. If a white light or a yellow light signal is incorporated, the switching frequency of the color light control module is preferably at least four times faster than the frequency of the image signal.
