Network 3 can mode of operation be coupled to various devices.The example that can be coupled to the device of network 3 comprises computing machine (for example laptop computer 4), PDA(Personal Digital Assistant) 5 (it can comprise wireless handheld device, for example Blackberry, Palm Pilot, Pocket PC and similar device), and mobile phone 6 (for example the mobile phone that is started by Web, Smartphone, and similar device).Also can use multiple other devices, for example Desktop PC, set-top box, digital media player, hand-held PC, GPS (GPS) guider, Vehicular display device or other displays static and that move.For ease of discussing, in this article all these devices are referred to as client apparatus 7.
Fig. 2 shows that one comprises the bistable display element embodiment of an interfere type MEMS display element.In these devices, pixel is in bright state or dark state.Under bright (" opening (on) " or " opening (open) ") state, display element reflexes to the user with most of incident visible light.Be in dark (" closing (off) " or " closing (closed) ") state following time, display element reflects the incident visible light to the user hardly.Decide on different embodiment, can put upside down the light reflectance properties that " on " reaches " off " state.The MEMS pixel can be configured to mainly reflect under selected color, also can realize colored the demonstration except that black and white.
Fig. 2 is an isometric drawing, and it shows two adjacent pixels in a series of pixels of a Visual Display array, and wherein each pixel comprises a MEMS interferometric modulator.In certain embodiments, an interferometric modulator array of display comprises a row/column array that is made of these interferometric modulators.Each interferometric modulator comprises a pair of reflection horizon, and this is positioned to each other to have a variable-sized optical resonance cavity at a distance of a variable and controlled distance at least to form one to the reflection horizon.In one embodiment, one of them reflection horizon can be moved between the two positions.Be referred to herein as on the primary importance of release conditions, the local reflex layer that the position of this displaceable layers distance one is fixed is far away relatively.On the second place, the position of this displaceable layers is more closely near this local reflex layer.Decide position according to removable reflection horizon, from the incident light of this two layers reflection can with mutually long or mutually the mode of disappearing interfere, thereby form the mass reflex or the non-reflective state of each pixel.
The pixel array portion that shows in Fig. 2 comprises two adjacent interferometric modulator 12a and 12b.In the interferometric modulator 12a in left side, demonstration one movably high reflection layer 14a is in an off-position, and this off-position is apart from fixing local reflex layer 16a one preset distance.In the interferometric modulator 12b on right side, demonstration one movably high reflection layer 14b is in an excited target position, and this excited target position is near fixing local reflex layer 16b.
Local reflex layer 16a, the 16b conduction, local transparent and fixing, and can make by the layer that for example on a transparent substrates 20, deposits one or more respectively do for oneself chromium and tin indium oxides. described each layer is patterned into parallel band, and can form the column electrode in the display device, as further specifying hereinafter. high reflection layer 14a, 14b can form by one or more depositing metal layers that is deposited on pillar 18 tops (with column electrode, local reflex layer 16a, the 16b quadrature) and one be deposited on the series of parallel band that the middle expendable material between the pillar 18 constitutes. after expendable material is etched, these deformable metal levels separate with the air gap 19 of the metal level of fixing by a regulation. and these deformable layer can use one to have high conductivity and reflexive material (for example aluminium), and those bands can form the row electrode in the display device.
When not applying voltage, air gap 19 remains between a layer 14a, the 16a, and deformable layer is in the mechanical relaxed state shown in interferometric modulator pixel 12a among Fig. 2.Yet after a selected row and column applies potential difference (PD), the capacitor that forms at the respective pixel place of described row and column electrode intersection is recharged, and electrostatic force pulls to these electrodes together.If voltage is enough high, then displaceable layers generation deformation, and be forced on the fixed bed (can on fixed bed, deposit a dielectric material (not shown in this Figure), preventing short circuit, and the control separation distance), shown in the interferometric modulator 12b on right side among Fig. 2.Regardless of the potential difference (PD) polarity that is applied, the behavior is all identical.This shows that the may command reflection is similar in many aspects to row/row excitation used in traditional LCD and other display techniques to the row/row excitation of non-reflection interference type modulator state.
Fig. 3 to Fig. 5 shows that one uses the example process and the system of an interferometric modulator array in a display application.Yet this process and system also can be applicable to other displays, for example plasma scope, EL, OLED, STN LCD and TFT LCD display.
Current, existing flat-panel monitor controller and driver are to be designed to almost only together use with the display that need refresh always.Therefore, if in one second, do not refresh many times, will disappear part second of shown image on for example plasma scope, EL, OLED, STN LCD and TFT LCD panel then.Yet, because the interferometric modulator of type mentioned above can make its state keep a longer time cycle under situation about not refreshing, wherein the state of interferometric modulator can remain in one of two states under situation about not refreshing, thereby can will use the display of interferometric modulator to be called bi-stable display.In one embodiment, by applying the state that a bias voltage (be called sometimes and latch voltage) keeps pixel element to the one or more interferometric modulators that constitute pixel element.
Generally speaking, a display device need use one or more controllers and driving circuit correctly to control this display device usually.Driving circuit for example is used to drive the driving circuit of LCD, can directly be bonded to display panel self and along the location, edge of display panel self.Perhaps, driving circuit can be installed on display panel (in its edge) is connected on the flexible circuit element of remainder of an electronic system.In both cases, driver all is usually located at the interface of display panel and described electronic system remainder.
Fig. 3 A is a system block diagrams, and it shows that one can comprise some embodiment of the electronic installation of various aspects.In this exemplary embodiment, described electronic installation comprises a processor 21, and it can be any general purpose single-chip or multicore sheet microprocessor, for example ARM,

Figure G2005101034468D00103
Or any special microprocessor, for example digital signal processor, microcontroller or programmable gate array.According to convention in the industry, processor 21 can be configured to carry out one or more software modules.Except that carrying out an operating system, also this processor can be configured to carry out one or more software applications, comprise web browser, telephony application, e-mail program or any other software application.
Fig. 3 A shows the embodiment of an electronic installation, described electronic installation comprises that one is connected to the network interface 27 of a processor 21, and according to some embodiment, described network interface can be connected to array driver 22. network interfaces 27 and comprise suitable hardware and software, so that described device can carry out reciprocation by a network and another device (server 2 for example shown in Figure 1). processor 21 is connected to driving governor 29, driving governor 29 is connected to array driver 22 and frame buffer 28. again in certain embodiments, yet processor 21 also is connected to array driver 22. array drivers 22 and is connected to and drives the configuration that each assembly shown in array of display 30. Fig. 3 A shows an interferometric modulator display., this configuration also can be used with lcd controller and driver in LCD. as shown in Figure 3A, although driving governor 29 by a bus 36 in parallel be connected to processor 21. 1 driving governors 29 (a for example lcd controller) usually as one independently integrated circuit (IC) be associated with system processor 21, but these controllers can make up by many kinds of modes. it can be used as hardware and is embedded in the processor 21, be embedded in the processor 21 as software, or it is fully-integrated with example, in hardware and array driver 22. in one embodiment, driving governor 29 receives the display message that is produced by processor 21, with this information suitably reformatting so that the information of high-speed transfer after to array of display 30, will formaing then is sent to array driver 22.
The self-driven controllers 29 of array driver 22 receive the information after the format and video data are reformated into one group of parallel waveform, and the parallel waveform per second of this group many times is applied to from hundreds of of the x-y pel array of display, thousands of lead-in wires sometimes.Existing flat-panel monitor controller and driver (for example above just described) are to be designed to almost only together use with the display that need refresh always.Because bi-stable display (for example interferometric modulator array) does not need thisly to refresh right, thereby can utilize bi-stable display to realize the feature of cpable of lowering power demand.Yet,, may not make the advantage optimization of bi-stable display if use the controller and the driver that together use with existing display to operate bi-stable display.Therefore, expectation has controller and the drive system and the method for the improvement that is used for bi-stable display.For the high speed bi-stable display, interferometric modulator for example mentioned above, the preferable execution of the controller of these improvement and driver is hanged down refresh rate pattern, video rate refresh mode and is used to realize the unique pattern of the unique function of bistable modulator.According to method and system as herein described, bi-stable display can be configured to reduce in every way power demand.
In the embodiment shown in Fig. 3 A, array driver 22 is by data link 31 self processors 21 receiving video datas of walking around driving governor 29.Data link 31 can comprise serial peripheral interface (" SPI "), I2C bus, parallel bus or any other interface that can have.In the embodiment shown in Fig. 3 A, processor 21 provides instruction to array driver 22, so that array driver 22 can be optimized the power needs of array of display 30 (for example interferometric modulator display).In one embodiment, for example intending being used for can be by the packet header message identification and by data link 31 transmission by the video data of the part of the display of server 2 defineds.In addition, processor 21 can be routed to array driver 22 along data link 31 with primitive such as for example graphic primitives.These graphic primitives can for example be used to draw the primitive of shape and text corresponding to instruction.Still referring to Fig. 3 A, in one embodiment, video data can provide to array driver 22 by data link 33 automatic network interfaces 27.In one embodiment, the control information that network interface 27 is analyzed from server 2 transmission, and whether decision should be routed to processor 21 or array driver 22 with the video of input.
In one embodiment, the video data that provides by data link 33 is not stored in the frame buffer 28 as common situation in many examples.Should also be clear that in certain embodiments, also can use one second driving governor (not shown) to provide video data as array driver 22.Data link 33 can comprise SPI, I2C bus or any other interface that can have.Array driver 22 also can comprise address decoder, row and row driver and the similar device of display.Network interface 27 also can be at least in part in response to provide to the video data of network interface 27 embedded instruction and video data is directly provided to array driver 22.The person of ordinary skill in the field should be appreciated that, can use arbitrated logic to control the visit of being undertaken by network interface 27 and processor 21, to prevent data collision occurring at array driver 22 places.In one embodiment, one driver in operation on the processor 21 passed through during the time interval of not used by processor 21 usually, for example during being generally used for the time interval that vertical blanking postpones and/or horizontal blanking postpones, allow the data transmission of automatic network interface 27, control the timing of described data transmission to array driver 22.
Preferably; this design allows server 2 to walk around processor 21 and driving governor 29; and directly the part of array of display 30 is carried out addressing. for example; in the embodiment shown; this allows server 2 directly addressing to be carried out in the array of display zone of the pre-regulation of one in the array of display 30. in one embodiment; the data volume that transmits between network interface 27 and array driver 22 is relatively low; thereby for example use (I2C) bus or serial peripheral interface (SPI) between integrated circuit however universal serial bus such as bus transmit.; should also be clear that; when utilizing the display of other types, also will use other circuit usually. the video data that provides by data link 33 can advantageously show under the situation of no frame buffer 28 and the intervention that has little or no from processor 21.
Fig. 3 A shows that also one is coupled to the configuration of the processor 21 of a driving governor 29 (for example interferometric modulator controller).Driving governor 29 is coupled to array driver 22, and array driver is connected to array of display 30 again.In this embodiment, driving governor 29 realizes the optimization of array of display 30 and provides information to array driver 22, and need not to have independent being connected between array driver 22 and processor 21.In certain embodiments, processor 21 can be configured to communicate with a driving governor 29, and driving governor 29 can comprise that one is used for temporarily storing the frame buffer 28 of one or more video data frames.

Because as most of flat-panel monitors, bi-stable display is to consume its most of power between frame updating period, thereby hope can be controlled frequency that bi-stable display is upgraded so that saving power.For example, if the variation between the consecutive frame of a video flowing is very little, then can be more update displayed array continually not, and can or can not undermine image quality hardly.As an example, in the desk-top application of typical PC, the image quality that on interferometric modulator display, shows will be can be because of refresh rate reduces variation, this is because interferometric modulator display is not easy to cause flicker because of reducing refresh rate as other displays of great majority.Therefore, in service in some application, the PC display system can reduce for example refresh rate of bistable display element such as interferometric modulator, and very little to the influence of the output of display.
Figure 10 shows an embodiment of an interferometric modulator display 200 with the plan view In the view of the observer, and in the present embodiment, this interferometric modulator display 200 has been divided into one first district 202, one second district 204 and one the 3rd district 206.In these embodiments, the character of shown image in the apparent respective area 202,204,206 and deciding, with regard to image shown in being updated in different district 202,204,206, can be a kind of independent, different mode is treated the not same district in the interferometric modulator display 200, for example first district 202, second district 204 and the 3rd district 206.
For example, in one embodiment, first hurdle 202 can show that one has the tool bar of a plurality of icons, and these icons are corresponding to comprising the different serviceability that the device of interferometric modulator display 200 provides by one.After the explanation of considering each embodiment, should be appreciated that, interferometric modulator display 200 can be incorporated in the various electronic installations, and these electronic installations comprise but are not limited to cellular phone, PDA(Personal Digital Assistant), text citation device, counter, portable type measuring or medical apparatus, video player, personal computer and similar device.Therefore, in one embodiment, the image that has a tool bar of a plurality of icons corresponding to one can be described by first district 202, the painted or highlighting of a special icon changed in first district 202 when selecting corresponding function, described a plurality of icons can keep a constant configuration and a position with respect to interferometric modulator display 200 during use.Therefore, shown image will need not upgrade continually relatively or do not upgrade in some application-specific usually in first district 202 of interferometric modulator display 200.
One second district 204 can have corresponding to a shown image in the interferometric modulator display 200 and obviously is different from the zone that presents the upgrade requirement of image in first district 202.For example, second district 204 can be corresponding to a series of video images of Gao Gengxin speed (for example corresponding to about 15Hz of a video flowing renewal rate) more that show that presented on interferometric modulator display 200.Therefore, more new demand to institute's image represented in first district 202 can be not frequent aperiodicity character, if for example image is invariable then do not upgrade basically during use, does not perhaps carry out aperiodicity relatively continually when comprising the corresponding serviceability of device of interferometric modulator display 200 and upgrade to activate one when (for example) user selects an icon.Yet,, will be generally periodically character to the more new demand of the image in second district 204 corresponding to the periodicity framing of video data shown in second district 204.Yet, for the renewal that provides for the image in first district 202, can easily implement in asynchronous mode to the renewal of image shown in second district 204.In addition, in certain embodiments, each district can overlap, and promptly specifies a district to be positioned at the overlapping part in the top and the district below the covering in another district, thereby an interferometric modulator can be contained in two or more districts.For example, when display 200 being divided into one first district and one second district, one first a plurality of interferometric modulators can be corresponding to second district corresponding to first district and one second a plurality of interferometric modulators, and the one or more interferometric modulators in described first a plurality of interferometric modulators also can be the interferometric modulator in described second a plurality of interferometric modulators.In such an embodiment, being contained in two interferometric modulators in the district simultaneously refreshes, refreshes with described second a plurality of interferometric modulators during second refresh cycle with described first a plurality of interferometric modulators during one first refresh cycle.One or more districts in the described district can be divided into arbitrary shape, for example square, circle or polygon.
The more new demand of shown image can be different from the more new demand in first district 202 or second district 204 again in the 3rd district 206.For example, in one embodiment, in the 3rd district 206 shown data can comprise for example Email or news content etc. can be by reader/user of device text of reading of scrolling periodically, it shows the frequent updating cycle of the correspondence of image in the 3rd district 206.Yet when the user read shown information, the 3rd district 206 can expend the very long cycle at invariable relatively image usually, does not have the cycle of upgrading thereby show.Therefore, interferometric modulator display 200 can be supported the more new features of marked change in time, for example in update cycle of cycle that shown image does not have renewal during for static state substantially relative two-forty during in image change.Should also be clear that the renewal with respect to data in first district 202 and second district 204, image shown in the 3rd district 206 also can asynchronous mode be implemented to upgrade.
