The spatial light modulator that is used for imaging applications has the different form of many kinds.Transmissive type liquid crystal display (LCD) modulator by the control crystalline material reverse and/or orientation with blocking-up or come light is modulated by light.Reflective spatial light modulator then utilizes different physical effects to control the light quantity that reflexes to imaging surface.The example of this reflective modulator comprises reflective LCD and digital micro-mirror device.

Another example of spatial light modulator is one by interfering the interferometric modulator that light is modulated.Interferometric modulator is the bistable display element, and it uses one to have at least one optical resonator removable or deflectable wall.The color of the constructive interference decision visible light of outgoing in described chamber in the described optics cavity.When described movably wall (being made of metal at least in part usually) during towards described chamber static positive mobile, the interference of light in the described chamber obtains modulation, and should modulation can influence in the color of the light of the front of modulator place's outgoing.At interferometric modulator is under the situation of direct-viewing type device, and described front normally manifests the surface of the image of being seen by the observer.

Fig. 1 shows the networked system according to an embodiment.One server 2 (for example Web server) but be coupled to a network 3 with mode of operation.Server 2 can be corresponding to a Web server, mobile phone server, push mail server and similar service device.Network 3 can include spider lines or wireless network, for example WiFi network, mobile telephone network, blueteeth network and similar network.

Network 3 can mode of operation be coupled to various devices.The example that can be coupled to the device of network 3 comprises computer (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-hold type PC, global positioning system (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.Bright opening (on) or open under (open) state, display element reflexes to the user with most of incident visible light.Be in dark (close (off) or close (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 of "on" and "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 first-class axle figure, 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 reflector, 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 reflector.In one embodiment, one of them reflector can be moved between the two positions.Be referred to herein as on the primary importance of release condition, 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 reflector, 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, 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 unit, 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 (and column electrode, local reflex layer 16a, 16b quadrature) and and be deposited on the series of parallel band that the middle expendable material between the pillar 18 constitutes.After expendable material was etched, these deformable metal levels separated with the air gap 19 of the metal level of fixing by a regulation.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 unit.

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 12a among Fig. 2.Yet after a selected row and column applies potential difference, the capacitor that forms at the respective pixel place of described row and column electrode intersection becomes charged state, 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 polarity that is applied, the behavior is all identical.In this way, the may command reflection is similar in many aspects to row/row excitation used in traditional LCD and other Display Techniques with respect to the row/row excitation of non-reflection interference type modulator state.

Fig. 3 to Fig. 5 shows that one uses the exemplary methods and the system of an interferometric modulator array in a display application.Yet these method and system also can be applicable to other displays, for example plasma scope, EL, OLED, STNLCD and TFTLCD.

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, then will disappear in second part at image shown on (for example) plasma scope, EL, OLED, STNLCD and the TFTLCD panel.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 under situation about not refreshing under arbitrary state in the two states, thereby can 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 unit need use one or more controllers and drive circuit correctly to control this display unit usually.Drive circuit for example is used to drive the drive circuit of LCD, can directly be bonded to display floater self and along the location, edge of display floater self.Perhaps, drive circuit can be installed on display floater (in its edge) is connected on the flexible circuit element of remainder of an electronic system.In either case, driver all is usually located at the interface of display floater 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, Pentium ^, Pentium II ^, Pentium III ^, PentiumIV ^, Pentium ^Pro, 8051, MIPS ^, Power PC ^, ALPHA ^, 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, and 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 interface 27 comprises 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, and driving governor 29 is connected to array driver 22 and frame buffer 28 again.In certain embodiments, processor 21 also is connected to array driver 22.Array driver 22 is connected to and drives array of display 30.Each assembly shown in Fig. 3 A shows the structure of an interferometric modulator display.Yet this structure also can use with lcd controller and driver in LCD.As shown in Figure 3A, driving governor 29 is connected to processor 21 by a bus 36 in parallel.Although a driving governor 29 (a for example lcd controller) usually as one independently integrated circuit (IC) be associated with system processor 21, these controllers can make up by many kinds of modes.It can be used as hardware and is embedded in the processor 21, is embedded in the processor 21 or fully-integrated with example, in hardware and array driver 22 as software.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 picture element matrix 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 "), I ²C bus, universal serial bus or any other interface that can have.In the embodiment shown in Fig. 3 A, processor 21 provides array 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 sent 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 determine and the video of input should be sent to processor 21 or array driver 22.

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, I ²C 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.It will be understood by one of ordinary skill in the art that and to 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 the time interval that is generally used for vertical blanking delay and/or horizontal blanking delay, allow the transfer of data of automatic network interface 27, control the timing of described transfer of data 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 uses for example (I between integrated circuit ²C) universal serial bus such as bus or serial peripheral interface (SPI) bus transmits.Yet, should also be clear that when the display of for example other types, also can 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 structure 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.

As shown in Figure 3A, in one embodiment, array driver 22 comprises a horizontal drive circuit 24 and the column drive circuit 26 that signal is provided to a pixel array of display 30.Array section shown in Fig. 2 illustrates with line 1-1 in Fig. 3 A.For the MEMS interferometric modulator, described row/row excitation protocol can utilize the hysteresis property of these devices shown in Fig. 4 A.It for example may need, and one 10 volts potential difference makes a displaceable layers be deformed into actuated state from release condition.Yet, when described voltage when this value reduces, reduce when being back to below 10 volts at described voltage, described displaceable layers will keep its state.In the exemplary embodiment shown in Fig. 4 A, before voltage drop was low to moderate below 2 volts, displaceable layers can not discharge fully.Therefore, in the example shown in Fig. 4 A, exist one to be approximately the voltage range that 3-7 lies prostrate, exist one to apply voltage window in this voltage range, described device is stabilized in and discharges or actuated state in this window.Be referred to as " lag windwo " or " stability window " in this article.

For an array of display with hysteresis characteristic shown in Fig. 4 A, OK/the row excitation protocol can be designed to be expert at during the gating, the pixel that is energized is applied about 10 a volts voltage difference to selected in current, and to d/d pixel being applied one near 0 volt voltage difference.After gating, it is poor to apply about 5 a volts steady state voltage to pixel, and gating makes its residing any state so that its maintenance is expert at.After being written into, in this example, each pixel is all born one and is in " stability window " interior potential difference that 3-7 lies prostrate.This characteristic makes pixel design shown in Figure 2 be stabilized in an existing energized condition or release condition under identical the voltage conditions that applies.Because each pixel of interferometric modulator, no matter be in energized condition or release condition, in fact all be one by described fixed reflector and capacitor that mobile reflector constituted, therefore, this stable state can be kept under the voltage in the lag windwo and consumed power hardly.If the current potential that is applied is constant, then there is not electric current to flow into pixel basically.

In the typical case uses, can be by determining that according to one group of desired actuated pixels in first row one group of row electrode forms a display frame.After this, a horizontal pulse is put on the electrode of the 1st row, thereby encourage the pixel corresponding with determined alignment.After this, determined one group of row electrode is become corresponding with desired one group of actuated pixels in second row.After this, with a pulse put on the 2nd the row electrode, thereby according to determined row electrode encourage the 2nd the row in respective pixel.The pixel of the 1st row is not subjected to the influence of the pulse of the 2nd row, thereby the state that keeps it to set at the impulse duration of the 1st row.The property mode repeats above-mentioned steps to the row of whole series in order, to form described frame.Usually, repeating this process continuously by the speed with a certain desired frame number/second comes with the new video Refresh Data and/or upgrades these frames.Also have a variety of row and the row electrodes that are used to drive pel array to be known also and can be used by people with the agreement that forms the array of display frame.
