Fig. 2 uses the exemplary processes and the system of interferometric modulator array in display application to 5B explanation.
Fig. 2 is the system block diagram that explanation can be incorporated an embodiment of the electronic installation that each side of the present invention is arranged into.In described one exemplary embodiment, described electronic installation comprises processor 21, and it can be any general purpose single-chip or multicore sheet microprocessor (for example ARM, Pentium , Pentium II , Pentium III , Pentium IV , Pentium Pro, 8051, MIPS , Power PC , ALPHA ), or any special microprocessor (for example digital signal processor, microcontroller or programmable gate array).As way conventional in this technology, processor 21 can be configured to carry out one or more software modules.Except executive operating system, described processor can be configured to carry out one or more software applications, comprises web browser, telephony application, e-mail program or any other software application.
In one embodiment, processor 21 also is configured to be communicated with array driver 22.In one embodiment, described array driver 22 comprises row driver circuits 24 and the column driver circuit 26 that signal is provided to display array or panel 30.The xsect of in Fig. 2, showing array illustrated in fig. 1 with line 1-1.For the MEMS interferometric modulator, OK/the row activated protocol can utilize the hysteresis property of these devices illustrated in fig. 3.May need the potential difference (PD) of (for example) 10 volts to impel displaceable layers to be deformed into state of activation from relaxed state.Yet, when voltage when described value reduces, displaceable layers is kept its state when voltage drop is returned below 10 volts.In the one exemplary embodiment of Fig. 3, displaceable layers is just lax fully when voltage drops to below 2 volts.Therefore, have about 3 to 7V voltage range in example illustrated in fig. 3, have a kind of voltage window that applies in described scope, device all is stable in relaxed state or state of activation in described window.This window is referred to herein as " lag windwo " or " stability window ".For the display array of hysteresis characteristic with Fig. 3, can design row/row activated protocol so that during the gating of being expert at, pixel to be activated was exposed to about 10 volts voltage difference during gating was capable, and pixel to be relaxed is exposed to the voltage difference near zero volt.After gating, it is poor that described pixel is exposed to about 5 volts steady state voltage, makes in its residing any state so that it keeps the gating of being expert at.In this example, each pixel experiences the potential difference (PD) in " stability window " of 3-7 volt after being written into.This feature makes pixel design illustrated in fig. 1 activate or lax being pre-stored in all is stable under the state identical apply under the voltage conditions.Because each pixel of interferometric modulator (activating or relaxed state no matter be in) is the capacitor that is formed by fixed reflector and mobile reflection horizon in essence, thereby can keep this steady state (SS) and almost inactivity consumption under the voltage in lag windwo.In essence, fix, do not have electric current to flow in the pixel so if apply voltage.
In the typical case uses, can be by confirming that according to required group activation pixel in first row described group of row electrode produces display frame.Then horizontal pulse is applied to row 1 electrode, thereby activates pixel corresponding to the alignment of being confirmed.Then change described group and confirmed that the row electrode is with corresponding to required group activation pixel in second row.Then pulse is applied to row 2 electrodes, thereby activates suitable pixel in the row 2 according to confirmed row electrode.Row 1 pixel is not influenced by row 2 pulses, and maintains in the state that its 1 impulse duration of being expert at is set.Can be in a continuous manner the row of whole series be repeated this process to produce frame.Usually, repeating this process continuously by the speed with a certain requisite number purpose of per second frame to refresh and/or upgrade described frame with new video data.The row and column electrode that is used to drive pel array also is well-known and can uses in conjunction with the present invention with the agreement of the broad variety that produces display frame.
Fig. 4,5A and 5B explanation are used for forming a possible activated protocol of display frame on 3 * 3 arrays of Fig. 2.One group of possible row of the hysteresis curve that Fig. 4 explanation can be used for making pixel show Fig. 3 and row voltage level.In Fig. 4 embodiment, activate pixel and relate to suitable row are set at-V Bias, and will suitably go and be set at+Δ V, its respectively can corresponding to-5 volts with+5 volts.Relax pixels is to be set at+V by will suitably being listed as Bias, and will suitably go and be set at identical+Δ V, realize thereby on pixel, produce zero volt potential difference (PD).The voltage of being expert at maintains in those row of zero volt, no matter row are in+V BiasStill-V Bias, all be stable in the pixel what initial residing state in office.Same as illustrated in fig. 4, will understand, can use the polarity voltage opposite with above-mentioned voltage, for example, the activation pixel can relate to and being set at+V suitably being listed as Bias, and will suitably go and be set at-Δ V.In this embodiment, discharging pixel is to be set at-V by will suitably being listed as Bias, and will suitably go and be set at identical-Δ V, realize thereby on pixel, produce zero volt potential difference (PD).
Fig. 5 B is a sequential chart of showing a series of row and column signals of 3 * 3 arrays be applied to Fig. 2, described row and column signal will produce the display layout that illustrates among Fig. 5 A, and the pixel that wherein is activated is non-reflection.Before the frame that illustrates in to Fig. 5 A write, pixel can be in any state, and in this example all the row all be in 0 volt, and all row all be in+5 volts.Apply under the voltage condition having these, all pixels all are stable in its existing activation or relaxed state.
In the frame of Fig. 5 A, pixel (1,1), (1,2), (2,2), (3,2) and (3,3) are activated.In order to realize this purpose, during be expert at 1 " line time ", row 1 and 2 are set at-5 volts, and row 3 are set at+5 volts.Because all pixels all are retained in the stability window of 3-7 volt, so this does not change the state of any pixel.Then use from 0 and be raised to 5 volts and turn back to zero pulse and come gating capable 1.This has activated (1,1) and (1, the 2) pixel and (1, the 3) pixel that relaxed.Other pixel is all unaffected in the array.In order to set row 2 as required, row 2 are set at-5 volts, and row 1 and 3 are set at+5 volts.The same strobe that is applied to row 2 then will activate pixel (2,2) and relax pixels (2,1) and (2,3).Equally, other pixel is all unaffected in the array.Set row 3 similarly by row 2 and 3 being set at-5 volts and row 1 are set at+5 volts.Row 3 strobe sets row 3 pixels are as shown in Fig. 5 A.After frame was write, the row current potential was zero, and the row current potential can maintain+5 or-5 volts, and display is stable in the layout of Fig. 5 A so.To understand, same program can be used to have the array of tens of or hundreds of row and columns.Also will should be appreciated that, the sequential, sequence and the level that are used to carry out the voltage that row and column activates can extensively change in the General Principle of above being summarized, and above example only is exemplary, and any activation voltage method all can be used with system and method described herein.

CONSTRUCTED SPECIFICATION according to the interferometric modulator operated of principle of above statement can extensively change.For instance, Fig. 7 A-7E illustrates five different embodiment of removable reflection horizon 14 and supporting construction thereof.Fig. 7 A is the xsect of the embodiment of Fig. 1, and wherein strip of metal material 14 is deposited on the support member 18 of quadrature extension.In Fig. 7 B, removable reflection horizon 14 only is attached to support member at the corner place on tethers 32.In Fig. 7 C, removable reflection horizon 14 is folded down from the deformable layer 34 that can comprise the flexible metal.Described deformable layer 34 is connected to directly or indirectly around the substrate 20 of the periphery of deformable layer 34.These web members are called as pillar in this article.The embodiment that illustrates among Fig. 7 D has post plugs 42, and deformable layer 34 rests on the described post plugs 42.Shown in Fig. 7 A-7C, removable reflection horizon 14 keeps being suspended in the top, chamber, but deformable layer 34 does not form described pillar by the hole of filling between deformable layer 34 and the Optical stack 16.But pillar is formed by the smoothing material that is used to form post plugs 42.The embodiment that illustrates among Fig. 7 E is based on the embodiment that shows among Fig. 7 D, but also can be suitable among the embodiment that in Fig. 7 A-7C, illustrates and the not shown extra embodiment any one work.In the embodiment shown in Fig. 7 E, used the additional layer of metal or other conductive material to form bus structure 44.This allows signal to send along the back side of interferometric modulator, thereby eliminates the possible electrode that must be formed on the substrate 20 of many scripts.
In the embodiment of those embodiment for example shown in Figure 7, interferometric modulator serves as the direct viewing device, wherein watches image from the front side of transparent substrates 20, described side with above to be furnished with that side of modulator relative.In these embodiments, the several portions of interferometric modulator is covered in reflection horizon 14 with optical mode on that side relative with substrate 20 in reflection horizon, comprise deformable layer 34 and bus structure 44.This permission is configured and operates shaded areas and can negatively not influence picture quality.This separable modulator structure allows to select to be used for the structural design of the dynamo-electric aspect of modulator and optics aspect and material and makes it independently of one another and play a role.In addition, the embodiment shown in Fig. 7 C-7E has the additional benefit that the optical property that is derived from reflection horizon 14 and its engineering properties break away from, and described benefit is carried out by deformable layer 34.This structural design and material that allows to be used for reflection horizon 14 is able to optimization aspect optical property, and is used for the structural design of deformable layer 34 and material is being able to optimization aspect the engineering properties of expectation.
Discuss referring to Fig. 1 as mentioned, modulator 12 (that is, modulator 12a and 12b) comprises the optics cavity that is formed between mirror 14 (that is, mirror 14a and 14b) and 16 (being respectively mirror 16a and 16b).The characteristic distance of optics cavity or effectively optical path length d determine optics cavity and the therefore resonance wavelength of interferometric modulator 12.The peak value resonance visible wavelength λ of interferometric modulator 12 is substantially corresponding to the aware colors by the light of modulator 12 reflection.Arithmetically, optical path length d equals  N λ, and wherein N is an integer.Therefore, given resonance wavelength is by interferometric modulator 12 reflections of the optical path length d with  λ (N=1), λ (N=2), 3/2 λ (N=3) etc.Integer N can be called as catoptrical order of interference.As used herein, when mirror 14 was at least one position, the level of modulator 12 was also referred to as the level N by the light of modulator 12 reflections.For instance, the red interferometric modulator 12 of the first order can have the optical path length d of about 325nm, and it is corresponding to the wavelength X of about 650nm.Therefore, the red interferometric modulator 12 in the second level can have the optical path length d of about 650nm.Usually, the light (for example, having higher " Q " value) in the narrower wavelength coverage of higher modulator 12 reflections, and therefore produce more saturated colorama.The character (for example colour gamut of display and white point) of effect of saturation degree display that comprises the modulator 12 of colour element.For instance, to use the display of second level modulator 12 to have identical white point or colour balance in order making, can to select second level modulator 12 to make it have different central peak optical wavelengths with the display of the first order modulator that comprises catoptrical identical cardinal principle color.
Fig. 8 is the side cross-sectional view of exemplary interferometric modulator 12, and its explanation meeting is by being positioned at removable mirror 14 spectral characteristic of the light of exporting at 61-65 place, a series of position.Described exemplary modulator comprises tin indium oxide (ITO) conductive layer 52 that serves as the row electrode.In exemplary modulator, removable mirror 14 comprises column conductor.
Among the position 61-65 of the particular demographic of removable mirror 14 each is showed by the arrow that extends from fixed mirror 16.Specific one among the position 61-65 of removable mirror indicated at the tip of each arrow.Definite from the color of the light of interferometric modulator reflection by the optical path length d between removable mirror 14 and the fixed mirror 16.Chosen distance 61-65 is so that calculate thickness and the refractive index of dielectric layer 54 in optical path length d.Therefore, the removable mirror 14 that is positioned at a diverse location place among the position 61-65 (each is corresponding to different distance d) can cause with different spectral responses light being outputed to the modulator 12 of inspecting position 51, and described spectral response is corresponding to just by the incident light of the different colours of modulator 12 reflection.In addition, 61 places in the position, removable mirror 14 makes interference effect to be left in the basket fully near fixed mirror 16, and modulator 12 serves as the incident visible light (for example) that equally the reflects all colours substantially substantially mirror as white light.Cause that broadband mirror effect is because too little the optical resonance of small distance d in visible band.Therefore mirror 14 only serves as the reflecting surface with respect to visible light.
Be positioned at mirror 14 under the situation at 62 places, position, modulator 12 shows gray shade, because the clearance distance of the increase between mirror 14 and 16 has reduced the reflectivity of mirror 14.63 places in the position make the chamber interfere the ground operation apart from d but do not reflect the light of any visible wavelength substantially, because resonance wavelength is outside visible range.
D further increases along with distance, and the peak spectral response of modulator 12 moves in the visible wavelength.Therefore, when removable mirror 14 is in 64 places, position, modulator 12 reflect blue.When removable mirror 14 is in 65 places, position, modulator 12 reflect green light.When removable mirror 14 is in non-deviation position 66 places, modulator 12 reflect red.
In the process that designs the display that uses interferometric modulator 12, can form modulator 12 so that increase catoptrical color saturation.Saturation degree refers to the tone intensity of colorama.HI SA highly saturated tone has lively strong color, and undersaturated tone is revealed as softer and be grey.For instance, producing very, the laser of the wavelength of close limit produces HI SA highly saturated light.On the contrary, typical incandescence bulb produces and can have unsaturated redness or blue white light.In one embodiment, modulator 12 form have corresponding to more senior interference (for example, the second level or the third level) apart from d to increase the saturation degree of reflect color light.
Exemplary color monitor comprises redness, green and blue display element.In this class display, produce other color by the relative intensity that changes the light that produces by redness, green and blue element.For example this kind mixing of red, green and blue primary colours is perceived as other color by human eye.Redness in this type of color system, green and blue relative value can be called as the tristimulus value(s) of the excitation of the responsive part of redness, green and blue light about human eye.In general, primary colours are saturated more, and the scope of the color that can be produced by display is also just big more.In other embodiments, display can comprise the modulator 12 with some groups of colors, and described some groups of colors define other color system according to some groups of primary colours except that red, green and blue.
The another consideration that design is incorporated in the display that interferometric modulator 12 is arranged is the generation of white light." in vain " light generally refers to by human eye and is perceived as the light that does not comprise any particular color, and promptly white light is not associated with tone.Black refers to and lacks color (or light), and white refers to and comprises wide spectral range and make the light of perception less than particular color.White light can refer to the light of the wide spectral range visible light with the approximate homogeneous of intensity.Yet, because human eye is for redness, green and the blue light sensitivity of some wavelength, having the light of one or more spectrum peaks with generation so can produce white by the mixed colors light intensity, it is perceived as " white " by eyes.The colour gamut of display be device can (for example) by mixing the color gamut that redness, green and blue light are regenerated.
In reflected displaying device, the white light that uses saturated interferometric modulator to produce often has relatively low intensity concerning the person of inspecting, because incident wavelength only among a small circle forms white light with relative higher-strength reflection.As a comparison, the mirror of reflection wideband white (for example, all incident wavelengths) substantially has than hard intensity, because reflection incident wavelength in a big way.Therefore, by using primary colours combination results white light to come design reflectivity formula display to cause trading off between the brightness of color saturation and colour gamut and the white light of display output usually.
In one embodiment, removable mirror 14 makes in primary importance modulator 12, and reflect visible light is not (for example through the location, the position 63 of Fig. 8) distance and in the second place between removable mirror 14 and the fixed mirror 16 is too little for the interference modulations of incident visible light, and make mirror 14 reflect broadband white color (for example, the position 61 of Fig. 8).In this type of embodiment, removable mirror 14 on whole visible spectrum with wide and reflect incident light than the spectral response of homogeneous relatively.If incident light comprises white light, the light that is reflected in the second place by modulator 12 can be substantially similarly white light so.The spectral response of this of modulator 12 " white " reflective condition may be homogeneous substantially on whole visible spectrum.In one embodiment, come tuning spectral response by the material of selecting modulator.For instance, can use different materials (for example aluminium or copper) as the reflecting surface of removable mirror 14 so that the spectral response of tuning modulator 12 when being in white reflective condition.In another embodiment, can use filtrator optionally to absorb the reflection of some wavelength or incident light to realize the output of this broadband white color modulator.
In an embodiment of pel array 30, each pixel comprises one or more colour modulators 12 (for example being configured to the modulator of reflection Red, green and blue light) and one or more are configured to " white " modulator 12 of reflected white-light.In this embodiment, the light from the redness that is in reflective condition, green and/or blue modulator 12 makes up with the output colorama.Light from white modulator 12 can be used for output white or grey coloured light.Use white and color combinations can increase the brightness or the intensity of pixel.
The white point of display is to think the tone that is generally neutral (grey or colourless).Can be based on comparing the characteristic of the white point that shows display equipment by the spectral content that installs white light that produces and the light of under specified temp, launching (" dark volume radiation ") by dark volume.The dark volume radiator is idealized object, and its absorption is incident on all light on the described object and it launches described light again with the spectrum that depends on the dark volume temperature.For instance, the dark volume spectrum under 6,500 ° of K can be called as the white light of the colour temperature with 6,500 ° of K.The colour temperature or the white point that it has been generally acknowledged that these approximate 5,000 ° of-10,000 ° of K are consistent with daylight.
International lighting association (CIE) announces the standardization white point of light source.For instance, light source label " d " refers to daylight.In particular, relevant with the colour temperature of 5,500 ° of K, 6,500 ° of K and 7,500 ° of K standardization white point D 55, D 65And D 75It is standardization daylight white point.
The white point of the white light that display equipment can be produced by display is as feature.The same with light from other light source, to the human perception of display at least in part by the perception from the white light of display is determined.For instance, (for example, display D55) or light source can be perceived as by the person of inspecting and have yellow tone to have low white point.(for example, display D75) can be perceived as concerning the user and have " colder " or than blue cast to have the higher temperature white point.The user responds more satisfactorily to the display with higher temperature white point usually.Therefore, the white point of control display provides certain control for the person of inspecting to the response of display satisfactorily.The embodiment of interferometric modulator array 30 can be configured to produce white light, wherein selects white point to meet the standardization white point under one or more expection illumination conditions.
Can produce white light by comprise one or more interferometric modulators 12 at each pixel by pel array 30.For instance, in one embodiment, pel array 30 comprises the pixel of the group of redness, green and blue interferometric modulators 12.Discuss as mentioned, can concern that d= N λ selects optical path length d to select the color of interferometric modulator 12 by using.In addition, the balance of the color that each pixel produced or relative scale can further be subjected to each relative reflector space influence in the interferometric modulator 12 (for example red, green and blue interferometric modulators 12) in the pel array 30.In addition, because modulator 12 optionally reflects incident light, so depend on the spectral characteristic of incident light usually from the catoptrical white point of the pel array 30 of interferometric modulator 12.In one embodiment, catoptrical white point can be configured to different with the white point of incident light.For instance, in one embodiment, pel array 30 can be configured to reflection D75 light when being used for D65 sunlight.
In one embodiment, in the pel array 30 white light that produces through selecting so that by pel array 30 apart from d and zone of interferometric modulator 12 corresponding under the expection illumination condition (for example, in the sun, under fluorescence, or the location of hanging oneself is with the front lighting of illumination images pixel array 30) the specific criteria white point.For instance, under the particular light condition, the white point of pel array 30 may be selected to be D 55, D 65Or D 75In addition, the light by pel array 30 reflections can have different white points with the light of expection or the light source that is configured.For instance, specific pixel array 30 can be configured to reflection D75 light when inspecting under D65 sunlight.More generally, can select the white point of display with reference to the light source that disposes with display (for example, front lighting) or with reference to the specific condition of inspecting.For instance, display can be configured to have selected white point (for example, D55, D65 or D75) under the expection of for example incandescent, fluorescence or lamp or typical illumination source when inspecting.More particularly, the display that is used for (for example) hand-held device can be configured to have selected white point under sunlight conditions when inspecting.Perhaps, the display that is used for office environment can be configured to have selected white point (for example, D75) by the fluorescent illumination of typical office the time.In various embodiments, the different distance d that can select modulator 12 and zone are to produce at different other standardization white point settings of inspecting environment.In addition, also may command redness, green and blue modulator 12 continue the different time amount so that it is in reflection or the non-reflective state, so that further change the relative equilibrium of redness, green and the blue light of reflection, and therefore change catoptrical white point.In one embodiment, can select each the ratio of reflector space in the colour modulator 12 so that inspect in the environment the described white point of control in difference.In one embodiment, can select optical path length d so that (for example corresponding to visible resonance wavelength more than one, red, green and blue first, second or third level peak value) common multiple so that interferometric modulator 12 reflections are with three white lights that peaks visible is a feature in the spectral response.In this embodiment, can select optical path length d, so that the white light that is produced is corresponding to the standardization white point.
The group of redness, green and blue interferometric modulators 12, other embodiment comprises the alternate manner that produces white light in pel array 30.For instance, pel array 30 embodiment comprises cyan and yellow interferometric modulator 12 (for example, having the interferometric modulator 12 of individual separation apart from d) so that produce cyan and sodium yellow.The combination spectrum response of cyan and yellow interferometric modulator 12 produces the light with wide spectral response that is perceived as " white ".Cyan and yellow modulator are closely located, so that this array response of the person's of inspecting perception.For instance, in one embodiment, cyan modulator and yellow modulator are arranged in the adjacent row of pel array 30.In another embodiment, cyan modulator and yellow modulator are arranged in the adjacent column of pel array 30.
Fig. 9 is the curve map of the spectral response of an explanation embodiment comprising the cyan that is used to produce white light and yellow interferometric modulator 12.Transverse axis is represented catoptrical wavelength.Z-axis represents to be incident on the relative reflectance of the light on the modulator 12.The response of trace 80 explanation cyan modulators, it is the single peak value of the cyan part center (for example, between blueness and green) that is positioned at spectrum.The response of the yellow modulator of trace 82 explanation, it is the single peak value of the yl moiety center (for example, between redness and green) that is positioned at spectrum.The combination spectrum response of trace 84 a pair of cyans of explanation and yellow modulator 12.Trace 84 has two peak values at cyan and yellow wavelengths place, but on whole visible spectrum enough homogeneous, and make the reflected light from these modulators 12 be perceived as white.
Usually, when inspecting modulator 12 from different perspectives, by the color displacement of the light of interferometric modulator 12 reflection.Figure 10 is the side cross-sectional view of interferometric modulator 12, and the different optical path of modulator 12 is passed in its explanation.Can be from the color of the light of interferometric modulator 12 reflection at changing about the different incidents of axle AA (and reflection) angle as shown in Figure 10.For instance, for interferometric modulator shown in Figure 10 12, when light along from the axle path A 1When advancing, light is incident on the interferometric modulator with first angle, from the interferometric modulator reflection, and advances to the person of inspecting.Since the optical interference between a pair of mirror in the interferometric modulator 12, when light arrives the person of inspecting, the person's of inspecting perception first color.Therefore when the person of inspecting moves or change his/her position and change the visual angle, the light that receives by the person of inspecting different along corresponding to the second different incidents (with reflection) angle from the axle path A 2Advance.The optical path length d of the light of propagating is depended in optical interference in the interferometric modulator 12 in modulator.The different optical path A 1And A 2The difference output that therefore produces interferometric modulator 12 of different optical path.Under the situation of visual angle increase, effective optical path of interferometric modulator is according to concerning that 2dcos β=N λ reduces, and wherein β is visual angle (normal of display and the angle between the incident light).Under the situation of visual angle increase, catoptrical peak value resonance wavelength reduces.Therefore the user decides the different color of perception according to his or her visual angle.As indicated above, this phenomenon is called as " gamut ".Usually with reference to when discerning this gamut by the color of interferometric modulator 12 generations when axle AA inspects.
In one embodiment, pel array 30 comprises yellow interferometric modulator of the first order and second level cyan interferometric modulator.When the off-axis angle that increases is gradually inspected this pel array 30, by the indigo plant end skew towards spectrum of the light of the yellow modulator reflection of the first order, the modulator that for example is in a certain angle place has the effective d that equates with effective d of first order cyan modulator.Simultaneously, by the light shift of second level cyan modulator reflection with corresponding to light from the yellow modulator of the first order.Therefore, even when the skew of the relative peak of spectrum, totally make up spectral response also wide and on whole visible spectrum relatively than homogeneous.Therefore this pel array 30 produces white light in the visual angle of relatively large scope.
In one embodiment, the display with cyan and yellow modulator can be configured to inspect at one or more and produce the white light with selected standardization white point under condition.For instance, can select the spectral response of cyan modulator and yellow modulator, so that under the selected lighting condition of the D55, the D65 that comprise the display that is used to be suitable for outdoor use or D75 light (for example sunlight), reflected light has white point or any other suitable white point of D55, D65, D75.In one embodiment, modulator can be configured to reflect the light that has different white with incident light from the expection or the selected condition of inspecting.
Figure 11 has to be used for the side cross-sectional view of interferometric modulator 12 of material layer 102 that optionally transmission has the light of particular color.In an exemplary embodiment, on that side relative that layer 102 is in substrate 20 with modulator 12.In one embodiment, material layer 102 comprises and inspects the magenta filtrator that green interferometric modulator 12 is passed.In one embodiment, material layer 102 is a coloring material.In this type of embodiment, described material is the dyeing photo anti-corrosion agent material.In one embodiment, green interferometric modulator 12 is the green interferometric modulators of the first order.Filtering layer 102 is configured to transmission magenta light with the white-light illuminating of extensive homogeneous the time.In an exemplary embodiment, light is incident on the layer 20, and filtered light is transmitted to modulator 12 from layer 20.Modulator 12 passes through layer 102 reflected back with filtered light.In this type of embodiment, light passes layer 102 for twice.In this type of embodiment, the thickness that can select material layer 102 is to compensate and to utilize this double filtration.In another embodiment, the front lighting structure can be positioned between layer 102 and the modulator 12.In this type of embodiment, material layer 102 only works to the light by modulator 12 reflections.In this type of embodiment, correspondingly select layer 102.
Figure 12 is the curve map that the spectral response of an embodiment who comprises green interferometric modulator 12 and " magenta " filtering layer 102 is described.Transverse axis is represented catoptrical wavelength.Z-axis represents to be incident on the visible spectrum relative spectral response of the light on green modulator 12 and the filtering layer 102.The response of trace 110 explanation green modulator 12, it is near the single peak value of the green portion center (for example, the center of visible spectrum) that is positioned at spectrum.Trace 112 illustrates the response of the magenta filtrator that is formed by material layer 102.Trace 112 has the part of two relatively flats at the either side of center u shape minimum value.Therefore trace 112 represents the response of magenta filtrator, transmission all redness and blue light substantially optionally in the light of described magenta filtrator in filtering spectrum green portion.Trace 114 explanation green modulator 12 respond with the combination spectrum of filtering layer 102 pairings.The cause that trace 114 explanations are filtered owing to 102 pairs of light of filtering layer, the spectral response of described combination is in lower reflectivity levels than green modulator 12.Yet, spectral response on whole visible spectrum relatively than homogeneous, so that be perceived as white from the filtered reflected light of green modulator 12 and magenta filtering layer 102.
In one embodiment, the display with green modulator 12 and magenta filtering layer 102 can be configured to inspect at one or more and produce the white light with selected standardization white point under condition.For instance, can select the spectral response of green modulator 12 and magenta filtering layer 102, so that under the selected lighting condition of the D55, the D65 that comprise the display that is used to be suitable for outdoor use or D75 light (for example sunlight), reflected light has white point or any other suitable white point of D55, D65, D75.In one embodiment, modulator 12 and filtering layer 102 can be configured to reflect the light that has different white with incident light from the expection or the selected condition of inspecting.
