随着显示器在移动装置中的使用变得更加普及且这些装置具有不断增加的功能,需要拥有具有低功率消耗的显示器。 As displays used in mobile devices and these devices are becoming more prevalent with increasing functions, we need to have a display with low power consumption. 此外,需要估计各种图像的显示期间这些显示器所消耗的功率使得可准确地理解并适应移动装置的功率要求。 Further, the estimated required power during these displays various images displayed consumed by such adaptation can be accurately understood and power requirements of the mobile device. 因此,提供用于确定由给定显示器所消耗的功率(包含接通或断开的和不同颜色的像素所消耗的功率)的方法。 Thus, there is provided a method for determining the power consumed by a given display (power comprises turning on or off of pixels of different colors and consumed) a. 提供一种用于准确地测量功率的系统。 It provided a method for accurately measuring the power of the system. 此外,提供建模显示器上显示的给定图像所消耗的功率的方法和系统。 Further, there is provided a method and system power consumption for a given image displayed on the display modeling.

图1中说明包括干涉仪MEMS显示元件的一个干涉仪调制器显示器的实施例。 In Figure 1 a described embodiment comprises an interferometer modulator display element interferometer MEMS display. 在这些装置中,像素处于明亮状态或黑暗状态。 In these devices, the pixels are in either a bright or dark state. 在明亮(“接通”或“开启”)状态下,显示元件将入射可见光的大部分反射到用户。 In the bright ( "on" or "open") state, the display element reflects a large portion of incident visible light to a user. 当在黑暗(“断开”或“关闭”)状态下时,显示元件将极少的入射可见光反射到用户。 When in the dark ( "off" or "closed") state, the display element little incident visible light to a user. 依据实施例而定,可颠倒“接通”和“断开”状态的光反射性质。 Based on the embodiment, may be reversed, "ON" and the light reflectance properties of the "off" state. MEMS像素可经配置而主要在选定的颜色处反射,从而允许除了黑白显示以外的彩色显示。 MEMS pixels can be configured predominantly at selected colors at reflection, allowing for a color display in addition to black and white display.

图1是描述视觉显示器的一系列像素中的两个相邻像素的等角视图,其中每一像素包括MEMS干涉仪调制器。 FIG 1 is an isometric view depicting two adjacent pixels in a series of pixels of a visual display described, wherein each pixel comprises a MEMS interferometric modulator device. 在一些实施例中,干涉仪调制器显示器包括这些干涉仪调制器的一行/列阵列。 In some embodiments, an interferometric modulator display device comprising such an interferometer modulators row / column array. 每一干涉仪调制器包含一对反射层,其定位成彼此相距可变且可控制的距离以形成具有至少一个可变尺寸的谐振光学腔。 Each interferometer modulator includes a pair of reflective layers positioned at a variable and controllable distance from each other a distance to form a resonant optical cavity having at least one variable dimension. 在一个实施例中,可在两个位置之间移动所述反射层之一。 In one embodiment, one of the reflective layers may be moved between the two positions. 在第一位置(本文中称为松弛位置)中,可移动反射层定位成距固定部分反射层相对较大的距离。 (Referred to herein as the relaxed position) in the first position, the movable reflective layer is positioned from a fixed partially reflective layer is a relatively large distance. 在第二位置(本文中称为激活位置)中,可移动反射层定位成更紧密邻近所述部分反射层。 (Referred to herein as the actuated position) in the second position, the movable reflective layer is positioned more closely adjacent to the partially reflective layer. 视可移动反射层的位置而定,从所述两个层反射的入射光建设性地或破坏性地进行干涉,从而为每一像素产生全反射状态或非反射状态。 Depending on the position of the movable reflective layer may be, from the two layers interferes constructively or destructively incident light is reflected, resulting in total reflection state or non-reflective state for each pixel.

图1中像素阵列的所描绘部分包含两个相邻干涉仪调制器12a和12b。 The depicted portion of the pixel array in Figure 1 includes two adjacent interferometric modulators device 12a and 12b. 在左侧干涉仪调制器12a中,说明可移动反射层14a处于距包含部分反射层的光学堆叠16a预定距离处的松弛位置中。 In the left interferometer modulator 12a, a movable reflective layer 14a is away from an optical stack comprising a partially reflective layer 16a in a relaxed position at a predetermined distance in. 在右侧干涉仪调制器12b中,说明可移动反射层14b处于邻近于光学堆叠16b的激活位置中。 In the right interferometer modulator 12b, the movable reflective layer 14b is illustrated in an actuated position adjacent to the optical stack 16b.

如本文所引用的光学堆叠16a和16b(统称为光学堆叠16)通常包括若干熔合层(fusedlayer),所述熔合层可包含例如氧化铟锡(ITO)的电极层、例如铬的部分反射层和透明电介质。 The optical stacks 16a cited herein and 16b (collectively referred to as optical stack 16) typically comprise several fused layers (fusedlayer), the fused layer may comprise, for example, indium tin oxide (ITO) electrode layer, a partially reflective layer, for example, chromium and a transparent dielectric. 因此,光学堆叠16是导电的、部分透明且部分反射的,且可通过(例如)将上述层的一者或一者以上沉积到透明衬底20上来制造。 Thus, the optical stack 16 is thus electrically conductive, partially transparent and partially reflective, and may be by (e.g.) the above-mentioned one or more layers deposited onto a transparent substrate 20.. 在一些实施例中,所述层经图案化成为多个平行条带,且如下文中进一步描述,可在显示装置中形成行电极。 In some embodiments, the layers are patterned into parallel strips, and as described further below, may form row electrodes in a display device. 可移动反射层14a、14b可形成为沉积金属层(一层或多层)的一系列平行条带(与行电极16a、16b垂直),所述金属层沉积在柱18和沉积于柱18之间的介入牺牲材料的顶部上。 The movable reflective layers 14a, 14b may be formed of a deposited metal layer (one or more) of a series of parallel strips (row electrodes of 16a, 16b), the metal layer is deposited in a column 18 and column 18 is deposited on the between the intervention on top of the sacrificial material. 当蚀刻去除牺牲材料时,可移动反射层14a、14b通过所界定的间隙19而与光学堆叠16a、16b分离。 When the sacrificial material is etched away, the movable reflective layers 14a, 14b by a defined gap 19 with the optical stacks 16a, 16b separated. 例如铝的高度导电且反射的材料可用于反射层14,且这些条带可在显示装置中形成列电极。 Highly conductive and reflective material such as aluminum may be used for the reflective layers 14, and these strips may form column electrodes in a display device.

在不施加电压的情况下,腔19保留在可移动反射层14a与光学堆叠16a之间,其中可移动反射层14a处于机械松弛状态,如图1中像素12a所说明。 In the case of no applied voltage, the cavity 19 remains between the movable reflective layer 14a and optical stack 16a, with the movable reflective layer 14a in a mechanically relaxed state, as shown in pixel 12a. 然而,当将电位差施加到选定的行和列时,形成在相应像素处的行电极与列电极的交叉处的电容器变得带电,且静电力将所述电极拉在一起。 However, when a potential difference is applied to a selected row and column, the capacitor formed at the intersection becomes charged at the electrodes at the corresponding pixel row and column electrodes, and electrostatic forces pull the electrodes together. 如果电压足够高,那么可移动反射层14变形且被迫抵靠光学堆叠16。 If the voltage is high enough, the movable reflective layer 14 is deformed and is forced against the optical stack 16. 光学堆叠16内的介电层(在此图中未图示)可防止短路并控制层14与16之间的分离距离,如图1中右侧的像素12b所说明。 The optical stack of a dielectric layer (not illustrated in this Figure) may prevent shorting and control the separation distance between layers 14 and 16, as shown in the right side of the pixel 1 12b as described in 16. 不管所施加的电位差的极性如何,表现均相同。 Potential difference regardless of the polarity of the applied behavior is the same. 以此方式,可控制反射像素状态对非反射像素状态的行/列激活在许多方面类似于常规LCD和其它显示技术中所使用的行/列激活。 In this manner, the state of the pixel rows can control the reflective vs. non-reflective pixel states / column actuation line similar in many respects to conventional LCD and other display technologies used / column actuation.

The row driver circuit 24 and a column driver circuit 26. 在图2中以线1-1展示图1中说明的阵列的横截面。 In cross-section lines 1-1 in FIG. 1 explained in FIG. 2 array. 对于MEMS干涉仪调制器来说,行/列激活协议可利用图3中说明的这些装置的滞后性质。 For MEMS interferometric modulators, the instrument, the row / column actuation protocol may take advantage of a hysteresis property of these devices illustrated in Figure 3. 可能需要(例如)10伏的电位差来促使可移动层从松弛状态变形为激活状态。 May be required (e.g.) a 10 volt potential difference to cause a movable layer to deform from the relaxed state to the actuated state. 然而,当电压从所述值减小时,可移动层在电压降回10伏以下时维持其状态。 However, when the voltage is reduced from that value, the movable layer maintains its state as the voltage drops back below 10 volts. 在图3的示范性实施例中,可移动层直到电压降到2伏以下时才完全松弛。 Embodiment, the movable layer until the voltage drops below 2 volts does not relax completely in the exemplary embodiment of FIG. 3. 因此在图3中说明的实例中存在约3到7V的电压范围,在所述范围中存在所施加电压的窗口,在所述窗口内装置在松弛状态或激活状态中均是稳定的。 Thus a range of voltage, about 3 to 7V of the example illustrated in FIG. 3, the presence of an applied voltage in said range window, said window means in the relaxed or actuated state are both stable. 此窗口在本文中称为“滞后窗口”或“稳定窗口”。 This window is called "hysteresis window" or "stability window" in this article. 对于具有图3的滞后特性的显示器阵列来说,可设计行/列激活协议使得在行选通期间,已选通行中待激活的像素暴露于约10伏的电压差,且待松弛的像素暴露于接近零伏的电压差。 For a display array having the hysteresis characteristics of Figure 3, the design may be the row / column actuation protocol such that the row strobe period, the selected pixels in the passage to be actuated are exposed to a voltage difference of about 10 volts, the pixels are exposed to be relaxed near zero volts voltage difference. 在选通之后,所述像素暴露于约5伏的稳态电压差使得其维持在行选通使其所处的任何状态中。 After the strobe, the pixels are exposed to a steady state voltage difference of about 5 volts such that they remain in whatever state the row selected from the through-put them in. 在此实例中,每一像素在被写入之后经历3-7伏的“稳定窗口”内的电位差。 In this example, each pixel sees a potential difference within the 3-7 volt "stability window" After being written. 此特征使图1中说明的像素设计在相同的施加电压条件下在激活或松弛预存在状态下均是稳定的。 This feature makes the pixel illustrated in Figure 1 is designed at the same applied voltage conditions in the actuated or relaxed pre-existing state is stable. 因为干涉仪调制器的每一像素(不论处于激活还是松弛状态)本质上是由固定反射层和移动反射层形成的电容器,所以可在滞后窗口内的一电压下维持此稳定状态而几乎无功率消耗。 Since each pixel capacitor (whether in the actuated or relaxed state) is essentially formed by the fixed and moving reflective layers reflective layer interferometer modulator, this stable state can be maintained so that at a voltage within the hysteresis window with almost no power consumption. 本质上,如果所施加的电压是固定的,那么没有电流流入像素中。 Essentially, if the applied voltage is fixed, then no current flows into the pixel.

在典型应用中,可通过根据第一行中所需组的激活像素确认所述组列电极来产生显示帧。 In typical applications, a display frame may be created according to the activation of pixels in the first row to confirm the desired set of the set of column electrodes. 接着将行脉冲施加到行1电极,从而对应于所确认的列线而激活像素。 Row pulse is then applied to the row 1 electrode, corresponding to the activated column line identified pixels. 接着改变所述组已确认列电极以对应于第二行中所需组的激活像素。 Group is then changed to correspond to the column electrodes has confirmed that the desired set of actuated pixels in the second row. 接着将脉冲施加到行2电极,从而根据已确认的列电极而激活行2中的适当像素。 Pulse is then applied to the row 2 electrode, actuating the appropriate pixels in row 2 in accordance with the column electrodes confirmed. 行1像素不受行2脉冲影响,且维持在其在行1脉冲期间被设定的状态中。 Row 1 pixels are unaffected by the row 2 pulse, and remain in the row 1 pulse during the set state. 可以连续方式对整个系列的行重复此过程以产生帧。 This process may be continuously repeated manner for the entire series of rows to produce the frame. 通常,通过以每秒某一所需数目的帧的速度连续地重复此过程来用新的显示数据刷新且/或更新所述帧。 Generally, the speed of a desired number of frames per second, continually repeating this process with new display data are refreshed and / or updated frame. 用于驱动像素阵列的行和列电极以产生显示帧的广泛种类的协议也是众所周知的且可结合本发明使用。 For driving row and column electrodes of pixel arrays to produce display frames are a wide variety of protocols are known and may be used in conjunction with the present invention.

图4、5A和5B说明用于在图2的3×3阵列上形成显示帧的一个可能的激活协议。 FIGS. 4,5A and 5B illustrate one possible actuation protocol formed on a display frame 3 × 3 array of FIG. 2 is used. 图4说明可用于使像素展示出图3的滞后曲线的一组可能的列和行电压电平。 A possible set of column and row voltage levels that may be used in FIG. 4 illustrates the pixel exhibits hysteresis curve of FIG. 3. 在图4实施例中,激活像素涉及将适当列设定为-Vbias,且将适当行设定为+ΔV,其分别可对应于-5伏和+5伏。 In the embodiment of Figure 4, actuating a pixel involves setting the appropriate column to -Vbias, and the appropriate row to + ΔV, which may correspond to -5 volts and +5 volts. 松弛像素是通过将适当列设定为+Vbias,且将适当行设定为相同的+ΔV,从而在像素上产生零伏电位差而实现的。 Relaxing the pixel is accomplished by setting the appropriate column to + Vbias, and the appropriate row to the same + ΔV, producing a zero volt potential difference across the pixel. 在行电压维持在零伏的那些行中,不管列处于+Vbias还是-Vbias,像素在任何其最初所处的状态中均是稳定的。 Row voltage is held at zero volts in those lines, regardless of the column is at + Vbias, or -Vbias, any pixel in its initial state in which are stable. 同样如图4中所说明,将了解,可使用具有与上述电压的极性相反的极性的电压,例如,激活像素可涉及将适当列设定为+Vbias,且将适当行设定为-ΔV。 Also illustrated in FIG. 4, it will be appreciated, it may be a voltage having a polarity opposite to a polarity of the voltage, e.g., actuating a pixel can involve setting the appropriate column to + Vbias, and the appropriate row to - ΔV. 在此实施例中,释放像素是通过将适当列设定为-Vbias,且将适当行设定为相同的-ΔV,从而在像素上产生零伏电位差而实现的。 In this embodiment, releasing the pixel is accomplished by setting the appropriate column to -Vbias, and the appropriate row to the same -AV, producing a zero volt potential difference across the pixel.

图5B是展示施加到图2的3×3阵列的一系列行和列信号的时序图,所述系列的行和列信号将产生图5A中说明的显示器布置,其中被激活像素为非反射的。 Figure 5B is a timing diagram showing a series of row applied to FIG. 2 and 3 × 3 array of column signals, said series of row and column signals will result in the display arrangement illustrated in Figure 5A, where actuated pixels are non-reflective . 在对图5A中说明的帧进行写入之前,像素可处于任何状态,且在本实例中所有行均处于0伏,且所有列均处于+5伏。 Before the frame illustrated in Figure 5A are written, the pixels can be in any state, and in this example, all the rows are at 0 volts, and all the columns are at +5 volts. 在这些所施加的电压的情况下,所有像素在其既有的激活或松弛状态中均是稳定的。 With these applied voltages, all pixels in their existing actuated or relaxed states are stable.

在图5A的帧中,像素(1,1)、(1,2)、(2,2)、(3,2)和(3,3)被激活。 In the Figure 5A frame, pixels (1,1), (1,2), (2,2), (3,2) and (3,3) are actuated. 为了实现此目的,在行1的“线时间(line time)”期间,将列1和2设定为-5伏,且将列3设定为+5伏。 To accomplish this, the row during a "line time (line time)", columns 1 and 2 are set to 1 to -5 volts, and column 3 is set to +5 volts. 因为所有像素均保留在3-7伏的稳定窗口中,所以这并不改变任何像素的状态。 Because all the pixels remain in the 3-7 volt stability window, so it does not change the state of any pixels. 接着用从0升到5伏且返回零的脉冲选通行1。 Followed by from 0, up to 5 volts, and back to zero passage of a selected pulse. 这激活了(1,1)和(1,2)像素且松弛了(1,3)像素。 This actuates the (1,1) and (1,2) pixels and relaxes the (1,3) pixel. 阵列中其它像素均不受影响。 No other pixels in the array are affected. 为了视需要设定行2,将列2设定为-5伏,且将列1和3设定为+5伏。 To set row 2 as desired, column 2 is set to -5 volts, and columns 1 and 3 are set to +5 volts. 施加到行2的相同选通接着将激活像素(2,2)且松弛像素(2,1)和(2,3)。 The same strobe applied to row 2 will then actuate pixel (2,2) and relax pixels (2,1) and (2,3). 同样,阵列中其它像素均不受影响。 Similarly, other pixels in the array are affected. 通过将列2和3设定为-5伏且将列1设定为+5伏来类似地设定行3。 By setting columns 2 and 3 to -5 volts, and column 1 to +5 volts Row 3 is similarly set. 行3选通设定行3像素,如图5A中所示。 The row 3 strobe sets the row 3 pixels as shown in Figure 5A. 在对帧进行写入之后,行电位为零,且列电位可维持在+5或-5伏,且接着显示器在图5A的布置中是稳定的。 After writing the frame, the row potentials are zero, and the column potentials can remain at either +5 or -5 volts, and the display is then stable in the arrangement of Figure 5A. 将了解,可将相同程序用于数十或数百个行和列的阵列。 It will be appreciated that the same procedure can be employed for arrays of dozens or hundreds of rows and columns. 还将应了解,用于执行行和列激活的电压的时序、序列和电平可在上文所概述的一般原理内广泛变化,且上文的实例仅为示范性的,且任何激活电压方法均可与本文描述的系统和方法一起使用。 It will also be appreciated that, for performing the row and column actuation timing, sequence, and levels of voltages can be varied widely within the general principles outlined above, and the above example is exemplary only, and any actuation voltage method It can be used with the systems and methods described herein.

根据上文陈述的原理而操作的干涉仪调制器的结构的细节可广泛变化。 Details of the structure of the interferometer modulators accordance with the principles set forth above may vary widely operated. 举例来说,图7A-7E说明可移动反射层14及其支撑结构的五个不同实施例。 For example, Figures 7A-7E illustrate five different movable Example 14 and the support structure of the reflective layer. 图7A是图1的实施例的横截面,其中金属材料条带14沉积在垂直延伸的支撑件18上。 FIG 7A is a cross section of the embodiment of Figure 1, wherein the strip of metal material in the vertically extending support member 14 is deposited on 18. 在图7B中,可移动反射层14在系链(tether)32上仅在隅角处附接到支撑件。 In Figure 7B, the moveable reflective layer 14 in the tether (tethered) on only at the corners 32 is attached to supports. 在图7C中,可移动反射层14从可包括柔性金属的可变形层34悬垂下来。 In Figure 7C, the moveable reflective layer 14 is suspended from a flexible metal may comprise a deformable layer 34. 所述可变形层34直接或间接地连接到围绕可变形层34的周边的衬底20。 The deformable layer 34 can be directly or indirectly connected to the substrate 34 around the perimeter of the deformable layer 20. 这些连接在本文中称为支柱。 These connections are referred to herein as struts. 图7D中说明的实施例具有支柱插塞42,可变形层34搁在所述支柱插塞42上。 The embodiment illustrated in Figure 7D has support post plugs 42, the deformable layer 34 rests on the support post plugs 42. 如图7A-7C所示,可移动反射层14保持悬浮在腔上方,但可变形层34并不通过填充可变形层34与光学堆叠16之间的孔而形成所述支柱。 As shown in FIG 7A-7C, the movable reflective layer 14 remains suspended over the cavity, but the deformable layer 34 is not filled by the deformable layer 34 and the optical stack 16 is formed between the hole of the strut. 确切地说,支柱由用于形成支柱插塞42的平坦化材料形成。 Rather, the struts to form support post plugs 42 are formed of a planarization material. 图7E中说明的实施例是基于图7D中展示的实施例,但也可适于与图7A-7C中说明的实施例以及未图示的额外实施例的任一者一起发挥作用。 Described embodiment illustrated in Figure 7E is based on the illustrated embodiment of FIG. 7D, but may also be adapted to any one of the embodiments and additional embodiments not shown and described in FIGS. 7A-7C function together. 在图7E中所示的实施例中,已使用金属或其它导电材料的额外层来形成总线结构44。 In the embodiment illustrated in Figure 7E, to form a bus structure 44 has an extra layer of metal or other conductive material. 这允许信号沿着干涉仪调制器的背面进行路由,从而消除许多原本可能必须形成在衬底20上的电极。 This allows signal routing along the back of the interferometer modulators, eliminating a number of electrodes that may otherwise be formed on the substrate 20.

在例如图7中所示的那些实施例的实施例中,干涉仪调制器充当直接观看装置,其中从透明衬底20的前侧观看图像,所述侧与上面布置有调制器的一侧相对。 In those embodiments such as the embodiment shown in Figure 7, the interferometric modulators function as direct-view instrument apparatus, wherein images are viewed from the front side of the transparent substrate 20, disposed above the side opposite the side where the modulator . 在这些实施例中,反射层14在反射层的与衬底20相对的所述侧以光学方式遮蔽干涉仪调制器的一些部分,其包含可变形层34和总线结构44。 In these embodiments, the reflective layer 14 opposite the substrate side of the reflective layer 20 optically shields some portions of the interferometer modulator, including the deformable layer 34 and the bus structure 44. 这允许对遮蔽区域进行配置和操作而不会消极地影响图像质量。 This allows the shielded areas to be configured and operated upon without negatively affecting the image quality. 这种可分离的调制器结构允许选择用于调制器的机电方面和光学方面的结构设计和材料且使其彼此独立而发挥作用。 This separable modulator architecture allows the structural design and materials used for the electromechanical aspects and the optical aspects of the modulator and allowed to function independently of each other. 此外,图7C-7E中所示的实施例具有源自反射层14的光学性质与其机械性质脱离的额外益处,所述益处由可变形层34执行。 Further, the embodiment shown in FIG. 7C-7E have additional benefits derived from its mechanical properties the optical properties of the reflective layer 14 of detachment, which are carried out by the deformable layer 34. 这允许用于反射层14的结构设计和材料在光学性质方面得以最优化,且用于可变形层34的结构设计和材料在期望的机械性质方面得以最优化。 This allows the structural design and materials used for the reflective layer 14 be optimized in terms of optical properties, and the structural design for the deformable layer 34 and the material be optimized in terms of desirable mechanical properties.

干涉仪调制器显示器中的功率消耗参看图1,将了解,干涉仪调制器具有使其在电性方面表现得类似于电容器的结构特性。 Interferometer modulator display power consumption in reference to Figure 1, it will be appreciated, the interferometer modulator having a characteristic structure in electrical terms so behave like a capacitor. 图1的干涉仪调制器两者均包含由不同间隙分离的平行导电板。 Interferometer modulator of FIG. 1 comprises both separated by a gap different parallel conductive plates. 大体上来说,两个平行导电板可形成具有由下式给定的电容的电容器:C=ϵAD]]>其中C是电容,ε是两个导电板之间的材料的电容率,A是板的面积,且D是板之间的距离。 Generally speaking, two parallel conductive plates may have a capacitor formed by the capacitance given by: C = & epsiv; AD]]> where C is the capacitance, [epsilon] is the permittivity of the material between the two conductive plates, A It is the area of ​​the plate, and D is the distance between the plates. 在未激活的干涉仪调制器中,导电镜14a由间隙与导体16a分离,所述间隙大于被激活的干涉仪调制器中导电镜14b与导体16b之间的间隙。 Unactivated interferometer modulator, the conductive mirror separated by a gap 14a and a conductor 16a, the gap is larger than the gap between the conductive mirror 14b and conductor 16b is activated interferometer modulator. 因此,被激活的干涉仪调制器的电容大于未激活的干涉仪调制器。 Thus, the interferometer is activated is greater than the capacitance of the modulator is not activated interferometer modulator.

在一个实施例中,干涉仪调制器显示器中功率消耗的显著来源是来自对被激活和未激活的干涉仪调制器进行电容充电。 In one embodiment, a significant source of the interferometer modulator display of power consumption from the active and inactive interferometer modulator capacitive charging. 因为被激活与未激活的干涉仪调制器的电容不同,所以干涉仪调制器中的功率消耗将依据在给定帧中所显示的图像而变化。 Since the unactivated is activated interferometer modulator different capacitance, the interferometer modulator will vary depending on the power consumption in a given frame image as displayed. 如下文进一步论述,功率消耗的帧内容差异是由于被激活和未激活的干涉仪调制器的数目以及图像内各个像素的位置造成的。 As discussed further below, the contents of the frame difference in power consumption because the number and the position of each pixel within the image is active and inactive interferometer modulator caused.

在一个实施例中,由处于接通状态的像素所消耗的功率与由处于断开状态的像素所消耗的功率分离地进行确定。 In one embodiment, the pixel power and the power consumed in the OFF state of the pixel in an ON state by being consumed separately determined. 在一个实施例中,通过测量由单个接通或断开像素所消耗的功率来确定由接通或断开像素所消耗的功率。 In one embodiment, it is determined by measuring the power is turned on or turned on or off by the power consumed by pixels pixels consumed by a single disconnection. 在另一实施例中,测量整行或列的接通或断开像素所消耗的功率以便确定单个接通或断开像素所消耗的平均功率。 In another embodiment, the entire row or measurement on or off the power consumed by the column of pixels in order to determine the average power of a single pixel is turned on or turned off consumed. 在一个实施例中,测量由显示器中接通或断开的所有像素所消耗的功率以便确定单个接通或断开像素所消耗的平均功率。 All of the power consumed by the pixels in one embodiment, the measurement by the display is turned on or off in order to determine the average power of a single pixel is turned on or turned off consumed. 在一个实施例中,通过将电压阶跃(voltage step)施加到像素并测量所产生的电流来测量一个或一个以上像素所消耗的功率。 In one embodiment, by a voltage step (voltage step) is applied to the pixels and measuring the resulting current measured power of one or more pixels consumed. 在一个实施例中,在一时段内测量所产生的电流。 In one embodiment, a current measuring period generated. 根据以下等式求所述电流的积分并乘以电压阶跃的值将得到所消耗的功率:P=Vs∫0Ti(t)dt]]>其中Vs是电压阶跃的量值(假定恒定电压),i(t)是作为时间的函数的所产生的电流,且T是确定功率所持续的时段。 The value of the integral equation of the required voltage step and multiplied by the current will be consumed power: P = Vs & Integral; 0Ti (t) dt]]> where Vs is the voltage step magnitude (assuming a constant voltage ), i (t) is a current as a function of time generated, and T is a period duration determined power. 在干涉仪调制器显示器的一些实施例中,Vs是2Vbias。 In some embodiments, the interferometer modulator display in, Vs is 2Vbias. 如下文更详细描述,对干涉仪调制器显示器中的功率消耗最显著的贡献是列线上的电压切换,其通常是从+Vbias到-Vbias的变换且反之亦然。 As described in greater detail, the interferometer modulator display of power consumption in the most significant contribution is the column line voltage switching, which is typically from + Vbias to -Vbias conversion and vice versa. 因此,使用2Vbias的测试电压阶跃将提供暴露于列线上的典型电压切换的像素所消耗的功率的量度。 Thus, using the test voltage step 2Vbias will provide a measure of the power of the pixels are exposed to a typical voltage of column line switching consumed.

在另一实施例中,假定像素表现得如同理想的电容器。 In another embodiment, assuming the pixel behaves as an ideal capacitor. 因此,两个或两个以上电流值可在不同时间获得且接着与对理想电容器的预期响应保持一致以确定像素所消耗的电容和/或功率。 Accordingly, the current value of two or more can be obtained at different times and then the expected response of an ideal capacitor to determine a consistent capacitance and / or the power consumed by pixels. 举例来说,在一个实施例中,在施加电压阶跃之后测量电流峰值,且接着在一经过的时间量之后记录第二电流值。 For example, in one embodiment, the voltage step is applied after the current peak measurement, and then a second current value recorded after an amount of time elapsed. 图8中描绘施加电压阶跃之后观察到的电流响应。 Current response observed after application of a voltage step depicted in Figure 8. 在一些实施例中,使用所述两个或两个以上电流测量值来确定像素的松弛时间,接着可使用所述松弛时间来确定电容和/或功率。 In some embodiments, the use of two or more current measurements to determine the relaxation time of the pixel, the relaxation time may then be used to determine the capacitance and / or power. 给定电压阶跃之后的电流峰值和松弛时间,可从下式中确定功率:P=Vsipeak∫0Te-t/τdt=Vsipeakτ(1-eT/τ)]]>其中是Vs是电压阶跃的量值,ipeak是电流阶跃之后的峰值电流的值,T是需要功率所持续的时段,且τ是松弛时间。 A current peak and the relaxation time after a given voltage steps, from the equation determining the power: P = Vsipeak & Integral; 0Te-t / & tau; dt = Vsipeak & tau; (1-eT / & tau;)]]> where is Vs is the voltage step magnitude, IPEAK is the peak value of the current after the current step, T is the period of continuous power required, and τ is the relaxation time. 所属领域的技术人员将了解,可通过分别施加任何数目的电压或电流刺激且接着测量所产生的电流或电压来确定功率和电容值。 Those skilled in the art will appreciate, by applying any number of voltage or current stimulation and then measuring the generated current or voltage to determine power and capacitance values, respectively.

在一个实施例中,可使用电流读出放大器来确定由于施加电压刺激而产生的电流。 In one embodiment, the current sense amplifier may be used to determine the current application of a voltage generated stimulation. 图9中描绘用于实施电流读出放大器的电路的实例。 In Examples 9 depicts a circuit embodiment of the current sense amplifier. 在节点100处提供电压刺激。 Stimulating voltage provided at node 100. 电压刺激将电压提供到线选择器102,所述线选择器102耦合到处于被测试的显示器104上的一个或一个以上线。 Stimulation voltage to the voltage line selector 102, the line selector 102 is coupled to be tested in one or more of a display 104 lines. 显示器104上的一个或一个以上其它线耦合到线选择器106,所述线选择器106连接到地面。 One or more other lines on the display 104 is coupled to a line selector 106, the line selector 106 is connected to ground. 在一些实施例中,线选择器102耦合到显示器104中一个或一个以上列线,且线选择器106耦合到显示器104中一个或一个以上行线。 In some embodiments, the line selector 102 is coupled to a display 104, one or more column lines, and the line selector 106 is coupled to a display 104 in one or more row lines. 在一个实施例中,显示器104是例如图5A、6A和6B中所描绘的显示器阵列30。 In one embodiment, the display 104, for example, in FIG. 5A, 6A and 6B, the display array 30 as depicted. 线选择器102和106可提供选择性地耦合到一个或一个以上列和行的能力。 Line selector 102 and 106 may be selectively coupled to provide one or more rows and columns capabilities. 或者,线选择器102和106可硬连线到一组一个或一个以上列和行。 Alternatively, the line selector 102 and 106 may be hardwired to a set of one or more columns and rows. 在一个实施例中,线选择器102和106允许将电压刺激提供到期望的个别像素、期望的列、期望的行,或数组列和/或行。 In one embodiment, the line selector 102 and 106 allows the voltage to the individual pixels of stimuli desired, the desired column, the desired row or column of the array and / or rows. 在一个实施例中,线选择器102和106分别耦合到所有列和行使得整个显示器被成组驱动(例如,以相同电压刺激驱动所有像素)。 In one embodiment, the line selector 102 and 106 are coupled to all rows and columns so that the entire display is driven in groups (e.g., at the same driving voltage to stimulate all the pixels). 通过使用连接越过读出电阻器110的放大器108来检测对于电压刺激的电流响应。 By using a connection over the read amplifier 108 to the resistor 110 for detecting a voltage in response to current stimuli. 接着在输出节点112处提供电流。 Then providing a current at the output node 112.

在替代实施例中,可将电流读出放大器放置在线选择器102和106与显示器之间。 In an alternative embodiment, the current sense amplifier may be disposed between the display line 102 and the selector 106. 在此实施例中,电流读出放大器可同时耦合到所有行和/或列。 Embodiment, the current sense amplifier may be coupled simultaneously to all rows and / or columns in this embodiment. 然而,电流将仅流过由线选择器102和106选定的行和/或列。 However, only current will flow through the line selected by the selector 102 and 106 rows and / or columns. 在一个实施例中,在线选择器102和106与显示器之间提供多个电流读出放大器电路。 In one embodiment, the selector 102 and the line 106 between the display and providing a plurality of current sense amplifier circuit. 因此,举例来说,可为每一行和/或列提供电流读出放大器。 Thus, for example, may be provided for each current row and / or column sense amplifiers.

在显示器包含具有不同颜色的子像素的实施例中,可针对每一颜色子像素的接通和断开状态确定电容和/或功率值。 In the embodiment comprising a display sub-pixels having different colors, the capacitance may be determined and / or power values ​​for on and off states of each color subpixel. 举例来说,在一些干涉仪调制器显示器中,每一颜色子像素的干涉仪调制器的数目将不同于其它颜色子像素以便提供期望的色平衡。 For example, in some interferometer modulator display, the number of interferometer modulator for each color sub-pixel to sub-pixel is different from the other colors in order to provide a desired color balance. 因此,由于导电表面的面积增加,所以每一颜色子像素将与处于相同状态的其它颜色子像素具有不同的电容值。 Other color sub Accordingly, due to the increased area of ​​the conductive surface, so each color sub-pixel in the same state with the pixels have different capacitance values. 此外,未激活干涉仪调制器中的间隙对于不同颜色将会不同,从而产生不同的电容值。 Further, a gap not actuate the interferometric modulator device will be different for different colors, resulting in different capacitance values.

在一个实施例中,在确定一个或一个以上像素的电容和/或功率消耗之前,确定像素的状态使得知道正探测的是什么状态。 In one embodiment, prior to the determination of one or more pixel capacitance and / or power consumption, the state of the pixel is determined such that a positive detection is know what state. 因此,如图10中的流程图中所描绘,确定一个或一个以上像素的功率和/或电容的一个实施例包含确定像素处于接通还是断开(方框150),将电压刺激施加到像素(方框152),和接着测量所产生的电流(方框154)。 Accordingly, the flowchart in FIG. 10 depicted, a determined embodiment the one or more pixels of a power and / or capacitance in the embodiment comprises determining a pixel on or off (block 150), the stimulation voltage applied to the pixel (block 152), and then the current (block 154) measurements generated. 视特定实施例而定,可在图10中描述的那些步骤中添加步骤,或可去除一些步骤。 Depending on the particular embodiment given, those steps may be described in FIG. 10 addition steps, or some steps may be removed. 另外,可依据应用来重新布置步骤的次序。 Further, the order may be rearranged according to the application step. 在一个实施例中,电压刺激是电压阶跃。 In one embodiment, the stimulus is a voltage of the voltage step. 在各种实施例中,通过视觉上观察像素,用光电检测器或分光仪检测来自像素的光,或测量像素的光学状态来确定像素是接通还是断开。 In various embodiments, the pixel was observed visually by using a photoelectron spectrometer detector or light detecting optical state, or measurement of the pixel from the pixel determines the pixel is on or off. 在一个实施例中,像素包含干涉仪调制器,且通过施加一电压或已知的一系列电压以将干涉仪调制器置于被激活或未激活状态来执行确定像素是接通还是断开。 In one embodiment, the interferometer modulator comprising a pixel, and by applying a voltage or voltage range known to be placed in the interferometer modulator performing active or inactive state determines that the pixel is on or off.

建模显示器中的功率消耗在一个实施例中,通过使每一像素表现为电容器来建模显示器中的功率消耗,其中接通的像素(例如,未激活的干涉仪调制器)和断开的像素(例如,被激活的干涉仪调制器)具有不同的电容值。 Modeling the power consumption in the display in one embodiment, by having each pixel capacitor to model the performance of the power consumption of the display, the pixels (e.g., inactive interferometer modulator) which is turned on and off pixels (e.g., activated interferometer modulators) have different capacitance values. 可如上文论述或通过所属领域的技术人员已知的任何适合的方法来确定接通和断开的像素的电容值。 As discussed above can be determined or is turned off and the capacitance value of a pixel by any suitable method known to those of ordinary skill in the art. 接着可提供含有每一像素的状态信息的图像,且基于每一像素的电容和施加于像素的电压驱动方案来确定对于一个或一个以上帧在图像显示期间的功率消耗的估计值。 Then the image containing the status information may be provided for each pixel, and determining an estimated value of the power consumption for a period of one or more image display frames based on each pixel capacitance and voltage is applied to the pixel driving scheme.

如上文参看图4和5所论述,通过改变施加到显示器的行和列两者的电压将一些干涉仪调制器显示器中的像素置于被激活或未激活状态。 As described above with reference to FIGS. 4 and 5 discussed above, both the voltages applied to the row and column display some interferometer modulator display of the pixel in the active or inactive status is changing. 如图5B中所描绘,通过视需要将每一列电压设定为+Vbias或-Vbias且接着将电压脉冲发送到待更新的行来逐行更新像素。 As depicted in Figure 5B, each column required voltage is set to + Vbias, or -Vbias, and then sends the voltage pulse to the row to be updated by the updated pixel row view. 在更新给定帧中所有行时,任何给定列上的电压切换可发生多次。 Updating all rows in a given frame, any multiple voltage switching may occur on a given column. 与此对比,在帧更新期间,给定帧中每一行上的电压切换发生得较不频繁。 In contrast, during a frame update, the voltage on each line in a given frame to give a handover occurs less frequently. 因此,由于对干涉仪调制器进行电容充电而造成的功率消耗主要是由于列引线上的电压切换而发生的。 Accordingly, since the interferometer modulator capacitive charge caused by the power consumption is mainly due to the voltage on the column leads handover occurs. 因此,在一个实施例中,忽略由于到达行引线的电压脉冲而造成的功率消耗,且基于+Vbias或-Vbias之间的连续电压切换来确定功率,且反之在帧刷新期间在列引线上亦然。 Thus, in one embodiment, the power consumption is ignored since the lead line reaches a voltage pulse caused, and based on switching between the continuous voltage + Vbias, or -Vbias determine the power, and vice versa in the column during the refresh also lead frame However. 在一些实施例中,并非所有像素均需要进行刷新。 In some embodiments, not all the pixels need to be refreshed. 举例来说,如果某些行不含有任何变化的像素,那么帧刷新期间不需要将电压脉冲发送到那些行且可能不需要在一些列上进行电压切换,藉此减少所述帧期间所消耗的功率。 For example, if the pixel rows that do not contain any changes, then the need to send the frame during the refresh voltage pulse to the row that is not required and may in some column voltage switching, thereby reducing the consumption of the frame period power.

大体上来说,可从下式确定给定列(例如,第j列)上的电压切换所消耗的功率:Pj=Σi=1Ns12TCijVS2]]>其中i识别特定行,j识别特定列,Ns是帧期间列线上电压切换的数目,T是帧显示的时段,Cij是第i电压切换期间列的电容,且Vs是电压切换的量值。 Power voltage switching consumption generally speaking, may be given column (e.g., j-th column) from the formula is determined on: Pj = & Sigma; i = 1Ns12TCijVS2]]> where i identifying a specific row, j identifies the particular column, Ns of during the frame number of the column line voltage is switched, T is the frame display period, Cij is a column voltage during the i-th switched capacitor, and Vs is the switching voltage magnitude. 可从下式确定电容Cij:Cij=Nup ijCup+Ndown ijCdown其中Nup ij是第j列中的在第i电压切换期间处于上升状态的像素的数目,Ndown ij是在第i电压切换期间处于下降状态的像素的数目,Cup是处于上升状态的像素的电容,且Cdown是处于下降状态的像素的电容。 From the following equation to determine the capacitance Cij: ijCdown Cij = Nup ijCup + Ndown wherein Nup ij is the number of pixels during the i-th voltage switching is on the rise in the j-th column, Ndown ij is in a lowered state during the i-th voltage switching capacitive pixel capacitive pixel number of pixels, Cup is in the rising state, and is in a lowered state Cdown. Cup和Cdown可通过例如上文描述的电压阶跃方法的任何适合的方法来确定,或基于像素中材料的性质来计算。 Cup and Cdown may be determined by any suitable method, for example, a voltage step of the method described above, or calculated based on the material properties of the pixels. 如先前说明,在一些实施例中,Vs将为2Vbias(即,从+Vbias到-Vbias(或反之亦然)的电压切换的量值)。 As previously described, in some embodiments, Vs will 2Vbias (i.e., from + Vbias to -Vbias (or vice versa) the magnitude of the voltage switching).

在一些实施例中,尤其是图像在帧之间不显著变化的实施例中,可通过下式来约计列的功率:Pj=12TCjVS2NSj]]>其中Cj是第j列的电容,且NSj是所述帧期间第j列上的电压切换事件的数目。 In some embodiments, the particular image is not significant between the frames the embodiment variations, by the following equation to approximate column Power: Pj = 12TCjVS2NSj]]> where Cj is the j-th column of the capacitance, and NSj is the the number of voltage switching event on the j-th column of said frame period. 在这一表达式中,第j列的电容由下式给定:Cj=Nup jCup+Ndown jCdown其中假定列的内容(即,如Nup j和Ndown j所确定)从一个切换事件到下一切换事件不会变化。 In this expression, the j-th column is given by the capacitance: Cj = Nup jCup + Ndown jCdown assuming that contents of the column (i.e., such as Nup and Ndown j j determined) to switch from one to the next switching event event does not change.

一个帧期间整个显示器所消耗的功率可通过对所有列求和来确定:Pdisplay=Σj=1NcolPj]]>其中Ncol是显示器中列的数目。 A consumed power of the entire display frame period can be determined by summing all columns: Pdisplay = & Sigma; j = 1NcolPj]]> where Ncol is the number of columns in the display.

将了解,任何给定列所消耗的功率很大程度上取决于列的内容(例如,如Nup j和Ndown j所确定)以及影响列上所需的电压切换的数目(例如,NSj)的图像的其它部分的内容。 It will be appreciated that any given column consumed power depends largely on the contents of a column (e.g., such as Nup j is determined and Ndown j) and the number of voltage switching required to impact on a column (e.g., NSJ) Image the contents of the other part. 因此,在一个实施例中,提供估计显示器(例如,干涉仪调制器显示器)所消耗的功率的计算机实施的方法,其中所述方法包含将一图像或一系列图像提供作为输入,和接着确定一个或一个以上帧期间显示器所消耗的功率。 Method Thus, in one embodiment, provide an estimate of a display (e.g., an interferometric modulator display device) of the power consumed by the computer-implemented, wherein the method comprises providing an image or series of images as input, and then determines a one or more frames during a power consumed by the display. 在一些实施例中,用于确定功率的算法利用电容器来建模显示器中的像素和/或子像素,其中接通的像素和/或子像素被分配与断开的像素的电容值不同的电容值。 Different capacitance values, in some embodiments, an algorithm for determining a power by the capacitor modeled pixels in the display and / or sub-pixels, wherein the pixel is turned on and / or sub-pixel is assigned pixel capacitance and off value. 在一些实施例中,所述算法计算显示器中每一列所消耗的功率。 In some embodiments, the display algorithm calculates power consumed in each column. 在一些实施例中,所述算法计算列上每一电压切换期间每一列所消耗的功率。 In some embodiments, the algorithm calculates the power consumed by the column each column during each voltage switching. 在一些实施例中,确定在帧刷新期间小于整个图像被更新时的功率。 In some embodiments, the frame refresh period is determined smaller than the power of the entire image is updated. 在一些实施例中,所述算法包含用于读取和处理图像或一系列图像的指令。 In some embodiments, the algorithm comprising instructions for reading and processing an image or series of images.

实例为了证明图像内容对功率消耗的影响,预测160像素×160像素的单色干涉仪调制器显示器上所显示的各种图像的功率消耗。 Examples In order to demonstrate the impact on the power consumption of the image content, the predicted power consumption of the various images of 160 pixels × 160 pixels monochrome interferometer modulator displayed on the display. 将明亮状态(未激活)像素建模成具有0.71pF电容的电容器。 The bright state (inactive) pixels 0.71pF capacitance modeled as capacitor. 将黑暗状态(被激活)像素建模成具有10.8pF电容的电容器。 The dark state (activated) 10.8pF pixel capacitance modeled as capacitor. 所使用的帧速率是每帧1s。 Frame rate is used for each frame 1s. Vbias为5伏(例如,列上的切换电压为10伏)。 Vbias of 5 volts (e.g., column switching voltage is 10 volts).

实例1-4×4棋盘图像如图13A中所描绘,建模4×4棋盘图像,其中每40像素×40像素区域处于相反状态(即,明亮或黑暗)。 Examples 1-4 × 4 checkerboard image as depicted in FIG. 13A, modeled 4 × 4 checkerboard image, wherein each pixel region 40 × 40 pixels in the opposite state (i.e., bright or dark). 举例来说,正方形200中列1与列40之间和行1与行40之间的所有像素均处于明亮状态。 For example, between column 40 and row 1 and column 200 all the pixels between the square and the row 40 are in a bright state. 与此对比,正方形202中列1与列40之间和行41与行80之间的所有像素均处于黑暗状态。 In contrast, all 80 pixels between the square columns 202 and between columns 40 and row 1 to row 41 are in a dark state. 图像从帧到帧呈现为相同的。 Rendered image from frame to frame are the same. 为了在每一帧中刷新所有行时维持显示器上的图像,可使用图13B中描绘的电压驱动方案。 To maintain image refresh all rows on the display, the drive voltage scheme may be used as depicted in FIG. 13B in each frame. 在帧时间212的写入时间210部分期间,将+ΔV脉冲连续施加到显示器中每一行线。 During the write time 212 of the time frame portion 210, the continuous pulse + ΔV is applied to each row line display. 在每一脉冲期间,可将每一列上的电压设定为+Vbias或-Vbias,使得施加到每一像素的净电压导致如下像素电压,所述像素电压使像素被迫激活(例如,-Vbias-ΔV)、解除激活(例如,+Vbias-ΔV≈0),或保持在先前状态(例如,行电压为0使得所述电压在滞后存储窗口内为+Vbias或-Vbias)。 During each pulse, the voltage may be set on each column to + Vbias, or -Vbias, so that the net voltage applied to each pixel as a pixel voltage causes the pixel voltage of the pixel forced activation (e.g., -Vbias [Delta] V), deactivate (e.g., + Vbias-ΔV≈0), or remain in the previous state (e.g., 0 such that the line voltage is within the hysteresis voltage + Vbias store window or -Vbias). 为了维持图13A中所描绘的图案,在对行1-40和81-120施加脉冲的同时将列1-40和81-120设定为+Vbias且将列41-80和121-160设定为-Vbias,且在对行41-80和121-160施加脉冲的同时将列1-40和81-120设定为-Vbias且将列41-80和121-160设定为+Vbias。 FIG. 13A in order to maintain the pattern drawn, while applying a pulse to the column lines 1-40 and 1-40 and 81-120 81-120 set to + Vbias columns 41-80 and 121-160 and the setting to -Vbias, and at the same time a pulse is applied to the column lines 41-80 and 121-160 81-120 1-40 and set to -Vbias and the columns 41-80 and 121-160 is set to + Vbias. 如图13B中所描绘,每一列线在每一帧期间经历三次量值为2Vbias的电压转换。 As depicted in FIG. 13B, each of the column lines during each frame is subjected to three times the magnitude of the voltage converter 2Vbias.

如图13A中可以看出,每一列的像素的一半处于被激活状态且一半处于未激活状态。 As it can be seen in FIG. 13A, one half of each column of pixels in the active state and the inactive half. 因此,每一列的电容相同且计算为C=80像素×0.71pF+80像素×10.8pF=921pF。 Thus, the capacitance of the same and each column is calculated as C = 80 pixels × 0.71pF + 80 pixels × 10.8pF = 921pF. 如上文所说明,每一列的电压切换的数目为三(即,Ns=3),且电压切换的量值为10V。 As explained above, the number of voltage switching of each column is three (i.e., Ns = 3), and the magnitude of the switching voltage is 10V. 因此,使用上述公式,一个帧期间所消耗的功率计算为22.1μW。 Thus, using the above equation, a frame power consumed during the calculation of 22.1μW.

实例2-16×16棋盘图像如图14A中所描绘,建模16×16棋盘图像,其中每10像素×10像素区域处于相反状态(即,明亮或黑暗)。 Examples 2-16 × 16 checkerboard image depicted in FIG. 14A, modeling board 16 × 16 image, wherein each pixel area 10 × 10 pixels are in the opposite state (i.e., bright or dark). 图像从帧到帧呈现为相同的。 Rendered image from frame to frame are the same. 为了在每一帧中刷新所有行时维持显示器上的图像,可使用图14B中所描绘的电压驱动方案。 To maintain image refresh all rows on the display, the driving voltage may be used in the embodiment depicted in FIG. 14B in each frame. 在帧时间212的写入时间210部分期间,将+ΔV脉冲连续施加到显示器中每一行线。 During the write time 212 of the time frame portion 210, the continuous pulse + ΔV is applied to each row line display. 在每一脉冲期间,可将每一列上的电压设定为+Vbias或-Vbias,使得施加到每一像素的净电压导致如下像素电压,所述像素电压使像素被迫激活(例如,-Vbias-ΔV)、解除激活(例如,+Vbias-ΔV≈0),或保持在先前状态(例如,行电压为0使得所述电压在滞后存储窗口内为+Vbias或-Vbias)。 During each pulse, the voltage may be set on each column to + Vbias, or -Vbias, so that the net voltage applied to each pixel as a pixel voltage causes the pixel voltage of the pixel forced activation (e.g., -Vbias [Delta] V), deactivate (e.g., + Vbias-ΔV≈0), or remain in the previous state (e.g., 0 such that the line voltage is within the hysteresis voltage + Vbias store window or -Vbias). 为了维持图14A中所描绘的图案,在任何给定时间列1-10、21-30、41-50、61-70、81-90、101-110、121-130、141-150和161-170具有与列11-20、31-40、51-60、71-80、91-100、111-120、131-140和151-160相反的极性的情况下,在写入时间210期间将列电压切换15次。 FIG. 14A in order to maintain the pattern drawn, at any given time and columns 1-10,21-30,41-50,61-70,81-90,101-110,121-130,141-150 161- 170 and having a lower column 11-20,31-40,51-60,71-80,91-100,111-120,131-140 151-160 polarity opposite case, during the write time 210 voltage switching column 15 times. 如图14B中所描绘,每一列线在每一帧期间经历15次量值为2Vbias的电压转换。 As depicted in Figure 14B, each column line is subjected to 15 times the magnitude of the voltage conversion 2Vbias during each frame.

如图14A中可以看出,每一列的像素的一半处于被激活状态且一半处于未激活状态。 As it can be seen in FIG. 14A, one half of each column of pixels in the active state and the inactive half. 因此,每一列的电容与实例1中所计算的相同(C=80像素×0.71pF+80像素×10.8pF=921pF)。 Thus, the same capacitance of each column in Example 1 was calculated (C = 80 pixels × 0.71pF + 80 pixels × 10.8pF = 921pF). 如上文所说明,每一列的电压切换的数目为15(即,Ns=15),且电压切换的量值为10V。 As explained above, the number of voltage switching of each column 15 (i.e., Ns = 15), and the magnitude of the switching voltage is 10V. 因此,使用上述公式,一个帧期间所消耗的功率计算为110.5μW。 Thus, using the above equation, a frame period consumed power is calculated as 110.5μW. 这一结果证明帧期间所消耗的功率很大程度上取决于图像内容。 These results demonstrate the power consumed during the frame largely depends on the image content. 举例来说,尽管实例1与2中每一列的电容相同(即,存在相同数目的明亮和黑暗像素),但消耗的功率的数量级不同。 For example, although the same as Example 1 and the capacitor 2 in each column (i.e., the presence of the same number of bright and dark pixels), but a different number of stages of the power consumed.

实例3-部分帧更新对将作为实例1的4×4棋盘图像更新为图15A中所描绘的新图像进行建模。 Example 3 part of the frame will be updated to a new image depicted in FIG. 15A as 4 × 4 checkerboard image updating Example 1 Modeling. 新帧中的差异是,由列81到120和行41到80界定的正方形中的像素从黑暗状态(被激活)变为明亮状态(未激活)。 New frame difference is from 81 to 120 and the column lines to define 80 square pixel (activated) becomes a bright state (inactive) from a dark state 41. 不同于通过将电压脉冲发送到所有行线来刷新整个图像,将脉冲连续发送到仅那些含有改变的像素的行(即,行8到120)。 Unlike to refresh the whole picture by sending a voltage pulse to all the row lines, continuously transmits a pulse to the row containing only those pixels changed (i.e., rows 8-120). 因为帧时间212期间仅将脉冲施加到40行,所以写入时间210比刷新整个显示器时短。 Since only a pulse is applied to the line 40 during the time frame 212, the write time 210 than the short refresh the entire display. 图15B中描绘从原始帧产生新帧所需的列电压。 FIG. 15B depicts a new frame produce the desired voltage from the original frame sequence. 所有列需要一次电压转换。 All columns need a voltage converter. 列1到120的极性与列121-160的极性相反。 1-120 polar column and the column opposite to the polarity 121-160.

列1-40和81-160的电容与实例1和2中列的电容相同(C=80像素×0.71pF+80像素×10.8pF=921pF)。 Columns 1-40 and 81-160 of the capacitor of Example 1 and the same column of the second capacitor (C = 80 pixels × 0.71pF + 80 pixels × 10.8pF = 921pF). 与此对比,通过C=120像素×0.71pF+40像素+10.8pF=517.2pF(即,120个像素处于明亮状态(未激活)且40个像素处于黑暗状态(被激活))来确定列41-80的电容。 In contrast, pixel by C = 120 pixels × 0.71pF + 40 + 10.8pF = 517.2pF (i.e., 120 pixels in the bright state (inactive) and 40 pixels in a dark state (to be activated)) to determine the columns 41 -80 capacitance. 如上文所说明,每一列的电压切换的数目为一次(即,Ns=1),且电压切换的量值为10V。 As explained above, the number of voltage switching of each column is one (i.e., Ns = 1), and the magnitude of the switching voltage is 10V. 因此,使用上述公式,具有所指示的部分更新的一个帧期间所消耗的功率计算为6.6μW,其显著小于实例1中所计算的对于总体帧刷新的22.1μW。 Thus, the power consumed during a frame part using the formula above, having the indicated updating is calculated as 6.6μW, which is significantly less than for the whole frame refresh 22.1μW computed in Example 1. 因此,可使用建模方法来确定某些图像内容转换期间部分显示器刷新的功率节省。 Thus, modeling can be used to determine the portion of the display image content conversion refresh during certain power savings.

尽管已参照实施例和实例描述了本发明,但应了解,可在不脱离本发明精神的情况下作出许多各种修改。 While the present invention has been described with reference to embodiments and examples, it will be appreciated that many various modifications may be made without departing from the spirit of the invention. 因此本发明仅由所附权利要求书限定。 Thus, the present invention is limited only by the appended claims.
