摘要： A cyclic rail-stabilized method of driving an electrophoretic display device (1), wherein a substantially dc-balanced driving waveform is used to effect the various required optical transitions. The driving waveform consists of a plurality of picture potential differences (20), which cause the charged particles (6) of the electrophoretic device (1) to cyclically between extreme optical positions in a single optical path, irrespective of the image sequence required to be displayed, i.e. in order to display each grey scale, it is necessary for the particles (6) to first pass through one of the extreme optical states. In order to minimise the effects of dwell time on the image quality and minimise, or even eliminate, the need to consider image history, shaking pulses (10) are generated immediately prior to each picture potential difference (20).
摘要翻译：一种驱动电泳显示装置（1）的循环轨道稳定方法，其中使用基本上直流平衡的驱动波形来实现各种所需的光学转换。驱动波形由多个图象电位差（20）组成，这使得电泳装置（1）的带电粒子（6）在单个光路中在极端光学位置之间循环地进行，而不管所需的图像序列如何显示，即为了显示每个灰度级，粒子（6）必须首先通过极端光学状态之一。为了最小化驻留时间对图像质量的影响并且最小化或甚至消除考虑图像历史的需要，在每个图像电位差（20）之前立即产生抖动脉冲（10）。

摘要： An electrophoretic display (1) comprising an electrophoretic medium (5) comprising a plurality of negatively charged black particles (6) and a plurality of positively charged white particles (6) in fluid. The average dc value of the drive voltages is arranged to be non-zero, so as to maximise brightness or contrast ratio of the displayed image, as required. If the average dc value of the drive voltages has a positive polarity, such that a small positive voltage is applied to the pixel electrode (3), although the white level may be less bright, the black level becomes darker, thereby increasing the contrast ratio during the driving sequence, which is obviously advantageous if the contrast ratio is the most important display parameter. If, on the other hand, maintaining or increasing a maximum brightness level is of key importance, then a drive sequence where the average dc value of all drive waveforms has a negative polarity is applied, so as to apply a small, controlled negative voltage to the pixel electrode (3). In this case, although the black level may become less dark, the white level becomes significantly brighter, such that the brightness is increased during the driving sequence, which is obviously advantageous if brightness is the most important display parameter.
摘要翻译：一种电泳显示器（1），包括电泳介质（5），其包括多个带负电荷的黑色颗粒（6）和多个带正电荷的白色颗粒（6）。驱动电压的平均直流值被布置为非零，以便根据需要使显示图像的亮度或对比度最大化。如果驱动电压的平均直流值具有正极性，使得对像素电极（3）施加小的正电压，尽管白电平可能不太亮，但是黑电平变得更暗，从而增加对比度在驱动顺序期间，如果对比度是最重要的显示参数，这显然是有利的。另一方面，如果保持或增加最大亮度水平是至关重要的，则施加所有驱动波形的平均直流值为负极性的驱动序列，以便将小的受控负电压施加到像素电极（3）。在这种情况下，尽管黑色电平可能变得较暗，但白色电平变得明显更亮，使得在驱动序列期间亮度增加，如果亮度是最重要的显示参数，这显然是有利的。

摘要： An electrophoretic display device (1) comprising one pixel (10) with an electrophoretic medium (13), electrodes (6, 7), as well as drive means (4) by which the pixels can be brought into different optical states. Some time (thold) after the application of an addressing pulse (Paddress) for setting the brightness level (Rw, Rb) of a pixel (10), a restore pulse voltage (Prestore) is applied between the electrodes (6,6′,7) for restoring the brightness level of a pixel to the set level (Rw, Rb). The restore pulse may be a set of consecutive pulses to bring the drifted brightness level even more smoothly (i.e. less perceivably) back to the original brightness level.

摘要： A touch sensitive matrix display senses touch input during a sense period (TS) in a separate sense area (A1) which is selected to be non-overlapping with a display area (A2) in which information is displayed dependent on the touch position which is sensed in the sense area (A1). During the sense period (TS), the sense area (A1) is not addressed. The non-address period of time (TR) occurring between two successive sense area addressing periods (TA2) of the sense area (A1) lasts at least as long as, but preferably substantially longer than, the display area address period (TA1,i) required to address the complete display area (A2). The data displayed in the sense area (A1) is refreshed by addressing the sense area (A1) during the sense area address periods (TA2) in-between the sense periods (TS). The data displayed in the sense area (A1) will not be disturbed by the sensing and will be present between two successive sense area addressing periods (TA2, TA2′) because the pixels 10 of the matrix display have an optical state which, when not addressed, is maintained longer than the non-address period (TR).
