    摘要： The electrophoretic display panel (1) for displaying a picture corresponding to image information has drive means (100) which are able to control for each picture element (2) the potentials, thereby being able to change the position of the particles (6) based on the image information. Furthermore, the display panel (1) has monitoring means (101) which are able to generate for each picture element (2) actual position information indicative for the actual position of the particles (6), and control means (103) which are able to control for each picture element (2) the drive means (100) in dependence of the actual position information and the image information to reduce a difference between the position of the particles (6) and the position off the particles (6) corresponding to the image information. For the display panel (1) to be able to provide a picture of relatively high quality even at relatively low or nonuniform intensities of the ambient light, the monitoring means (101) comprise electrical means (102) which are able to generate for each picture element (2) the actual position information based on an electrical property of the respective picture element (2).

    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： 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).

    摘要： A touch sensitive matrix display senses touch input in sense periods (SP) which are selected to occur non-concurrently with data (DA) written to the pixels (10) of the matrix display during the addressing period (AP). As now, no data (DA) is written to the display while the sensing is performed during the sense periods (SP), the sensing will be less complicated. The sense periods (SP) are selected to occur in-between successive addressing periods (AP) because the display has pixels (10) of which the optical state is maintained substantially longer than the addressing period (AP) lasts. Such a hold period (HP) which lasts substantially longer than the addressing period (AP) is for example available in bistable displays such as electrophoretic displays.

    摘要翻译： 感测矩阵显示器感测感测周期（SP）中的触摸输入，其在寻址周期（AP）期间与写入矩阵显示器的像素（10）的数据（DA）非同时发生。 现在，在感测周期（SP）期间执行感测时，没有数据（DA）被写入显示器，所以感测将不那么复杂。 感测周期（SP）被选择为在连续的寻址周期（AP）之间发生，因为显示器具有维持光学状态的像素（10）比寻址周期（AP）持续时间长。 持续时间比寻址周期（AP）长得多的这样的保持期（HP）例如可以在诸如电泳显示器的双稳态显示器中使用。
