摘要： Bi-stable electrophoretic display device (1) having a normal mode and a scrolling mode, in which image transitions are effected by causing the charged particles (8,9) to toggle between the intermediate optical states (e.g. grey-to-grey) or between an extreme optical state and an intermediate optical state (e.g. white-to-light grey), with a corresponding short update time t scroll. When the device (1) enters a scrolling mode in response to a scrolling command from a user, picture elements are first driven to a special scrolling optical. state, after which drive waveforms for scrolling mode are used for fast toggling between two scrolling states. An increased scrolling speed and very short scrolling time can be realised, without adversely affecting image quality during a normal mode.

摘要： The present invention relates to an electrophoretic display device (1) and a method of controlling gray level transitions in an electrophoretic display device. The idea of the invention is that, in an electrophoretic device where drive signals (Dr) are applied to display device electrodes (5, 5') to effect movement of the display particles (8, 9), such that the particles correspond to image information to be displayed, a second electric signal (Ne) is applied to the display device electrodes. This second signal is arranged to decrease the ability of the particles to respond to the drive signal. By employing the second signal in accordance with the invention, more distinct optical states can be attained and the accuracy of the states becomes higher. Thus, the optical states are easier to reproduce due to a more well-defined particle control by means of the drive waveform according to the present invention.
摘要翻译：本发明涉及一种电泳显示装置（1）和一种控制电泳显示装置中的灰度级转换的方法。本发明的思想是在电泳装置中，其中驱动信号（Dr）施加到显示装置电极（5,5'）以实现显示颗粒（8,9）的移动，使得颗粒对应于图像要显示的信息，第二电信号（Ne）被施加到显示装置电极。布置第二信号以降低颗粒响应驱动信号的能力。通过采用根据本发明的第二信号，可以获得更多不同的光学状态，并且状态的精度变得更高。因此，由于通过根据本发明的驱动波形的更明确的粒子控制，光学状态更容易再现。

摘要： An image is updated on a bi-stable display (310) such as an electrophoretic display by using cyclic rail-stabilized driving, where an image transition is realized either directly via a single drive pulse (D1), or indirectly via a reset pulse (R) and a drive pulse (D2) of opposite polarity. First shaking pulses (SI) are applied to the bi-stable display, when the at least one image transition is realized indirectly, e.g., during at least a portion of the reset pulse and/or the drive pulse of opposite polarity. Furthermore, second shaking pulses (S2) are applied prior to the single drive pulse, or prior to the reset pulse and the drive pulse of opposite polarity. The shaking pulses in either case may include initial shaking pulses (810, 820) and final shaking pulses (815, 825), which have a reduced energy.

摘要： A display device (101) has groups of display elements (118), which are changed from one optical state to another optical state by applying a waveform sequence of potential differences. The waveform enables particles (108, 109) to occupy a position corresponding to the other optical state and includes standard reset, over-reset and grayscale drive. The standard reset part of the waveform applies a potential difference, which is proportional to a distance the particles (108, 109) must move to reach one of the extreme optical states and the over-reset is independent of the distance. Grayscale or color scale accuracy is improved and direct charge on a pixel may be balanced over time with consequent grayscale drift compensated by tuning the grayscale driving pulse.

摘要： Electrophoretic display units (1) comprising pixels (11) situated between common electrodes (6) and pixel electrodes (5) need, for shortening the total image update times, increased driving voltages across the pixels (11) which endanger transistors (12) coupled to the pixel electrodes (5).These increased driving voltage (V 6 ) to the common electrode (6). To protect the transistors (12) against these increased driving voltages, a setting signal (S 1 , S 2 ) is supplied to the pixel electrode (5) via the transistor (12) for reducing a voltage across the pixel (11) resulting from a transition in the alternating voltage signal (V 6 ). During driving frame periods (F d ) data pulses (D 1 , D 2 , D 3 , D 4 , D 5 , D 6 ) are supplied, and during setting frame periods (F s ), the setting signals (S 1 , S 2 ) are supplied.

摘要： An display device (301) has reduced memory (314) requirements for temperature compensation data. A scaling factors (433) for various temperatures and a look-up table for a waveform which is optimized to drive the grayscale for a given display temperature are stored in memory (314). The waveform for a particular temperature of the display (301) is derived from the look-up table and scaling factors (433). At some temperatures, only certain parts of the waveform need be varied, and only these parts require accurate scaling from the look-up table.

摘要： An image is updated on a bi-stable display (310) such as an electrophoretic display by using voltage waveforms (600, 620, 640, 660; 700, 720, 740, 760; 800, 820, 840, 860) that are configured such that voltage changes are constrained to a subset of possible voltage levels during specific frame times. The specific frame times may occur during datadependent portions of the waveforms, such as a reset portion (R) and/or a drive portion (D, D1, D2). Due to the reduced voltage swing, the supply voltage can be reduced, resulting in reduced power consumption. Moreover, the frame time (FT') can be shortened during the data-dependent portions of the waveforms to increase the greyscale accuracy and number of grey levels. At other frames times, the voltage levels can vary throughout the full range of possible voltage levels, while a standard frame time (FT) is used.

摘要： The electrophoretic display panel (1) for displaying a picture has a plurality of picture elements (2) and drive means (100). Each picture element (2) has two electrodes (3,4) for receiving a potential difference and charged particles (6) being able to occupy positions between the electrodes (3,4). The drive means (100) are able to supply a sequence of potential difference pulses to each picture element (2). Each sequence has a response-changing pulse for changing the ability of the particles (6) to respond to the potential difference without substantially changing the position of the particles (6), and a picture pulse for bringing the particles (6) into one of the positions for displaying the picture. For the display panel (1) to be able to display a picture of relatively high picture quality, even when the frame period is relatively large and the number of potential difference values for the picture pulse is relatively low, with respect to at least a number of the picture elements (2), the drive means (100) are further able to supply for each picture element (2) out of said number a part of the picture pulse before an end of the response-changing pulse.
