摘要： The electrophoretic display panel (1) for displaying a picture and a subsequent picture has drive means (100) which are able to control for each pixel (2) the potential difference to have a picture value to provide the pixels (2) with a respective picture appearance being either extreme or intermediate, subsequently to have an inter-picture value to provide the pixels (2) with a respective inter-picture appearance, and subsequently to have a subsequent picture value. For the display panel (1) to be able to provide the pixels (2) with the inter-picture appearances which are in general relatively little visible, the drive means (100) are able to control for each pixel (2) an estimate potential difference as the inter-picture value to provide the pixels (2) with a respective estimate picture appearance as the inter-picture appearance.

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 tscroll. 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 realized, without adversely affecting image quality during a normal mode.

摘要： In a first display mode, only the information in a first sub-area (W1) of the display screen of a bi-stable matrix display (100) has to be updated. In a second display mode, the information in a second sub-area (W2) of the display screen has to be updated. The information in the first sub-area (W1) is displayed using optical states which require first drive voltage waveforms (DV1) having a maximum duration equal to a first image update period (IUP1). The information in the second area (W2) is displayed using optical states which require second drive voltage waveforms (DV2) having a maximum duration equal to a second image update period (IUP2). The optical states allowed to be used during the first mode are selected to obtain a first image update period (IUP1) which is shorter than the second image update period (IUP2). In this manner, the refresh rate of the information in the first area (W1) is higher than the refresh rate in the second area (W2).

摘要： An electrophoretic display device is driven by carrying out a first display addressing cycle (FIG. 3A), in which the display is addressed as a first set of row groups (52), the same column data set being applied to each row of the row group simultaneously. The number of row groups (52) is less than the number of rows (50), such that at least one row group comprises a plurality of rows. At least one further display addressing cycle (FIG. 3B) addresses all rows of the display with independent image data. This method addresses groups of rows together using the same column data, and thereby reduces the addressing time. The image is presented after the first addressing cycle as a low resolution image, in particular with low vertical resolution. The subsequent addressing cycles then progressively improve the image quality to the final desired image.
摘要翻译： 通过执行第一显示寻址周期（图3A）来驱动电泳显示设备，其中显示器被寻址为第一组行组（52），相同的列数据组被应用于行的每一行 同时进行。 行组（52）的数量小于行数（50），使得至少一行行包括多行。 至少一个另外的显示寻址周期（图3B）用独立的图像数据寻址显示器的所有行。 该方法使用相同的列数据一起处理一组行，从而减少寻址时间。 在第一寻址周期之后，图像作为低分辨率图像呈现，特别是具有低垂直分辨率。 随后的寻址周期随后逐渐地将图像质量提高到最终期望的图像。

摘要： A display device comprising a plurality of pixels (200), each pixel comprising charged particles (28) that are movable between storage (20) and active (24) regions of the pixel under the influence of an electric field. The number of charged particles (28) within the active region (24) determines the optical appearance of the pixel, and the storage region (20) is used for storing charged particles (28) away from the active region (24). Each pixel (200) comprises enough charged particles to saturate both the storage and active regions, such that moving additional charged particles to those regions does not significantly affect the optical appearances of those regions. Hence there are always enough charged particles (28) available within the pixel (200) to saturate the active region (24), and the storage region (20) may be saturated even when the active region (24) is saturated.
摘要翻译： 一种显示设备，包括多个像素（200），每个像素包括在电场的影响下可在像素的存储（20）和活动（24）区域之间移动的带电粒子（28）。 有源区域（24）内的带电粒子（28）的数量确定像素的光学外观，并且存储区域（20）用于将带电粒子（28）远离有源区域（24）存储。 每个像素（200）包括足够的带电粒子以使存储和有源区域饱和，使得将附加带电粒子移动到那些区域不会显着影响那些区域的光学外观。 因此，在像素（200）内始终存在足够的带电粒子（28），以使有源区域（24）饱和，并且即使当有源区域（24）饱和时，存储区域（20）也可能是饱和的。

摘要： The present invention relates to an electrophoretic device where a viewing electrode, which is used to attract an electrophoretic medium to a viewing area, is divided into a first (25) and a second (27) sub-electrode which are separated on the viewing area. When the electrophoretic medium is to cover the viewing area, the electrophoretic medium is first collected at one of the sub-electrodes and is then spread over the viewing area by applying a pulse between the sub-electrodes.

摘要： The invention relates to a display device for visually reconstructing an image (330) from an encoded image (320), such a device being particularly useful in the field of visual cryptography. The display device has two stacked liquid crystalline layers (410, 420) with individually addressable pixels. One layer (420) renders encoded image data together with a randomization pattern, and the other layer (410) only renders a randomization pattern. If the patterns match, the display device shows a visually reconstructed image (330) to a viewer. Means are provided for LC layers, such as a birefringent layer (414) between the two LC layers. Alternatively, two twisted nematic LC layers can be used having opposite twist directions. Such means were found to improve an image quality of the visually reconstructed image, and can in fact be advantageously applied in any display system including a plurality of LC layers cooperating for forming an image.
