摘要： A display device (500) having a plurality of picture cells (502) is controlled by adding a phase change to the regular cyclic inversion scheme. Thereby, it is possible to overcome the drawbacks of DC build-up due to, e.g., de-interlaced images and images comprising rotating symbols and "ticker tape". The control involves receiving an image signal comprising image data relating to the picture cells. A respective electric field across each picture cell is controlled, in dependence on at least the image data, according to a first polarity inversion scheme where the polarity of the electric field is such that polarity inversion occurs at regular intervals, and according to a second polarity inversion scheme concurrent with said first polarity inversion scheme, where the polarity of the electric field such that polarity inversion occurs at pseudo-random intervals.

摘要： The invention relates to a driver (4) for driving a pixel (3) of a display panel (2). The driver (4) comprises a signal processor (5) which supplies a drive voltage (V) to the pixel (3) of the display panel (2) in response to an input signal (L). The input signal (L) represents the desired luminance (Ld) of the pixel during an addressing period (TP). When a luminance change of the pixel is requested during an addressing period (TP), the supplied drive voltage (V) is adapted to obtain an average luminance in the addressing period (TP) which is substantially equal to the desired luminance (Ld) during that addressing period (TP). The luminance, perceived by a viewer, during the addressing period (TP) during which a luminance change is requested is now equal to the desired luminance (Ld), reducing blurred edges and ghost images.

摘要： In an active matrix electroluminescent display device, an overall brightness level of an image to be displayed in a frame period is determined. A drive transistor of each pixel is controlled in dependence on an input drive signal for the pixel and on the overall brightness level, for example using a signal processor (30) to vary the pixel drive signals. This arrangement can control the pixels to limit the maximum currents drawn by the pixels, thereby limiting the cross talk effects resulting from voltage drops along row or column conductors. If an image is bright, the pixel drive levels across the image (or at least a part of the image) can be reduced, so that the maximum brightness is reduced.

摘要： A display device (1) of the matrix type is addressed using partial line doubling, i.e. a method in which one or more sub-fields for pixels are doubled, meaning that the same data is used for a set of pixels. Adjacent pixels in a row are addressed using different grey level realizations by applying different combinations of subfields. Partial line doubling is performed on sets of adjacent pixels in a column that are addressed using the same grey level realization. Two different addressing schemes may be used by applying either the standard pattern A/B or the second pattern (nx1 A/B). When applying the latter pattern partial line doubling is performed in a line skipping fashion.

摘要： The present invention relates to a method and a system of reducing motion blur in a liquid crystal cell. A basic idea of the invention is to process, in an LCD system, a luminance component (Y) of a picture frame to provide motion blur reduction, wherein overdrive is applied to the luminance component only. First, a luminance component related to a first picture frame is stored. Thereafter, a luminance component of a subsequent picture frame is acquired. To reduce motion blur in the LCD, a modified luminance component (Y') is created based on a difference between the value of the luminance component of the subsequent frame and the value of the luminance component related to the first frame. Hence, based on the value of the difference in the luminance components, and color components (U,V) of the subsequent picture frame, a drive voltage is applied to the LC cell.

摘要： A method for addressing a display device comprising applying a data signal to all column electrodes in a set and applying to a first row electrode an ON-select voltage (V rowseloN ) such that the pixels connected to said first row electrode can be switched ON by the data signal. Further, an OFF voltage (V row,OFF ) is applied to at least one second row electrode such that the pixels connected to said second row electrode are switched OFF regardless of the data signal. As a consequence of the inventive method, ON and OFF addressing can be performed during the same scan, and this effect is referred to as "dual action". The method according to the invention serves to reduce the dead time in addressing schemes and to decrease the required number of addressing slots.
