摘要： A display device (600) is driven in a number of sub-fields. Each of the sub-fields is for outputting a respective illumination level by the display device. In each sub-field, a pixel of the displayed image may emit an amount of light corresponding to the particular sub-field, depending on whether it is switched on or not. A required intensity level of the pixel is realized by selecting an appropriate combination of sub-fields in which the pixel is switched on. A plurality of sub-fields is available to realize a particular intensity level. The image display unit (604) has a selection unit (608) that is arranged to select the combination of sub-fields for a particular pixel from a plurality of available combinations in such a way that any artifact is as small as possible. This selection is carried out on the basis of a further pixel in the current image.

The flat panel display (PD) is driven in a sub field mode wherein a field period (Tf) of a received display information (Pi) is divided (1) into consecutive sub field periods (Tsf) having an address period (Tp) preceding a display period (Ts). within a field period (Tf), a predetermined order of weight factors (Wf) each associated with a corresponding one of the display periods (Ts) is generated (1). The electrodes (Sc, D, Su) are interconnected in at least two groups (Sce, Sco; Sue, Suo). Drive signals corresponding to the weight factors (Wf) are supplied (2,3,4,5; 2,3,4,5,6) to each of the at least two groups. Within a same field period (Tf), the predetermined order of weight factors (Wf) is adapted to associate a different order of weight factors (Wf) to the display periods (Ts) of the at least two groups of electrodes (Sce, Sco; Sue, Suo).

摘要： The invention relates to a micro-electro-mechanical system comprising a ciliary actuator (100) having a flexible electrode unit (FE) and a stationary electrode unit (SE), wherein the flexible electrode unit (FE) can be rolled-up or out according to a voltage (VPMA) applied between the flexible and the stationary electrode unit (SE). The invention provides means that allow to bring the actuator into a stable intermediate state (INT) between the totally rolled-up (UP) and the totally rolled-out (DWN) state. In one embodiment of the invention, the means comprise the application of a definite voltage and/or the transfer of a definite charge to the actuator. In another embodiment, the stationary electrode unit (SE) is composed of several segments of different drive electrodes (SE1, SE2) that can selectively be activated to roll the actuator (100) to a desired position.

摘要： A system and method for motion compensation of color sequential displays, receiving a motion image data input, extracting an estimate of a motion of an image portion represented in said image data input with a motion estimator, and calculating, for a time instance of display of each image subframe of an image frame, a compensated representation for reducing display artifacts with a processor, wherein each subframe represents a different aspect of the image frame. The subframes are preferably different color planes of the image frame. The processor preferably performs a bilinear interpolation where the compensated image boundary does not fall on a display pixel boundary. The motion compensation algorithm is preferably robust in the face of erroneous motion vectors. The system and method is advantageously used in single panel liquid crystal display projection systems, although the techniques are applicable to various image display technologies.

摘要： In a driver circuit (1) for a matrix display with pixels (Pij) associated with cross points of data electrodes (DEj) and select electrodes (SEi), data signals (DSj) are supplied by the data driver (12) to the data electrodes (Dej) to store data voltages in pixels (Pij) associated with a selected one of the select electrodes (SEi). A bias circuit (13) increases a bias current (IB) of the data driver (12) only when an edge of at least one of the data signals (DSj) occurs or is expected to occur. The bias current (IB) is selected to be very small if no edge of the data signal (DSj) occurs or is expected to occur, and the power dissipation in the data driver (12) will be lowered. If no edge occurs or is expected to occur, the bias current (IB) has a low value during the whole select time (also referred to as address time) of a row (Ri) of pixels (Pij). If an edge occurs, there are several possibilities to allow the required short duration of the data setup time: the bias current (IB) has a high value during the whole select time of a row (Ri), or only during the data setup period.
