摘要： Self-referenced half-tone, gray scale liquid crystal display having pixels that are subdivided into subpixels (A1...AN). Each of the subpixels have transparent electrodes (31-39) with a liquid crystal material sandwiched between the electrodes. The electrodes of each subpixel and the liquid crystal dielectric constitute the subpixel capacitor which also functions as a control capacitor for the control capacitor. Each of the subpixel electrodes on one end of the dielectric overlap another subpixel but the electrode on the other end overlaps still another subpixel. The structure is such that the subpixel capacitors are electrically connected in series. The subpixels have electrodes of various areas and thus the subpixel capacitors of the pixel have different values. Application of a voltage across all of the series-connected subpixels of the pixel may result in the activation of none, one, or more subpixels of the pixel, in accordance with the magnitude of the voltage; the subpixels having the lower capacitances turning on first as the applied voltage is increased from zero, since the greater voltage drop occurs across the smaller-valued capacitors. Thus, each pixel of the display has a gray scale capability that is a function of the applied voltage.

AN）的像素的自参照半色调，灰度级液晶显示器。每个子像素具有夹在电极之间的液晶材料的透明电极（31-39）。每个子像素和液晶电介质的电极构成也用作控制电容器的控制电容器的子像素电容器。电介质一端的每个子像素电极与另一子像素重叠，而另一端的电极与另一子像素重叠。这种结构使得子像素电容器串联电连接。子像素具有各种区域的电极，因此像素的子像素电容器具有不同的值。在像素的所有串联子像素之间施加电压可以根据电压的大小导致像素的一个或多个子像素的激活; 具有较低电容的子像素首先作为施加电压从零增加，因为较小值电容器发生较大的电压降。因此，显示器的每个像素具有作为施加电压的函数的灰度级能力。

摘要： A method and apparatus for providing error voltage compensation in a flat panel display. Voltage errors in a column driver for a flat panel display are compensated for by first measuring the voltage level at each column during a known signal level period and comparing it against a known or reference value. This voltage error signal is then stored in an error memory according to column location. During normal operation of the flat panel display, the memory is accessed every time a particular column is scanned. The error voltage is retrieved and added to the raw video signal in order to remove any voltage offset which is introduced in the column driver electronics. This error voltage compensation substance eliminates any streaking which may appear on a display screen.

摘要： Apparatus and method are disclosed for providing a halo (background region) around selected image data in an anti-aliased image processing system. The anti-aliased image processing system applies a distribution function (601) to an image (impulse) point so that the impulse point contributes to the display (101, 500) for a plurality of pixels. In order to provide a halo, a second or halo distribution function (602), extending beyond the anti-aliasing distribution function (601), is assigned to selected impulse points. For the current pixel, the pixel for which the display attributes are being determined, the contribution to the current pixel from neighboring pixels for both the anti-aliasing distribution function (601) and the halo distribution function (602) are determined separately. Then the contributions from each source are combined to determine the display characteristics of the currently activated pixel. The invention provides a technique for combining or prioritizing contributions from display regions including overlapping sets impulse points.

摘要： A flicker-free liquid crystal display driver system driving two groups of pixels with alternating polarities. The spatial differentiation of the two groups, which may be accomplished in terms of even and odd rows or columns, is small so as to diminish detection by a human eye of the flicker in the display. The driver system incorporates a level shifter, switches, drivers, a driver switch control, a holding means and a storage means. Input signals to the system include that of intensity data, a clock and frames. The configuration of the driver system may be of a single-edge or redundant drive. The system may be digital or analog.
