摘要： A de-jaggy processing method includes dividing a display area of a display into a plurality of sub-areas; providing a first table composed of gray-level weights associated with corresponding luminances of each primary color for each said sub-area; providing a second table composed of distance-gain weights each correspondingly associated with a distance between a sub-pixel and a reference point; and obtaining a corrected luminance of a sub-pixel of a pixel by multiplying an original luminance of the sub-pixel by a corresponding gray-level weight and a corresponding distance-gain weight.

摘要： An apparatus for performing subpixel rendering of an RGBW display panel is provided. The apparatus receives an input gray level data to acquire a luminance value of each subpixel of a RGB pixel set including two RGB pixels adjacent to each other. The apparatus calculates a rendered luminance value of each subpixel of a display pixel set including two display pixels adjacent to each other according to the luminance values. The display pixel set of the RGBW display panel includes red, green, blue, and white subpixels. The rendered luminance value of the white subpixel of one of the display pixels is determined according to the saturation value of the corresponding RGB pixel and the luminance value of each subpixel of the corresponding RGB pixel. The apparatus acquires a gray level value of each white subpixel of the display pixel set according to the rendered luminance values.

摘要： An image display system includes a motion detection device that detects motion of an object in an input image; and a black data insertion device that inserts black data in one frame of the input image, thereby generating an output image. A duty cycle of the inserted black data in the frame is changed according to a result of the motion detection device.
