Temporal and spatial color mixing methods for pixel arrays

Abstract

The invention provides a temporal and spatial color mixing method of a pixel array. The pixel array includes a plurality of unit arrays repeatedly arranged along the row and column directions. Each sub-pixel is displayed according to the gray scale value corrected by the offset value. The offset values ​​of each sub-pixel in the four pixel groups in the same column form four corresponding offset value groups. The color mixing method includes: taking four consecutive frames of the pixel array as a time unit, and in each frame of the same time unit, in the same In the four pixel groups in the same column of the unit array, the four offset value groups are arranged in different orders. In the same time unit and the same unit array: the average offset values ​​of each pixel group are equal. In each frame, each The respective offset values ​​of the offset value groups are arranged identically. The invention eliminates the jitter effect and block effect caused by the traditional time and space color mixing in the sense of human eyes, and improves the realism, smoothness and aesthetic feeling of display.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a temporal and spatial color mixing method of a pixel array. Background technique [0002] Liquid crystal display has high resolution, low energy consumption, and volume and weight are much smaller than CRT display. At present, liquid crystal display has replaced traditional CRT display and occupies a dominant position in the display field. [0003] Liquid crystal (LCD: Liquid-crystal-display) is a liquid-like chemical substance. When affected by an external electric field, its molecules will produce a precise and ordered arrangement. If the alignment of the molecules is properly controlled, the liquid crystal molecules will allow light to pass through. Whether it is a notebook computer or a desktop system, the LCD display screen used is a layered structure composed of different parts. The last layer is a backlight layer that emits light and is composed of fluorescent substanc...

Problems solved by technology

[0011] The traditional simple time or space color mixing realizes the display of high-digit color information with a low-digit liquid crystal display, but there is a visual jitter effect, which is specifically manifested in that the picture seen by the human eye is not smooth, and the jitter of the image can be perceived

The difference between the gray scale is only at the pixel level, which is likely to cause a block effect on the display. The human eye perceives that the picture seems to be divided into small blocks, which affects the smoothness and aesthetics of the display.
