Embodiment Construction

[0054] Relevant detailed content and technical description of the present invention, now in conjunction with accompanying drawing, explain as follows:

[0055] Please refer to FIG. 11 , which is a schematic diagram of the image processing method of the present invention. A color distribution calculation unit 32 inputs the original image color RGB data, and the color distribution calculation unit 32 judges and classifies the color of each pixel of the input image, based on the numerical relationship of the RGB data of the color, the color is located in the color space The relationship is divided into block 1 B1 and block 2 B2 (as shown in Figure 12), and the ratio value of the input image color in any block of block 1 B1 or block 2 B2 is calculated (subsequent calculation input The ratio p (0≤p≤1) of the image color in the block 2 B2 illustrates the present invention).

[0056] Wherein the RGB data value relationship of the color located in Block 1 B1 is: max(R, G, B) / min(R, G...

Abstract

The invention discloses a video processing device and method to improve brightness and quality of display panel, which comprise: using a color distribution calculation unit to decide and classify original video color data and calculate the rate of all data in the second block; using a control factor generation unit to determine a conversion control factor to convert original RGB data into (R'G'B'W') data and a backlight brightness control factor for a control unit to control the backlight brightness.

Description

technical field [0001] The invention relates to an image processing device and method for improving the brightness and image quality of a display panel, aiming at an RGBW color system that can still display high-quality colors without sacrificing brightness enhancement, maintain the quality of image display, and achieve increased The purpose of doubling the brightness, maintaining the hue and color saturation, and maintaining the contrast quality of the image. Background technique [0002] In recent years, panel pixels are composed of 4-color sub-pixels (sub pixels), in addition to red light (R), green light (G) and blue light (B), there is also white light (W). The RGBW color system can improve the light use efficiency of the liquid crystal display, wherein the arrangement of the sub-pixels is shown in FIG. 1 and FIG. 2 . [0003] US Patent No. 5,929,843 proposes a numerical conversion processing method of RGB-to-RGBW image data, as shown in FIG. 3 . Wherein, R, G, B are ...
