Problems solved by technology

[0005] However, it should be noted that the above-mentioned image signal classification unit classifies each frame of the RGBW image as an image classification unit, which can only classify the image by frame and improve the saturation of the entire frame. However, in most cases, in The saturation deterioration in different regions within the same frame is not the same, therefore, the prior art urgently needs a method to classify and improve the saturation of RGBW images by region within the same frame

Abstract

The invention provides a method and system for improving an RGBW-image saturation. The method for improving the RGBW-image saturation includes step A; according to an independently adjustable range of screen partition dynamic backlight, dividing the screen into a plurality of screen subareas; step B: partitioning a to-be-displayed RGBW image according to the screen subareas; step C: determining saturation-to-be-adjusted partitions in the partitions of the to-be-displayed RGBW image; and step D: when the to-be-displayed RGBW image is displayed, according to a preset proportion, reducing the backlight luminance of the saturation-to-be-adjusted partitions. The method and system for improving the RGBW-image saturation are capable of realizing refined adjustment of the saturation of the RGBW image.

Description

technical field [0001] The present invention relates to the technical field of image display, in particular to a method and system for improving the saturation of an RGBW image. Background technique [0002] In the field of image display, due to the low light mixing efficiency of the RGB three-color system and the poor color rendering of the mixed white light, people gradually use the RGBW four-color system to replace the RGB three-color system. The RGBW four-color system not only has red pixels (R), green pixels (G) and blue pixels (B), but also includes brightness enhancement pixels (W), so that all functions that can be realized by the RGB three-color system can be fully realized , and has the advantages of high light efficiency and relatively high color rendering. [0003] However, due to the addition of W sub-pixels in the RGBW four-color system, the saturation of the pure colors included in the image may deteriorate. Specifically, the absolute numerical values ​​of th...
