Benefits of technology

This patented technology allows for better image quality with less detail than previous methods like LCD displays. When there's no light on during operation, the screen will calculate its own grey scale characteristics based upon how well they were previously lit up. If any one section was brighter but still visible at certain points within this new region, indicating that another part had been activated (the shadow), the system automatically increases/decreases the overall luminance level accordingly without affecting other parts around us. By doing these things, we aim to improve our visual experience while also ensuring consistently high levels of clarity and sharpness from different angles.

Problems solved by technology

The technical problem addressed by this patented method for improving the quality (brightness) and dynamic range of displays with divided screens. This involves controlling how much light from each part of the screen should pass without affecting what it's supposedly displaying on top.

Abstract

The invention discloses a regional backlight control method, a display and a storage medium. The method comprises the following steps: acquiring a regional gray feature value which corresponds to eachbacklight region and is used for representing gray information when a backlight module runs; comparing the regional gray feature value of each backlight region with a preset feature threshold value so as to divide each backlight region into a highlight region or a dark region; increasing the backlight brightness of all the highlight regions, and reducing the backlight brightness of all the dark areas. According to the invention, after the gray feature information of the backlight areas after affiliation division is extracted, the backlight of each backlight area can be adjusted according to the specific display content of the display and the required image representation, the image gray representation and the dynamic contrast effect are improved, and a more real and natural image is presented.
