Problems solved by technology

However, this solution has a big disadvantage, that is, the cost will increase sharply. At the same time, to achieve good results, the backlight design must be a direct-type design. If the side-type backlight design is adopted, the light leakage problem will basically not be improved.

Embodiment Construction

[0046] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0047] Light leakage means that the screen LCD does not fit tightly with the frame so that the light from the lamp tube is directly transmitted. The light leakage of the LCD screen is a common problem. In a sense, the LCD screen basically cannot avoid the occurrence of light leakage, but it is only a matter of degree.

[0048] In the present invention, it is first necessary to understand the relevant factors of the screen display of the display screen. In the present invention, the gray scale of the display screen is processed to reduce the light leakage of the display screen. The gray scale refers to an image that can be defined as a binary image. Dimensional function f(x, y), where x and y are space plane coordinates, in any pair of coordinate axes (x, y), the size of f is called the intensity (intensity) or gray sca...

Abstract

The invention discloses a display screen image adjusting method. The display screen image adjusting method comprises the following steps: obtaining a to-be-displayed image on a display terminal and analyzing the image, to determine display information of the to-be-displayed image; according to the display information of the to-be-displayed image, determining display data, and processing the display data according to a preset rule, to obtain display control parameters; inputting the display control parameters to corresponding control functions, to obtain corresponding control curves; according to the corresponding control curves, adjusting the to-be-displayed image and displaying the image on the display terminal. The invention also discloses a display terminal and a readable storage medium. The scheme improves a light leakage problem of a display screen on the premise of not increasing any hardware cost, and the scheme maintains image quality standard of the display screen.

Description

technical field [0001] The invention relates to the field of display screens, in particular to a display screen image adjustment method, a display terminal and a readable storage medium. Background technique [0002] People have higher and higher requirements for the display quality and display clarity of the display screen, and different people have made improvements around the problems that occurred during the use of the display screen. [0003] However, light leakage from display screens has always been a problem faced by many manufacturers. There are many solutions to the problem of light leakage, but most of them are improved through hardware, and the cost is increased accordingly. Local Dimming is the most common and effective solution. With this technology, the backlight control of the TV can be changed according to the display content, and the corresponding backlight is reduced in the dark picture area, while it is increased in the bright picture area. Correspondin...
