Embodiment 1
[0071] An embodiment of the present invention provides an image processing method, which is applied to a liquid crystal display, such as Figure 5 As shown, the method includes:
[0072] Step 101. Obtain the gray scale value of each display partition in N display partitions, where N is an integer greater than or equal to 1.
[0073] The gray scale values of the display partitions include red gray scale values, green gray scale values and blue gray scale values. First of all, the liquid crystal display can decompose red, green and blue (RGB) pixel information by displaying the low-voltage differential signal (English full name: Low-Voltage Differential Signaling, English abbreviation: LVDS) of the partition. Then, the red gray scale value, the green gray scale value and the blue gray scale value are respectively obtained according to the red, green and blue (RGB) pixel information.
[0074] For example, get the sum of the grayscale values of all red pixels in the displa...
Embodiment 3
[0126] An embodiment of the present invention provides a liquid crystal display 30, such as Figure 11 shown, including:
[0127] An acquiring unit 301, configured to acquire the grayscale value of each of the N display zones, where N is an integer greater than or equal to 1;
[0128] A setting unit 302, configured to set the backlight value of the corresponding backlight partition according to the grayscale value of each of the N display partitions;
[0129] The adjusting unit 303 is configured to use the difference between the backlight value of the first display partition and the backlight values of N-1 display partitions except the first display partition, and the difference between the first display partition and The distance parameter between the N-1 display partitions, adjust the grayscale value of the first display partition, and obtain the adjusted grayscale value of the first display partition, the first display partition is the Each of the N display partitions. ...

Abstract
The embodiment of the invention provides an image processing method and a liquid crystal display, relates to the field of liquid crystal displays, and can effectively solve a problem that a picture displayed by a liquid crystal display has color cast. The method comprises the steps: obtaining the gray scale value of each of N display sections, wherein N is an integer greater than or equal to one; setting a backlight value of a corresponding backlight section according to the gray scale value of each of N display sections; Adjusting the gray scale value of the first display section according to the differences between the backlight value of the first display section and the backlight values of the (N-1) display sections except the first display sections and the distance parameters between the first display section and the (N-1) display sections, and obtaining the adjusted gray scale value of the first display section, wherein the first display section is any one of the N display sections. The method is used for solving the problem that the picture displayed by the liquid crystal display has color cast.
Description
technical field [0001] The invention relates to the field of liquid crystal displays, in particular to an image processing method and a liquid crystal display. Background technique [0002] At present, in the field of liquid crystal displays, quantum dot technology is usually used to realize high color gamut display of liquid crystal displays. Specifically, the quantum dot film is encapsulated between two layers of water and oxygen barrier films, and the quantum dot film contains quantum dots, and then the quantum dot film and the two layers of water and oxygen barrier films are placed above the diffusion plate or the light guide plate, and the blue light source is used Irradiate the diffusion plate or light guide plate, and the blue light passing through the diffusion plate or light guide plate is irradiated to the quantum dot film, and the quantum dot film converts the blue light into red light, green light and blue light, and the red light, green light and blue light form...
