Image processing method, image processing device and display device

Abstract

An image processing method, an image processing device and a display device are disclosed. The image processing method comprises: acquiring an original gray scale value of each pixel point of a to-be-displayed image, wherein the pixel points correspond to first type pixels and second type pixels, which are disposed alternately in a row direction and a column direction; judging whether the pixel point is a high-frequency pixel point according to the original gray scale value; if not, outputting a first gray scale value when the pixel point corresponds to a first type pixel; and outputting a second gray scale value when the pixel point corresponds to a second type pixel, so the first type pixel and the second type pixel display the to-be-displayed image using the corresponding first gray scale value and the corresponding second gray scale value, respectively.

Description

technical field [0001] Embodiments of the present invention relate to image processing technologies, and in particular, to an image processing method, an image processing device, and a display device. Background technique [0002] With the development of liquid crystal display technology, high image quality has become the main indicator of major display device manufacturers. Among them, chromaticity and viewing angle, as an important indicator of image quality, have become an important research for various panel manufacturers to produce vertical alignment liquid crystal display devices. direction. [0003] At present, in order to solve the problem of angular misalignment in a vertical alignment liquid crystal display device, each pixel of the display panel is usually divided into a main pixel and a sub-pixel, and different driving voltages are applied to the main pixel and the sub-pixel. However, the existing design often needs to add metal wiring or thin film transistor el...

AI Technical Summary

Problems solved by technology

However, the existing designs often need to add metal wiring or thin film transistor elements on the display panel to drive sub-pixels, especially in the design of high-resolution display devices, which will greatly reduce the area of ​​the light-transmitting area and reduce the transmittance of the display device. light rate
