Image processing method, image processing device, and display device

Abstract

The invention discloses an image processing method, an image processing device, and a display device. The image processing method comprises steps that an original gray scale value of each pixel point of a to-be-displayed image is acquired, and the pixel points are corresponding to first type pixels and second type pixels, which are arranged in rows and in columns on a display panel, and are arranged in an alternate way in a row direction and in a column direction; whether the pixel points are high frequency pixel points are determined according to the original gray scale values; when the pixel points are not the high frequency pixel points, and the pixel points are corresponding to the first type pixels, the first gray scale values are output, and the first scale values are greater than the original gray scale values corresponding to the pixel points; when the pixel points are corresponding to the second type pixels, second gray scale values are output, and the second gray scale values are smaller than the original gray scale values corresponding to the pixel points, and therefore the first type pixels are corresponding to the first gray scale values, and the second type pixels are corresponding to the second gray scale values, and the to-be-displayed image is displayed. The chrominance visual angle and the light transmittance of the display device are improved.

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...

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
