Embodiment Construction

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0039] It should be noted that during the display process of the display panel, the display brightness formula of the display panel is as follows:

[0040] B=B L *T r =(D*B LA )*(n / 255) r

[0041] Among them, B is the display brightness of the pixel, B L is the brightness of the backlight, T r is the transmittance of the display panel, D is the duty cycle of the backlight, B LA Set the brightness of the reference circuit for the backlight, n is the gray...

Abstract

The invention provides a display signal processing method, device and display device, relates to the field of display technology, and solves the problem of crosstalk ghosting in existing 3D display images. A display signal processing method, the method comprising: obtaining the gray scale average value of at least one display area in the previous frame image and the gray scale average value of at least one display area in the current frame image; comparing the at least one display area in the current frame The size of the grayscale average value and the grayscale average value of the display area of ​​the previous frame; when the grayscale average value of the current frame of the display area is greater than the grayscale average value of the previous frame, output to improve the corresponding display area The backlight control value of the brightness of the light-emitting unit; when the gray-scale average value of the current frame of the display area is smaller than the gray-scale average value of the previous frame, output the backlight control value to reduce the brightness of the light-emitting unit corresponding to the display area.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display signal processing method, device and display device. Background technique [0002] Shutter Glass (Shutter Glass) 3D technology is a kind of glasses-type 3D display (it uses a pair of active LCD alternate shutter glasses, so that the user's left eye can see the image of the left eye in time-sharing, and the right eye can see the image in time-sharing. When the right eye image is seen from time to time, the left eye and the right eye receive two left and right eye images with parallax and merge them into one in the brain, thus realizing 3D display. The LCD screen with 120Hz or higher frequency is used to display the left and right images in time sharing Eye and right eye images, and drive the liquid crystal display with a general driving method. Due to the problem of certain response time in the deflection of liquid crystal molecules, when the left eye image and ...
