Embodiment Construction

[0048] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0049]Those skilled in the art can understand that mura compensation is by changing the grayscale value of each pixel, applying a lower grayscale value to a pixel with a relatively high display brightness, and applying a higher grayscale value to a pixel with a relatively low display brightness, In order to achieve the uniformity of screen brightness. However, when the brightness difference in the picture is large, the existing technology cannot meet the actual compensation requirement, and the compensation effect of the display screen mura is relatively poor. In order to solve the above problems, this embodiment provides a display brightness compensation meth...

Abstract

The invention provides a display brightness compensation method and device and equipment. The display brightness compensation method comprises the steps that brightness of each pixel block in a targetarea is acquired; the initial reference brightness is adjusted according to the brightness of each pixel block, and target compensation data of each pixel block are calculated according to the adjusted reference brightness and the brightness of each pixel block, wherein the target compensation data are within a predetermined compensation range; and according to the target compensation data of each pixel block, the brightness of each pixel block is compensated. According to the display brightness compensation method and device and the equipment, on the premise of ensuring compensation precision, the compensation effect of uneven brightness is improved, and the display performance of a display screen is improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a display brightness compensation method, device and equipment. Background technique [0002] Display devices such as liquid crystal displays (LCDs) have the advantages of high resolution, high brightness, no geometric deformation, high image quality, power saving, and thin body. At the same time, they are widely used due to their small size, light weight, and low power consumption. It is applied in consumer electronic products that people use daily, such as mobile phones, televisions, personal digital assistants, digital cameras, notebook computers, desktop computers, etc., and has become the mainstream of display devices. Among them, the display mold is the main part of the display device. Its manufacturing process is complicated and requires nearly a hundred processes. Therefore, various display defects will inevitably occur during the manufacturing process, amo...
