Abstract

The invention provides a correction method for luminescence parameters of liquid crystal display devices and a device thereof, which is adaptable to the liquid crystal display field. The correction device for luminescence parameters of liquid crystal display devices comprises an optical test device, a test device support, a test control unit and an image generator. During the process of producing the liquid crystal display devices, the correction device for luminescence parameters of liquid crystal display devices can be utilized to enable the optical parameters to meet standard values through correcting LED luminescence parameters in corresponding areas which do not meet the standard values , thereby resolving the problems that the existing liquid crystal display devices are low in effect and high in cost during the production process.

Description

technical field [0001] The invention belongs to the field of liquid crystal display, and in particular relates to a method and a device for correcting luminescent parameters of a liquid crystal display device. Background technique [0002] Now liquid crystal display devices using LED backlight modules have appeared, but in the production process of such liquid crystal display devices, due to the discreteness of LEDs or other reasons, the optical parameters of liquid crystal display devices may not meet the requirements, such as insufficient brightness. Uniform or even color cast, in order to solve this problem, before the LED installation, the manufacturer will strictly select each LED, and then install the qualified LEDs on the liquid crystal display device, but this will lead to low production efficiency and high cost , there is currently no effective way to solve this problem. Contents of the invention [0003] The object of the present invention is to provide a method...
