Embodiment Construction

[0033] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Apparently, the described embodiments are only some of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of this application.

[0034] It should be noted that, during the assembly process of the liquid crystal display, it is necessary to judge the level of the display module in order to select a suitable display module.

[0035] In the process of determining the level of the display module, it is necessary to use the backlight module as the light source of the display module, so as to realize the level determination of the display module.

[0036] It should be noted that in the process of determining the...

Abstract

The embodiment of the present application discloses a detection method and device for a backlight module, wherein the detection method includes: acquiring the display screen of the display module during the level determination process of the display module; acquiring the display screen of the display module; The average brightness value of the screen; according to the average brightness value of the display screen, it is determined whether the backlight module is abnormal. This solution can realize real-time monitoring of the backlight module.

Description

technical field [0001] The present application relates to the technical field of optical measurement, and in particular to a detection method and device for a backlight module. Background technique [0002] The backlight module is one of the key components of the liquid crystal display. Since the liquid crystal itself does not have light-emitting properties, a light source must be added to the bottom of the liquid crystal display (LCD, Liquid Crystal Display) panel to achieve a full color display effect. The function of the backlight module is to supply a planar light source with sufficient brightness and uniform distribution, so that the LCD can display images normally. Therefore, when judging the grade of the LCD panel, if the backlight module is abnormal, it will affect the judgment of the grade of the LCD panel, resulting in abnormal product grading. [0003] In the related art, the luminance of the backlight module is generally measured by a measuring system composed o...
