Abstract

The invention relates to a detection device which is used for detecting the defects of a backlight module; the detection device comprises a test table, a base and a positioning device, wherein an upper cover and a test plate are arranged on the test table; the upper cover is of a frame structure, wherein the middle part of the frame structure is rectangular hollow; a display panel is arranged at the rectangular hollow part; the test plate is used for bearing the backlight module; the upper cover is in pivot connection with the test plate; the base is in pivot connection with the test plate; and the positioning device is used for fixing the test plate and the base at a selected angle. According to the device, the display panel for test is directly fixedly arranged on the test device; in detection, only the backlight module to be measured is changed continuously without consuming labor and working to assemble or disassemble, therefore, the detection time is reduced, the detection efficiency and effect are improved, and the service life of the display panel is effectively prolonged.

Description

technical field [0001] The invention relates to a detection device, in particular to a detection device for detecting defects of a backlight module. Background technique [0002] At present, the competition in the liquid crystal display market is becoming more and more fierce. Both manufacturers and consumers have put forward higher requirements for the quality of liquid crystal displays. As an important part of the display, the backlight module has a direct impact on the quality and yield of the finished liquid crystal display. and yield. If the quality of the backlight module can be quickly and effectively intercepted, it will be beneficial to the improvement of the quality and yield of the liquid crystal display. [0003] Generally, backlight module manufacturers can only intercept some defects of the backlight module itself. When there are some slight black spots or white spots on the optical film of the backlight module, if the proportion of defective products is high...
