Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of COG detection jigs, in particular to a structure capable of delaying the life of COG jigs. Background Art
[0002] COG refers to bonding the chip to the glass. At present, COG plus backlight is the module LCM. However, before assembling the module, in order to avoid sticking bad COG glass to the backlight, we will have a process to detect the quality of COG glass, so we will need to use a detection fixture. Because COG glass itself is not luminous, it needs a light source to see the displayed image clearly during detection. In order to match the corresponding backlight conditions, the corresponding test fixture usually uses the same model of backlight when assembled into the module. The detection method is to put the COG on the backlight to simulate the conditions of sticking COG to the backlight, so as to detect whether there is a problem with the image display. However, this method requires frequent contact with the COG glass, and the surface of the backlight is a film. At this time, it will inevitably be scratched and scratched by the COG glass, affecting the light source and the displayed image. Therefore, the fixture maintenance personnel can only frequently replace the backlight on the detection fixture, which affects efficiency and increases costs. Utility Model Content
