Technical Field
[0001] The utility model relates to the technical field of display modules, in particular to a display module for preventing a backlight pad from being short-circuited during welding. Background Art
[0002] When manufacturing LCD screens, the backlight FPC of the backlight module needs to be welded to the corresponding backlight welding area of the module FPC. The existing backlight pads are basically designed with equal width and equal spacing. For example, the width of both the negative and positive pads is 0.5mm, and the gap between adjacent pads is also 0.5mm. This design will cause manual welding or semi-automatic welding to be performed without accurate alignment. After power is turned on, the product will short-circuit, causing failure to light up, damage and scrapping. If fully automatic high-precision welding is used, the cost is relatively high.
[0003] Therefore, the prior art has defects and needs to be improved. Utility Model Content
[0004] The utility model aims to overcome the deficiencies of the prior art and provide a display module which can prevent a backlight pad from short-circuiting during welding.
