Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of display module structures, in particular to a structure for preventing single-layer glass of a display module from breaking. Background Art
[0002] At present, in order to improve the strength of the product and protect the single-layer glass, the existing display modules usually apply silicone glue on both sides of the binding position of the IC and FPC of the lower glass before full bonding to fill the gap between the lower glass and the cover plate after full bonding. However, since the appearance of the current mobile phone display glass is a non-square structure, the corners on both sides of the lower glass are arc-shaped, and the shape of the silicone glue on the upper end of the single-layer glass is difficult to control. There will often be overflow or insufficient glue at the edge of the lower end of the glass. Especially when the amount of glue is small, it cannot play a protective role. Therefore, when the whole machine falls, the impact force is transmitted from the middle frame of the whole machine to the display module, and the impact force acts on the single-layer area of the backlight squeeze glass. If the amount of silicone glue on the single-layer glass is small, it is easy to cause cracks and collapse of the edge of the silicone glue. Utility Model Content
