Description

Display module

technical field

The present invention relates to a display module; in particular, the present invention relates to a display module with a waterproof adhesive tape.

Background technique

Display modules are ubiquitous in human life. Whether it is work, travel, or daily leisure, the traces of display modules are indispensable. In order to respond to different usage environments, the development of display module technology has also designed different degrees of waterproof effects, so that people can find corresponding designs for different usage needs.

In theory, the higher the waterproof level of the display module, the thicker the outer layer needs to be. To reduce the thickness of the outer layer, conventionally, a waterproof glue can be added to the gap between the outer frame and the display panel. However, the width of the gap between the outer frame and the display panel may be different due to the degree of warpage of the outer frame during the manufacturing process, which makes it difficult for the volume of the waterproof glue to fit together, resulting in a gap. In addition, when the outer frame or the display panel is stressed, the waterproof adhesive may be peeled off and the waterproof effect may be reduced, or the liquid crystal of the display panel may be pressed and damaged. In addition, the waterproof adhesive directly contacts the outer frame and the display panel, which may cause sticking and difficult to remove, thereby limiting the possibility of heavy work.

The frame body has a side wall and a top wall, the side wall has an inner side surface, and the top wall has an end edge and an outer side surface, wherein the side wall is connected to the side of the top wall opposite to the end edge. The edge of the display panel faces the inner side surface of the side wall. In addition, the display panel has a top surface, the top surface has an overlapping area, and the frame body and the overlapping area sandwich a first gap. The first waterproof tape has a first part and a second part, the first part extends outward from the end edge of the top wall to the outer side and is directly or indirectly pasted, and the second part is pasted on the overlapping area of the top surface. With this arrangement, the first waterproof adhesive tape can buffer warpage of different degrees, and reduce or avoid the possibility of peeling off when the frame body or the display panel is stressed. In addition, the first waterproof tape can also provide a simpler way to remove and re-stick.
