display device

Abstract

This case discloses a display device, which includes an optical film, a display panel and a frame structure. The frame structure supports the display panel and positions the optical film. The frame structure includes a frame body and at least one buffer bar. A protrusion is extended inwardly on at least one side of the frame body, and an oblique groove is arranged on the surface of the protrusion close to the optical film. The oblique concave A chamfered bottom surface in the groove moves farther away from the optical film as it advances toward the center of the frame body. At least one buffer strip is arranged in the oblique groove, and the buffer strip cooperates with the oblique groove to protrude from the surface of the protruding part to form an oblique-convex structure, so that the optical film can be positioned by the oblique-convex structure.

Description

technical field [0001] The present case relates to a display device, in particular, to a display device having a frame structure with an oblique-convex structure. Background technique [0002] The display device mainly includes components such as a backlight module, a frame, and a display panel. The frame body is extended inward with a protruding portion to support the display panel and maintain the distance between the optical film and the display panel, and a piece of elastic rubber will be attached on the contact surface of the protruding portion and the optical film. On the one hand, it can prevent the protruding part from contacting and rubbing and scratching the optical film, on the other hand, it can press the optical film to avoid warping of the optical film. [0003] However, due to the requirement of a narrow frame and a full-plane design of the display device, the inwardly extending length of the protruding portion of the frame body will be shortened, resulting i...

AI Technical Summary

Problems solved by technology

[0003] However, due to the requirement of narrow frame and full flat design of the display device, the inward extension length of the protruding part of the frame will be shortened, resulting in a relatively smaller area where it overlaps with the optical film, so the elasticity of the protruding part Rubber will sit on the cut edge of the optical diaphragm

However, after the display device is transported or due to thermal expansion and contraction of the optical film, the optical film at the edge of the corner will be stuck to the elastic rubber due to misalignment and displacement, and cannot return to its original position, thus forming arc-shaped waves. Phenomenon

Furthermore, reducing the thickness of the elastic rubber in order to avoid being stuck to the optical film will also cause the elastic rubber to have no pressure on the optical film, which will easily warp the optical film and form curtain-like ripples with poor brightness and darkness
