Problems solved by technology

However, since the accommodating groove is generally a through hole that runs through the back frame, the optical film is only fixed with adhesive tape in the normal direction of the film, and it is easy to shift during assembly, causing the lugs of the optical film to partially jump out. The accommodating groove, and then the problem that the optical film may be damaged due to the step difference caused by the thickness of the back frame when the adhesive tape is attached

Embodiment Construction

[0074] Below in conjunction with accompanying drawing, structural principle and working principle of the present invention are specifically described:

[0075]In the drawings, the thickness of layers, films, panels, regions, etc., are exaggerated for clarity. Throughout the specification, the same reference numerals denote the same elements. It will be understood that when an element such as a layer, film, region, or substrate is referred to as being “on” or “connected to” another element, it can be directly on or connected to the other element, or Intermediate elements may also be present. In contrast, when an element is referred to as being "directly on" or "directly connected to" another element, there are no intervening elements present. As used herein, "connected" may refer to physical and / or electrical connection. Furthermore, "electrically connected" or "coupled" means that other elements exist between two elements.

[0076] It should be understood that although the...

Abstract

A display device includes a backlight module. The backlight module comprises a frame body, a light source unit and a first optical film; the frame body defines a light source space and is provided with a first layer part and a second layer part; the first layer part is arranged on one side of the light source space and provided with a containing groove, and the second layer part is arranged on theside, away from the light source space, of the first layer part and covers the containing groove; the light source unit is arranged in the frame body and partially located in the light source space;a first optical film is provided with a first convex lug, the first optical film is arranged on a light guide plate, and the first convex lug is contained in the containing groove.

Description

technical field [0001] The present invention relates to a display device; specifically, the present invention relates to a display device with a positionable optical film. Background technique [0002] Flat and curved display devices have been widely used in various electronic devices, such as mobile phones, personal wearable devices, televisions, vehicle hosts, personal computers, digital cameras, handheld video games, and the like. However, in order to improve the user's visual experience, the industry is still constantly improving the optical performance of the display device. [0003] For a traditional display device, the optical film of the display device is usually positioned through a back frame. In order to locate the relative positional relationship between the optical film and the display panel, usually an accommodation groove is directly opened on the side of the back frame. The groove attaches the lug of the optical film. However, since the accommodating groov...
