Description

Technical Field

[0001] The utility model relates to a display module, more specifically, to an anti-separation fully-fitted display module. Background Art

[0002] Typically, the laminated structure of a fully bonded display module consists of a touch screen + optical bonding adhesive + LCD panel + backlight. The touch screen is glued to the LCD panel and the backlight is glued to the bottom. The backlight is suspended below the LCD panel, making it prone to separation and falling off. The backlight of a large-sized module is particularly heavy and more prone to falling off.

[0003] Chinese invention patent document CN202306056U discloses a liquid crystal display device comprising a front frame and a plastic frame, the plastic frame comprising a housing space within which the front frame is housed, the plastic frame comprising a first elastic element and a second elastic element, the first elastic element and the second elastic element elastically clamping the edge of the front frame. The plastic frame comprises side walls and a support wall extending from the side walls toward the center of the plastic frame, the side walls defining the housing space having a rectangular opening, the first elastic element being spaced apart from the support wall and extending from the side walls toward the center of the plastic frame, and the second elastic element being disposed on the support wall. The side walls comprise a first side wall, a second side wall, a third side wall, and a fourth side wall connected in sequence, wherein the first elastic element is disposed on each of the first, second, and third side walls, and the second elastic element is disposed on the support wall corresponding to the first, second, and third side walls, respectively. The front frame is a sheet-like structure with an opening, and the front frame is pushed from the fourth side wall between the first and second elastic elements. The liquid crystal display device also includes a liquid crystal panel, which is clamped between the front frame and the support wall. The liquid crystal panel enters the accommodating space in a direction perpendicular to the plane of the rectangular opening and is supported on the support wall. The second elastic element is a hook-shaped elastic member, one end of which is fixed to the support wall and the other end of which is bent and points toward the side wall corresponding to the support wall. The first elastic element is an elastic sheet, and the second elastic element is a block-shaped elastic member. Two second elastic elements are provided for each first elastic element, and the two second elastic elements are located on either side of the projection of the first elastic element on the support wall. The plastic frame includes a accommodating space, which houses a front frame. The plastic frame includes a first elastic element and a second elastic element, which elastically clamp the edges of the front frame. Clearly, this patent utilizes the first and second elastic elements of the plastic frame to clamp the edges of the front frame, simplifying the assembly process of the liquid crystal display device, improving production efficiency, and saving material for the front frame, thereby reducing the production cost of the liquid crystal display device. However, this structure does not solve the existing problem of backlight separation and detachment. Utility Model Content
