Liquid crystal module with frame embedded

Abstract

The invention discloses a liquid crystal module with a frame embedded. The liquid crystal module is characterized by comprising a liquid crystal display screen, a backlight board, a printed circuit board and the frame, the liquid crystal display screen is mounted on the backlight board, the printed circuit board is mounted below the backlight board, the liquid crystal display screen, the backlight board and the printed circuit board are integrally mounted in the frame, a hollow area is formed in the middle of the frame, four lug-shaped corners are connected by narrow edges, each narrow edge is U-shaped, and grooves, protrusions and elongated through holes are formed in the inner side of each narrow edge; the backlight board is an LED backlight board, a temperature sensing strip is arranged on the side face of an area where the backlight board is connected with the printed circuit board, and a temperature sensing transition interval is formed in the middle of the temperature sensing strip and mounted at a position aligned at the elongated through holes in the narrow edges of the frame. A mode of connecting the backlight board with the lateral side of the printed circuit board through metal bolts is omitted, the problem of lateral light leakage of the liquid crystal display screen, the backlight board and the printed circuit board is solved, and the liquid crystal module is small in assembly gap, convenient for integral assembly and suitable for batched popularization and use.

Description

technical field [0001] The invention relates to the technical field of liquid crystal modules, in particular to a liquid crystal module with a bezel. Background technique [0002] The liquid crystal module is the inner tank of the digital signage. It has all the functional parts of the digital signage, has all the functions of the digital signage, and has a complete and compact structure, but it does not have the outer box of the original digital signage. This product is mainly used for installation in a relatively high environment. place. When installing the printed circuit board and backlight board in ordinary liquid crystal modules, holes or slots are usually drilled on the printed circuit board, and fixing bolts are used to fix the installation. When the modules are spliced ​​and used, the gap is large; at the same time, the side of the printed circuit board and the backlight board are prone to light leakage, which seriously affects the overall performance of the liquid...

Problems solved by technology

When installing the printed circuit board and backlight board in ordinary liquid crystal modules, holes or slots are usually drilled on the printed circuit board, and fixing bolts are used to fix the installation. When the modules are spliced ​​and used, the gap is large; at the same time, the side of the printed circuit board and the backlight board are prone to light leakage, which seriously affects the overall performance of the LCD module
