Technical Field

[0001] The utility model relates to the technical field of liquid crystal display screen production, in particular to a liquid crystal display screen module which can avoid assembly damage. Background Art

[0002] The display module is one of the main components of the finished display, mainly composed of display panel, PCB circuit board, driver IC, resistor, capacitor and plastic kit;

[0003] When assembling the LCD screen module currently used, the LCD screen panel is generally fixed on the PCB circuit board and clamped and fixed by screws, or double-sided tape is set between the LCD screen panel and the PCB circuit board and bonded and fixed. The former is easily compressed and damaged around the LCD screen panel by the pressure of the screws, while the latter is not convenient for disassembling the LCD screen, which increases the difficulty of maintenance and has high limitations in use;

[0004] Patent No. CN216957357U discloses a liquid crystal display module that avoids assembly damage, including a display panel and a PCB substrate, the display panel is arranged on the upper side of the PCB substrate, the upper surface of the PCB substrate is connected to a baffle, the baffles are respectively arranged on both sides of the display panel, the upper surface of the display panel is connected to a limit bar, the bottom surface of the limit bar is provided with a positioning column, and the limit bar is fixed to the display panel by the positioning column, the upper surface of the limit bar is connected to a flexible metal sheet, and the outside of the flexible metal sheet is arranged on the outside of the baffle, and the baffle is connected to the flexible metal sheet by bolts. The utility model realizes the rapid alignment and assembly of the display panel and the PCB substrate by arranging the positioning column in the positioning groove, and avoids the contact between the bolt and the display panel by arranging the bolt on the side, so that the display panel will not be damaged, and the yield rate of the display panel module during assembly is guaranteed. When the LCD display panel module of the above scheme is actually used, when the display panel and the limit strips are installed, the two groups of limit strips need to be respectively clamped on both sides of the display panel. Since the two groups of limit strips are independent, they are easy to loosen during the subsequent installation process, affecting the assembly efficiency of the display panel module. Therefore, we propose a LCD display panel module that avoids assembly damage. Utility Model Content

[0007] Preferably, a slot is provided on the top of the horizontal plate 1, and the slot is slidably connected to a sliding rod at one end of the horizontal plate 2. A spring 2 for limiting is glued to the side where the horizontal plate 1 and the horizontal plate 2 are close to each other, and a rubber strip is glued to the top of the horizontal plate 1 and the horizontal plate 2.

The horizontal plate 1 and the horizontal plate 2 are arranged between the limit strips at both ends. The slot on the surface of the horizontal plate 1 is slidably connected with the slide bar at one end of the horizontal plate 2, and the horizontal plate 1 and the horizontal plate 2 are elastically connected through the spring. When assembling the limit strip and the display panel, after the limit strip is clamped at both ends of the display panel, the spring 2 drives the horizontal plate 1 and the horizontal plate 2 to be close, and then the limit strip is clamped at both ends of the display panel, which is not easy to loosen, and the subsequent installation of the display module is convenient.
