AI Technical Summary
In the existing backlight display module, the retaining wall formed by extending the corners of the iron frame in the vertical direction is close to the liquid crystal display glass, which easily leads to bumping and cracking of the edges and corners of the liquid crystal display glass when assembled.
A backlight display module is designed to set a hollow port at the R corner of the central iron frame and communicate with the grooves of the shell to increase the moving space at the corners of the screen glass plate to avoid cracking. At the same time, through the design of bent parts and colloids, the moving space on the sides of the central iron frame is limited, and the overall strength and stability of the central iron frame are improved.
It effectively prevents the edges and corners of the liquid crystal display glass due to assembly deviation, and at the same time improves the strength and stability of the iron frame, making it more firmly fixed to the shell.
