AI Technical Summary
The existing automotive module has an increased module thickness due to the space between the light guide plate and the LCD using a plastic frame, which leads to an increase in the bezel width. At the same time, the plastic frame fixing method is prone to loosening and making noise, affecting the performance and stability.
The light guide plate with an irregular design and the extended wall component wrapping film are fixed to the bottom of the iron frame by the first double-sided adhesive. The top is covered by light-blocking foam and the cover plate is fixed by the second double-sided adhesive. The backlight iron frame extends to the cover plate and is bent at 90 degrees for a stable connection.
The reduced space occupied by the plastic frame makes the module more compact, reduces abnormal noise, lowers costs, and improves the module's aesthetics and stability.

Backlight module usually includes shading bubble cotton, glue frame, light guide plate, iron stand and the like structural members. Due to the particularity of the vehicle-mounted environment, the weight of the light guide plate is relatively large, and therefore the light guide plate adopts a rear-mounted structure and is fixed on the LCD module through the buckling of the iron stand and the glue frame. Although this rear-mounted structure stabilizes the installation effect of the module, it also brings the following problems: first, a certain glue frame separation space (such as Figure 1 ) is formed between the light guide plate and the LCD, increasing the thickness of the module; second, since the backlight glue frame and the cover plate need to be fixed through double-sided adhesive, this fixing method needs to meet certain installation width requirements, thereby increasing the overall frame width of the module; finally, the buckling method of the light guide plate and the glue frame is prone to looseness or abnormal noise during actual installation, affecting the use effect and stability of the module.
