AI Technical Summary

Technical Problem

Insufficient mechanical strength of the backlight module leads to deformation, affecting the display effect of the LCD device.

Method used

A protrusion is provided on the back plate and a main groove is designed on the protrusion. The main groove extends in the same direction as the protrusion to enhance the mechanical strength of the back plate. Reinforcing materials such as plastic or graphene can be used to reinforce the structure.

Benefits of technology

The mechanical strength of the backlight module has been improved, the risk of deformation has been reduced, and the display effect has been improved.
