AI Technical Summary
The uneven brightness in the edge areas of the monitor's backlight module results in uneven brightness across the entire screen.
By adjusting the spacing between the second LED beads in the end light-emitting light group to make its density higher than that in the middle area, the number of light emitted is increased to compensate for the edge brightness. A top block is set between the light guide plate and the LED beads to protect the LED beads. Heat shrink tubing and insulating adhesive layer are used to improve the connection reliability.
It improves the edge brightness of the display backlight module, ensures overall brightness uniformity, and protects the LED beads from damage.
