Abstract
The present invention provides a light guide plate, a backlight module, and a display device. The light guide plate contains a platform of uniform thickness along an edge of the light guide plate for installing a flexible printed circuit (FPC). The platform contains a plurality of through openings for installing light emitting diodes (LEDs). The backlight module contains LEDs, a FPC, and the light guide plate. The FPC is configured on the platform. The LEDs are configured inside the openings. The display device contains the backlight module. The present invention enhances the reliable connection between the FPC and light guide plate, reduces the probability of coupling failure, and lower the manufacturing difficulty and cost.
