Abstract

An exemplary backlight module ( 2 ) includes a light guide plate ( 23 ), a light source ( 25 ), a light source driver ( 27 ), and a frame ( 21 ). The light source is provided adjacent to the light guide plate. The light source driver is directly connected with the light source. The frame includes an upper frame ( 211 ) and a lower frame ( 212 ). The upper frame and the lower frame cooperatively form a space to accommodate the light guide plate, the light source, and the light source driver.

Claims (22)

1. A backlight module comprising:

a light guide plate;

a light source provided adjacent to the light guide plate;

a light source driver connected with the light source;

a frame comprising an upper frame and a lower frame, the frame forming a space to entirely accommodate the light guide plate, the light source, and the light source driver;

a flexible printed circuit, the light source driver being provided on the flexible printed circuit; and

a connector provided outside the frame, the connector being electrically connected with the light source driver via the flexible printed circuit.

2. A backlight module comprising:
