Problems solved by technology

[0005] The cost of LED light bars is relatively expensive, and often due to factors such as the pitch (pitch) value of the LEDs in the LED light bar, the distance from the light-emitting surface of the light guide plate to the LED light bar, etc., problems such as hot spot (hot spot effect) and optical uniformity difference are caused.
In addition, since the light guide plate needs to maintain a proper distance from the LED light bar, it is very difficult to make a curved TV.

Abstract

The invention discloses a backlight module, which comprises a light guide plate, wherein a surface light source is arranged on at least one surface of the light guide plate. The invention also discloses a manufacturing method of the backlight module and a display device. The backlight module, the manufacturing method of the backlight module and the display device provided by the invention have theadvantage that the display performance can be improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight module, a manufacturing method thereof, and a display device. Background technique [0002] Such as figure 1 Shown is a schematic structural diagram of a liquid crystal module in the prior art. A liquid crystal module in the prior art generally includes a front frame 11 , a liquid crystal panel 12 , a plastic frame 13 , an LED light bar 14 , a light guide plate 15 and a back plate 16 . [0003] Such as figure 1 As shown, the existing liquid crystal module usually adopts a side-type backlight source, and provides brightness through a packaged LED light bar 14 . The LED light bar 14 is attached to the back plate 16 , and the emitted light is totally reflected by the light guide plate 15 and propagates forward. When encountering the dots on the light guide plate 15, the total reflection of the light will be destroyed, and then spread on the surface of the light guid...
