Embodiment Construction

[0019] refer to figure 1 , figure 1 It is a schematic structural diagram of an embodiment of the backlight module of the present invention. In this embodiment, the backlight module 100 includes a circuit board 11 , a light bar 12 , a light guide plate 13 and a double-sided adhesive tape 14 for the light guide plate.

[0020] The backlight module 100 is used in the display module, and is mainly used to provide a light source, wherein the circuit board 11 is not used to provide a light source, but to carry the light bar 12 and the light guide plate 13, and its own function is to support the display module. Perform signal control.

[0021] In this embodiment, the light bar 12 is an LED light source, which is composed of a plurality of LED lamp particles, the emitted light enters the light guide plate 13 , and then the light guide plate 13 provides uniform light. During this process, the ratio between the light entering the light guide plate 13 and the light emitted by the light...

Abstract

The invention discloses a backlight module and a display module. The backlight module comprises a circuit board, a lamp bar, a light guide plate and a light guide plate double-faced adhesive tape, wherein the circuit board comprises a first region for arranging the lamp bar and a second region connected with the light guide plate; the lamp bar is mounted on the front surface of the first region of the circuit board; the double-faced adhesive tape is arranged on the front surface of the second region and is used for connecting the circuit board with the light guide plate; and the front surface of the first region and the front surface of the second region are arranged in a step shape, so that one side, mounted on the circuit board, of the lamp bar is leveled with one side, connected to the circuit board, of the light guide plate. The backlight module disclosed by the invention has relatively high light coupling efficiency.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight module and a display module. Background technique [0002] A widely used display device is mainly composed of a display panel and a backlight module. The backlight module provides backlight for the display panel, and the backlight module mainly includes a light bar and a light guide plate. The light emitted by the light bar enters the light guide plate, and the uniform light emitted by the light guide plate is provided to the display panel. The light coupling efficiency between the light bar and the light guide plate reflects the utilization rate of light energy and affects the brightness of the backlight. Nowadays, more and more researches are carried out in the direction of improving the light coupling efficiency. [0003] In the current backlight module, due to structural limitations, the light incident surface of the light guide plate cannot completely cover th...
