Embodiment 1

[0047] Such as Figure 4 As shown, after passing through the deformable layer 7 , the outgoing light rays of the plurality of LEDs are all along a direction perpendicular to the light emitting surface of the light guide plate 1 , thereby realizing uniform illumination of the curved backlight module.

Embodiment 2

[0049] Such as Figure 5 As shown, after the outgoing light rays of the multiple LEDs 2 pass through the deformable layer 7 , the final outgoing light rays of the multiple LEDs 2 are all parallel, so as to realize the uniform illumination of the curved backlight module.

[0050] The embodiment of the present invention also provides a display module, wherein the display module includes a flexible display and the backlight module described in any one of the above, the flexible display 3 and the backlight module There is an air interlayer 4 at intervals, and the preferred implementation methods are as follows: Figure 6 and 7 shown.

[0051] When the flexible display screen 3 is deformed, the air spacer 4 will exert pressure on the shell layer 71 of the deformable layer 7 in the backlight assembly, and at the same time, due to the stress of the shell layer 71 itself, the shell layer 71 will exert pressure on the light deflection layer 72. The pressure causes the thickness of t...

Abstract

The invention provides a backlight module, a display module and a display device. The backlight module includes a plurality of backlight assemblies connected by elastic glue; each backlight assembly includes: a light guide plate; A plurality of light-emitting diodes LEDs on the light side; a deformable layer arranged on the light-emitting side of the light guide plate, the thickness of the deformable layer can be changed under the action of pressure, so as to adjust at least some of the LEDs in the plurality of LEDs. The original outgoing ray is deflected. The invention can realize the uniform illumination of the bent backlight module.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a backlight module, a display module and a display device. Background technique [0002] A flexible display is made of soft materials, a deformable and bendable display device, as thin as paper, and the content will not disappear even if the power is cut off, it is also called "electronic paper". At present, flexible display technology has received more and more attention. Researchers have devoted themselves to how to increase the curvature of flexible display devices or prolong the service life of flexible display devices. Some flat panel manufacturers have also developed flexible display products to attract consumers. look. [0003] The backlight module is one of the key components of the liquid crystal display, which provides brightness and light source for the liquid crystal display panel, so that the display panel displays images. Therefore, the quality of the light s...
