Embodiment 1

[0027] First, through figure 2 , the edge-type backlight module according to Embodiment 1 of the present invention will be described. An edge-type backlight module includes an LED light source 10 and an optical film set 11 . The optical film set 11 includes a light guide plate 13 arranged on one side of the LED light source, a prism sheet 14 arranged above the light guide plate 13, and a reflective sheet 12 arranged below the light guide plate 13; wherein, the An optical diffusion unit 20 is arranged on the optical film group 11 , and the density of the optical diffusion unit 20 at the end close to the LED light source 10 is higher than that at the end far from the LED light source 10 . The optical diffusion unit 20 is disposed on the light emitting surface of the reflection sheet 12 .

[0028] The side-entry backlight module of this embodiment does not need to be provided with a diffusion sheet, and the optical diffusion unit 20 replaces the uniformity of the light output ...

Embodiment 2

[0033] Please refer to image 3 , is an exploded view of the edge-type backlight module according to Embodiment 2 of the present invention. Only the differences between Embodiment 2 and Embodiment 1 will be described below, and the similarities will not be repeated here.

[0034] The optical diffusion unit 20 is also disposed on the light emitting surface of the light guide plate 13 .

Embodiment 3

[0036] Only the differences between Embodiment 3 and Embodiment 2 will be described below, and the similarities will not be repeated here.

[0037] The optical diffusion unit 20 is also disposed on the light incident surface of the prism sheet 14 . The prism sheet optical diffusion unit 20 can prevent the adsorption of the prism sheet and the light guide plate, and reduce the generation of Newton's rings of visible light and infrared light.

[0038] Here, alternatively or additionally, the optical diffusion unit 20 may be further disposed on the light exit surface of the prism sheet 14 or the light entrance surface of the light guide plate 13 .

Abstract

The invention discloses a side-entry backlight module and electronic equipment thereof. The side-entry backlight module comprises an LED light source and an optical film group. The optical film group comprises a light guide plate arranged on one side of the LED light source, a prismatic lens arranged above the light guide plate and a reflector plate arranged below the light guide plate; and an optical diffusion unit is arranged on the optical film group, and the density of the optical diffusion unit at the end close to the LED light source is higher than that of the optical diffusion unit at the end far away from the LED light source. The invention provides an ultrathin display device with a high dynamic contrast.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a side-entry backlight module and electronic equipment. Background technique [0002] Edge-lit backlight modules are widely used commercially in liquid crystal displays. In recent years, in order to improve the contrast of the liquid crystal display and improve the problem of liquid crystal dynamic smear, a high-dynamic contrast (High-Dynamic Range, HDR) technology has emerged. HDR technology can increase the brightness range, improve the contrast of the brightest and darkest pictures, not only obtain a wider color range, but also bring darker or whiter color effects, so that users can see more picture details, greatly improving display effect. HDR technology refers to dividing the backlight into multiple areas according to a certain direction, each area is called a block (Block), each area is rectangular, and the liquid crystal display is also divided into multiple area...
