Embodiment 1
[0044] Such as figure 1 As shown, the present invention provides a display device, including a display panel 100 . The display panel 100 includes: a backlight module 1 , a liquid crystal display 2 , a cover 3 , a photosensitive hole 4 and a first baffle 5 .
[0045] Wherein the backlight module 1 is divided into a direct-type backlight module and an edge-type backlight module according to different distribution positions of light sources. This embodiment is preferably a side-type backlight module. The backlight module 1 includes: a bottom plate 11 , a reflection sheet 12 , a light guide plate 13 , an optical film 14 , a plastic frame 15 , a light source 16 , and a light-shielding film 17 .
[0046] The reflective sheet 12 is disposed on the bottom plate 11 and is mainly used to reflect the light exposed at the bottom of the light guide plate 13 into the light guide plate 13 to improve the utilization rate of the light.
[0047] The light guide plate 13 is arranged on the re...
Embodiment 2
[0059] Such as figure 2 As shown, this embodiment includes most of the technical features of Embodiment 1. The difference between this embodiment and Embodiment 1 is that in this embodiment, the first baffle 5 is made of a light-transmitting material, and the first baffle 5 A light-shielding layer 6 is arranged on one side surface;
[0060] In this embodiment, the material of the first baffle 5 is preferably glass. The first baffle 5 can be detachably connected to the cover 3 , or can be connected to the cover 3 in an integrated manner.
[0061] In this embodiment, the light-shielding layer 6 is disposed on the side surface of the first baffle plate 5 facing the backlight module 1 . Wherein the light-shielding layer 6 is made of an opaque material, and light-shielding ink is preferred in this embodiment. The light-shielding layer 6 formed by the light-shielding ink prevents the light in the backlight module 1 from entering the photosensitive hole 4 and interferes with the ...
Embodiment 3
[0063] Such as image 3 As shown, this embodiment includes most of the technical features of Embodiment 2. The difference between this embodiment and Embodiment 2 is that: in this embodiment, a light-shielding tape 7 is set on one side surface of the first baffle plate; 2, a light-shielding layer 6 is provided on one side surface of the first baffle 5.
[0064] In this embodiment, the light-shielding tape 7 is disposed on the side surface of the first baffle 5 facing the backlight module 1 . The light-shielding tape 7 is used to prevent the light in the backlight module 1 from entering the photosensitive hole 4 and interfering with the infrared light and external light received in the photosensitive hole 4 to affect the function of the photosensitive hole 4 . In other embodiments, the light-shielding tape 7 can also be disposed on the surface of the first bezel 5 away from the backlight module 1 or the light-shielding tape 7 is disposed on both sides of the first bezel 5 at t...
