Example Embodiment

[0020] Example 1

[0021] A light guide plate with a hole structure, the structure diagram of the light guide plate with a hole structure in this embodiment is as follows figure 1 As shown, the light guide plate body 1 and the light guide point 2 are included; the material of the light guide plate body 1 is iron. In the backlight source with the light guide plate, the bottom end is the light source incident direction, which corresponds to the light source installation position 4. The installation position 4 is equipped with an LED light strip 5 as a light source; the light guide point 2 is a light reflection microstructure distributed on the light guide plate body 1; a through hole 3 is opened on the top of the light guide plate body 1 near the edge;

[0022] Among them, such as figure 2 As shown, the through hole 3 is a circular through hole, and the position of the through hole 3 is located at the left side of the top end of the light guide plate body 1 near the edge.

Example Embodiment

[0024] Example 2

[0025] A light guide plate with a hole structure, such as image 3 As shown, on the side opposite to the light source of the through hole 3, the light guide points 2 are densely distributed, specifically: the distribution density of the light guide points 2 is greater than the distribution density of the light guide points 2 at any other position on the light guide plate body 1.

[0026] In this embodiment, the distribution of light guide points is adjusted near the edge of the perforated structure of the light guide plate, and the light guide point distribution rule near the opening position is adjusted to increase the light guide point density on the opposite side of the perforated light source, so that The overall light-emitting brightness of the light guide plate is uniform, so that the light-emitting effect at the opening is consistent with the light-emitting effect of the overall light guide plate, which can meet the requirements of high proportion of mobil...

Abstract

The invention discloses a light guide plate with a hole structure. The light guide plate comprises a light guide plate body (1) and light guide spots (2); the bottom end of the light guide plate body(1) is an incident azimuth of a light source; the light guide spots (2) are of light reflection micro-structures distributed on the light guide plate body (1); and the top of the light guide plate body (1) near an edge is provided with a through hole (3). The light guide plate with the hole structure can cause a display screen of a mobile phone to break through the limit of a front camera, so thatthe display screen of the mobile phone can be provided with an ultra-narrow frame or be frameless; meanwhile, the density of the light guide spots on an opposite side of a light source at the hole isimproved through the adjustment of a distribution law of the light guide spots near the hole position, so that the overall luminance of the light guide plate is uniform, facilitating the light effectat the hole consistent with that of the overall light guide plate.

Description

technical field [0001] The invention relates to the technical field of light guide plates, in particular to a light guide plate with a hole structure. Background technique [0002] With the continuous change of the shape of the smartphone, in order to obtain a larger viewing area, the screen of the mobile phone is continuously enlarged to the edge of the mobile phone. Due to the structural limitation of the front camera lens, the backlight of the previous mobile phone was shortened to avoid the position of the camera. [0003] However, shortening the length of the backlight is not conducive to the full-screen effect of the mobile phone. Therefore, by setting a hole in the corresponding position of the backlight to place the camera, the display of the mobile phone can be extended to the edge of the mobile phone, and it can be designed as an ultra-narrow bezel or a bezel-less mobile phone. The light guide plate also needs to be provided with corresponding openings. At the sa...
