Embodiment Construction
[0042] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0043] refer to figure 1 and figure 2 , the first aspect of the present invention relates to a light guide plate 100, the light guide plate 100 includes a light guide plate body 110, and the light guide plate 100 further includes at least a A plurality of first dots 111b, wherein the first dots 111b include a first transparent matrix (not shown in the figure) and first reflective particles (not shown in the figure) dispersed in the first transparent matrix. The first reflective particles have a first concentration, and the first concentration may be 5wt%, or 30wt%, or any value between the two. When the first reflective particles adopt different first concen...

The invention discloses a light guiding plate, a backlight source, a display device and a light guiding plate manufacturing method. The light guiding plate comprises a light guiding plate body and a plurality of first net dots which are at least positioned at a first preset position of a light emitting face of the light guiding plate body, each first net dot comprises a first transparent matrix and first light reflecting particles dispersed in the first transparent matrix, the first light reflecting particles have first concentration, and the first preset position is a dark zone position which is formed when a light source is incident on the light guiding plate body. The backlight source comprises the light guiding plate, and the display device comprises the backlight source. The light guiding plate manufacturing method comprises the following steps: the light guiding plate body is provided, the plurality of first net points are at least arranged at the first preset position of the light emitting face of the light guiding plate body, and the first light reflecting particles have the first concentration. Light emitting uniformity of the light emitting face can be realized via the light guiding plate.
Description
technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a light guide plate, a backlight source, a display device and a manufacturing method of the light guide plate. Background technique [0002] The light guide plate is used to convert the line light source emitted by the LED light source into a surface light source. Since each line light source has a fixed divergence angle, when the line light source irradiates the light guide plate, a dark area may be formed on the light guide plate. [0003] Therefore, how to eliminate the dark area formed on the light guide plate has become a technical problem to be solved urgently in this field. Contents of the invention [0004] The present invention aims to solve at least one of the technical problems existing in the prior art, and proposes a light guide plate, a backlight source, a display device and a manufacturing method of the light guide plate. [0005] The first aspec...
