Light guide plate and backlight module

Abstract

The invention discloses a light guide plate and a backlight module. The light guide plate is provided with a light-emitting surface, a bottom surface, a first incident light surface and a second incident light surface, wherein the bottom surface opposite to the light-emitting surface gradually closes to the light-emitting surface along a first direction far away from the first incident light surface and a second direction far away from the second incident light surface or gradually keeps away from the light-emitting surface along the first direction and the second direction; the first incident light surface and the second incident light surface are connected with the light-emitting surface and the bottom surface and are opposite to each other; the light guide plate comprises a plurality of first recess parts and second recess parts, which are configured on the light-emitting surface, wherein the first recess parts are online arrayed on a first shaft, the second recess parts are online arrayed on a second shaft, the first shaft line is parallel and adjacent to the second shaft line, the first shaft line is perpendicular to the first incident light surface and the second incident light surface, and the second recess parts are formed on a plurality of orthographic projections online formed on the first shaft and are alternately arrayed with the first recess parts.

Description

technical field [0001] The present invention relates to a backlight module, and in particular to a light guide plate suitable for the backlight module. Background technique [0002] With the advancement of technology, computers have become an indispensable tool in our daily life. At present, most of the computers on the market are of standardized standard design, so some manufacturers have made breakthroughs in this unchanging computer product, such as adding a manufacturer’s logo (mark) to the surface of the computer casing (casing) to enhance the additional value of the product. value. Since the logo is only formed on the housing by drawing or engraving, a backlight module is arranged in the housing and corresponding to the position of the logo to illuminate the logo so that the logo can be displayed. [0003] Please refer to figure 1 , which shows a schematic side view of a known backlight module. The known backlight module 1 includes a light guide plate 10 and two li...

Problems solved by technology

However, the light will produce total reflection on the light-emitting surface 12

Therefore, it is known that the light emitting brightness of the light emitting surface 12 of the known light guide plate 10 is uneven and the light emitting intensity of the light emitting surface 12 is insufficient, which affects the display effect of the logo.

[0005] At present, the way to solve the above shortcomings is to attach a diffuser (not shown) on the light-emitting surface 12 or to form a diffusing agent on the light-emitting surface 12 to solve the problem of uneven light brightness, and to arrange a reflective sheet (not shown) under the bottom surface 14. Shown) to solve the problem of insufficient light intensity

However, the manufacturing cost of the known backlight module 1 as a whole is relatively high
