Embodiment Construction

[0017] The content of the present invention will be further described below in conjunction with the accompanying drawings and preferred specific embodiments of the present invention. The examples given are only for explaining the present invention, not for limiting the scope of the present invention.

[0018] like Figure 1 to Figure 3 As shown in , this solution is an LCD backlight display effect optimization structure, including a light guide plate 1, a light source 2 and a reflective sheet 3, the reflective sheet is set on the back of the light guide plate 1, and the light source 2 is set on the light guide plate 1 corresponding to On the two parallel sides, the reflection sheet 3 is provided with grooves 4 , and the grooves 4 are arranged at both ends of the two sides where the reflection sheet 3 intersects with the light source 2 side of the light guide plate 1 . The groove 4 described in this solution is rectangular. Certainly also can adopt other can reach other shape...

Abstract

The invention relates to an LCD backlight display effect optimized structure, and belongs to the technical field of electronic products. The LCD backlight display effect optimized structure comprises a light guide plate, light sources and a reflective sheet. The reflective sheet is arranged on the back face of the light guide plate, the light sources are arranged on the two correspondingly-parallel sides of the light guide plate, grooves are formed in the reflective sheet, and the grooves are formed in the two ends of the two intersecting sides of the reflective sheet and the light source sides of the light guide plate. According to the LCD backlight display effect optimized structure, the phenomenon that uneven display happens to the sides close to the light sources under a white display picture of an LCD, namely different degrees of hot spots occur can be avoided fundamentally and thoroughly, the production cost of products can also be lowered, the percent of pass of the products is improved gradually, and more importantly, the LCD effect is made to be more perfect.

Description

technical field [0001] The invention relates to an LCD backlight display structure, in particular to an LCD backlight display effect optimization structure. Background technique [0002] Under the white display screen of the existing LCD, the phenomenon of display unevenness occurs on the side close to the light source, that is, bright spots of different degrees appear. Specifically, when the LCD is placed in a dark room, it is not difficult to see that the bright edge on the side of the light source is obvious. The optical principle: the light guide plate has the function of guiding and concentrating light. The light that comes out is guided to the surroundings through the light guide plate. When the light reaches the edge of the light guide plate, part of the light is refracted by the edge of the light guide plate and reaches the inner side of the plastic frame. The material of the plastic frame is PC white (strong reflectivity), and then refracted out The light is reflec...
