Embodiment Construction

[0023] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0024] see figure 1 The present invention provides a light guide plate 10 , which is provided with a double-sided reflective layer 12 , and the double-sided reflective layer 12 divides the light-emitting surface of the light guide plate 12 into two partitions 14 . In this embodiment, the areas of the two partitions 14 are equal.

[0025] The two partitions 14 are the first light guide portion 140 and the second light guide portion 150 respectively. The double-sided reflective layer 12 is pasted between the first light guide portion 140 and the second light guide portion 150 . In this embodiment, the double-sided reflective layer 12 is pasted on the first side 142 of the first light guide portion 140 by double-sided tape, and the first side 152 of the second light guide portion 150 is pasted on the double-sided reflective layer 12 and located on the f...

Abstract

The invention provides a light guide plate, and the light guide plate is provided with at least one two-side reflection layer. The two-side reflection layer enables a light outgoing surface of the light guide plate to be divided into a plurality of regions. Through the above mode, the light guide plate achieves the brightness partitioning and regional brightness independent control of a side-incoming type backlight module group, so as to achieve higher light isolation degree at lower cost. Moreover, the light guide plate can effectively reduce the power consumption of the liquid crystal display and prolongs the standby time and service life of the mobile terminal. The invention also provides the side-incoming type backlight module group, the liquid crystal display and a mobile terminal, which all employs the light guide plate.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to the design of a light guide plate in an edge-type backlight module, and also relates to a liquid crystal display and a mobile terminal equipped with the edge-type backlight module. Background technique [0002] Liquid Crystal Display (LCD, Liquid Crystal Display) has many advantages such as thin body and no radiation, and has been widely used. Most of the liquid crystal display devices on the current market are backlight type liquid crystal display devices, which include a liquid crystal panel and a backlight module (Backlight Module). Since the liquid crystal panel itself does not emit light, it needs to use the light source provided by the backlight module to display images normally. Therefore, the backlight module has become one of the key components of the liquid crystal display device. [0003] The backlight modules are classified into two types: edge-lit backlight mod...
