Abstract

The invention provides a light guide plate and a display device thereof, wherein a plurality of hangers are provided below the light guide plate, a plurality of hanging holes are provided around the light guide plate, and the light guide plate is elastic. The invention also provides a display device using the light guide plate. The light guide plate material and the display device provided by theinvention can greatly reduce the use of the light guide plate material, and the light guide plate will not change in size when heated because certain tensile stress has been preset, thereby solving the optical problems caused by thermal expansion and reducing the cost of LCD TV.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a light guide plate and a display device thereof. Background technique [0002] At present, with the development of LCD TV technology, the size continues to increase, the cost of materials continues to rise, and the process difficulty is getting higher and higher. [0003] Liquid crystal display devices need to use backlight modules and liquid crystal panels. Some optical films need to be used in the backlight modules. Such optical films can play the role of fogging and brightening. , the optical diaphragm needs to be positioned. In the prior art, the optical diaphragm is positioned on the middle frame or the back plate, and the most common positioning method is leaning positioning, that is, lugs are set on the optical diaphragm, and the middle Positioning grooves are set on the frame or back plate, the lugs are limited in the positioning grooves, and tapes are attached to prev...
