Line can again reflect into and recycle in light guide plate, controls light and penetrates from light guide plate front 32, from
And realize backlight effect.
Fig. 2 is existing display modular structure sectional view, its by frame before module, liquid-crystalline glasses 1, glue frame,
Blooming piece 2, light guide plate 3, reflector plate 4, light source 5 and backboard 6 form.Reflector plate 4 and light guide plate
3 are placed sequentially in backboard 6 cavity, and backboard 6 supports and partial appearance function as structure, this kind of knot
Structure is complicated, and complete machine thickness is thicker, relatively costly, it is impossible to reach the ultrathin design of display module.And carry on the back
Plate is generally metal or plastic parts, and its color is single, is difficult to make different appearance.
Summary of the invention
This utility model purpose is: providing a kind of composite light guiding plate structure, it does at the light guide plate back side and reflects
With the complex reflex layer of outward appearance one, the exiting surface at light guide plate increases light guide plate mesh point or micro structure sets
Meter, and utilize the rigidity of light guide plate to serve as structural support, it is possible not only to reduce optical loss and improve aobvious
Show module brightness and uniformity, and the use of backboard can be cancelled, to realize showing that the ultra-thin of module sets
Meter.
The technical solution of the utility model is: a kind of composite light guiding plate structure, including having incidence surface, going out
Bright finish and the light conducting plate body at the back side, the exiting surface of described light conducting plate body is evenly equipped with light guide plate mesh point or
Micro structure, the described light conducting plate body back side has complex reflex layer.
Preferably, described complex reflex layer from the back side of light conducting plate body outwards the most successively by optical bond layer,
Reflecting layer, outward appearance layer are constituted.Wherein, described optical bond layer is clear, viscous optical cement, described optics
The thickness of tack coat is more than 10um.Described reflecting layer is PET foaming layer.
The utility model has the advantages that:
1. this utility model increases light guide plate mesh point or microstructure design at the exiting surface of light guide plate, passes through
The optical reflection comprehensive function of site or the diffusion of micro structure and backside reflection sheet, can reduce optics
Loss and raising show module brightness and uniformity, and owing to site or micro structure are arranged in exiting surface,
Procedure for processing is similar with tradition PMMA light guide plate, and processing procedure is simple, and yield is high, reduces integral product
Cost, improves product competitiveness.
2. this utility model adds complex reflex layer at the back side of light conducting plate body, and utilizes light guide plate
Rigidity serve as structural support, complex reflex layer has a multiple structure, compatible reflection and outward appearance function,
Compare existing display module, because the use of composite light guide plate, the use of backboard can be cancelled, to realize
The ultrathin design of display module, it can be used for mobile phone, flat board, display and flat panel TV.
