Showing device eliminates the setting of prior art dorsulum, breaks through the feelings for reducing display device part thickness not obtaining material
Under condition, the thickness of display device is created a further reduction.
Detailed description of the invention
Fig. 1 is the sectional view of display device preferred embodiment in the utility model.
Fig. 2 is the sectional view of display device preferred embodiment in the utility model.
Fig. 3 is the sectional view of display device another preferred embodiment in the utility model.
Specific embodiment
The utility model provides a kind of display device, to keep the purpose of this utility model, technical solution and effect more clear
Chu defines, and referring to the drawings and gives an actual example to the utility model further description.It should be appreciated that described herein
Specific embodiment is only used to explain the utility model, is not used to limit the utility model.
As shown in Figures 2 and 3, display device provided by the utility model includes: screen 100, the optics set gradually
Diaphragm 200, guide-lighting backboard 300 and reflectance coating 400.
The leaded light backboard 300 has the function of light guide plate and backboard in conventional display device simultaneously, saves making for backboard
With, reduce display device thickness while, reduce its cost.It is preferred that the leaded light backboard 300 selects optical grade first
Acrylic/PC plate material；Then with having high reflectivity and the not material of extinction, in acrylic/PC plate material bottom surface of optical grade
Light guiding points are stamped with UV screen printing technology to be made.
The special optical and physical characteristic of organic glass is dexterously utilized in the utility model, pursues current industry level
It is ultimate attainment ultra-thin, traditional light guide plate and backboard are integrated, limited structure space is further utilized.
In the utility model further preferred embodiment, the display device further include: center 500, the center
500 longitudinal section is in concave character type；That is, 500 structure of center in the utility model is relatively simple, no setting is required and backboard
The structures such as connecting groove, connecting hole, only need to be Nian Jie with guide-lighting backboard 300, this is and the completely different place of the prior art.
In ground of the invention preferred embodiment, fixation is formed between the center 500, guide-lighting backboard 300 and screen 100
The optimum position of envelope screen glue-line 600, the fixed envelope screen glue-line 600 is as shown in Figure 2.Comparison diagram 1 and Fig. 2 are it is found that traditional is aobvious
Showing device envelope screen glue-line 70 is only arranged between center 60 and screen 10, center 60 and backboard 50 need through buckle and/or
