Position is accommodated to 9022 lower part of accommodation groove；The quantum dot membrane material 60, expansion tabula rasa 70 and the isolated protective layer being laminated
80 can be limited receiving to 9022 top of accommodation groove, and by the 110 phase pressing of liquid crystal display panel.
Then, then make internal component stationarity of the present invention good and installation stability is good, so that each internal component will not
Displacement loosens, and each internal component is while mounting structure is compact, but also display device provided by the present invention 2000 is whole
Body compact structure is exquisite and avoids the waste of material.
Meanwhile in the specific implementation, 901 outer wall of metal shell offers the line excessively of the perforation accommodation groove 9022
The strip PCB circuit board 10 is preferably closed in slot 9011, the position of the crossed beam trunking 9011, so that extremely convenient for outer signal line
The strip PCB circuit board 10, after the crossed beam trunking 9011 outer signal line to the strip PCB circuit board 10,
Liquid glue can be used to block the crossed beam trunking 9011, to enable the invention to effectively accomplish light leakage.
In turn, using effect of the invention can reach best.
Other embodiments etc., illustrate one by one here, not doing then.
In conclusion overall structure of the present invention is simple, easily implement, easy to operate, practical, specificity is strong, manufacturing cost
It is low, in structure improvement and technological improvement, do not need to increase too many cost, so that the present invention necessarily has good market
Promotional value, the present invention can be very welcome, can effectively be popularized.
