Just, the big one camera light guide plate of compatible strong, multi-orientation detection, detection range detects jig.
Background technique
Light guide plate (light guide plate) is acrylic/PC plate material using optical grade, then high anti-with having
Rate and the not hitech materials of extinction are penetrated, stamps light guiding points with UV screen printing technology in the acryl plates bottom surface of optical grade.
The light that issues from lamp is drawn in the stop on optical grade acryl plates surface, when light is mapped to using optical grade acryl plates
When each light guiding points, reflected light can be spread toward all angles, then destroyed conditioned reflex and projected by light guide plate front.By various
Density, light guiding points not of uniform size, can make light guide plate uniformly light-emitting.
Since light guide plate is one of the Primary Component in LED backlight field, technology content is also higher, generally by the factory of profession
Family's production, and strict inspection is had to pass through before the light guide plate factory sold.Conventional method is that light guide plate is installed to backlight mould
In group, whether there is by the backlight module that light guide plate is assembled in different directions and angular observation because light guide plate shape and structure is abnormal or
Shadow, speck situation caused by light guide plate surface scratches after detection, are needed again to dismantle light guide plate from backlight module and are taken
Out.The slightly larger light guide plate of size, be installed to backlight module and from backlight module disassembly take out time-consuming and laborious, and installing and dismounting mistake
Cheng Rongyi causes the damages such as scuffing abnormal light guide plate.In addition, size it is slightly larger backlight module multi-angle inspection manual overturning it is polygonal
It is larger to spend detection difficulty.
