The industries such as mobile phone, panel computer, GPS, solaode, locate industry-leading level, company's multimachine combination
Automatic coating production line realizes full automation and produces, and can be the client direct labor that saves more than 80%, for looking forward to
Industry realizes recruitment cost is greatly lowered, and provides a whole set of technological process of production being suitable for for enterprise and produces solution
Certainly scheme.In backlight source module, most crucial technology is the optical technology of light guide plate, mainly has printing shape and injection
Two kinds of light guide plate forms of molding shape, other adds printing, laser dotting such as ejection formation, corrosion etc. account for seldom than
Example, is not suitable for producing principle in batches.Printing shape is because its low cost became main flow skill within the long period in past
Art, but the highest always its major defect of certified products, and the light conducting plate structure that LCD product requirement is more accurate,
Ejection formation shape light guide plate necessarily becomes backlight Developing mainstream, but a corresponding Tool and Die Technology difficult problem is the most Japanese
The big factory of minority can overcome.
Existing backlight uses common laminating pattern due to reflector plate and light guide plate, in transport for a long time
Middle meeting, because friction causes light guide plate to be ground flower, affects translucent effect, makes troubles to use.
Based on above reason, new backlight is needed to be devised, by arranging salient point on reflector plate,
The contact of change face is point cantact, reduces the friction between light guide plate and reflector plate, improves translucent effect, i.e. a kind of
Backlight.
