The type of the light guide plate Character LCD Modules

Scattered light guide plate-type printing 20x2 lcd display
The traditional scattered light guide underside printing white shades (gradation) outlets scattered incident light, scattered light shades depending on the diameter of the dot density. Outlets from the UV adhesive material is titanium dioxide, barium sulfide mixed viscous liquid of the composition. Figure 3 shows the dot diameter of the light source is incident end is 250μm, which is away from the light source side end edge of the light guide plate dot diameter 1250μm. Use outlets scattered light emitted from the light guide surface, some of evasion from the light guide plate and the bottom side of the light guide plate is returned to being reflective film reflective light guide plate to the surrounding light guide. Located in front of the light guide plate diffusion film has two functions, namely the incident spread to the set of optical prism diaphragm; Another function is to dampen the surface of the light guide plate dot shape. Diffusion film-shaped top of the first sheet set of triangular cross-section prism film and the cold cathode fluorescent lamp at a right angle direction (y direction), the second prism sheet set and then the diaphragm at right angles to the laying of the first sheet, by the This special design closure xy direction of the light guide plate surface again while desalination dot shape and unique wedge-shaped light guide cross onyx (gray stripes).
Injection Molding scattered light guide
The specific method is the use of injection molding precision etching technology microfabrication mandrel into the dot shape, re-use plastic injection molding machine manufacture light guide. 40x2 lcd
Reflective Injection molding LGP
It is the use of ultra-precision processing technology in the production of micro-optics light guide plate bottom mirror reflection of light within the light guide plate, this approach may be due to the production method makes scattered due to disappear. Specific production step is injection-molded into a mold core microfabrication oblong micro-reflecting mirror surface (Micro Reflector; hereinafter referred to as MR device), and then making use of the light guide plate plastic injection molding machine, MR system located in the bottom guide plate of the guide light board is formed integrally
