According to the shape tablet: into the light guide plate from the point of view of a rectangular office. Wedge plate: also known as ramp, into the light point of view is from the side of the side of a thin to thick wedge (triangular) shape. Printed press outlets: LGP completed form after processing, in printed form will be printed on the reflective surface outlets, is divided into two kinds of IR and UV. Non-print style: light guide plate forming the network formed directly on the reflective surface. Divided into chemical etching (Etching), precision machinery characterization method (V-cut), optical lithography (Stamper), internal diffusion. Into the light into the light side according to formula: the light (lamp or LED) placed on the side of the light guide plate. Direct type: the light (lamp or LED) placed at the bottom of the light guide plate. Press molding Injection molding: injection molding machine application of optical grade PMMA particles using high-temperature, high-pressure coolant injection mold forming. Cutting Forming: The optical grade PMMA cutting process is completed after the original board finished.
