Classification Of Light Guide Plate

As the name suggests, the main function of the light guide plate is to guide the light to the direction required by the designer. All the light guide plates are designed to meet the needs of downstream products LCD and backlight modules. The most important thing is to achieve brightness and uniformity. Spend.

   Generally speaking, light guide plates have different classifications due to their shapes, production methods and functions, and there is currently no unified classification. After sorting:

1. According to the shape, it is divided into: flat plate and wedge plate (inclined plate)

    Flat plate: the light guide plate is rectangular when viewed from the light incident

    Wedge-shaped plate: From the point of light incident, one side is thick and the other side is thin and wedge-shaped (triangular) shape

2. According to the method of dot production: printed and non-printed

    Printing: After the light guide plate is processed, the dots are printed on the reflective surface by printing, and it is divided into two types: IR and UV

    Non-printing type: The dots are directly formed on the reflective surface when the light guide plate is formed. It is divided into chemical etching (Etching), precision mechanical characterization (V-cut), photolithography (Stamper), internal diffusion

3. According to the light input method: side light (tube and LED) and direct light

    Side-light type: place the luminous body (tube or LED) on the side of the light guide plate

    Direct type: place the luminous body (tube or LED) under the light guide plate
