Introduction

Light guide film: also known as backlight film, light guide film, LGF (Light Guide Film).

Applicable to: all kinds of luminous remote control, such as game console remote control, computer backlight board, password lock, automobile control panel and other fields.

Principle of light guide film

The light guide film is the leading domestic technology and has a tendency to replace the EL function. The light source is 1-4 LED lights. Through the principle of optical refraction, the button surface can emit light evenly and softly and can obtain high brightness. At the same time, the dark area can be adjusted during design. The light intensity can reach more than 100 chopped dela. Through the hot pressing process, the precise optical dots or microprism structure on the mold are copied to the surface of the PC film. The optical microstructure can effectively refract the light that is totally reflected into the PC film out of the surface of the PC film.

Advantages of light guide film

1. Low price;

2. Even light emission;

3. Diversified colors on the same plane;

4. Good stability and easy assembly;

5. Ultra-thin does not affect the feel; the thickness is 0.125MM.

Light guide film characteristics

1. The structure itself has no special requirements for the circuit part;

2. Good luminous effect, uniform brightness and high light intensity;

3. Good physical stability, abrasion resistance, and the service life of the product can reach more than 1 million times;

4. Combined with metal shrapnel conductive film, it does not affect the feel of Metal Dome;

5. Save LED lights and power consumption. Generally, only two LED lights are needed for the small area backlight of mobile phones;

6. Light weight, soft, thin thickness, thickness 0.125mm, used in mobile phones, different from the light guide plate will take up more space.
