Metal Dome Array with Light Guide Film (LGF) & Light Shielding Film
- LGF is a transparent thin film with high refractive index and light transmittance, featuring surface microstructures of varying densities.
- LGF utilizes the phenomenon of total internal reflection due to differences in refractive index between media, guiding light rays to emit from the surface through the disruption of microstructures.
- LGF is a low-cost and low-energy-consumption light-conducting material.
1. It produces excellent luminous effects with uniform brightness and high light intensity.
2. It is lightweight, flexible, and thin, with a thickness of 0.125mm, making it suitable for use in mobile phones without occupying significant space compared to light guide plates.
3. It saves LED lights, reduces power consumption, and cuts costs.
4. Its structure does not have special requirements for circuit components.
Light Guide Film (LGF), also known as LGP (Light Guide Plate), is characterized by its ultra-thin profile, uniform illumination, and versatile color display. It is primarily used in mobile phone keypads, serving as a product that converts the point light source of LEDs into a surface light source through colored LGF. LGF is applied onto existing double-layer or EMI structure conductive films to achieve optimal light distribution.
The working principle of LGF involves utilizing the principles of light reflection and refraction, combined with specialized optical software design. Microstructure processing is applied to the optical fiber film, enlarging the "point light source" into a "surface light source." Light beams propagate from the medium at suitable angles and densities, resulting in excellent uniform illumination.
The design of LGF conductive film/LGP can reduce the need for several LED lights, addressing issues such as uneven brightness distribution, high power consumption, large space occupancy, and high costs.
