Light Guide Film

Light Guide Film (LGF）: A Key Component in Display Technology

Light Guide Film (LGF) is a transparent material used in backlight units for various display devices, including LCD TVs, computer monitors, and smartphones. It plays a crucial role in directing and diffusing light, ensuring a uniform and bright illumination on the screen.

Light guide film (LGF) The thickness is only 0.1mm ~ 0.5mm, and can be designed according to the customer’s organization. Through the surface microstructure, the side of the LED light is refracted to achieve illumination with the effect of uniform light.

Rayera’s LGF solution not only can provide complete microstructure layout planning, suggestions and arrangements of LEDs, but also provide complete light guide film assembly.

Key Features of LGF:

Light Transmission: LGF is highly transparent, allowing light to pass through efficiently.
Light Diffusion: LGFs are designed to scatter light evenly, ensuring a uniform illumination on the display.
Flexibility: LGFs are often flexible, making them suitable for various display designs.
Durability: LGFs are durable and can withstand harsh environmental conditions.

Types of LGF:

Edge-Lit LGFs: Light enters the LGF from the edges and is guided throughout the material.
Surface-Lit LGPs: Light enters the LGF from the top surface and is diffused throughout the material.
Dot-Matrix LGPs: LGPs with a pattern of dots or lenses that control the light distribution.

Applications of LGF:

LCD Displays: Backlighting for LCD TVs, computer monitors, and laptops.
LED Displays: Providing uniform illumination for LED signs and displays.
Automotive Lighting: Used in dashboards and other interior lighting applications.
Medical Devices: Backlighting for medical imaging equipment and displays.

Benefits of Using LGF:

Improved Brightness: LGFs can enhance the brightness and uniformity of displays.
Energy Efficiency: They can reduce energy consumption by efficiently directing light.
Thin Design: LGFs enable the creation of thinner and more compact devices.
Versatility: LGFs can be used in a wide range of applications.
