About Light Diffuser sheet/film

UVTPC-DI Light Diffuser is made of polycarbonate plastic, the thickness is from 0.06mm to 5mm, and the light transmittance is from 40% to 85%, the surfaces can be smooth, matt, frosted, etc. It is also known as “LED Light Diffuser“, “Polycarbonate Diffuser“ and “Diffuser Film”. It can diffuse luminance coming from the light source, make energy efficiency higher, and make beautiful screens without luminance unevenness.

Light Diffuser panels are mainly used in the automobile industry, for example, Car Monitors, head-up displays (HUD), and some covers of LED light. It is also used as the covers of downlights, panel lights, advertisement billboards, the light covers of the printed circuit board, office lamps, kitchen lights, and fluorescent lights.

UVTECO is a leading supplier of Light Diffuser panels/films in China, which are made of Polycarbonate plastic, and thicknesses from 0.06mm to 5mm. Meantime, we provide machining services, including cutting, printing, routing, thermal forming, etc.

Frequently Asked Questions about light diffuser Sheet/film

Typical applications of light diffuser sheet/film include OLED displays, area diffusers for LED lighting, backlit displays, signage, light fixtures, photography, and many other applications. Click here to see more.

UVTECO advises to choose polycarbonate light diffusers when the diffusers are required to be impact resistant and flame retardant. Polycarbonate light diffuser is about 250 times harder than glass and about 25 times harder than acrylic. It also has a high resistance to temperature ranging from -50℃ to 120℃. UVTECO can provide custom size polycarbonate light diffusers according to your requirements.

Yes. If you have any requirements in outdoor use. UVTECO will perform UV coating on light diffusers’ surface. It makes them be able to withstand most harmful UV rays and makes them long life in outdoor use.

It depends on your requirements. Polycarbonate light diffuser sheet is stronger than Acrylic. It has higher impact resistance and can be flame retardant. However, Acrylic lighter diffuser sheet transmits more light (about >92%) than Polycarbonate and is more resistant to UV rays. The final decision is made on practical applications.

There are many benefits when using polycarbonate light diffuser sheets. For example, they have high security and stability. Polycarbonate lighter diffuser sheets offer great impact resistance and can be flame retardant. Also, UVTECO polycarbonate light diffuser sheets have a long lasting service life.

Yes. What UVTECO can provide is not only high quality polycarbonate, but also custom machining service.

The main differences are:

  • Impact resistance: Polycarbonate is about 25 times stronger than acrylic.
  • The hardness of the surface: Acrylic offers better surface hardness than polycarbonate.
  • Transmittance of light: Acrylic has a bit higher transmittance of light than polycarbonate.

These differences make them useful and irreplaceable in specific applications.
