I-DIF 20
I-DIF is a high-performance diffusive film designed to evenly distribute light and maximize brightness in LED lighting systems. With up to 99% light transmittance, it enhances illumination while supporting both edge-lit and direct-lit designs. Its thin, flexible structure allows for creative design and efficient production.
I-DIF is available in various versions.
For more information, please check the datasheet or contact us.
LED hiding ratio
The LED hiding ratio is the relation between the pitch of the LEDs (distance between the LEDs) and the distance from LED to diffuser film.
