Anti-blue-light eye-protection rear projection imaging film and projection screen

Abstract

The invention discloses an anti-blue-light eye-protection rear projection imaging film. The rear projection imaging film sequentially comprises a substrate layer, a bonding layer, a blue light absorbing layer and a projection display layer, the substrate layer is used for protecting and supporting the rear projection imaging film, the blue light absorbing layer is used for absorbing harmful blue light, the projection display layer is used for displaying projection images to improve the brightness, the contrast ratio and the color saturation of the projection image. The invention further discloses a projection screen. The projection screen comprises the anti-blue-light eye-protection rear projection imaging film, the anti-blue-light eye-protection rear projection imaging film comprises the blue-light absorbing layer, and 99% of harmful blue light can be effectively absorbed and filtered, so the purposes of preventing blue light and protecting eyes are achieved, the projection display layer comprises gas-phase-method silicon dioxide with the particle size of 15-20 [mu]m, and can present projection images with high brightness, high contrast and high color saturation.

Problems solved by technology

[0003] Nowadays, projection technology has been widely used in life and work, but there are still many problems in projection technology that cannot be effectively solved. For example, when working in a bright environment, its surface is very easy to be affected by strong light.

Another example is that the projection technology in the existing technology cannot effectively remove the harmful blue light and solar effect in the projected image, which will easily lead to visual fatigue of the user, seriously affect the perception, and even hurt the user's eyes.
