The application of Fresnel lenses in projection systems. Fresnel lenses have proven to be the preferred lens in projection systems, and their role is to collimate and focus light. The Fresnel lens mobilizes the beam source recovered by the light source into parallel light, which significantly improves the brightness of the panel and eliminates the solar spot effect, thereby improving the brightness uniformity of the whole. A Fresnel lens is generally used in conjunction with the remaining display components, such as cylindrical mirrors.
The advantage of using a Fresnel lens in a projection system is that it focuses on or aligns the light to increase the brightness of the enhancement. If the collimator is eliminated, the light will lose a lot when passing through the panel, and the apparent heat will appear in the appearance. The plaque effect increases the brightness of the screen. Similarly, on the other side of the LCD screen, we must also collect light from the panel into the projection lens.
