Problems solved by technology

However, once the screen is exposed to light, all colors are immediately covered by the light and become diluted, especially the blue (only 11%) information loss is the most significant, thus forming a color gamut mismatch ( Mapping) image distortion
[0004] Therefore, regardless of whether it is a curtain or a metal curtain, the phenomenon of image color fading and color gamut shift caused by turning on the light is really a problem that needs to be overcome.

Embodiment Construction

[0019] As shown in Figure 2 and Figure 3-1, it is a preferred embodiment of the full-color gamut reflective screen of the present invention, which mainly includes a reflective layer 1, and a light-transmitting layer 2 that is in contact with the reflective layer 1 .

[0020] The reflective layer 1 is made of a metal material with a high light reflection coefficient, and has a concave-convex surface 11 on its surface. The wrinkled surface 11 can be formed by mechanical processing or chemical etching for To diffuse and reflect light within a designed angle, the reflective layer 1 in this embodiment is made of aluminum metal, and its diffuse reflection angle is about 80 degrees (within the half-gain viewing angle range).

[0021] The transparent layer 2 is made of a polymer (Polymer) material, and has a smooth contact surface 20 attached to the wrinkled surface 11 of the reflective layer 1, and a contact surface opposite to the contact surface. 20 and a rough light-receiving sur...

Abstract

The invention relates to whole color gamut reflecting screen. It includes one reflecting layer and one euphotic layer which has one smooth connecting surface, one opposite coarse light receiving surface, and one middle interlayer has many light tight corpuscles part of which forms semicircle convex corpuscle group; and part of which forms surface contacting group. Greater part of the oblique incidence light and the projecting light are respectively absorbed and reflected by the high low fluctuation arrange of the semicircle convex corpuscle group and gloomy background. Thus the entirety can appear whole color gamut color and high contrast image at the condition of light on.

Description

technical field [0001] The invention relates to a screen for a projector, in particular to a full-color gamut reflective screen with a dark gray surface structure that can display full-color gamut colors and high-contrast images when the light is turned on for projection. Background technique [0002] At present, the reflective screens used in general TV projectors can be roughly divided into two categories: cloth screens and metal screens. As for the screen, its gain is low, and it is only suitable for use in dark places. If it is placed under the light for projection, the color of the image presented will inevitably fade, and the surface of the screen will be covered with a layer of mist; , the gain of the metal screen is higher, and when it is projected under bright lights, it can still present a high-contrast image with more vivid colors than the screen. But the fly in the ointment is that the metal curtain will still be weakened by the bright light when the light is tu...
