Description of the Invention: [Technical Field] The present invention relates to a display screen, and more particularly to a display screen having a high contrast. [Prior Art] In recent years, with the rapid development of projector technology, its brightness has increased from less than 500 lumens (unit of luminous flux) to more than 5000 lumens in the past, and the resolution has grown from 640x480 to over 1280x1024, but the display screen Technology has not been developed. In fact, high-quality images are an indispensable part of good screens, in addition to relying on good projectors. In order to improve the quality of the display, a screen with anti-reflective function is required, so that the viewer can watch in high definition without being disturbed by ambient light. A prior art display screen, as shown in the first figure, has a black grid structure comprising a first surface 10 and a groove surface 12, the groove surface 12 comprising a plurality of black layers 14 disposed thereon. The groove 122 and the light penetrating region 124. A light source of the projector (not shown) is perpendicularly incident from the first surface 10 of the display screen 1. The light is efficiently collected by the first surface 10 and projected from the light penetrating region 124. The black layer 14 disposed in the recess 122 is formed. It is used to absorb the scattered light that is not perpendicularly incident from the first surface 10 and the ambient light of the groove surface 12 (viewing surface), thereby improving the contrast of the screen. However, this one-dimensional groove 122 can only cover about 50% of the surface area, i.e., only 50% of the surface area covers the filled black layer, so that a better contrast cannot be achieved. In view of this, it is necessary to provide a display screen that can increase contrast. SUMMARY OF THE INVENTION It is an object of the present invention to provide a display screen that can increase contrast. 1311683 a plurality of micro-surfaces of the first substrate; the first substrate comprises two surfaces, the first ii ^ is further provided with a number of V-shaped grooves opposite to the first surface, and the surface is a light incident surface; a black layer covering the filling board as a substrate, which is attached to the second surface, and the second base is filled with the V-shaped groove of the display screen of the present invention.

The second substrate 230 includes a light anti-reflection layer or an anti-glare layer 232. The v-shaped groove 218 is filled with the black layer 220, and the second substrate 23 is bonded to the second surface 214. , the first plate 210 and the second substrate 230 are all made of glass, and the first surface 212 is formed by processing a lens of the first substrate 21, that is, the surface of the first substrate is mechanically ground to form a plurality of a semi-cylindrical microlens 212 〇 (such as the fourth figure hook). The second surface 214 is formed by processing the other surface of the first substrate 210 v_Cut, that is, the first surface of the first substrate 210 is formed by the dry side method. The V-shaped groove talks as shown in the fourth figure b) 'The V-shaped groove 218 is only disposed in the longitudinal direction (as shown in the perspective view of the fourth figure b, the fifth view, the black layer 220 covers the filling in the V-shaped groove 218 (as shown in the fourth figure). c) even if the first substrate 210 is placed in a high-temperature greenhouse (not shown) to soften and melt the state to cover the black layer 220, and then naturally cool to a temperature drop, for better subsequent placement in the room The second substrate 230 is also fixed to the second surface 214 when it is softened and melted in the high temperature chamber (as shown in FIG. 4D), and the viewing surface of the second substrate 230 includes an optical anti-reflection. a layer or anti-glare layer 232, so that the viewer can clearly view the projected image without being exposed to ambient light The principle is that when the light of the projector is perpendicularly incident from the first surface 212 of the display screen 2, the light is efficiently collected by the microlens 2120 of the first surface 212 and projected from the light penetrating region 216. The black layer 22 填充 filled in the v-shaped groove 218 is used for receiving the discrete light (not shown) that is not perpendicularly incident on the first surface 212 and the ring light of the viewing surface, and the optical resistance of the light passing through the second substrate 230 The reflective layer or the anti-glare layer 232 is emitted. Since the invention uses the V-shaped groove of the display screen to cover the black layer, that is, the black layer increases the surface area by replacing the conventional square one-dimensional structure with a triangular two-dimensional structure, the one-dimensional The structure has more than 70% of the surface covering filled with the absorbing layer, which will more effectively absorb the discrete light and the viewing surface that are not perpendicularly incident on the first surface to maintain the high contrast of the picture. The figure is a second embodiment of the display screen of the present invention, and the embodiment is different from the first embodiment in that the second surface 314 is provided with a V-shaped groove 316, and is also provided with a longitudinal v #, == "in the slot It can be stepped up and stepped up and the screen is thinner than the first-solid model, in which the black layer can be concave on the second surface, or can be highlighted by the color Jf. ΐSecond substrate is fixed and fixed; the first substrate can also be plastic and rubber base; the county color material can be domain (10) fat, and can also be light-colored and product-increasing, and the invention of special wealth, Xi Ren +, the only preferred embodiment of the invention, the equivalent of the invention in the spirit of the invention, or the equivalent of tb in the following patent application scope. 1311683 [Simple Description of the Drawings] The first figure is a schematic diagram of a prior art display screen.
