The micro-prism structure in face, the micro-prism structure include multiple prism bars with inclined-plane side by side at zigzag, the prism bar by
The center of light-transmitting plate is respectively parallel to the extending direction toward extension at each frame of screen, and along the prism bar that each frame extends
The prism bar of frame, two neighboring extending direction is mutually linked, in each direction from light-transmitting plate center toward the prism of screen frame
The inclined-plane angle with horizontal plane of item, which gradually changes, stretches the display picture of viewing area equably to frame.
The micro-prism structure and light-transmitting plate are integrally formed.
The micro-prism structure is attached on the light-emitting surface of light-transmitting plate.
The light-transmitting plate is formed by transparent material.
The light-transmitting plate is formed by acrylic or glass.
The overall thickness of the light-transmitting plate and micro-prism structure is 2.4 mm-9.5 mm.
The overall thickness of the micro-prism structure is 0.09 mm-0.95 mm.
The inclined-plane angle with horizontal plane range of the prism bar is 10 ° -75 °.
The prism bar length is gradually increased along extending direction.
The invention adopts the above technical scheme, the prism with inclined-plane is arranged in euphotic cover plate light-emitting surface whole face, by adjustment
Each prism hypotenuse/facet surfaces angle controls anaclasis position, makes entire picture Uniform Tension, solves screen edge picture stretching problem.Separately
Outside, masking picture is reflected in light-transmitting plate light-emitting surface due to ambient light, light transmission plate surface setting prism can be reflected ambient light
To elsewhere, solve the problems, such as that display picture is reflective.

Specific embodiment
As shown in one of attached drawing 1-3, the present invention includes the display screen 1 mutually spliced, and the front of the display screen 1, which is equipped with, to be covered
Cover the light-transmitting plate 2 on the viewing area of display screen 1 11 and frame 12, the front surface of light-transmitting plate 2 is light-emitting surface, on the light-emitting surface
Equipped with the micro-prism structure 3 for covering entire light-emitting surface, the micro-prism structure 3 includes multiple prism bars with inclined-plane side by side at saw
Dentation, the prism bar from the center of light-transmitting plate 2 toward each frame 12 of screen at extend, and along each frame 12 extend prism bar
It is respectively parallel to the frame 12 of the extending direction, the prism bar of two neighboring extending direction is mutually linked, in each direction from saturating
The inclined-plane angle with horizontal plane of tabula rasa center toward the prism bar of screen frame, which gradually changes, makes the display picture of viewing area equably
It is stretched to frame.
Further, the light-transmitting plate 2 is formed by transparent material.
Further, the light-transmitting plate 2 is formed by acrylic or glass.
Further, the overall thickness of the light-transmitting plate 2 and micro-prism structure 3 is 2.4 mm-9.5 mm.
Further, the overall thickness of the micro-prism structure 3 is 0.09 mm-0.95 mm.
Further, the inclined-plane angle with horizontal plane range of the prism bar is 10 ° -75 °.
Further, the prism bar length is gradually increased along extending direction.
As shown in Fig. 1, in the preferred embodiment of the present invention, the micro-prism structure 3 and 2 one of light-transmitting plate at
Type.
As shown in Fig. 2, in another embodiment of the invention, the micro-prism structure 3 is attached to the light out of light-transmitting plate 2
On face.
