Drawings
Fig. 1 is the structure schematic diagram of the display screen brightness enhancement film of the present invention.
Detailed Description
The invention will be further elucidated and described with reference to the following embodiments and drawings in which:
referring to fig. 1, a brightness enhancement film for a display screen includes a substrate 10 and a first prism structure layer 11 disposed above the substrate 10.
The first prism structure layer 11 is arranged above the substrate 10, and light emitted by the light source is gathered towards a user of the display device through the first prism structure layer 11, so that the purpose of improving the brightness of the display screen is achieved.
First prism structural layer 11 includes a plurality of first prism, and substrate 10 has been close to first prism structural layer 11 one side and has been seted up light-focusing groove 101, and light-focusing groove 101 corresponds and sets up in first prism below, and light-focusing groove 101 is seted up along first prism straight line extending direction, and the cross-sectional shape of light-focusing groove 101 perpendicular to first prism extending direction is the hemisphere type, and light-focusing groove 101 is protruding towards first prism one side.
When light enters the substrate 10 from the outside, the light is preliminarily converged through the light-condensing groove 101, the light is converged in the substrate 10 towards the convex structure on one side of the first prism by the light-condensing groove 101, so that the light is converged below the first prism, and the light is further converged by the first prism, so that the first prism is ejected out, and the brightness enhancement effect of the brightness enhancement film is improved.
The first prisms of the first prism structure layer 11 are arranged in sequence, and the first prisms are in contact with each other. And the first prisms include high prisms 111 and low prisms 112, and the high prisms 111 and the low prisms 112 are arranged in a ratio of 1: 5.
Carry out the setting of height combination with first prism, can effectively reduce the chance that lower prism 112 part has other objects to take place the contact, can continue to contact with other objects through high prism 111, thereby ensure the integrality on low prism 112 surface, reduce the emergence of wearing and tearing, and when having great pressure extrusion membrane surface of adding lustre to, utilize high prism 111 to cushion pressure earlier, thereby when making pressure and low prism 112 contact, its effort is less than the direct condition that takes place the contact, thereby play the purpose of protecting low prism 112 surface.
And the proportion of the high prisms 111 to the low prisms 112 is set according to the ratio of 1:5, so that the low prisms 112 between the two high prisms 111 can be effectively protected, and the problem that the low prisms 112 are directly contacted with other objects and cannot achieve the purpose of protection due to overlarge space between the two high prisms 111 is avoided.
A second prism structure layer 12 is arranged below the substrate 10, and the second prism structure layer 12 and the first prism structure layer 11 are arranged perpendicular to each other. Through setting up second prism structural layer 12, form two crisscross prism distributions with first prism structural layer 11, can adjust the angle of divergence and the light luminance that assembles of launching light from the light source for the membrane that adds lustre to can want better improvement luminance effect to light.
In the above scheme, the upper protection layer 13 is disposed above the first prism structure layer 11, and the lower protection layer 14 is disposed below the second prism structure layer 12. The first prism structure layer 11 and the second prism structure layer 12 are better protected by the upper protective layer 13 and the lower protective layer 14, and the first prism structure layer 11 and the second prism structure layer 12 are prevented from being scratched, so that part of light is normally converged. And the upper protective layer 13 and the lower protective layer 14 are made of transparent light-transmitting materials, so that the light rays converged by the first prism structure layer 11 and the second prism structure layer 12 are prevented from being blocked.
The utility model provides a display screen membrane of adding lustre to is equipped with first prism structural layer above the substrate, gathers to display device user direction through the light that first prism structural layer sent the light source to play the purpose that improves display screen luminance, the substrate is close to first prism structural layer one side and is equipped with the light-gathering groove, just the cross sectional shape of the first prism extending direction of light-gathering groove perpendicular to is the hemisphere type, and the light-gathering groove is protruding towards first prism one side, when light enters into the substrate from the outside, tentatively assembles light through the light-gathering groove earlier, utilizes the light-gathering groove to assemble light in the substrate towards the bellied structure in first prism one side, makes light assemble to the below of first prism, and rethread first prism carries out and further assembles light, thereby first prism jets out, thereby increases the improvement luminance effect of membrane of adding lustre to.
