Description

Technical Field

[0001] The invention relates to the field of display screens, and in particular to a face mask and a display screen. Background Art

[0002] LED display screens are widely used in occasions such as stages or exhibitions due to their high brightness, high resolution and large visual field. In occasions such as stages and exhibitions, the ambient light (such as lights and sunlight) is relatively bright. If you want the LED display screen to have a good effect, you need to form a high contrast between the LED display screen and the ambient light. In order to reduce the interference of ambient light on the display effect of the LED display screen, a mask is generally installed on the LED display screen. The mask is provided with convex ridges extending horizontally or vertically as a light-blocking part. On the one hand, it can absorb part of the light; on the other hand, it can reflect and disrupt part of the light to reduce the ambient light entering the human eye and improve the contrast between the LED display screen and the ambient light. The inventor found that the current light-blocking part of the mask is a single layer, which can only absorb or reflect the light from the front, and cannot absorb or reflect the light from the two sides.

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific implementation disclosed below.

[0033] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0035] See also Figure 1 A display screen includes a display unit 200 and a mask 100. The display unit 200 uses LED display technology to display pictures or numbers. The mask 100 is fixed to the display unit 200. The specific fixing method can be pasting, clamping or screw connection.

[0036] See also Figure 3 and Figure 5The mask 100 includes a main body 1, a first light-blocking layer 2 and a second light-blocking layer 3. The main body 1 has a light-transmitting hole 101. The light-transmitting hole 101 matches the lamp beads of the display unit 200 so that the light of the lamp beads can pass through the mask 100. In some embodiments, the light-transmitting hole 101 is a rectangular through hole. The first light-blocking layer 2 is arranged around the light-transmitting hole 101; the first light-blocking layer 2 has a first groove 201, which can increase the surface area of ​​the first light-blocking layer 2 and increase the ability of the first light-blocking layer 2 to absorb light on the one hand; on the other hand, the setting of the first groove 201 can change the reflection surface of the light, thereby disrupting the reflected light. The second light-blocking layer 3 is arranged around the first light-blocking layer 2, and the first light-blocking layer 2 and the second light-blocking layer 3 are stepped, and the first light-blocking layer 2 is higher than the second light-blocking layer 3. Compared with the existing single-layer light-blocking part, which can only process the light from the front, the first light-blocking layer 2 and the second light-blocking layer 3 are stepped, which can not only process the light from the front, but also process the light from both sides, so that the display screen and the ambient light have a better contrast. The second light-blocking layer 3 has a second groove 301, and the benefits of the second groove 301 refer to the first groove 201.

[0037] See also Figure 3 and Figure 5 The first groove 201 divides the first light-blocking layer 2 into a plurality of first light-blocking portions 202, and the first light-blocking portions 202 are in the shape of a quadrangular pyramid. The first groove 201 is in a V-shape or a trapezoid with a narrow bottom and a wide top, so that more ambient light can be irradiated onto the surface of the first light-blocking portion 202, so that the first light-blocking portion 202 absorbs or reflects ambient light. The first groove 201 blocks the light-transmitting hole 101 (such as Figure 3 ) or conduction (such as Figure 5 ). If the first groove 201 blocks the light-transmitting hole 101 (see Figure 3 ), the first groove 201 has a first side surface a2011 on the side close to the light-transmitting hole 101, and the first side surface a2011 can be a vertical surface or an inclined surface.

[0038] See also Figure 3 and Figure 5 The second groove 301 divides the second light-blocking layer 3 into a plurality of second light-blocking portions 302. The top of the second light-blocking portion 302 is flush with the bottom of the first light-blocking portion 202. The second groove 301 is V-shaped (eg Figure 3 ) or trapezoidal (such as Figure 5), the second light blocking portion 302 is in the shape of a triangular prism. The second groove 301 has a first side b3011, a second side b3012 and a third side b3013, the first side b3011 is close to the first light blocking layer 2, and the first side b3011 can be a vertical surface or an inclined surface. If the first side b3011 is an inclined surface, the inclination angle can be the same as the second side b3012 or the third side b3013. The first side b is adjacent to the second side b3012 and the third side b3013, and the second side b3012 and the third side b3013 are opposite. The second side b3012 and the third side b3013 are inclined surfaces, and the angles between the second side b3012 and the third side b3013 and the horizontal plane can be the same or different. The first light blocking portion 202 corresponds to the second groove 301 (such as Figure 5 ) or the first groove 201 corresponds to the second groove 301 (such as Figure 3 ).

[0039] See also Figure 3 and Figure 5 The mask 100 further includes a third light-blocking layer 4, which is arranged around the second light-blocking layer 3. The third light-blocking layer 4 has a third groove 401. The third groove 401 corresponds to the second groove 301. The third groove 401 is V-shaped or a trapezoidal shape with a narrow bottom and a wide top; the third groove 401 divides the third light-blocking layer 4 into a plurality of third light-blocking portions 402 in the shape of triangular prisms. The third light-blocking layer 4 and the second light-blocking layer 3 may have the same structure.

[0040] See also Figure 3 In some embodiments, the third light-blocking layer 4 and the second light-blocking layer 3 are stepped, and the second light-blocking layer 3 is higher than the third light-blocking layer 4. The top of the third light-blocking portion 402 is flush with the bottom of the second light-blocking portion 302. Figure 5 In some other embodiments, the third light-blocking layer 4 is flush with the second light-blocking layer 3, and the third light-blocking layer 4 is separated from the second light-blocking layer 3 by the partition 5. The partition 5 is in the shape of a triangular prism.

[0041] Here, the mask 100 is only shown to have three light-blocking layers, and the mask 100 can also be designed to have more than three light-blocking layers according to actual needs. A gap 6 is left between two adjacent bottom light-blocking layers (the third light-blocking layer 4 in the figure) so that ambient light can be irradiated onto the light-blocking layer, which is convenient for the light-blocking layer to absorb and radiate.

[0042] The mask 100 includes a first surface and a second surface opposite to the first surface, the first surface having the first light-blocking layer 2 and the second light-blocking layer 3, and the first surface is at least partially black so that the mask 100 can better absorb ambient light. In some embodiments, not only the first surface of the mask 100 is black, but the entire mask 100 is black. The first surface is black because the first surface is provided with a black light-absorbing layer, and the black light-absorbing layer can be black paint, or other black materials. It is also possible that the original color of the mask 100 is made of a black material with good light absorption.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
