Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, but rather should be construed as broadly as the present invention is capable of modification in various respects, all without departing from the spirit and scope of the present invention.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1, a display screen includes a display unit 200 and a mask 100, wherein the display unit 200 can display pictures or numbers by using LED display technology. The mask 100 is fixed to the display unit 200. The specific fixing mode can be sticking, clamping or screw connection and the like.
Referring to fig. 3 and 5, the mask 100 includes a body portion 1, a first light-blocking layer 2, and a second light-blocking layer 3, the body portion 1 has a light-transmitting hole 101, and the light-transmitting hole 101 is matched with a lamp bead of the display unit 200, so that light of the lamp bead can pass through the mask 100. In some embodiments, the light-transmissive holes 101 are rectangular through holes. The first light blocking layer 2 is arranged around the light transmission hole 101; the first light blocking layer 2 is provided with a first groove 201, so that on one hand, the surface area of the first light blocking layer 2 can be increased, and the capacity of the first light blocking layer 2 for absorbing light rays is increased; on the other hand, the arrangement of the first groove 201 can change the reflection surface of the light, thereby disturbing the reflected light. The second light-blocking layer 3 is disposed around the first light-blocking layer 2, the first light-blocking layer 2 and the second light-blocking layer 3 are in a step shape, 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, the light blocking part can only process the light irradiated from the front side, the first light blocking layer 2 and the second light blocking layer 3 are in a step shape, the light irradiated from the front side can be processed, the light irradiated from the two sides can be processed, and the display screen and the ambient light have better contrast. The second light-blocking layer 3 has a second groove 301, the benefits of the second groove 301 being with reference to the first groove 201.
Referring to fig. 3 and 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 a shape of a quadrangular frustum pyramid. The first groove 201 is in a V-shaped pattern or a trapezoid with a narrow lower portion and a wide upper portion, so that more ambient light can irradiate the surface of the first light blocking portion 202, and the first light blocking portion 202 can absorb or reflect the ambient light. The first groove 201 is blocked from (as shown in fig. 3) or conducted to (as shown in fig. 5) the light hole 101. If the first groove 201 is blocked from the light-transmitting hole 101 (see fig. 3), one side of the first groove 201 close to the light-transmitting hole 101 has a first side surface a2011, and the first side surface a2011 may be a vertical surface or an inclined surface.
Referring to fig. 3 and 5, the second grooves 301 separate 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 has a V shape (see fig. 3) or a trapezoidal shape (see fig. 5), and the second light-blocking portion 302 has a triangular prism shape. The second groove 301 has a first side surface b3011, a second side surface b3012 and a third side surface b3013, the first side surface b3011 is close to the first light blocking layer 2, and the first side surface b3011 may be a vertical surface or an inclined surface. If the first side b3011 is an inclined surface, the inclination angle may be the same as the second side b3012 or the third side b 3013. 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 surface b3012 and the third side surface b3013 are inclined surfaces, and the included angles between the second side surface b3012 and the third side surface b3013 and the horizontal plane may be the same or different. The first light blocking part 202 corresponds to the second groove 301 (see fig. 5) or the first groove 201 corresponds to the second groove 301 (see fig. 3).
Referring to fig. 3 and 5, the face mask 100 further includes a third light-blocking layer 4, the third light-blocking layer 4 being disposed 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 in a V shape or a trapezoid with a narrow lower part and a wide upper part; the third groove 401 divides the third light-blocking layer 4 into a plurality of third light-blocking portions 402 having a triangular prism shape. The third light-blocking layer 4 may have the same structure as the second light-blocking layer 3.
Referring to fig. 3, in some embodiments, the third light-blocking layer 4 is stepped with the second light-blocking layer 3, and the second light-blocking layer 3 is higher than the third light-blocking layer 4. The top of the third light blocking part 402 is flush with the bottom of the second light blocking part 302. Referring to fig. 5, in 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 means of the separator 5. The partition 5 has a triangular prism shape.
The mask 100 has three light-blocking layers, and the mask 100 can be designed to have more than three light-blocking layers according to actual needs. A gap 6 is left between two adjacent bottommost light-blocking layers (in the figure, the third light-blocking layer 4), so that ambient light can irradiate on the light-blocking layers, and the light-blocking layers can absorb and radiate the ambient light.
The face mask 100 comprises a first side having the first light-blocking layer 2 and the second light-blocking layer 3 and a second side opposite to the first side, the first side being at least partially black in color for better absorption of ambient light by the face mask 100. In some embodiments, more than the first side of the mask 100 is black, and the mask 100 is black throughout. The first surface is black, the first surface can be provided with a black light absorption layer, the black light absorption layer can be black paint, and other black materials can be certainly also adopted. The mask 100 may be made of a black material that absorbs light.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
