Description

Technical Field

[0001] The utility model relates to the technical field of display screen masks, in particular to an LED display screen mask which is easy to install and has a high contrast. Background Art

[0002] The face mask of LED display refers to the outer protective cover of LED display, which is usually made of special materials, such as PC+10% GF, and added with pure black masterbatch, anti-UV agent and flame retardant, etc., to provide protection and enhance the display effect. The structural principle of the face mask is that the LED lamp beads on the display panel emit light, and then spread out through the material of the face mask to form clear images and text. The role of the face mask is multifaceted. It can not only protect the LED lamp beads inside the LED display from the influence and damage of the external environment, but also improve the display effect and increase the brightness and clarity of the display.

[0003] For example, a high-contrast LED display screen mask disclosed in the authorization announcement number CN219936625U includes a mask body, a fixing buckle is integrally arranged on the back of the mask body, the mask body includes a panel fixedly mounted on the front of the LED display screen, and a light-through hole opened on the panel, the front of the panel is integrally connected with a reflective strip located above the light-through hole, the front of the panel is integrally provided with a light-blocking eave located below the light-through hole, the front of the panel is provided with a light-absorbing groove located outside the reflective strip, and the inner wall of the light-through hole is integrally provided with a focusing wall, which gathers the light emitted by the light-emitting LED in the LED display screen and simultaneously The light-blocking eaves and reflective strips reflect the scattered light of the light-emitting LEDs, and then reflect and absorb the light emitted by other light-emitting LEDs through the light-blocking eaves, reflective strips and light-absorbing grooves, so that the light of the light-emitting LEDs is amplified. However, this technical solution mainly utilizes the fixing buckle on the back of the mask body and the front wall of the LED display screen for installation. At this time, only one connection point is formed between the fixing buckle and the front wall of the LED display screen. This connection method may become loose when facing external impact or vibration, especially under natural disasters such as strong winds outdoors or the action of external forces. The single connection point is difficult to withstand external forces, resulting in deformation, falling off and other problems of the mask. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-6 The utility model provides an embodiment: an LED display screen mask with high contrast that is easy to install, comprising an LED display screen mask body 1 and a plurality of equally spaced lamp grid holes 2 arranged on the surface of the LED display screen mask body 1, the four corners of the inner wall of the lamp grid hole 2 are all arc-shaped transitions, and a junction is formed between the four adjacent lamp grid holes 2, and a four-point connector 6 is installed at the junction on the back of the LED display screen mask body 1, and the back of the LED display screen mask body 1 is connected to the front wall of the LED display screen through the four-point connector 6 to form four connection points;

[0022] The LED display screen mask body 1 is made of PPO material. PPO material has high weather resistance and chemical resistance, and can resist the erosion of ultraviolet rays, high temperature, humidity and other factors in the daily environment, thereby extending the service life of the LED display screen mask. The surface of the LED display screen mask body 1 and the four-point connector 6 are sprayed with a matte black paint layer. The matte black paint layer has a certain light absorption, which can effectively reduce the reflection and glare on the surface, and improve the visibility of the LED display screen under different lighting conditions;

[0023] The four-point connection member 6 includes a cross connection plate 601 fixed at the junction, and a Z-shaped bending arm 603 integrally formed at the four ends of the cross connection plate 601. The surface of the Z-shaped bending arm 603 is provided with a completely penetrating circular hole. The side wall of the Z-shaped bending arm 603 away from the through hole 602 coincides with the side wall of the rear focusing wall 5. When the LED display screen mask body 1 and the LED display screen are connected, the Z-shaped bending arm 603 is attached to the front wall of the LED display screen. At this time, the Z-shaped bending arm 603 and the front wall of the LED display screen are still bonded to each other, and the convex column on the front wall of the display screen will penetrate to the outside of the circular hole of the Z-shaped bending arm 603. This structural design can effectively reduce the slight deviation or unevenness of the mask during the installation of the mask and the display screen, thereby improving the overall flatness and display effect of the display screen after the mask is installed, making the image and text clearer and more accurate;

[0024] A front light-collecting wall 3 is fixed to the edge of one end of the lamp grid hole 2 away from the four-point connector 6, and right-angle reflective eaves 4 are fixed to the corners of the surface of the front light-collecting wall 3. The cross-sectional shapes of the lamp grid hole 2 and the front light-collecting wall 3 are both rectangular. A rear light-collecting wall 5 is installed to the edge of one end of the lamp grid hole 2 close to the four-point connector 6. When the LED display screen is working, the structural design of the front light-collecting wall 3 and the rear light-collecting wall 5 can better control the emission direction and scattering range of light, and can refocus the reflected and refracted light, so that the light is more concentrated in the lamp grid hole 2, reducing the loss of light. In this process, the contrast of the LED display screen is improved by reducing the loss of light.

[0025] The opening of the rear light-focusing wall 5 decreases gradually from one end close to the lamp grid hole 2 to the other end. Through the gradually decreasing opening design, the rear light-focusing wall 5 can more effectively control and guide the focusing of light and reduce the reflection and refraction of light.

[0026] When the embodiment of the present application is in use, the staff first installs the four-point connector 6 on the back of the LED display screen mask body 1 in the form of bonding. The four-point connector 6 is located at the intersection formed by four adjacent lamp grid holes 2. Then the back of the LED display screen mask body 1 is opposite to the front of the LED display screen, and the back of the LED display screen mask body 1 is connected to the front of the LED display screen through the four-point connector 6. In this process, the staff can pre-form multiple bosses on the front of the LED display screen, so that the four-point connector 6 is connected to the bosses, and the back of the four-point connector 6 is bonded to the front of the LED display screen. At this time, the four-point connector 6 and the bosses will not block the lamp beads of the LED display screen. Compared with the previous design with only one connection point, four connection points are formed at the same position, which can distribute the installation force more evenly and effectively enhance the connection stability between the mask and the LED display screen. When facing external impact or vibration, this multi-point connection design can disperse the pressure and reduce the loosening or falling off that may occur at a single connection point, thereby more reliably maintaining the installation state of the mask.
