Problems solved by technology

The mask structure requires a certain compressive and impact strength, and there is a contradiction between the above-mentioned required mechanical strength and atomization. Generally, the height of the mask structure is 8mm, but to achieve the required atomization effect, its height needs to be at least 12mm Above, the atomization effect is closely related to the height of the mask structure. The higher the mask structure, the greater the diffusion of the point light source, and the worse the mechanical properties will be.

Embodiment Construction

[0037] figure 1 Show the basic structure of the light-transmitting mask that the LED pixel point of the present invention evenly diffuses, as figure 1 The light transmissive visor shown includes:

[0038] The mask body 1 located at the uppermost end is used to transmit the light emitted by the LED and act as the ground of the stage;

[0039] The grid body 2 located under the mask body 1 is used to guide the light emitted by the LED into the mask body 1, and helps to weaken the black band between each pixel on the mask; and

[0040] The circuit board 3 on which a plurality of LED light-emitting elements are mounted under the grid body 3, wherein each LED is higher than the substrate of the circuit board, so that each LED can enter the corresponding space 23 of the grid body 3 middle.

[0041] figure 2 and image 3 The structure of the mask body 1 of the present invention is shown. Such as figure 2 As shown, the mask body 1 is gray, and a plurality of mask units 13 sepa...

Abstract

The invention discloses a transparent veil with evenly dispersed LED pixel points. The transparent veil comprises a veil body, a grid body positioned under the veil body and a circuit board which is positioned under the grid body and is provided with a plurality of LED luminous elements. A plurality of veil units formed by a plurality of transverse walls and a plurality of vertical walls are distributed on the grey veil body evenly; a plurality of blank units formed by a plurality of transverse clapboards and a plurality of vertical clapboards are distributed on the light white transparent grid body evenly. Each veil unit of the veil body is a pixel square grid of the veil body; and each blank unit of the grid body is in accordance with the corresponding veil unit. The transparent veil can lead the whole display screen showing a luminous surface but not single pixel points, and can play clear video images.

Description

technical field [0001] The invention relates to an LED screen, in particular to a light-transmitting mask with an atomization effect in which LED pixels are uniformly diffused. Background technique [0002] With the rapid progress of LED technology, the use of LED display screens as the background of performances has become very mature, but the application of ground LED screens is rarely seen. The characteristic of ground LED screens in performance applications is that actors stand directly on the screen, That is to say, the actor is close to the background of the screen. When shooting at a 45-degree angle, the background is only about 3 meters away from the actor, while the vertical LED screen used as a canopy is generally more than 6 meters away from the actor. Since the ground LED screen is very close to the actors, when shooting close-up shots, the glare of the LED pixels that have not been fogged will seriously interfere with the shooting effect. Before, all the LED sc...
