Problems solved by technology

If this connection method is used, on the one hand, the setting of the connecting plate will increase the cost; on the other hand, the connection accuracy of the box will be directly affected by the accuracy of the box, and the flatness is difficult to control
In addition, there are a variety of LED display cabinet locking mechanisms, which use cams, levers and other principles to design more complex structures, which can directly lock two adjacent display cabinets quickly. Although these locking mechanisms can avoid Use the connection board to quickly complete the splicing of the display screen, but the splicing accuracy is poor, the flatness of the display screen after splicing is not good, and it is prone to bending, warping, etc., and the connection strength of these locking mechanisms is not enough, it is difficult to ensure the stability of the splicing of the display screen sex

Embodiment

[0026] Please refer to figure 2 , Embodiment 1 of the present invention is: an LED display screen, comprising at least two LED display screen cabinets.

[0027] Please refer to figure 1 , the LED display box includes a front and a back, and the front is used to install the LED display module. The shape of the box body is rectangular, which includes four sides all around. On the back of the box body, two adjacent sides are provided with protrusions 1, and the remaining two sides are provided with connecting parts 2 (that is, among the opposite sides, one side is provided with protrusions 1). part 1, the other side is provided with a connecting part 2). The protruding part 1 and the connecting part 2 are integrally formed with the LED display screen case. The protruding part 1 of one LED display screen case can be matched and connected with the connecting part 2 of an adjacent LED display screen case, so that the two LED display screen cases are spliced ​​together. In this...

Abstract

The invention discloses an LED display screen box. The sides of the LED display screen box are provided with at least one protruded part and at least one connecting part respectively, the protruded part comprises a first protruded part and a second protruded part which are sequentially connected, the distance between the protruded surface of the first protruded part and the box is larger than the distance between the protruded surface of the second protruded part and the box, the connecting part comprises a first connecting surface and a second connecting surface which are connected sequentially, and the distance between the first connecting surface and the box is larger than the distance between the second connecting surface and the box. The protruded part and the connecting part are arranged into a step shape, so that the connecting position of the display screen box can be in staggered stereoscopic layout, the display screen splicing flatness is controlled, and splicing precision is guaranteed.

Description

technical field [0001] The invention relates to the technical field of display screens, in particular to an LED display screen and a box thereof. Background technique [0002] LED technology has been widely used in all aspects of life. There are many occasions that require a larger screen LED display, which requires splicing multiple LED display cabinets. The flatness of the LED display screen has always been a key factor in the display effect. The flatness seriously affects the luminous angle of the display screen and the uniformity of viewing consistency. Therefore, when the display cabinets are spliced, it is necessary to ensure the splicing flatness of the cabinets. [0003] In the prior art, a connecting board is generally arranged to splicing together a plurality of LED display cabinets. If this connection method is used, on the one hand, the setting of the connecting plate will increase the cost, and on the other hand, the connection accuracy of the box body will be ...
