LED (light emitting diode) display screen

Abstract

The invention discloses an LED (light emitting diode) display screen, which comprises a first LED box body, a second LED box body, an LED display module and fastening elements, wherein more than two first grooves are formed in the end surface of the first LED box body; two first positioning bulges are arranged in each first groove; more than two second grooves are formed in the end surface of the second LED box body; two second positioning bulges are arranged in each second groove; the two first positioning bulges are respectively inserted into the corresponding second groove and are positioned between the two second corresponding positioning bulges; the two second positioning bulges are respectively inserted into the corresponding first groove; positioning holes are respectively formed in each first positioning bulge and each second positioning bulge; the distance from the center of each positioning hole to the corresponding pixel point on the LED display module is a half of a point distance of the LED display screen; the fastening elements are respectively and sequentially inserted into the positioning holes of the first positioning bulges and the second positioning bulges. The LED display screen has the beneficial effects that the splicing flatness is high; the showing effect is good; the processing is simple; the splicing is convenient.

Description

Technical field [0001] The present invention relates to the technical field of display screens, in particular to an LED display screen. Background technique [0002] LED display screens are usually made into a box structure, and then multiple LED display boxes are assembled into LED display screens of different sizes. The LED display cabinet includes a display module and an outer cabinet. The dot pitch of the display modules must be the same to ensure a good projection effect; therefore, when the cabinets are spliced, it is necessary to ensure the pixel points on the edges of two adjacent cabinets. The spacing between the points is the same as the standard design point spacing, and the flatness of the splicing of the box should also be ensured. [0003] In the prior art, multiple boxes with the same external dimensions are generally seamlessly connected by a locking mechanism to ensure the same distance between the pixels on the edges of the two boxes, such as the patent applicati...

Problems solved by technology

However, with this connection method, when tightening the slider connector, pay attention to observe the flatness of the display screen and adjust it in time. This requires experienced operators to set up, and there are certain restrictions on operators. In actual settings, it is not possible. Realize the real seamless splicing of the cabinets, and it is difficult to ensure that the sizes are exactly the same during the processing of the cabinets, so in actual use, it is difficult to keep the dot spacing of the LED display consistent, which affects the projection effect
