Description

Technical Field

[0001] The utility model relates to the field of display screens, in particular to an LED display screen with a three-dimensional structure. Background Art

[0002] LED display is a display technology that uses light-emitting diodes (LEDs) as pixels to create images. It displays text, images, videos and other content by controlling the on and off of semiconductor light-emitting diodes. LED display has the characteristics of bright colors, seamless splicing, and long service life. Compared with traditional display technology, LED display has obvious advantages in response speed, brightness, color performance, etc. The structure of LED display includes modules, power switches, receiving cards, video processors and other components. It can be connected to computers, speakers, cameras and other equipment to display a variety of information, such as text, graphics, images, animations, quotes, videos, video signals, etc. The pixel pitch, brightness, contrast, refresh rate and viewing angle of the LED display screen determine the resolution, optimal viewing distance, vividness and clarity of the display effect, as well as the smoothness of dynamic images and the experience of the audience when watching at different positions. A Chinese patent discloses a three-dimensional indoor transparent LED display screen (authorization announcement number CN 203689844 U). The LED display module described in the patent technology is composed of a plurality of vertically structured LED modules, each of which has the same size and is in the shape of a long strip.
