Abstract

The invention discloses a high-density and small-spacing LED display screen. The high-density and small-spacing LED display screen comprises a high-density display screen, a display screen frame, a display screen back cover and an organic glass, wherein the high-density display screen is composed of a small-spacing module, an optical filter, a black transistor, a polarized film and a black packagesubstrate, the small-spacing module has high brightness, high density, large viewing angle and high stability, matte surface treatment is performed on the surface of the small-spacing module, a firstheat dissipation window is processed in a left cover plate, a second dissipation window is processed in a right cover plate, and a heat dissipation channel is formed between the first heat dissipation window and the second heat dissipation window to form convection and has a good heat dissipation effect. As an upper row of positioning columns are installed in an upper row of positioning holes, alower row of positioning columns are installed in a lower row of positioning holes, a left row of positioning columns are installed a left row of positioning holes, and a right row of positioning columns are installed in a right row of positioning holes, organic glass is installed and prevented from falling off; the display screen back cover is arranged to protect the display screen.

Description

technical field [0001] The invention relates to the technical field of display screens, in particular to a high-density small-pitch LED display screen. Background technique [0002] In the rapid development of today's modern information society, large-screen display has penetrated from commercial applications such as public information display to consumer multimedia applications. With the development of broadband networks, digital multimedia content will occupy the mainstream in the information world, and new large-screen display devices will replace traditional TV sets as the center for people to enjoy information and multimedia content. [0003] LED display is the English abbreviation of Light Emitting Diode. It is a display method by controlling semiconductor light-emitting diodes. Its general appearance is composed of many light-emitting diodes, usually red, and characters are displayed by turning on and off the lights. A display screen used to display various informat...
