Novel high-density small-spacing LED display screen

Abstract

The invention discloses a novel high-density small-spacing LED display screen. The novel high-density small-spacing LED display screen structurally comprises a high-density display screen, a drive board, bottom feet and an efficient heat dissipation lamp panel. The drive board is arranged between the high-density display screen and the efficient heat dissipation lamp panel, the bottom of the drive board is supported by the bottom feet in a perpendicular mode, and the high-density display screen, the drive board and the efficient heat dissipation lamp panel are parallel to one another. The high-density display screen is composed of a small-spacing module, an optical filter, a black transistor, a polarizer and a black packaging substrate, the small-spacing module is arranged on the optical filter, and the small-spacing module is closely connected with the optical filter, the black transistor, the polarizer and the black packaging substrate in sequence. The drive board is provided with an input-output interface and a drive chip, and the drive chip is arranged in the drive board. By arranging the efficient heat dissipation lamp panel, internal heat is dissipated from a side wing machine and a rear cover, and silence is guaranteed under full heat dissipation; meanwhile, the display screen is small in point spacing and high in resolution ratio.

Description

technical field [0001] The invention is a novel high-density small-pitch LED display screen, which belongs to the technical field of high-density small-pitch LED display screens. Background technique [0002] Small-pitch LED display refers to indoor LED displays with LED dot pitches below P2.5, mainly including P2.5, P2.083, P1.923, P1.8, P1.667, P1.5 and other LED displays screen products. With the improvement of LED display manufacturing technology, the resolution of traditional LED display has been greatly improved. [0003] The existing public technology application number is: 201620974859.7 A display screen, including a base, a lamp board and a mask, wherein the first end surface of the base is provided with an array of grooves; the lamp board is paved on the first end surface of the base, and the lamp The corresponding groove on the board is provided with a luminous lamp, and the luminous lamp is installed and clamped in the groove facing outward; the mask is install...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the existing technology, the purpose of the present invention is to provide a new type of high-density small-pitch LED display to solve the problem that the existing distance LED display has poor heat dissipation effect, and at the same time, it cannot guarantee the quietness while dissipating heat.
