Problems solved by technology

[0002] At present, most of the pitch pixels that can be realized by the LED display unit boards on the market are 4mm, and the high-end pitch pixels can reach 2.5mm. The small pitch pixels can improve the display accuracy of the display screen and make the display content per unit area more delicate

Abstract

The invention relates to a silica-based unit board of an LED display screen. The silica-based unit board comprises an LED light emitting unit, a silica-based board unit, a circuit board unit and an electronic element unit. The LED light emitting unit is connected on the upper surface of the silica-based board unit, the lower surface of the silica-based board unit is connected with the upper surface of the circuit board unit, and the lower surface of the circuit board unit is connected with the electronic element unit. The LED light emitting unit is formed by LED pixel points which are distanced by 0.1-0.5mm, and each LED pixel point is composed of 1-3 LED light emitting individuals which are LED flip chips. The silica-based unit board of the LED display has the advantages of no packaging requirement, convenience in manufacturing, good radiating effect, small pixel distance and the like.

Description

technical field [0001] The invention relates to an LED display unit board, in particular to a low-pitch pixel silicon-based LED display unit board. Background technique [0002] At present, most of the pitch pixels that can be realized by the LED display unit boards on the market are 4mm, and the high-end pitch pixels can reach 2.5mm. The small pitch pixels can improve the display accuracy of the display screen and make the display content per unit area more delicate. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies in the prior art, and provide a silicon-based LED display unit board that does not require packaging, is easy to manufacture, has small pixel pitches, and has a good heat dissipation effect. [0004] According to the technical solution provided by the present invention, the silicon-based LED display unit board includes an LED light-emitting unit, a silicon substrate unit, a circuit board unit and an electro...
