Abstract

The present invention provides a multi-in-one LED display screen module welding. The carrier of the welding is a quadrangular hollow ceramic prefabricated component base in a shape of rectangle-terrace. The base of the prefabricated component is a printed circuit board with two to four layers. The upper surface of the printed circuit board is provided with two-dimension lattice points attached with or welded with LED chips. A protecting glue is filled in the hollow portion of the reflection bowl. The LED display screen module with small volume, compact structure, good heat radiation effect and long service life, high definition and performance-price ratio is formed by the welding. The definition of the LED display screen module is improved by four times to the real pixel display with the same points by the virtual pixel display control technology on the basis of the real pixel luminescent device. The virtual pixel display screen achieves the same display effect corresponding to a quater area of the real pixel display screen.

Description

technical field [0001] The invention relates to a display screen module using a semiconductor light-emitting diode (LED) as a luminous body, in particular to a surface mount of an LED display screen module and a corresponding display screen module, belonging to the technical field of semiconductor lighting. Background technique [0002] In recent years, semiconductor lighting technology has made great progress, and its core technology is the development of display module solutions. Several common display screen schemes can be divided into the following types. Dot matrix module scheme: the earliest design scheme, developed from the indoor pseudo-color dot matrix screen. Advantages: the cost of raw materials is the most advantageous, and the production and processing process is simple, the quality Stablize. Disadvantages: poor color consistency, serious mosaic phenomenon, and poor display effect. Single lamp solution: In order to solve the color problem of the dot matrix scr...
