HIGH-DEFINITION LED DISPLAY SCREEN AND SURFACE-MOUNTED LED COMPOSITE LAMP WITH SUPER-SMALL POINT DISTANCE THEREOF

The invention discloses a high-definition LED display screen and a surface-mounted LED composite lamp with an ultra-small point distance thereof. The high-definition LED display screen comprises a plurality of surface-mounted LED composite lamps with an ultra-small point distance. The surface-mounted LED composite lamp with an ultra-small point distance comprises a lamp body, a plurality of pins arranged on the surface of one side of the lamp body, and a plurality of groups of LED pixel lamps arranged in an array on the surface of the other side of the lamp body, of which the periphery are wrapped with transparent packages, each group of LED pixel lamps being electrically connected with the pins. This modularized design, wherein the plurality of groups of LED pixel lamps are arranged in an array on the surface of one side of the lamp body and correspondingly the plurality of pins are arranged on the surface of the other side of the lamp body, will help a high-definition LED display screen having surface-mounted LED composite lamps with an ultra-small point distance that employ the technical solutions provided in this invention to improve display quality and greatly reduce manufacturing difficulty and costs.
