Abstract

The invention discloses a light-emitting diode display screen and an application thereof. The LED (light-emitting diode) display screen comprises an LED display screen substrate, a control circuit, a first connector, a second connector and an LED crystal plate. The control circuit is arranged on the LED display screen substrate, an output end of the control circuit comprises a first electrode and a second electrode, the first connector is arranged on the first electrode, the second connector is arranged on the second electrode, the LED crystal plate is arranged between the first connector and the second connector, a third electrode is arranged between the LED crystal plate and the first connector, a fourth electrode is arranged between the LED crystal plate and the second connector, and an input end of the LED crystal plate comprises the third electrode and the fourth electrode. The LED display screen cools the LED crystal plate through the first electrode, the first connector, the third electrode, the second electrode, the second connector and the fourth electrode. The light-emitting diode display screen solves the technical problem of low cooling efficiency of an LED display screen in the prior art.

Description

technical field [0001] The invention relates to the field of display screens, in particular to a light emitting diode (Light Emitting Diode) display screen and an application thereof. Background technique [0002] In the prior art, the LED display is usually composed of a plurality of lamp beads, which are combined by plugging. Among them, the packaging methods of the lamp bead products are mainly surface mount device SMD (Surface Mounted Devices) packaging and chip packaging. . However, SMD packaged products and Chip packaged products have size limitations. Among them, the current minimum size of SMD packaged lamp beads can only be 1.5mm*1.5mm, and the current minimum size of Chip packaged lamp beads can only be 0.8mm. *0.8mm, which limits the size of the LED display, resulting in the minimum dot pitch that the current LED display can achieve at 1.6mm, which hinders the use of LED displays in small-size, high-resolution fields, such as in the home environment Applications...
