The invention discloses an LED display screen. The LED display screen comprises an LED display screen substrate, an LED wafer, a first joint element and a second joint element. The LED display screen substrate is provided with a drive circuit, the output end of the drive circuit comprises a first positive electrode and a first negative electrode, and the first positive electrode and the first negative electrode are located on the first surface of the LED display screen substrate. The LED wafer is located on the first surface, the input end of the LED wafer comprises a second positive electrode and a second negative electrode, the second positive electrode and the second negative electrode are located on the second surface of the LED wafer, and the second surface and the first surface are arranged in opposite. The first positive electrode and the second positive electrode are jointed and electrically connected through the first joint element, and the first negative electrode and the second negative electrode are jointed and electrically connected through the second joint element. The LED display screen solves the technical problem that due to the size limitation of a support in traditional packaged lamp beads, the minimum point space of an LED display screen is over large.
Description
technical field [0001] The present invention relates to the field of display screens, in particular to a light emitting diode (Light Emitting Diode) display screen. Background technique [0002] In the prior art, the LED display is usually composed of a plurality of lamp beads, which are combined by plugging in. 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. [0003] At t...
