The invention discloses a light emitting diode display screen. The display screen comprises an LED display screen substrate, on which an LED driving circuit is arranged. An output terminal of the LED driving circuit comprises a first positive electrode and a first negative electrode. The display screen further comprises LED wafers positioned on a first surface, a first joint part, a second joint part and a physic material layer. Input terminals of the LED wafers comprise second positive electrodes and second negative electrodes. The first positive electrode and the second positive electrodes are joined and connected electrically via the first joint part. The first negative electrode and the second negative electrodes are joined and connected electrically via the second joint part. The physic material layer is arranged on the LED wafers and comprises at least one of following materials such as smoothing material, film-coating material, thin film material and fluorescent material. The light emitting diode display screen helps to solve the technical problem in the prior art that the spacing distance between minimum points of the LED display screen is overlong by restrictions of the size of a support for lamp beads during a packaging process.
Description
technical field [0001] The invention relates to the field of display screens, in particular to a light emitting diode display screen. Background technique [0002] In the prior art, LED display screens are usually composed of a plurality of lamp beads, which are assembled by plugging. Among them, the packaging methods of 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 the current stage, the size limitati...
