Abstract

The present disclosure relates to a display device. The display device comprises a plurality of light emitting units, a circuit mainboard and a processing unit. Each light emitting unit comprises an insulating body, a substrate, a light emitting chip, a driving chip and a pin. The two ends, opposite to each other, of the insulating body are respectively recessed to form a first groove and a secondgroove. The substrate is arranged in the insulating body. The light emitting chip is fixedly arranged on the substrate, and the light emitting chip is exposed out of the first groove. The driving chip is fixedly arranged on the substrate, and the driving chip is exposed out of the second groove. The first groove is filled with light-transmitting colloid. The second groove is filled with packagingcolloid. Each light emitting unit is fixedly arranged on the circuit mainboard. The processing unit is fixedly arranged on the circuit mainboard, the processing unit is electrically connected with the light emitting units, and the processing unit can control the brightness or color temperature of the light beams emitted by each light emitting unit independently. The display device in the invention can be used for solving the problems that the production cost of the circuit mainboard of the existing high-density display device is high and the related circuits of the circuit mainboard are complex.

Description

technical field

[0001] The invention relates to a display device, especially a display device with high-density LEDs. Background technique

[0002] Existing high-density display equipment is to arrange a plurality of LED units and related driving chips on a circuit board. Due to the huge number of LED units, the corresponding number of driving chips is also very large, thus having a circuit board. The circuit design is complicated and the production cost is high.

[0003] In addition, in order to reduce the circuit complexity and production cost of the circuit board, some manufacturers will make a single driver chip drive multiple LED units at the same time. This design can slightly reduce the circuit complexity of the circuit board. When any one of the LED units jointly driven by the driver chip is damaged, multiple LED units may fail to operate together; or, when any driver chip is damaged, multiple LED units may fail to operate at the same time.
