Abstract
The LED pixel includes a driver IC (20) and an LED chip (40); the LED chip (40) is stacked and mounted on a surface of the driver IC (20), and a wire (31) going from the cathode of the LED chip (40) is connected to the driver IC (20). The driver IC (20) is an unpackaged die. An insulation layer is disposed on the surface of the die, and a pad (30) disposed on the insulation layer is connected to a positive electrode. The LED chip (40) is mounted on the pad (30), and the anode of the LED chip (40) is electrically connected with the pad (40). This improves the light transmittance of the LED display product.
