Abstract

The invention discloses a mass transfer device and transfer method of a miniature light-emitting diode, and relates to the field of light-emitting display. The mass transfer device comprises a miniature light-emitting diode array groove plate (1) and a miniature light-emitting diode component (2), wherein the miniature light-emitting diode component (2) is placed in a miniature light-emitting diode groove (11) of the miniature light-emitting diode array groove plate (1), a horizontal air blowing device (3) and a vertical air blowing and oscillation device (4) are arranged below the miniature light-emitting diode array groove plate (1), a detection device (5) is arranged above the miniature light-emitting diode array groove plate (1), the miniature light-emitting diode array groove plate (1) comprises a substrate layer (100), a driving circuit layer (101) and a protection layer (102). By the mass transfer device and transfer method of the miniature light-emitting diode, no transfer toolis needed, and simple process, high yield, high transfer accuracy and low cost are achieved.

Description

technical field [0001] The invention relates to the field of light-emitting display, in particular to a mass transfer device and transfer method of micro light-emitting diodes. Background technique [0002] Micro light-emitting diode (Micro LED) is a display technology that miniaturizes and matrixes the traditional LED structure, and uses CMOS integrated circuit technology to make a driving circuit to realize the addressing control and individual driving of each pixel. Since the brightness, life, contrast, response time, energy consumption, viewing angle and resolution of micro light-emitting diodes are stronger than those of LCD and OLED technologies, and they are self-illuminating, simple in structure, small in size and energy-saving. Advantages, it has been regarded as the next generation of display technology by many manufacturers and has begun to actively deploy it. A core technical problem faced by micro-LEDs in the process of industrialization is the Mass Transfer te...
