technical field
[0001] The invention relates to a hot air head for transferring micro-light emitting diodes (Light Emitting Diode, LED) and a micro-LED transfer printing system using the same. Background technique
[0002] Currently, liquid crystal display (LCD) is still the mainstream in the display market, but Organic Light Emitting Diode (OLED) is rapidly replacing LCD and gradually becoming the mainstream. Recently, as display companies are actively participating in the OLED market, micro (Micro) light-emitting diode (hereinafter referred to as "micro LED") displays are gradually becoming the next-generation display. The core raw materials of LCD and OLED are liquid crystal (Liquid Crystal) and organic materials, respectively. On the contrary, micro-LED display is a display that uses LED chip itself as a light-emitting material in micron (μm) units.
[0003] Since the Cree company applied for a patent on "micro-light-emitting diode arrays that increase light output" (Ko...
