Abstract

The present disclosure relates to a method for manufacturing a display device, and one particular implementation relates to a substrate chuck for self-assembling micro LEDs. The substrate chuck may include a first frame having a hole at a central portion thereof, a second frame having a hole at a central portion thereof and disposed to overlap the first frame, a frame moving part configured to transfer the second frame such that the second frame presses the substrate while the substrate is disposed between the first and second frames, and an auxiliary clamp configured to additionally press the second frame toward the substrate while the second frame is pressing the substrate.

Description

technical field [0001] The present disclosure relates to a method for manufacturing a display device, and one particular embodiment relates to a substrate chuck for self-assembling micro-LEDs. Background technique [0002] In recent years, in the field of display technologies, liquid crystal displays (LCDs), organic light emitting diode (OLED) displays, micro LED (microLED) displays, and the like have been competing to realize large-area displays. [0003] In contrast, when semiconductor microLEDs (μLEDs) with a diameter or cross-sectional area of ​​less than 100 micrometers are used in displays, they can deliver very high efficiencies because the displays do not require polarizers to absorb light. However, large displays require millions of semiconductor light-emitting diodes, which makes transferring the devices difficult compared to other technologies. [0004] Some of the technologies currently being developed for transfer processes include pick-and-place, laser lift-of...
