Abstract

The embodiment of the invention provides a light emitting diode, a display substrate, a transfer device and a method thereof. The transfer device comprises an adsorption carrier plate for bearing andadsorbing a display substrate; a scattering structure which splashes a plurality of light emitting diodes to the display substrate; a vibration mechanism which drives the adsorption carrier plate to vibrate, so that the magnetic butt joint points of the light emitting diodes are adsorbed on electromagnetic blocks of the display substrate; and an alignment mechanism which drives the light emittingdiodes to deflect and be aligned by taking the magnetic abutting points as axes. According to the invention, the magnetic butt joint points are arranged on the light emitting diodes in advance; an electromagnetic block is arranged in each sub-pixel of the display substrate; the electromagnetic blocks in the sub-pixels adsorb the magnetic butt-joint points of the light-emitting diodes through the vibration of the adsorption carrier plate; the light emitting diodes are driven to deflect and be aligned by taking the magnetic butt joint points as the axes, so that accurate alignment of the light emitting diodes is realized, and the problems of inaccurate alignment, low yield, long transfer time, high production cost, unsuitability for large-scale mass production and the like in the prior art are effectively solved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a light emitting diode, a display substrate, a transfer device and a method thereof. Background technique [0002] Light Emitting Diode (LED) technology has been developed for nearly three decades, from the initial solid-state lighting power supply to the backlight source in the display field and then to the LED display screen, providing a solid foundation for its wider application. With the development of chip manufacturing and packaging technologies, sub-millimeter light emitting diode (Mini Light Emitting Diode, Mini LED) display and micro light emitting diode (Micro Light Emitting Diode, Micro LED) display have gradually become a hot spot of display panels. Among them, Micro LED display has significant advantages such as low power consumption, high color gamut, ultra-high resolution, and ultra-thin, and is expected to become a better display technology to replace Organic Lig...
