Abstract

The application discloses a micro-light emitting diode transfer substrate and a transfer method, a display panel and a preparation method, which are used to simplify the process complexity of preparing a micro light-emitting diode device. An embodiment of the present application provides a transfer substrate for a micro light-emitting diode, the transfer substrate includes: a first base substrate and an electro-deformable layer located on the first base substrate; the electro-deformable layer is In: making the thickness of the electro-deformable layer in the region corresponding to the micro-light emitting diode that needs to be transferred each time be greater than the thickness of the electro-deformable layer in the region corresponding to the micro-light-emitting diode that does not need to be transferred this time.

Description

technical field [0001] The present application relates to the field of display technology, in particular to transfer substrates and transfer methods for micro-light emitting diodes, display panels and preparation methods. Background technique [0002] In recent years, research on the display of micro light-emitting diodes (Micro LEDs) has become a hot topic. Micro LED (Micro LED) is a device with a size between several microns and hundreds of microns. Because it is much smaller than ordinary LEDs, it is possible to use a single LED as a pixel (Pixel) for display. Micro An LED display is a display that uses a high-density Micro LED array as a display pixel array to display images. Each pixel can be addressed and driven to light up independently. It can be regarded as a reduced version of an outdoor LED display. Distances are reduced from millimeters to microns. At present, the Micro LED device needs to be grown on the supply substrate, and then the Micro LED is transferred ...
