Description

technical field

[0001] The present invention relates to the technical field of display devices, in particular to a display panel, a display device and a method for preparing the display panel. Background technique

[0002] With the continuous development of display technology, a Micro Light Emitting Diode (Micro-LED) display device has become an indispensable display device type. A micro light-emitting diode is a device with a size ranging from a few microns to hundreds of microns. Because it is much smaller than ordinary light-emitting diodes, it is possible for a single micro LED to be used as a pixel for display. A Micro LED display is a display that uses a high-density Micro LED array as a display pixel array to display images.

[0003] At present, Micro LED displays mainly include two parts: a light-emitting substrate and a color filter substrate. The Micro LEDs are aligned on the light-emitting substrate, and the color filter substrate is provided with color resists ...
