Abstract

The invention discloses a display device and a manufacturing method of a monochrome micro light emitting diode, comprising: a first substrate and a second substrate oppositely arranged, monochrome micro light emitting diode devices arranged in an array on the first substrate, and a monochrome micro light emitting diode device located on the first substrate The two substrates face the quantum dot color film layer on one side of each monochrome micro light emitting diode device; each monochrome micro light emitting diode epitaxial sheet corresponds to each sub-pixel unit in the quantum dot color film layer. Since only single-color micro-LEDs are needed instead of three-color micro-LEDs, there is no problem of transferring a large number of various Micro LED chips, which can greatly reduce the low yield rate caused by the high difficulty of transfer. The problem. At the same time, only single-color micro-LEDs are used, and the service life and decay rate of each micro-light-emitting diode are consistent, so that the display color shift caused by the different lifespan and decay rate of Micro LEDs of different colors can be avoided.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display device and a method for manufacturing a single-color micro light-emitting diode. Background technique [0002] Micro Light-Emitting Diode (Micro LED for short) technology, that is, LED miniaturization and matrix technology. It refers to a high-density micro-sized LED array integrated on a chip, in which each LED can be addressed and driven to light up individually, reducing the pixel distance from millimeters to microns. The power consumption of Micro LED is only one-tenth of that of Liquid Crystal Display (LCD). Like Organic Light-Emitting Diode (OLED), it is self-illuminating, and its color saturation is close to that of OLED. The size and weight of Micro LED can be further reduced, and it has the characteristics of low power consumption and fast response, which has become the focus of research in this field. [0003] However, in the manufacturing process of the Mi...
