Abstract

The invention discloses a displayer for a micro-light-emitting diode and a manufacturing method thereof. The manufacturing method comprises the following steps that firstly, a light-emitting diode chip is formed on a supply substrate. Then, a first substrate is provided, and a printing circuit is arranged on the first substrate. Then, the supply substrate is reversely arranged on and covers the first substrate, and the light-emitting diode chip is attached to the printing circuit in an alignment mode. Then, the light-emitting diode chip falls off from the supply substrate. Then, the supply substrate is removed. Then, sol-gel glass is formed on the first substrate, and gaps among the light-emitting diode chips are completely filled with the sol-gel glass. Then, the second substrate is attached to the first substrate. According to the displayer for the micro-light-emitting diode and the manufacturing method thereof, the yield and reliability can be improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a micro light emitting diode display and a manufacturing method. Background technique [0002] A micro light emitting diode (Micro LED) is a component with a size ranging from a few microns to hundreds of microns. Since its size is only 1% of that of a normal light emitting diode, it makes a single micro light emitting diode as a pixel (Pixel) for display It is possible, and each pixel can be addressed and driven to emit light independently, and the distance between pixels can also be reduced from the original millimeter level to the micron level. [0003] A Micro LED Display (Micro LED Display) is a display that uses a high-density micro LED array as a display pixel array. Inheriting the characteristics of light-emitting diodes, the advantages of micro-light-emitting diodes include low power consumption, high brightness, ultra-high resolution and color saturation, fast respons...
