Abstract

The invention discloses a full-color Micro-LED display device based on quantum dots in glass and a preparation method of the full-color Micro-LED display device. The device mainly comprises a glass machine body, a Micro-LED light-emitting device array and a Micro-LED driving chip from top to bottom, the Micro-LED light-emitting device array is mainly formed by arranging a plurality of Micro-LED light-emitting devices at intervals in an array mode, the Micro-LED light-emitting devices are all electrically connected and packaged on the Micro-LED driving chip, and quantum dot light-emitting units distributed in an array mode are arranged in the glass machine body. The quantum dot light-emitting units are generated by direct writing induction of ultrafast laser in the glass body, and the quantum dot light-emitting units in the glass body have different light-emitting wavelengths. The prepared full-color Micro-LED display device is smaller in size and lower in cost, and the problem that the stability of a perovskite material is poor is solved.

Description

technical field [0001] The invention belongs to the application field of semiconductor lighting and a color display device and a preparation method in the field of display devices, and relates to a full-color Micro-LED display device based on laser-induced quantum dot precipitation inside glass and a preparation method thereof. Background technique [0002] With the continuous development of information technology, the requirements for low power consumption, high color gamut, high brightness, high resolution display and lighting technology are also increasing, and a new generation of Micro-LED technology has emerged. At present, the preparation process of monochrome Micro-LED is relatively mature, and the method of inkjet printing and atomization spraying is mainly used to coat the surface of Micro-LED chip with quantum dot material. However, for full-color multi-color Micro-LED display devices, the size of a single color unit of these methods is limited, and it is inevitabl...
