Abstract

A display device based on a miniature LED relates to the technical field of semiconductor electronic devices, solves the problem that a miniature LED display device capable of being produced on a large scale is needed in the prior art, and comprises a control unit, a movement mechanism and a miniature LED display unit. The miniature LED display unit is connected with the movement mechanism, the control unit is connected with the movement mechanism and the miniature LED display unit, and the control unit enables the miniature LED display unit to display and enables the movement mechanism to move. According to the display device based on the miniature LED, through the control unit and the movement mechanism, the original miniature LED unit with the dead pixels can work normally, and the miniature LED display unit with the dead pixels can be put into application without adopting a dead pixel repairing means. The manufacturing cost of the miniature LED display device is reduced, the manufacturing time is shortened, and a technical foundation is laid for productization of the miniature LED.

Description

technical field [0001] The invention relates to the technical field of electronic devices made of semiconductors, in particular to display devices based on micro LEDs. Background technique [0002] Due to its high resolution, high brightness, high contrast, high refresh rate, low power consumption, long life and other advantages, micro LED display devices are regarded as a new generation of display technology following LCD and OLED displays. [0003] However, there is a technical bottleneck in the preparation process of micro-LED display devices-mass transfer technology. That is, how to form an effective electrical connection between millions of LED chips and the driving circuit to achieve a 100% success rate. If there are dead pixels in the micro-LED chip, it is necessary to adopt a method of repairing the dead pixels, which not only prolongs the production cycle, but also increases the cost of the product. Therefore, micro-LED display chips have not yet formed a large-sc...
