The research team has developed a full-color, vertically laminated Micro LED with a resolution of up to 5,100 ppi and a size of only 4μm, claiming to have the highest array density and smallest size known to date. The features of high resolution and small size of the product suit the application requirements of near eye micro display electronic equipment.

The research results further promote the development and application of laminated Micro LED structure, and also arouse the LED industry's attention to this technical solution.

Specifically, the special feature of this scheme is that compared with the single pixel formed by the traditional parallel arrangement structure of RGB Micro LED chips, the application of the stacking arrangement scheme can reduce the size of the display module while improving the picture quality and production efficiency of the Micro LED display.

In particular, the laminated structure allows a single pixel to occupy less space, thus achieving a higher pixel density per unit area, thus meeting the application requirements of microdisplay devices for small size, high-definition display modules.

In terms of production, because of the application of the laminated structure, RGB three-color chips are integrated into a single chip, which shortens the transfer time of the Micro LED chip to the substrate and improves the placement accuracy, thus optimizing the production efficiency and cost of the Micro LED display.
