Abstract

The present invention provides a display panel, which includes a transparent substrate, has a display area and a fan-out area, and a plurality of small-sized Micro LED display units are arrayed in the display area to form a large-sized Micro LED display by splicing. panel, and the side walls of adjacent MicroLED display units are closely attached to each other, so that the seamless splicing of MicroLED display units can be realized, and the transparent metal lines and fan-out wiring connecting the MicroLED display units are all transparent materials, so that large-size The MicroLED display panel is capable of transparent display. Moreover, the present invention transplants a large number of MicroLED light-emitting units onto the transparent substrate, but forms a large-sized MicroLED display panel by splicing a plurality of small-sized MicroLED display units, thereby improving the transfer yield and assembly efficiency.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel. Background technique [0002] Compared with OLED displays, Micro LED displays have high reliability, high color gamut, high brightness, high transparency, and high pixel density (PPI); and low packaging requirements, it is easier to achieve flexible and seamless splicing display, and it has great potential for development in the future. For future displays, especially the transparent display part, due to the small size of MicroLED, the chip area can only account for less than 1% of the pixel area. For example, the size of the MicroLED chip is 15um*15um, and the pixel size is 250um*250um. 1% of the pixel area, and through the optimized design of the pixel, an aperture ratio of more than 80% can be achieved, thereby displaying a Micro LED display with high transparency and high pixel density (PPI). The large-scale application of high-resolution and high-transpare...
