Abstract

The present invention provides a display device and a manufacturing method thereof. The manufacturing method of the display device includes the following steps. Array substrates are provided. The array substrate includes a plurality of sub-pixel areas, and each sub-pixel area includes first and second component areas. A first transposition process is performed to respectively place N first light-emitting elements in the first element regions of the N sub-pixel regions by using the first carrier. A second transposition process is performed to respectively place X second light-emitting elements in the second element regions of the X sub-pixel regions through the second carrier. A third transposition process is performed to respectively place Y second light-emitting elements in the second element regions of the Y sub-pixel regions by using the third carrier. The X sub-pixel regions do not overlap with the Y sub-pixel regions, and the N sub-pixel regions partially overlap with the X sub-pixel regions and the Y sub-pixel regions respectively.

Description

technical field [0001] The present invention relates to a display device and its manufacturing method, and in particular to a light-emitting diode display device and its manufacturing method. Background technique [0002] Light-emitting diodes have the advantages of high energy conversion efficiency, short response time, and long service life. Therefore, in recent years, light-emitting diodes have become the main lighting source with both power saving and environmental protection features. Furthermore, due to the breakthrough in the size of the LED, a technology of micro LED display (micro LED display) that directly places the LED in the pixel structure gradually appears on the market. [0003] The method of transposing the LEDs from the wafer to the array substrate may include stamp imprinting or electrostatic imprinting. Generally speaking, multiple transposition steps are required to place LEDs in all pixels (sub-pixels). The current transposition process includes disp...
