Abstract

The present invention provides a display device and a method of manufacturing the same. The manufacturing method of the display device includes the following steps: providing an array substrate that includes a plurality of sub-pixel regions, each of the pixel regions includes first and second component regions; performing a first transposition process to respectively place N first illumination components in the first component regions of the N sub-pixel regions by a first carrier; performing a second transposition process to respectively place the X second illumination components in the secondcomponent regions of the X sub-pixel regions by a second carrier; performing a third transposition process to respectively place the Y second illumination components in the second component regions of the Y sub-pixel regions by a 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 Ysub-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...
