Abstract

According to the present specification, provided is a micro LED display device. The micro LED display device includes a substrate, a supply voltage line on the substrate, and a micro LED area disposed on the supply voltage line. At least one portion of the supply voltage line is disposed at the vertical lower part of the micro LED area.

Claims (16)

1 . A micro light emitting diode (LED) display device comprising:

a substrate;

a supply voltage line disposed on the substrate;

a micro LED area disposed on the supply voltage line, and

a thin film transistor (TFT) array disposed between the supply voltage line and the micro LED area,

wherein at least one portion of the supply voltage line is disposed directly below the micro LED area.

2 . The micro LED display device of claim 1 , wherein the supply voltage line is divided into a plurality of portions,

wherein the device further comprises an insulating layer disposed between adjacent portions of the supply voltage line.

3 . The micro LED display device of claim 1 , wherein the micro LED area includes four sub-pixels per a single pixel,

wherein the four sub-pixels are respectively disposed in first to fourth quadrants.

4 . The micro LED display device of claim 3 , wherein the four sub-pixels include three sub-pixels corresponding to R, G, and B, respectively, and a remaining one sub-pixel corresponding to one of R, G, or B.

5 . The micro LED display device of claim 3 , wherein spacings between the four sub-pixels and the supply voltage line are equal to each other.

6 . The micro LED display device of claim 5 , wherein a width of the supply voltage line is greater than a spacing between adjacent ones of the sub-pixels.

7 . The micro LED display device of claim 5 , wherein a width of the supply voltage line is smaller than a width of the micro LED area.

8 . The micro LED display device of claim 3 , wherein a pixel circuit area is disposed on each of both opposing sides of the micro LED area within a single pixel.

9 . The micro LED display device of claim 1 , wherein the supply voltage line acts as a data line.
