Abstract

The invention provides a micro LED display panel, by disposing a plurality of active areas ( 2 ) on the substrate ( 1 ) arranged in an array, and a plurality of micro LEDs ( 3 ) uniformly arranged in each active area ( 2 ), to achieve high-resolution of micro LED display panel, and by controlling the number of micro LEDs in each active area to effectively control the production cost, while eliminating the screen door effect, to enhance market competitiveness of micro LED display panel.

Claims (17)

1. A micro light-emitting diode (LED) display panel, which comprises: a substrate and a plurality of active areas disposed on the substrate and arranged in an array, with each active area disposed with a plurality of micro LEDs uniformly distributed with intervals;

wherein each active area is rectangular; and

wherein each of the active areas belonging to an odd-numbered column, odd-numbered row and the active areas belonging to an even-numbered column, even-numbered row comprises five micro LEDs, with four disposed at the four corners of the active area and one disposed at the center of the active area; and

each of the active areas belonging to an odd-numbered column, even-numbered row and the active areas belonging to an even-numbered column, odd-numbered row comprises four micro LEDs, with four disposed respectively at the mid-point of four sides of the active area.

2. The micro LED display device as claimed in claim 1 , wherein the micro LEDs in the active areas of the same row have the same light color, and the micro LEDs in the two neighboring active areas have different light colors.

3. The micro LED display device as claimed in claim 2 , wherein for a positive integer M, the light color of the micro LEDs in the active areas of the (3M−2)-th row is red, the light color of the micro LEDs in the active areas of the (3M−1)-th row is green, and the light color of the micro LEDs in the active areas of the 3M-th row is blue.

4. The micro LED display device as claimed in claim 1 , wherein the micro LEDs are manufactured by micro transfer printing.

5. A micro light-emitting diode (LED) display device, which comprises: a substrate and a plurality of active areas disposed on the substrate and arranged in an array, with each active area disposed with a plurality of micro LEDs uniformly distributed with intervals;

wherein each active area is rectangular;

wherein each active area comprises nine micro LEDs, arranged in a 3×3 array;

wherein two neighboring micro LEDs in the same active area have different light colors; and

wherein the light colors of the micro LEDs in the three rows of the first column of each active area are red, green and blue sequentially; the light colors of the micro LEDs in the three rows of the second column of each active area are green, red and blue sequentially; and the light colors of the micro LEDs in the three rows of the third column of each active area are blue, green and red sequentially.

6. The micro LED display device as claimed in claim 5 , wherein the micro LEDs are manufactured by micro transfer printing.

7. A micro light-emitting diode (LED) display device, which comprises: a substrate and a plurality of active areas disposed on the substrate and arranged in an array, with each active area disposed with a plurality of micro LEDs uniformly distributed with intervals;

wherein each active area is rectangular;

wherein each active area is disposed with four micro LEDs, with the four micro LEDs disposed respectively at the mid-point of the four sides of the active area, wherein the two opposite sides have red micro LEDs at mid-point, and the remaining two opposite sides have a green micro LED and a blue micro LED respectively at mid-point.

8. The micro LED display device as claimed in claim 7 , wherein the micro LEDs are manufactured by micro transfer printing.
