Abstract:
A Micro LED color display device is provided, which uses a second blue LED (B 2 ) with a short wavelength to excite a green-color-conversion layer (G) to replace a green LED (P 2 ) in green sub-pixels. The second blue LED (B 2 ) itself is more stable, the chromaticity of the green color is controlled by controlling the accuracy of the coating thickness of the green-color-conversion layer (G). The accuracy of the coating thickness is easily controlled than the specification of the green LED, and hence, the chromaticity uniformity is better, the stability of the green color is easy to control, and the display quality is improved.

Claim (Index 11):
A Micro LED color display device, comprising a driving substrate, a package substrate disposed opposite to the driving substrate, a plurality of blue sub-pixels, green sub-pixels, and red sub-pixels arranged in an array arrangement between the driving substrate and the package substrate, and a support disposed between the driving substrate and the package substrate; an LED is disposed in each of the sub-pixels;\n the blue sub-pixels comprising a first bottom-pixel electrode disposed on the driving substrate, a first top-pixel electrode disposed opposite to the first bottom-pixel electrode, and a first blue LED interposed between the first bottom-pixel electrode and the first top-pixel electrode and emitting blue light of a first wavelength; the green sub-pixels comprising a second bottom-pixel electrode disposed on the driving substrate, a second top-pixel electrode disposed opposite to the second bottom-pixel electrode, a second blue LED interposed between the second bottom-pixel electrode and the second top-pixel electrode and emitting blue light of a second wavelength that is different from the first wavelength, and a green-color-conversion layer interposed between the second top-pixel electrode and the package substrate; the red sub-pixels comprising a third bottom-pixel electrode disposed on the driving substrate, a third top-pixel electrode disposed opposite to the third bottom-pixel electrode, and a LED interposed between the third bottom-pixel electrode and the third top-pixel electrode; wherein in the red sub-pixel, the LED interposed between the third bottom-pixel electrode and the third top-pixel electrode is a red LED; wherein the blue sub-pixels further comprise a first transparent spacer disposed between the first top-pixel electrode and the package substrate, and the red sub-pixels further comprises a second transparent spacer disposed between the third top-pixel electrode and the package substrate; wherein the green-color-conversion layer is selected from green quantum dots; wherein the first blue LED has a first height and the red LED has a second height, and wherein a height of the first transparent spacer and a height of the second transparent spacer are the same or different, a sum of the first height of the first blue LED and the height of the first transparent spacer and a sum of the second height of the red LED and the height of the second transparent spacer are the same.
