Abstract:
The disclosure provides a micro light-emitting diode display panel. The array substrate is arranged with a plurality of pixels in an array. Each of the pixels at least includes a subpixel of three colors. Each of the subpixels is disposed with at least one μLED chip corresponding to color of the subpixel. Bin levels of the μLED chips of the subpixels with the same color in two adjacent pixels are different and a difference of peak wavelengths >2 nm. The disclosure further provides a manufacturing method, the μLED chips with the corresponding color in the subpixel of the array substrate are transfer printed from the transfer printing plate to corresponding subpixels. The color and the bin level of the μLED chips in each transfer printing are identical. Bin levels of the μLED chips in the sub-pixels with the same color in two adjacent pixels are different.
