A micro-LED display panel includes a pixel array that includes a plurality of pixels arranged in a plurality of rows and columns, wherein each pixel of the pixel array includes a blue LED, a green LED, and a red LED. The display further includes a frame buffer and a bitplane generator. The bitplane generator is configured to receive display data from the frame buffer and to output a color updating schedule according to the display data. The color updating schedule updates a luminance and a color of the display data for each pixel in the pixel array during each of a plurality of time intervals that define a frame time of a frame. The color updating schedule row-shifts and frame-rotates at least one row of the frame.

Exemplary processing methods include forming a group of LED structures on a substrate layer to form a patterned LED substrate. A light absorption barrier may be deposited on the patterned LED substrate. The methods may further include exposing the patterned LED substrate to light. The light may be absorbed by surfaces of the LED structures that are in contact with the substrate layer, and the light absorption barrier. The methods may still further include separating the LED structures for the substrate layer. The bonding between the LED structures and the substrate layer may be weakened by the absorption of the light by the surfaces of the LED structures in contact with the substrate layer.
