Abstract
Micro light-emitting diode (LED) displays and assembly apparatuses are described. In an example, method of manufacturing a micro-light emitting diode (LED) display panel includes positioning a display backplane substrate in a tank or container, the display backplane substrate having microgrooves therein. The method also includes adding a fluid to the tank or container, the fluid including a suspension of light-emitting diode (LED) pixel elements therein. The method also includes moving the fluid over the display backplane substrate. The method also includes assembling LED pixel elements from the fluid into corresponding ones of the microgrooves.
