Abstract
A display module includes a plurality of pixels; a substrate; a plurality of inorganic LEDs arranged on the substrate, each of the plurality of pixels including two or more inorganic LEDs among the plurality of inorganic LEDs; and a plurality of micro-pixel controllers two-dimensionally arranged in a first direction and a second direction on the substrate, each of the plurality of micro-pixel controllers being configured to control two or more pixels among the plurality of pixels. Each micro-pixel controller of the plurality of micro-pixel controllers is electrically connected to micro-pixel controllers adjacent thereto, and is configured to convert a voltage input from one of the micro-pixel controllers that is electrically connected thereto in a direction opposite to the first direction into a target voltage and supply the target voltage to another micro-pixel controller of the micro-pixel controllers that is electrically connected thereto in the first direction.
