Abstract

A display module includes: a module substrate; a plurality of pixels provided on the module substrate; and a plurality of micro-pixel controllers provided in spaces between the plurality of pixels and configured to supply a drive current to at least two pixels among the plurality of pixels, where each micro-pixel controller of the plurality of micro-pixel controllers includes a pixel circuit configured to, based on a first voltage and a second voltage being applied to the micro-pixel controller, control an amplitude of the drive current based on the first voltage and control a pulse width of the drive current based on the second voltage, and, based on the display module being in a power saving mode, the first voltage is adjusted to decrease a brightness of a pixel in a specified region, among the plurality of pixels.
