Abstract
A display module is provided. The display module includes a plurality of sub-pixel circuits, each sub-pixel circuit including: an inorganic light-emitting diode, a transistor connected in parallel with the inorganic light-emitting diode, and a pulse width modulation (PWM) circuit configured to control a light-emitting time of the inorganic light-emitting diode by controlling a voltage of a gate terminal of the transistor based on an applied PWM data voltage that is applied to the PWM circuit; and a pulse amplitude modulation (PAM) circuit which is connected in series with an inorganic light-emitting diode of one of the plurality of sub-pixel circuits, the PAM circuit being configured to provide a driving current having a constant amplitude to the inorganic light-emitting diodes, wherein the inorganic light-emitting diodes of the plurality of sub-pixel circuits are connected in series to each other.
