Abstract:
A display panel is provided. The display panel includes a plurality of light-emitting diodes constituting a plurality of sub-pixels of the display panel and configured to be divided into a plurality of groups; and a plurality of LED driving circuits configured to: receive a PWM data voltage in a scanning period; and based on the PWM data voltage, drive the plurality of light-emitting diodes by providing drive current to the plurality of light-emitting diodes for a time corresponding to the PWM data voltage in an emission period, wherein each of the plurality of LED driving circuits is configured to be connected to light-emitting diodes included in respective groups of the plurality of groups, and drive the light-emitting diodes of the respective groups.
