Led based display panel including common led driving circuit and display apparatus including the same

A method of operating a display panel including a plurality of light-emitting diodes constituting a plurality of sub-pixels, the method comprising:

• receiving, by a plurality of light emitting diode (LED) driving circuits, a pulse width modulation (PWM) data voltage in a scanning period;
• and
• based on the PWM data voltage, driving, by the plurality of LED driving circuits, the plurality of light-emitting diodes by providing driving current to the plurality of light-emitting diodes for a time corresponding to the PWM data voltage in an emission period;
• wherein the plurality of light-emitting diodes are configured to be divided into a plurality of groups, and
• wherein the plurality of LED driving circuits are 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.
