Classification: CPC G | IPC G

Claim 15:
16. A display device comprising:
a display panel including a plurality of subpixels, a plurality of gate lines, a plurality of data lines, and a plurality of driving transistors each included in a corresponding subpixel from the plurality of subpixels;
a data driving circuit configured to convert image data into data voltages and apply the data voltages to the plurality of data lines during a display driving period of a frame period that includes the display driving period and a blank period during which the data voltages are maintained;
a timing controller configured to switch operation of the display device between a first driving frequency and a second driving frequency that is different from the first driving frequency,
wherein a recovery voltage is applied to at least one driving transistor of the plurality of driving transistors a first plurality of times according to a predetermined timing during a first blank period of a first frame period that corresponds to the first driving frequency, and
wherein the recovery voltage is applied to the at least one driving transistor a second plurality of times according to the predetermined timing during a second blank period of a second frame period that corresponds to the second driving frequency where the second blank period has a duration that is different from the first blank period.
