Assignee: LG DISPLAY CO., LTD.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 9:
10. A display driving method of a display device including a display panel including a plurality of gate lines, a plurality of data lines, and a plurality of subpixels including a plurality of driving transistors, a gate driving circuit configured to apply scan signals to the plurality of gate lines, and a data driving circuit configured to convert image data into a data voltages and apply the data voltages to the plurality of data lines, the display driving method comprising:
determining a reference period of a recovery voltage, the reference period indicative of a timing which the recovery voltage is applied to at least one driving transistor of the plurality of driving transistors to reset the at least one driving transistor;
displaying an image on the display panel;
compensating the data voltages applied to the plurality of driving transistors based on sensed characteristic values of the plurality of driving transistors within a blank period of a frame period, the frame period including a display driving period during which the data voltages are applied and the blank period during which the data voltages are maintained; and
applying the recovery voltage to the at least one driving transistor a plurality of times within the blank period based on the reference period.
