Abstract: The self-lighting subpixels of a display device are ones whose output luminances are functions of analog drive voltages applied to the subpixels and corresponding digital grayscale command signals used for controlling the subpixels. The display device generates corresponding analog dimming values and digital dimming values in accordance with supplied current limiting parameters and generates control value signals using the analog dimming values and the digital dimming values. It also changes the original grayscale digital data values of input video signals of one frame in accordance with the digital dimming values.

Abstract: An organic light emitting display and a driving method of the organic light emitting display capable of reducing or minimizing power consumption. The driving method includes setting a number of selection times constituting one frame, and setting a number of unit times constituting the one frame. Each of the unit times includes j (j is a natural number of 2 or more) of the selection times. Scan signals are non-sequentially supplied to scan lines during each of the unit times. The one frame includes a number of subframes. Data signals for ones of the subframes having a same length are supplied corresponding to i (i is a natural number of 2 or more) consecutive ones of the scan signals.
