Abstract:
An organic light emitting diode display device including: a display panel including a plurality of pixels, a scan driving unit configured to supply a scan signal to the pixels via a plurality of scan lines, a data driving unit configured to supply a data signal to the pixels via a plurality of data lines, an emission driving unit configured to supply an emission control signal to the pixels via a plurality of emission control lines, and a timing control unit configured to control the scan driving unit, the data driving unit, and the emission driving unit, and to control the emission driving unit to gradually change an off-period of the emission control signal each time a number of image frames are displayed.
Abstract:
A driving method for dimming an organic light-emitting diode (OLED) display is disclosed. In one aspect, the method includes selecting a dimming mode indicating a maximum luminance to be displayed by the OLED display based on an input and determining a luminance range from a plurality of luminance ranges. The determined luminance range comprises the maximum luminance of the dimming mode. The method also includes performing at least one of converting image data based at least in part on the dimming mode or controlling a duty ratio of an emission control signal, wherein the performing is based at least in part on the determined luminance range.

Abstract:
In a method of compensating gamma reference voltages includes setting a plurality of emission signal on-duty ratios that have different values in a range from 0% to 100%, setting a plurality of data offsets for the emission signal on-duty ratios and each of the data offsets being set based on a color shift, the color shift being caused according to the emission signal on-duty ratios, generating a plurality of compensation gamma reference voltages by multiplying a gamma reference voltage by the data offsets, and applying the compensation gamma reference voltages to an organic light emitting display panel in dimming ranges that include the emission signal on-duty ratios, respectively.
