Abstract
An organic electroluminescence display that drives a display panel by a digital driving scheme. The organic electroluminescence display includes: a data driver that supplies a data signal in units of subframes to the display panel; and a power supply that supplies a high-potential voltage to the display panel, wherein the power supply that varies the high-potential voltage supplied to subpixels of the display panel for each subframe.
Claims8
An organic electroluminescence display that drives a display panel, the organic electroluminescence display comprising:
- a data driver that supplies a bit value of a data signal to a subpixel in units of subframes to the display panel at different times for different scan lines depending on a scan signal;
- and
- a power supply that supplies a high-potential voltage to the subpixels of the display panel,
- wherein the high-potential voltage has different voltage levels for different subframes and luminance differences for the bit value within the same subframe with subpixel position on the display are compensated by varying the bit value for each subframe for each subpixel pixel position on the display panel power supply varies the high-potential voltage supplied to subpixels of the display panel for each subframe.
A driving method of an organic electroluminescence display that drives a display panel, the method comprising:
- supplying a data signal in units of subframes to the display panel;
- and
- supplying a high-potential voltage to the display panel and varying the high-potential supplied to subpixles of the display panel for each subframe,
- wherein, in the supplying of the data signal, luminance differences within the same subframe are compensated for by varying the bit value of the subframe for each subpixel position on the display panel.
