Abstract:
A method for driving an active matrix organic light-emitting diode (AMOLED) display. The method may be used to digitally drive the AMOLED display in a way that limits the susceptibility of the AMOLED display to certain problems arising out of digital driving techniques, such as image sticking or low display lifetimes. The method involves generating compensation factors corresponding to each pixel of the display and using those compensation factors to control the illumination of the display. The aspects of the method that incorporate the operation point for generating a compensation factor may also be applied to analog driving of AMOLED displays.

Claim (Index 1):
A method for driving an active matrix organic light-emitting diode (AMOLED) display, the AMOLED display comprising a plurality of organic light-emitting diodes (OLEDs) arranged in a plurality of rows and a plurality of columns; a plurality of pixel circuits each configured to drive an OLED, and arranged in a plurality of rows and a plurality of columns; a scan line for selecting the pixel circuits of each row of pixel circuits and a data line for controlling the pixel circuits of each column of pixel circuits; and a plurality of supply lines connected to the anodes and cathodes of the AMOLED pixels; wherein the method comprises:\n measuring, with an electronic unit, an electrical property of one or more OLEDs, each of the one or more OLEDs being a component of an OLED pixel, each of the OLED pixels having a current efficiency value; calculating, with a processor, a compensation factor against the drift of the current efficiency of the one or more OLED pixels based on the electrical properties measured; adjusting, based on the compensation factor of the one or more OLED pixels, one or more pixel gray values of the one or more OLED pixels, wherein the adjustment of the one or more pixel gray values further depends on an operation point of an OLED in the OLED pixel; applying a data signal to the pixel circuit based on the adjusted pixel gray value; and wherein the adjusted pixel gray value of the OLED pixel is generated based on the amplitude of the current fed to the pixel circuit.
