Method and apparatus for driving an amoled with variable driving voltage

摘要

The sharpness impression when displaying a movement on an AMOLED (Active Matrix Organic Light Emitting Display) shall be improved. For this purpose, an apparatus for driving a cell of an AMOLED is provided including driving means (14, 16) for applying a driving voltage to the cell and for applying a luminance control signal to the cell during a pregiven time frame. The apparatus further includes controlling means (17, 18) for varying the driving voltage within the time frame according to a predefined function of time. For example, the driving voltage may be varied in the form of a triangle so that the lighting time over the frame is reduced while a CRT like behavior is emulated.
