SUBFIELD DRIVING PIXELS IN A DISPLAY DEVICE

摘要

A method for driving pixels in a display device with an image signal is disclosed wherein the image signal comprises grey level information of an image to be rendered by the display device. The method comprises: dividing the image signal into sections, each section having a duration of a section period; dividing the section period into a plurality of adjacent, weighted sub-section periods; selecting for each of the pixels to be driven during the section period a sequence of adjacent sub-section periods in dependence on the grey level information, the selectable sequences lacking a common starting and ending point; driving the pixels during the sequences of adjacent sub-section periods. The method may be applied to displays driven by a pulse width modulated signal, such as sub-field as well as sub-line operated displays including plasma display panels, dynamic foil displays and passive displays.
