Display device and a method for driving the same

摘要

A method for driving a display device is disclosed. Display images of one frame are divided into detection regions; pixel polarity arrangements of each detection region are determined, and according to the determined result a data driving circuit selects a corresponding scanning method to drive the display device. The data driving circuit adopts an interlaced-to-progress scanning conversion method to drive the display device, so as to ensure that there are no data circuits in a loaded state, thereby reducing the power consumption of the display device.

1. A method for driving a display device comprising steps of: dividing display images of one frame into detection regions; determining pixel polarity arrangements of each detection regions; selecting a corresponding scanning method according to the determined result to drive the display device via a data driving circuit; wherein the step of determining pixel polarity arrangements of each detection regions comprises: determining whether each of the detection regions includes a first pixel polarity arrangement or a second pixel polarity arrangement; wherein the step of selecting a corresponding scanning method according to the determined result to drive the display device via a data driving circuit comprises: when it is determined that each of the detection regions does not include the first pixel polarity arrangement, then the data driving circuit drives the display device in a progressive scanning method; when it is determined that at least one detection region includes the first pixel polarity arrangement but the other detection regions do not include the second pixel polarity arrangement, then the data driving circuit drives the display device in an interlace scanning method; when it is determined that at least one detection region includes the first pixel polarity arrangement and at least one detection regions includes the second pixel polarity arrangement, then the data driving circuit drives the display in an interlaced-to-progressive scanning conversion method.
