Abstract

In this paper, we report an advanced anti-double edge overdriving method. This method overcomes artifacts from conventional overdriving schemes, such as double edge artifact, overshooting and undershooting. New artifacts also are reported and photo to explain the performance of our new algorithm. Edge oscillation artifact is reported in the paper for the first time. As we strongly overdrove the conventional feed backward overdriving method, these new artifacts occurred. Our advanced anti-double edge overdriving method successfully eliminates these artifacts and overdrives the spec of grayscale response to less than one frame time. IPS, MVA and fast TN LCD panels are all evaluated from commercial monitor to TV products by our new driving method. 8 ms grayscale switching performance over exact 8 bit to 8 bit transition can be achieved at 60 Hz frame rate.
