Abstract :
As the size and resolution of LCD TVs increases, the merits of the temporal division driving method (TDM), which can replace pixel-division technology, have become more important because of the difficulty in packing multiple subpixels into a high-resolution panel. However, several image-quality issues in TDM panels (such as flicker and moving artifacts) limit the adoption of TDM technology in LCDs. In this paper, we propose a method to overcome the drawbacks of the TDM method using pixel dithering, and we investigate the image-quality improvement of the new method using subjective image-quality assessments. We also determine the optimum conditions for enjoying the best performance of LCDs with TDM technology. This demonstration shows that high-resolution TV is capable of adopting TDM technology .
