Image Quality Improvement in LCDs With Temporal Division Method Using Pixel Dithering

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 .
