We have done a lot of work to study the surface noise of the panel due to the strict requirement of active stylus. During the research, we find that the surface noise occurs at the moment the mux circuits switch on, and the magnitude of positive noise is strongly dependent on what the panel display, in other words, the noise may have a strongly dependent on the data signal. Also the behavior of noise is consistent with that of common electrode. Then we established a circuit architecture to simulate the behavior of common electrode and found that the coupling of the data line on the common electrode would cancel each other out over a period of time while the existence of the mux circuits which breaks this balance. And based on this knowledge, we have done a lot of useful exploration and achieved good results.

A 13.3-in. UHD LTPS TFT-LCD with MUX3 by 15Hz driving was demonstrated in this paper. Since the high mobility of LTPS TFT and good design rule, the aperture ratio could be improved 28% compared to a-Si. By 15Hz driving, the logical power can be saved 34%. The total power of 13.3-in. UHD TFT-LCD could be lower to 2.7W by LTPS technology. The cell border could be easily down to 1.0mm by small TFT design and the down border could be down to 6.8mm with two 1932ch IC by MUX3 design.
