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.

We have developed one 13.3inch 4K2K (3840 x RGB x 2160) N-type polycrystalline silicon (LTPS) thin film transistor (TFT) panel used new active multiplexer driving configuration. The more efficiency by polarity swing voltage setting and two group bus line routing cause the panel which charge ability can be much better than traditional NMOS LTPS display with multiplexer driving.
