Results correlating observed crosstalk-induced color artifacts as a function of the four signal-driving schemes used in high-resolution color thin-film-transistor liquid crystal displays (TFT/LCDs) are presented and theoretically explained. Experimental characterization has been carried out on a high- resolution 146-dot-per-inch, 262K-color, 5.5-in.-diagonal, 480 × 640-pixel (VGA) display. Mathematical modeling and simulations have been developed that help explain the crosstalk-induced color artifacts. The modeling is particularly advantageous for quantifying various tradeoffs between front-of-screen quality and signal-driving schemes when scaling pixel density toward higher-resolution TFT/LCDs.
