Implementation of Optical Response of Thin Film Transistor with Verilog-A for Mobile LCD Applications

In this paper, a contribution of Verilog-A to the optimum design of liquid crystal displays (LCDs) is presented. The Verilog-A module for estimating the photo-leakage current was attached to a built-in thin film transistor (TFT) model as an independent instance. Sufficient accuracy, desired speed, and good computational stability have been obtained for LCD design. This plug-in approach can facilitate to implement some additional effects to a built-in model already provided in commercial circuit simulators.
