This paper proposes a new method to determine the overdrive (OD) values using a behavioral circuit model. Based on the accurate prediction of overdriven transitions in the behavioral circuit model, the proposed method enables us to obtain the OD values easily. The proposed method requires only three OD values to complete all the OD values. The estimated OD values agree with the measured OD values. The average OD deviation was only 1.60 over all data transitions. Index Terms-Behavioral circuit model, liquid crystal display overdrive (OD), response time.

“…For LCDs, overdrive (OD) technology is commonly used to improve the slow response characteristics of liquid crystals [3]. This is achieved by applying higher or lower voltages when data transitions occur [3]. In the proposed driving waveform, the two additional voltage levels fulfil the role of the OD technology.…”

Abstract. This paper proposes a temperature-dependent behavioral circuit model to predict the optical characteristics of an active-matrix liquid crystal display with a fringe-field switching (FFS) mode. The optical responses of liquid crystal displays (LCDs) are strongly affected by their ambient temperature. We optimized the time-constant parameters that describe the movement of liquid crystal molecules so that simulated optical responses of FFS LCD provide the best fit to the measured responses over the temperature range of 0 to 50°C. It is found that these time-constant parameters have a linear relationship with the ambient temperature, which enables the prediction of optical responses at any given temperature. The simulation results of the transient responses show an excellent match with the measured results regardless of the ambient temperature. © The Authors.
