摘要
A drive signal for an LCD panel is formed of pulses having a raised cosine shape. Such pulse shape results in a drive signal having minimal harmonic content. The resulting drive signal is less susceptible to low pass filter, signal degradation effects. Regarding STN displays, the degradations which do occur are readily correctable amplitude and phase variations. Regarding TFT panels, the reduced harmonic content, in turn reduces coupling between adjacent panel circuits.
