Title: Liquid crystal display device
Inventor: KAMIYA KIYOSHI
IPC: G09G3/36
Filed: 1992-05-26
Abstract: PURPOSE:To provide the liquid crystal display device with small size, excellent control performance and high picture quality. CONSTITUTION:A television signal 100 is sampled and stored in an analog memory 104. Data are read from the analog memory in matching with a timing of a scanning signal from a scanning electrode drive circuit 107 and outputted to a comparator 105. The comparator 105 compares the data with a reference waveform from a reference waveform generator 101 to convert the data into a signal subjected to pulse width modulation. The modulation signal is outputted to a drive waveform generating section 109, in which a signal electrode drive signal subjected to AC processing and temperature compensation or the like is generated and outputted to a signal electrode of a liquid crystal display panel and a picture based on a television signal is displayed on the liquid crystal display device. Since the analog signal is modulated into a consecutive pulse width, high picture quality display without quantization noise is obtained. Furthermore, since a binary signal is used for a liquid crystal drive waveform, the control performance is excellent.
