ABSTRACT:
A dynamic scattering matrix LCD, which requires a low expenditure of electric power without deteriorating contrast even when it is used for a high speed response STN liquid crystal display, includes a plurality of data line transparent electrodes, a plurality of scanning line transparent electrodes, data line drivers which selectively supply one of two levels of a first voltage signal to each of the data line transparent electrodes according to contents of a display image, scanning line drivers which selectively supply one of three levels of a second voltage signal to each of the scanning line transparent electrodes according to a control signal, and a voltage supply circuit which supplies the first voltage signal to the data line drivers and the second voltage signal to the scanning line drivers. The voltage supply circuit produces the two levels of the first voltage signal from two predetermined voltages without boosting the two predetermined voltages, and produces the highest and lowest levels of the three levels of the second voltage signal by boosting the two levels of the first voltage signal.
