Title:
DRIVING METHOD OF LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
Japanese Patent JPH05100210
Kind Code:
A
Abstract:
PURPOSE:To provide a large gradation display number with a small number of voltages by applying different driving voltages to two picture elements which adjoin horizontally or vertically in the same frame. CONSTITUTION:The same picture elements (d) and (d') are applied with the different driving voltages at intervals of specific time (t) (t: integral multiple of display frame time). Consequently, the transmissivity of one picture element is averaged on the time base to display half-tones corresponding to the mean voltage of the two voltages (c). Further, two picture elements (a) and (b), or (a) and (c) which adjoin in both the directions of a display screen are applied with the different driving voltages, namely, the application order of the voltages is changed between the adjacent picture elements (c) to average the optical response of a liquid crystal cell on an internal surface.
