Method to control a matrix display screen and device for implementation of said method |
摘要 |
Method for controlling a matrix display screen enabling its contrast to be adjusted as regards a liquid crystals screen and its luminosity as regards a fluorescent micropoints screen, said method consisting of periodically applying line conductors addressing signals V1 having for a certain period a value Vmax into an absolute value to be applied to column conductors of control signals. Addressing signals are applied to the line conductors, the durations of said signals having a value Vmax and are partially recovered for two consecutive lines.
