Abstract
A method of driving a diode type display unit in which a charge regulating period is added to driving signal waveform in order to regulate amount of charge in a display picture element capacitor in the display unit wherein a two-terminal element having nonlinear current-voltage characteristics is provided two-dimensionally on a substrate, an electrooptical element capable of controlling the optical quality by means of applied voltage is disposed in response to the two-terminal element, charge is injected into the electrooptical element by utilizing the current-voltage nonlinearity in the two-terminal element for writing period, and the charge injected is held by utilizing the current-voltage nonlinearity in the two-terminalelement for holding period thereby effectig display.
