摘要： An active matrix electroluminescent display device comprises an array of display pixels (10) which each include a current-driven electroluminescent display element (20) connected to a driving device (22) controlling the current flowing through the display element in a drive period according to a voltage stored on a capacitance (36) and determined by a data signal applied in a preceding address period. In order to compensate for ageing effects in the display element, electro-optic devices (45, 40) are included in the pixel for adjusting the voltage stored on the capacitance in dependence on the light output of its display element during the address period.

摘要： In an active matrix system, a pixel of a display apparatus includes an electroluminescence (EL) element, a diode type driving element connected in series to the EL element for driving the EL element, an added capacitor and an added resistor. The added resistor is connected in series with the added capacitor, and the added resistor and the added capacitor are connected in parallel to the EL element.

摘要： A method and apparatus for driving a plurality of addressable elements consist of driving and selectively enabling one or more addressable elements arranged as an M.times.N array using two drivers. A first and a second driver are used to drive first and second signals at slightly different frequencies on a first and a second display conductor. A plurality of pixels, coupled between the first and second display conductors, is addressed according to a pixel location in which the first signal is approximately in phase with the second signal. The pixel scan rate is proportional to the difference between the first and second signal frequencies. The first and second conductors may contain a plurality of delay elements and tap-off points. Conducting lines may be terminated by their characteristic impedance to prevent any reflection of the traveling signals. The periods of the first and second signals may be greater than or approximately equal to a propagation delay of between first and last tap-off points on the first and second conductors, respectively. The pulse width of the first and second signals may be less than or approximately equal to a propagation time of the first and second signal between adjacent tap-off points on the first and second display conductors, respectively. The matrix display pixels are selectively enabled by modulating an amplitude of the first signal and/or an amplitude of the second signal when the selected pixel location(s) is addressed so that the voltage differential between the first and second signals is sufficient to enable the addressed pixel.

摘要： A liquid crystal display apparatus includes systems of voltage applying devices for applying voltages to a liquid crystal and a controlling device for switching among these systems. The systems of voltage applying devices each have at least one non-linear switching element, and the controlling device has a memory portion for storing the switched state. With such a construction, electric power loss caused by one signal line having a relatively high frequency can be avoided by using another signal line having a relatively low frequency, thereby allowing a white, black, or gradation display with reduced power consumption.

摘要： A method of driving a pixel element an active matrix display. The method inducing a change of the bias voltage of the first transistor towards its threshold voltage with an essentially constant current provided from the semiconductor channel of a field effect transistor to cause the bias voltage of the first transistor linearly depend upon the time lapse since the light-emitting element starts to emit light. The method also includes terminating light emitted from the light-emitting element after the bias voltage of the first transistor becomes substantially close to the threshold voltage of the first transistor.
