    摘要: An electroluminescence display device includes a controller which generates signals for controlling at least one pixel circuit during a first period and a second period. The controller controls current to a light-emitting element of the at least one pixel circuit based on a data voltage in the first period. The controller controls a supplying period of current to the light-emitting element based on a duty control voltage in the second period. The supplying period when the pixel circuit is driven at a first gray scale value is longer than that when the pixel circuit is driven at a second gray scale. The first gray scale value is greater than the second gray scale value.

    摘要: A device includes pixel circuits arranged in columns and rows, n data lines (n being an integer of 2 or more) for each column, gate lines supplied with scan signals, and light-emitting control lines supplied with light-emitting control signals. The pixel circuits are divided into n groups of rows, each group of rows being exclusively connected to a corresponding data line. Each pixel circuit includes a write control transistor to control writing a data voltage in response to a scan signal, a driving transistor to control the amount of current to be supplied to a current light-emitting element, a light-emitting control transistor to control supply of a current to the light-emitting element in response to a light-emitting control signal, a capacitor to retain a voltage corresponding to a write data voltage, and a reset transistor to set the gate electrode of the driving transistor with the initial voltage.

    摘要: An optoelectronic device includes a first transistor, a second transistor, and a control circuit. The first transistor is electrically connected between a power supply and a light-emitting element, has a gate to receive a gray scale voltage, and supplies the light-emitting element with a driving current corresponding to the gray scale voltage. The second transistor has a gate electrically connected to an electrode of the light-emitting element and a source or drain electrically connected to a circuit including a voltmeter. The control circuit reads a measurement value of the voltmeter when the gate of the first transistor receives the gray scale voltage, and corrects a next gray scale voltage applied to the gate of the first transistor based on the measurement value.
