摘要： A method of manufacturing an organic electroluminescence display includes preparing a substrate including pixels. The pixels each include a drive transistor and a capacitor. The capacitor of a subject pixel is caused to hold a voltage which corresponds to a threshold voltage of the drive transistor, and the voltage is read. A first signal voltage is obtained by adding a first correction parameter of the subject pixel to a second signal voltage corresponding to a single gradation level belonging to an intermediate gradation region or a high gradation region of representative voltage-luminance characteristics. The first signal voltage is applied to the driver of the subject pixel, and a luminance emitted by the subject pixel is measured. A second correction parameter with which the luminance emitted by the subject pixel becomes a standard luminance is calculated.

The current corresponds to a voltage held in the capacitor. A first switch is between the capacitor and a data line, and the data line supplies the voltage to the capacitor. A voltage detector is connected to the data line for detecting an anode voltage applied to the organic EL element. A second switch is between the anode and the data line. A controller turns on the first switch, causes the organic EL element to emit light, and causes the voltage detector to detect the anode voltage by turning off the first switch and turning on the second switch while the organic EL element is emitting light.

摘要： A display device is provided which includes a luminescence element, a data line, and a switch connected between an electrode of the luminescence element and the data line. A voltage generation circuit supplies a pre-charge voltage to the data line. A current generation circuit supplies an inspection current to the electrode of the luminescence element plural times through the data line and the switch. A voltage detection circuit detects, the plural times, voltage values of the electrode supplied with the inspection current. When a difference between the voltage values is at least a predetermined value, the voltage generation circuit supplies the data line with an updated voltage that is higher than the pre-charge voltage.

摘要： A display device includes a luminescence element. A power line provides the luminescence element with an electric current. A capacitor accumulates a driving voltage corresponding to a data voltage. A driver flows the electric current according to the driving voltage accumulated in the capacitor through the luminescence element via the power line. A controller is configured to set a reverse bias voltage and an application time period according to an amount of luminescence produced by the luminescence element, and to determine luminance levels in luminescence periods. The controller sets the reverse bias voltage and the application time period according to a peak luminance of the luminance levels when a difference between the peak luminance and an average luminance of the luminance levels exceeds a predetermined threshold, and applies the reverse bias voltage for the application time period within an OFF period of the data voltage for removing an electric charge accumulated in the luminescence element. The OFF period is within one of the luminescence periods.

摘要： A display apparatus is provided which optimally restores decreased luminance and extends a life of a light emitting element. The display apparatus includes a memory that stores a plurality of trap levels in association with a plurality of use durations of the light emitting element. An obtainer determines one of the plurality of use durations of the light emitting element. A controller reads, from the memory, one of the plurality of trap levels associated with the one of the plurality of use durations, and removes a charge from the light emitting element by application of a reverse bias voltage having a level associated with the one of the plurality of trap levels. The controller changes the level of the reverse bias voltage which is applied to the light emitting element so that as the one of the plurality of use durations increases, the level of the reverse bias voltage increases.
