    摘要： This sensor state determination system is a sensor state monitoring system capable of accurately determining whether or not a detecting sensor used with a railroad vehicle is in an abnormal state. This system includes: a detecting sensor capable of detecting a physical value acting upon the railroad vehicle; and an electronic control device. A monitoring sensor equivalent to the detection sensor is installed at a position equivalent to the position of the detection sensor. The electronic control device is provided with a determination means (coherence calculation section, state determination section) that computes, based on a first signal detected by the detecting sensor and a second signal detected by the monitoring sensor, a coherence value indicating a correlation between the signals. The electronic control device determines that the detecting sensor is in an abnormal state if the coherence value is smaller than a preset abnormality determination value.

    摘要： The present invention provides an image display device comprising data lines each supplying a data signal, and a plurality of pixel circuits. Each of the pixel circuits includes a light-emitting element, a capacitor which stores a difference in potential caused by the data signal therein, a drive transistor which has a gate electrode connected to the data line via the capacitor and controls light emission of the light-emitting element based on a difference in potential between the gate electrode and a source electrode thereof, which is generated by a potential supplied by the data line and the potential difference stored in the capacitor, and a variation control switch which causes the difference in potential between the gate and source electrodes of the drive transistor to vary based on the data signal at the turning on thereof and prevents the difference in potential from varying at the turning off thereof.

    摘要： The present invention provides a driving method for a display device which includes a display part having pixels of M columns×N rows and a memory, wherein each pixel includes a light emitting element and a driving transistor for driving the light emitting element. At times other than a usual light emitting time, a driving voltage is applied to the driving transistor of each pixel so as to turn on the light emitting element of each pixel, a value of current which flows in the light emitting element of each pixel is detected, correction data for each pixel is calculated based on the detected value of current, and the calculated correction data for each pixel is stored in the memory. At the usual light emitting time, a driving voltage which is based on data which is obtained by adding the correction data stored in the memory to video signal data is applied to the driving transistor of each pixel.

    摘要： The present invention overcomes image defects such as the brightness inclination or smears by reducing the line resistance of a power source bus line which supplies electricity to organic EL elements. A plurality of pixels which are arranged in a matrix array is connected to power source lines, and the plurality of power source lines are connected to a power source bus line. Both ends of the power source bus line are connected to a power source part via a FPC. By supplying electricity to both ends of the power source bus line from the power source part, the line resistance of the power source bus line can be reduced.
