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.

摘要： In a liquid crystal display device, both of the brightness characteristic and the chromaticity characteristic are set to optimum values. In the liquid crystal display device which includes a liquid crystal display panel, a data driver, a scanning driver and a display control circuit, the display control circuit includes a first circuit which generates insertion display data which differs from the image display data and inserts the display data into the data driver, and a second circuit which sets a first time at which the scanning signal for displaying the display data and a second time at which the scanning signal for displaying the insertion display data are outputted. The first circuit generates display data of one chromatic color and, at the same time, sets gradations of chromatic color for every frame period.

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.
