In a power supply device of the invention, when the state of charge SOC1 of a low-voltage battery is lower than a discharging reference value Shi1 below a full charge level and when the state of charge SOC2 of a high-voltage battery is not lower than a discharging reference value Slow2 at a system-off time, the low-voltage battery is charged close to its full charge level with the electric power supplied from the high-voltage battery. The lead acid battery used for the low-voltage battery has the high potential for deterioration in the continuously low state of charge SOC. The lithium secondary battery used for the high-voltage battery has the high potential for deterioration in the continuously high state of charge SOC. The charge of the low-voltage battery in combination with the discharge of the high-voltage battery enables both the low-voltage battery and the high-voltage battery to have respective favorable states of charge with little potentials for deterioration. The technique of the invention thus effectively prevents quick deterioration of both the low-voltage battery and the high-voltage battery.

A display device includes a substrate, a display portion formed on the substrate, an upper layer which covers the display portion, and a gas barrier layer provided between at least a part of the substrate and the display portion. The gas barrier layer is positioned near to the position which forms a neutral plane when bending moment in a direction in which the substrate is warped acts on the overall display device.

A radar device can reliably, and rapidly detect dirt adhered to a radome surface without misdetection. The radar device includes a transmit / receive shared antenna (306) that transmits an electric wave to an object and receives a reflected wave that has been reflected from the object, a mixer (307) that mixes a transmission signal and a reception signal together to generate a beat signal, and a signal processing unit (312) that measures a distance to the object and a relative speed of the object on the basis of the beat signal. The transmit / receive shared antenna (306) modulates an unmodulated wave into a pulse and transmits the pulse modulated wave at a specific timing. In the case where the unmodulated pulse is transmitted, the beat signal that has been generated by the mixer (307) is converted into a digital voltage value by an A / D converter (310). The signal processing unit (312) detects the dirt that is adhered to the radome (314) of the transmit / receive shared antenna (306) on the basis of an output of the A / D converter 310.

An organic light emitting diode (OLED) display comprises: an OLED; a driving transistor for supplying driving current to the OLED; a data line for transmitting a corresponding data signal to the driving transistor; a first transistor having a first electrode connected to one electrode of the OLED and a second electrode connected to the data line; and a second transistor having a first electrode connected to the data line and a second electrode connected a gate electrode of the driving transistor, wherein the first transistor, the second transistor, and the driving transistor are turned on, a first current and a second current are respectively sunk in a path of driving current from the driving transistor to the OLED through the data line, and a threshold voltage and mobility of the driving transistor are calculated by receiving a first voltage and a second voltage applied to the gate electrode of the driving transistor corresponding to sinking of the first current and the second current through the second transistor and the data line, and the data signal transmitted to the data line is compensated.

In an image sensing apparatus, an image sensing unit generates image data formed via an optical member, a storage unit stores correction information for correcting deterioration of image quality of the image data, a reading unit reads correction information corresponding to a plurality of setting values close to a parameter used to control the optical member from the correction information stored in the storage unit, a conversion unit converts a pixel position of the image data to polar coordinates, a generation unit generates correction information by interpolating the read correction information, and a correction unit corrects the image data at the pixel position at the polar coordinates using the correction information. The storage unit stores correction information corresponding to more polar angles in a range having a greater degree of change in the deterioration of image quality in an angular direction centered on the optical axis of the optical member.
