    Abstract: A MEMS microphone includes a diaphragm having conductivity, first and second variable capacitors respectively including first and second fixed electrodes, a first voltage output section that outputs a first voltage changed according to a change in a capacitance of the first variable capacitor, and a second voltage output section that outputs a second voltage changed according to a change in a capacitance of the second variable capacitor. The first and second fixed electrodes face the diaphragm. The capacitances of the first and second variable capacitors are changed in accordance with a vibration of the diaphragm. A first bias voltage is applied to the first fixed electrode. A reference voltage is applied to the second fixed electrode. A second bias voltage is applied to the diaphragm. A difference between the second bias voltage and the reference voltage is half of a difference between the first bias voltage and the reference voltage.

  • Publication number: 20070222738
    Abstract: Provided is a display device (100) which predicts a predicted temperature difference between a peripheral display area and an outer peripheral area of a display section (200) based on an input image signal from an image-signal input section (10). When the predicted temperature difference is a set reference value or more, the display device (100) controls luminance of an image displayed on the peripheral display area so as to be lowered. Therefore, the predicted temperature difference is predicted by using only the input image signal, and the luminance of the image displayed on the peripheral display area can be appropriately controlled without performing a calculation using the predicted temperature difference. Hence, such a luminance control for preventing breakage of the display section (200) can be easily performed.
