The present invention provides a switch capable of reducing the length in the height direction. According to the present invention, there is provided a switch comprising a switch portion having an operating surface and a circuit board having an electrode, wherein the electrode is configured to be capable of detecting an operation on the switch portion, a component mounting surface of the circuit board is arranged nonparallel to the operating surface and the thickness of the circuit board does not exceed the height of the switch portion.

Switch and display device

Provided is a liquid crystal display device that can further reduce flicker. The liquid crystal display device includes a control unit that controls the luminance of a backlight using PWM dimming. The backlight includes n (n&#x2265;4) number of backlight blocks that are turned on at different timings, and the n number of backlight blocks are turned on in an order different from the order in which the backlight blocks are physically arranged.

A mask used in a dual pyroelectric sensor and configured to allow the pyroelectric sensor to accurately detect a movement of a moving object in each of the disposition direction of two pyroelectric elements and a direction perpendicular to the disposition direction. The mask is applied to the sensing surface of the dual pyroelectric sensor to increase the sensitivity with which the pyroelectric sensor detects a moving object. The mask includes a sheet configured to block infrared rays and an aperture pattern including through holes formed in the sheet. The aperture pattern is formed in such a manner that the percentages of the respective infrared-irradiated ranges of the two pyroelectric elements of the pyroelectric sensor vary with a movement of a moving object in each of x- and y-directions.

An anode ripple voltage waveform is detected by a capacitor built into a flyback transformer. The detected waveform is then phased by a phasing circuit, amplitude adjusted by an amplitude adjusting circuit and subsequently delivered to an addition circuit. A horizontal component is detected by a horizontal output transformer, then phase adjusted by a phasing circuit and subsequently amplitude adjusted by an amplitude adjusting circuit. Thereafter, the horizontal component is added to the anode ripple component by the addition circuit, inverted and amplified by an inverting amplifier, and then supplied to an antenna arranged in proximity to the cathode ray tube. Thus, electric fields radiated from the face of the cathode ray tube are suppressed.
