摘要:
An excitation hole is provided inside a dielectric block and, on the outer surface of the dielectric block, an input-output terminal electrically connected to an inner conductor inside the excitation hole is formed at one end portion of the excitation hole. A grounding-electrode-free portion is provided on the surface opposite to an input-output electrode of a mounting substrate with which the input-output terminal makes contact. Thus, the electric field strengths in upward and downward directions toward an outer conductor of the dielectric block from the excitation hole are balanced to suppress spurious TE-mode signals, etc.

A display has a display panel of a first aspect ratio and is able to display on the display panel an image of a second aspect ratio whose width element is larger than that of the first aspect ratio. The display has a gate driver, a data driver, and a timing controller. The gate driver sequentially selects gate lines of the display panel. The data driver stores data for one gate line and supplies the data to one of the gate lines selected by the gate driver. The timing controller supplies control signals to the gate and data drivers so that predetermined data is displayed in top and bottom non-image areas of the display panel during a vertical blanking period. The display is capable of displaying images of different sizes.

A display device includes a display panel having display pixels arranged in matrix formation. A first driver circuit sequentially supplies image data to vertical lines of the display panel in synchronism with a first clock signal. A second driver circuit sequentially drives horizontal lines in synchronism with a second clock signal. A control circuit controls a drive timing at which the second driver circuit sequentially drives the horizontal lines so that identical image data equal to one horizontal line is supplied, from the first driver circuit in synchronism with the first clock signal, to two consecutive horizontal lines every N horizontal lines (N is an integer) in accordance with an enlargement ratio at which an image is enlarged in a vertical direction and is displayed on the display panel.

A dielectric resonator apparatus comprising at least three quarter-wavelength dielectric coaxial resonators in a dielectric block is provided. In the dielectric resonator apparatus, an outer conductor is formed on the surfaces of the dielectric block, and a pair of input and output electrodes for capacitively coupling with the two dielectric coaxial resonators located at both ends is formed close to a first end surface of the dielectric block on a predetermined side surface of the dielectric block so as to be electrically insulated from the outer conductor. Further, two capacitance coupling electrodes for capacitively coupling with the two dielectric coaxial resonators, respectively, which are selected among at least three dielectric coaxial resonators and are located apart from each other so as to put another one dielectric coaxial resonator therebetween, are formed on the predetermined side surface of the dielectric block so as to be electrically insulated from the outer conductor and so as to be apart from the first end surface by a predetermined length. The two capacitance coupling electrodes are electrically connected through a bypass electrode.
