摘要： Provided are a power supply circuit and a display device which are capable of enhancing power efficiency even when applied to a display panel whose current consumption varies. The power supply circuit boosts and outputs an input voltage using a booster chopper circuit. A frequency control circuit changes a frequency of a clock signal, which controls a switch of the chopper circuit, in accordance with a load of the power supply circuit. The frequency control circuit divides an operation of the display device into a display effective period at a high load and a vertical retrace period at a low load, based on a vertical synchronizing signal and a horizontal synchronizing signal. The frequency control circuit sets the frequency of the clock signal in a high-load period to be higher than that in a low-load period.

摘要： In a seat, a bass acoustic vibration transmission section and a treble acoustic vibration transmission section are arranged distinctively with respect to a seat occupant, such that those two acoustic vibration transmission sections are disposed independently of each other, thereby achieving both of the following two effects: an acoustic performance worthy of acoustic seat; and a seating comfort essentially required as a seat.A vibration conduction unit is provided, which comprises a combination of: one bass speaker; a support plate to which that one bass speaker is secured; and a network cushion member of three-dimensional structure arranged on an anterior surface of the support plate. Such vibration conduction unit is disposed and accommodated in a cut-out region defined in a seat padding to a predetermined extent of covering an area of seat back which corresponds to a lumbar part of seat occupant, whereas on the other hand, a pair of treble speakers are respectively provided in a pair of local areas of the seat padding which correspond respectively to left-side and right-side shoulder portions of seat back, such that each of those two local areas of seat padding has an opening defined therein, wherein the opening lies anteriorly of an output side of each of the two treble speakers.

摘要： A liquid crystal driver of liquid crystal display device in which a plurality of expansion/contraction ratios of display data, for example, two kinds of expansion/contraction ratios can be set in a register is provided. Further, the two kinds of expansion/contraction ratios are applicable respectively in two kinds of areas (still-image and video-image) whose coordinates are previously set in a liquid crystal panel. As a result, it is possible to make the still-image area and the video-image area have different expansion/contraction ratios of pixel value respectively. In this manner, it is possible to make display brightness high only in the video-image area, thereby realizing both lower power consumption and visibility improvement at the same time.

摘要： Method of and apparatus for converting a first two-dimensional image on first column direction and row direction scales to a second two-dimensional image on second column direction and row direction scales at a high speed, in which use is made of the periodicity of the positional relation between the image elements of the first image arranged in matrix and having various data values and the image elements of the second image arranged in matrix and having various data values to determine, for each one of the second image elements, four second image elements lying on the intersections between two adjacent rows and two adjacent columns in the first image element matrix which rows and columns surround the second image element and constitute a reference from for the second image element, and in which the data value for each second image element is calculated on the basis of the data values of the four first image elements associated with the first image element and the vertical and horizontal coordinates within the reference frame. Both of the above-mentioned periodicity and the coordinates are defined in terms of the ratios between the first and second scales for the first and second two-dimensional images, i.e., magnifications.
