摘要： A video signal processing circuit is disclosed. The video signal processing circuit includes a difference detection section, first calculation section, and correction amount addition section. The difference detection section detects a difference between a drive voltage for each of pixels of a matrix drive type display panel as a pixel under consideration and a drive voltage of each of pixels adjacent to the pixel under consideration from an input video signal. The first calculation section calculates a correction amount of a drive voltage for a pixel under correction that has a luminance change due to an electric field caused by a difference of the drive voltages for the two pixels detected by the difference detection section. The correction amount addition section corrects a value of the drive voltage for a pixel under correction that has the luminance change based on the correction amount calculated by the first calculation section.

摘要： A liquid-crystal display device performs a feedback process. A video signal is written on pixels on a unit by unit basis, each unit including a plurality of pixels (six pixels, for example). Scan pulses output from RGB LCD panels are supplied to a driver IC that supplies the RGB LCD panels with a variety of timing signals. A delay amount from the scan pulses from the optimum state thereof is measured. The delay amount is accounted for in a pulse that samples and holds the video signal, i.e., a pulsewidth control clock pulse.

摘要： A first expansion valve is provided in an outdoor unit, and a second expansion valve is provided in an indoor unit. A pipe line connects a first joint pipe of the first expansion valve and a second joint pipe of the second expansion valve. When a refrigerant flows in from the second joint pipe and flows out from the first joint pipe, the first and second expansion valves are in a full open state due to pressure of the refrigerant. When the refrigerant flows in from the first joint pipe and flows out from the second joint pipe, the first and second expansion valves are in semi-closed state (flow rate controlling state). In a cooling mode, the second expansion valve expands the refrigerant just before an indoor heat exchanger, and in a heating mode, the first expansion valve expands the refrigerant just before an outdoor heat exchanger. In both heating and cooling mode, a large amount of refrigerant flows through the pipe line to reduce pressure loss.
