摘要:
A display and its driving method is provided in which the image signal can be input into a panel having a smaller number of rows than the number of scan lines for the image signal, without producing image distortion. For example, a signal of the PAL system having more rows is displayed on a display for the NTSC having less rows. The signal control is made such that an image signal is written in two rows at every horizontal scan, except for a particular image signal, but the particular image signal is written in one row. Normally, the image signal for every horizontal scan is written in two rows, but only a particular image signal for every horizontal scan is compressed and displayed in one row. Accordingly, the vertical resolution is not degraded, unlike the scan for thinning out the image signal.

A drive circuit for a color display device comprising a plurality of pixels which are wired in matrix through a plurality of data signal lines and a plurality of scanning signal lines; the drive circuit comprising an input means for sampling three-primary color image signals for one line which are inputted through three input lines during a given period t, to write the signals in a memory, and an output means for reading the three-primary color image signals during a certain t/2 period to output the signals to three output lines, and reading the three-primary color image signals during an additional t/2 period different from the certain t/2 period to output the signals to the three output lines. When the drive circuit is used in, e.g., an active matrix liquid-crystal display device, display can be free of flicker and can be in a high resolution.

A display apparatus is constructed to make a plurality of light beams of mutually different colors incident to a display element and modulate the beams of the respective colors by the display element to form images of the respective colors. Purity of a predetermined color out of the colors is variable and a control pattern of the image display element is modified according to variation in the purity of the predetermined color.

An inlet/outlet pipe extending downward from a bottom face of a body for a ladle is bent at its tip end into an S-shape in an intermediate portion of the pipe, and its tip end is located at a level higher than that of the bent portion. When a negative pressure in the ladle body is increased, a height of range of a molten metal is increased before and after an occurrence of disturbance in the ladle body, so that the negative pressure in the ladle body is made balance with a weight of the molten metal. Thereby, the molten metal is measured and held at a constant volume in the ladle body.

A display apparatus includes a CPU, an image display device, a light source for irradiating the image display device, a circuit for turning on/off the light source, a means for determining the resolution of the input image signal, a first switching means for turning on/off the power supply to the circuit components except the light source turning on/off circuit and a second switching means for turning on/off the power supply to the light source turning on/off circuit. In a first power-saving mode, the circuits may be opened by means of the first switching means after an appropriately selectable first predetermined period of time and may be opened by means of the second switching means after an appropriately selectable second predetermined period of time. A second power-saving mode is also provided for opening the first and second switching means by a combination of the polarity of the input horizontal synchronizing signal and that of the input vertical synchronizing signal. The first power-saving mode and the second power-saving mode may be used selectively.
