    摘要： A display apparatus permitting high resolution and a large number of gray-scale levels and causing indiscernible flicker has been disclosed. One frame is divided into or composed of j subframes, and light is produced according to a luminance level predetermined subframe by subframe in order to express intermediate gray-scale of a picture. Emphasis is put on the fact that display to be performed during each subframe within one frame can be controlled independently. An interlaced-scanning display is carried out during k subframes associated with low-order weighted bits out of j subframes, and a noninterlaced-scanning display is carried out during the other j-k subframes associated with high-order weighted bits. The ratio of an addressing scan time to a subframe associated with a small weight is large, and the ratio of an addressing scan time to a whole frame is very large. If the addressing scan time can be reduced as mentioned above, a great effect would be exerted. Moreover, the luminance levels to be determined in relation to the subframes during which interlaced-scanning display is carried out are so low that the influence of the reduction on a whole picture is limited.

    摘要： An electrode drive circuit performs interlaced scanning, ensuring that the phases of the sustaining pulse in odd-numbered lines and even-numbered lines among L1 to L8 between surface discharge electrodes are the reverse of each other. With this, when either odd-numbered lines or even-numbered lines are displayed, the voltages applied between the electrodes of the undisplayed lines are at 0, eliminating the necessity for partitioning walls on the surface discharge electrodes. In surface discharge electrodes, X electrodes are provided on the two sides of a Y electrode and the area between the Y electrode and the X electrode on one side is assigned a display line at an odd-numbered frame, and the area between the Y electrode and the X electrode on the other side is assigned a display line in an even-numbered frame. Alternate areas between the surface discharge electrodes are assigned as blind lines and a discharge light emission in the blind lines is blocked or incident light to the blind lines from the outside is absorbed. Address electrodes are provided for each monochromatic pixel column and selectively connected with the pads above them, performing simultaneous selection of lines.

    摘要： A method of actuating a PDP device uses an actuating pulse signal which comprises an erasing mode for erasing data displayed on a display panel, a writing mode for writing new data on the panel and a sustaining mode for sustaining a state of displaying the data. The data to be displayed are input by an input signal which is not synchronized with the actuating pulse signal. At and before the time of changing the mode of the actuating pulse signal, at least one pulse is eliminated from the actuating pulse signal.

    摘要： Discharge spots on a display device can be shifted by using the primary current effect. For the purpose of shifting the discharge spots, electrodes with a right angle to a shift direction are connected periodically to a plurality of buss to which a series of sustaining signals are supplied in a predetermined time differences. This function of shifting the discharge spots can simplify the peripheral circuit of the display device and also increase a domain of the application of this kind of display device, such as a plasma display panel.
