摘要： A method for driving a PDP having a first electrode, a second electrode, and a panel capacitor formed therebetween. The method includes a reset period, an address period, and a sustain discharging period. In the reset period, a first voltage waveform falling from a first voltage to a second voltage is applied to the first electrode for a first period. Wall charges formed in the sustain discharging period are erased. A second voltage waveform rising from a third voltage to a fourth voltage is applied to the first electrode for a second period. A third voltage waveform falling from a fifth voltage to a sixth voltage which is lower than the second voltage is applied to the first electrode for a third period.

摘要： An improved plasma display panel (PDP) having decreased background brightness, decreased power consumption, and improved contrast is disclosed. In one embodiment, the PDP includes a driver that includes an address electrode, and a scan electrode and a sustain electrode are arranged in pairs with the address electrode. The PDP driver also includes a subfield data generator that generates subfield data from input image data. An address data driver is provided for applying to the address electrode a voltage that corresponds to the subfield data. An address data determiner included in the PDP driver detects a subfield which has no address data from among the subfield data, and outputs a control signal that controls a reset operation the detected subfield is driven. In response, a scan/sustain pulse driver applies to the scan electrode and the sustain electrode a voltage that corresponds to the control signal provided by the address data determiner.

摘要： The number of X electrodes of a PDP to be driven is m, the number of Y electrodes of the same is m+1, and they are alternately disposed at equal intervals. The intersections (2m−1) between all the X electrodes and Y electrodes and the data electrodes (n) form each cell, and a total of (2m−1)×n pixels exist. Wall charges with the same polarity and the same amount are formed on the X electrode and Y electrode within one cell while surface discharge occurs between the X electrode and Y electrode, and lighting and non-lighting is distinguished based on the wall charge amount. The surface discharge is set so as not to occur when either the X electrodes or Y electrodes only change their voltages.

摘要： An inexpensive and simple circuit for improving the quality of a dynamic image, with appropriate, flexible dynamic image qualities processing, even with plural input signal sources. A memory unit has a region for storing images of at least one screen, and a memory control unit for writing image data to the memory unit on the basis of a first clock and a first image synchronizing signal and for outputting image data read out from the memory unit on the basis of a second clock and a second image synchronizing signal. A clock generating unit provides the second clock, and a synchronizing control unit inputs the second clock and outputs the second image synchronizing signal. The synchronizing control unit generates one signal asynchronous to the first image synchronizing signal, by dividing the second clock, and another that is and synchronized with the first synchronizing signal, by using the second clock, and selects one of the signals it has produced to be output as the second image synchronizing signal. In a case of multiple input signals, then such fourth image synchronizing signals equal in number to the input signals are produced.

摘要： An image display device for displaying images by using the digital signal processing and by making use of the sight emission of the phosphor. An static image is detected from an image signal data, and when the luminance level of the static image is high, the luminance level of the specific area is lowered, and when the luminance level of the static image is low, the luminance level of the specific area is increased. In this manner, it is possible to reduce image retention of the static image when the static image is displayed for a long time.

摘要： According to a plasma display apparatus of the present invention, at least in one sub-field, a driving signal applied to retain data written in each pixel has a frequency applied first and a frequency applied thereafter, the frequencies being different from each other. The first frequency is controlled to be low and the frequency thereafter is controlled to be high, for example (two-frequency driving method). With a first low-frequency pulse, initial discharge in a sustaining period is started stably, and with a high-frequency pulse thereafter, the discharge is sustained. Use of the high-frequency pulse increases the number of light emissions, thus leading to improvement in brightness. Thus, the present invention enables both discharge stabilization and increase in brightness, and can therefore improve picture quality of the plasma display apparatus.
