摘要： A PDP driving circuit for a stable operation of a ramp pulse. A capacitor having a temperature characteristic opposite to a temperature characteristic of a part coupled to a switch that operates as a constant current source for generation of a ramp pulse is arranged in the driving circuit for generating a ramp pulse. The ramp pulse linearly increases or decreases a panel voltage of the PDP with respect to time. Parts having opposite temperature characteristics are coupled in parallel to control variation of a gradient of the ramp pulse so that values of the parts may not be varied depending on the temperature changes. Thus, stable operation of the ramp pulse is obtained.

摘要： A display device for displaying pictures by sequentially performing an address period and a sustain period, such as, a plasma display panel (PDP), is provided. The pixels of a panel are arranged into a plurality of groups, and an address period and a sustain period are sequentially performed on the pixels of individual groups. While an address period is being performed on the pixels of a certain group, the pixels of other groups are idle. While a sustain period is being performed on the pixels of the group subsequent to the address period, a sustain period is selectively performed on the pixels of each of other groups that have already undergone an address period. Accordingly, a sustain discharge operation is performed within a short period of time after an address operation is performed on each of the pixels, so that a stable sustain discharge occurs even though narrow scan pulses and address pulses may be applied during the address operation. Also, the time required to address all pixels is reduced.
摘要翻译：提供了一种用于通过顺序执行诸如等离子体显示面板（PDP）的寻址周期和维持周期来显示图像的显示装置。面板的像素被布置成多个组，并且对各个组的像素顺序执行寻址周期和维持周期。当正在对特定组的像素执行寻址周期时，其他组的像素是空闲的。当在寻址周期之后对组中的像素执行维持周期时，对已经经历了地址周期的每个其他组的像素选择执行维持周期。因此，在对每个像素执行地址操作之后，在短时间内执行维持放电操作，使得即使在地址操作期间可以施加窄扫描脉冲和寻址脉冲，也会发生稳定的维持放电。此外，减少寻址所有像素所需的时间。

摘要： A method and apparatus for driving a plasma display panel in which pairs of sustain electrodes lines respectively including X-electrode lines and Y-electrode lines that are alternately arranged parallel with each other are disposed to be orthogonal to address electrode lines, and discharge cells are defined by intersections between the sustain electrodes and the address electrode lines. In the method, a unit frame as a display period is divided into a plurality of subfields to realize time-division grayscale display, and the individual subfields include a reset period, an address period, and a sustain period. The method includes maintaining the Y-electrode lines at a reference level during the reset period and the sustain period; and addressing the Y-electrode lines by biasing the Y-electrode lines to a first level and simultaneously, sequentially applying a scan signal of the reference level to the Y-electrode lines during the address period.
