摘要： A method and apparatus for determining a vertical and horizontal (X-Y) target shot position on a Liquid Crystal or Plasma display screen may be adapted to connect to commercially available video game console systems. Upon a trigger event from a light gun when it is pointed at the target shot position, a blanking signal renders the monitor black during a first vertical refresh cycle. During a second vertical refresh cycle, the voltage to each of the red, blue and green channels is increased in three separate screen sections to create a display split between the three colours. The light gun is adapted to be capable of separately detecting a blue, red or green light pulse and the X-Y coordinates of the target shot position is determined on the basis of the colour detected by the light gun and the length of time which elapses between the start of the second vertical refresh cycle and the detection of the red, blue or green light pulse.

摘要： A method for driving plasma display panel is disclosed. The plasma display panel comprises a plurality of discharge units composed by a plurality of address electrodes, sustain electrodes and scan electrodes. Its driving method is characterized by using a set of sustain electrode control signals and a set of scan electrode control signals to apply pulse signals of predefined voltage to respectively a plurality of sustain electrodes and a plurality of scan electrodes over a predefined period of time during the sustain discharge period to enable them to alternately discharge and emit light, wherein during the sustain discharge period, either the scan electrode (Y electrode) or the sustain electrode (X electrode) is maintained at a constant potential and another electrode is used to generate the differential voltage required for alternate discharge between the sustain electrodes and scan electrodes to achieve the effect of continuous discharge and illumination. As such, the circuit design for the electrode having a constant potential may be greatly simplified, thereby offering the advantages of simplifying the driving waveform and lowering the circuit cost.
摘要翻译：公开了一种用于驱动等离子体显示面板的方法。等离子体显示面板包括由多个寻址电极，维持电极和扫描电极构成的多个放电单元。其驱动方法的特征在于使用一组维持电极控制信号和一组扫描电极控制信号，以在预定时间段期间在预定时间段内将预定电压的脉冲信号分别施加到多个维持电极和多个扫描电极维持放电期间使其能够交替放电发光，其中在维持放电期间，扫描电极（Y电极）或维持电极（X电极）中的任一个维持在恒定电位，另一电极用于产生维持电极和扫描电极之间的交替放电所需的差分电压，以实现连续放电和照明的效果。因此，可以极大地简化具有恒定电位的电极的电路设计，从而提供简化驱动波形并降低电路成本的优点。
