Logic waveform generator cicuit

采用max+plusII电路设计软件和FPGA实现可编辑的逻辑波形产生电路,与高压驱动电路相结合实现了可编辑的高压脉冲序列产生电路,使不同结构或同一结构不同参数的显示屏可以共享一套电路系统,降低PDP研发成本,缩短研发周期。实验表明,采用同步电路设计的波形产生电路,工作稳定,输出波形光滑无“毛刺”。

In this paper a revisable logical waveform generation circuit based on FPGA is presented with the use of this logical circuit combined with high-voltage driving circuit,and a revisable high-voltage pulse sequence generation circuit used in color-PDP is realized.Different PDP display panels can share the same circuit system so as to reduce the cost and cycle of research.The experiment indicates that this circuit using synchronization circuit design can generate a stable and reliable driving waveform.[
