描述平板显示系统中最优扫描结构所对应的自相似分形拓扑结构图,提出分形扫描核心模块架构,分析n位分形扫描的递推结构,研究扫描过程中的子空间码与位码序列的关键特征,推导出序列生成的通用逻辑算法。在此基础上,设计了适合各种灰度等级的参数化的分形IP核并得到仿真结果,同时给出了分形IP核的系统应用,证明所设计的IP核可以有效提高灰度扫描的利用率和FPD画面质量。

This paper describes the self-similar fractal topology derived from the optimal scan structure in flat panel display （FPD） scan, proposes the fractal scan architecture, analyzes the recursion structure for n-bit fractal scan, investigates the characteristics of sub-space code and bit code and deduces the general algorithm for the code sequences. Then a parameterized IP core for various gray levels is presented with simulation results and its real application. The IP core meets the expected design goal and can effectively increase scan utilization and FPD image quality.
