| 摘 要： | 传统的多路寻址液晶驱动矩阵电路设计规模与矩阵阶数平方成正比。研究表明:由正交块循环矩阵构造出的多路寻址驱动矩阵的实现复杂度由原来的与矩阵的阶数平方成正比下降为与矩阵的阶数成正比。分析正交块循环矩阵特性后,介绍了基于类单位矩阵的系统化构造正交块循环矩阵的方法。在多行(COMMON)快速帧频响应的多路寻址液晶驱动设计中采用正交块循环矩阵可大大降低实现成本。

| Abstract: | The design scale of traditional driving matrix of MLA-LCD is in proportion to square of matrix dimension.It is indicated by the research that making up driving matrix of MLA-LCD by Orthogonal Block Circulant Matrix can make the design scale down from square of matrix dimension to matrix dimension.The new method of making up Orthogonal Block Circulant Matrix systematically by Paraunitary Matrix is also presented.This new application with Orthogonal Block Circulant Matrix will bring great scale cost down range in MLA-LCD design in the condition of high COMMON count and fast frame. |
