在驱动大尺寸STN-LCD屏时,多行寻址(MLA) LCD驱动方式具有比IAPT驱动方式更优良的对比度和抗串扰能力,功耗更低.基于正交矩阵算法,在分析驱动电路原理的基础上设计了一种8行寻址(MLA-8) LCD驱动电路.基于Maxchip 0.18 μm 18 V CMOS工艺实现了流片.测试结果表明,该8行寻址LCD驱动电路比传统IAPT驱动电路的功耗降低了70％.“,”Multi-line addressing (MLA) LCD driving technology has better characteristics of contrast,anti crosstalk and lower power consumption than IAPT driving technology when driving large size STN-LCD screen.An eight line addressing (MLA-8) LCD driver base on orthogonal matrix had been designed after analyzing the principle of driving circuits.It had been taped out in Maxchip 0.18μm 18 V CMOS process.The tested results showed that the power consumption of the proposed MLA-8 LCD driver was reduced by 70 ％ than that of the traditional IAPT driver.
