以高性能的金属诱导单一方向横向晶化多晶硅薄膜晶体管(MIUCpoly-SiTFT)为基础,研制出性能能满足AM-LCD和AM-OLED要求、版图和象素尺寸适配、制备工艺和象素电路兼容的多晶硅TFT行扫描和列驱动电路.该行扫描电路工作电压为3.5-10V;当工作电压为5V、负载电容为22pf时,下降沿约为150ns,上升沿约为205ns,最高工作频率在1MHz以上;列驱动电路工作电压为3.5-8V;当工作电压为5V、负载电容为22pf时,上升沿约为200ns,信号衰减率为15%(64μs扫描周期),最高工作频率达到4MHz.将该MIUCpoly-SiTFT多晶硅行扫描、列驱动电路和有源选址电路集成到同一基板上,制备出象素数为80×RGB×60、动态显示效果良好的全集成型LCD屏样品.
Based on the high performance metal-induced single-direction lateral crystallization polycrystalline silicon thin film transistor (MIUCpoly-SiTFT), the performance is developed to meet the requirements of AM-LCD and AM-OLED, the layout and pixel size, the preparation process and the pixel circuit Compatible polysilicon TFT line scan and column driver circuit. The line scan circuit operating voltage 3.5-10V; when the operating voltage of 5V, the load capacitance of 22pf, the falling edge of about 150ns, the rising edge of about 205ns, the maximum operating frequency at 1MHz above; Column drive circuit operating voltage 3.5-8V; when the operating voltage of 5V, the load capacitance of 22pf, the rising edge of about 200ns, the signal attenuation rate of 15% (64μs scan cycle), the maximum operating frequency of 4MHz. The MIUCpoly-SiTFT polysilicon line scan, column driver circuit and active addressing circuit are integrated on the same substrate to prepare a fully integrated LCD screen sample with a pixel count of 80 × RGB × 60 and good dynamic display.
