【摘要】 本论文的具体工作是结合韩国PT-PLUS 公司的LDD 型P-Si TFT 的制备工艺,根据相关的设计规则、工艺文件及0LED 的工作条件,完成了64×3×80 显示发光区与驱动电路集成一体化的P-Si TFT 阵列的模拟、计算、和布图设计,显示区的面积是2.1 英寸,外接引线仅有36条,如果同样的a-Si TFT 阵列就需要275 条之多。这在大尺寸显示屏中是极具优越性的。设计过程中我们采用每个单元像素含有2 个TFT 的源跟随型电路,分析、计算了单元像素中丌关管和驱动管的宽长比,存储电容的数值和面积。完成了Poly-Si TFT AM OLED 的所有基本单元分析、计算并进行仿真,验证,最终完成了布图设计,并对版图进行了DRC,LVS 及ERC校验。由于软件条件的限制,只将版图进行了包含寄生参数的网表提取,没有进行整体电路的后仿真,同时对于布线可能引起的时钟分配问题,电压降问题,热效应问题也由于条件的限制没有完成。最后的显示屏能够发光,表明我们的设计是正确可行的。但是由于大面积多晶硅均匀性解决得不好,导致显示区发光不均匀,甚至有些像素出现坏点。更多还原

【Abstract】 In the information society, people would beface various manifestation facilitie. OLED is one of the newflat panel displays, have already got the private’s deep concernthat science field and the industry fields know.The drive ways of OLED can be divided into thePassive Matrix and the Active Matrix.The manufacture crafttechnique of PMOLED is more easy, The biggest advantage thatPM-OLED is a price, but together it compare in the sacrifice onthe function, the opposite and" cheap" price can’t make it evendraw on the person.In AM-OLED each pixel has two or more TFTs, use todrive the OLED, in order to in the whole period the OLED canwork. Apply in the AMOLED of TFT mainly is divided into theP-Si TFT and the a-Si TFT. The a-Si TFT has the craftof manufacture simple. Along with the development of theTFT-OLED, the weakness of the a-Si TFT becomes sharpgradually, polysilicon have more advantages.The research focus on the design of polysilicon TFTOLED array has been studied with the design rule and themanufacture crafts that combines our laboratory existing OLEDmanufacture technique and the equipments levels. A new simpleand precise procedure is presented to design polysilicon TFT更多还原
