摘要
分析了多晶硅薄膜晶体管(poly-Si TFT)有源矩阵驱动的结构和源驱动器的驱动原理及基本构成,并针对分辨率为800×600的64级灰度的VGA显示屏,采用分块矩阵的方法使数据转换频率降低到原来的1/10,在此基础上对传统的源驱动电路进行了改进,使DAC电路的数目大大减少,从而减小芯片面积,降低整个芯片的功耗。对电路采用Cadence进行仿真,给出了逻辑部分工作时序波形。
The structure of poly - Si TFT with active the source driver and its basic structure are also discussed matrix driving is analyzed. The driving principle of On the basis of a TFT LCD panel with an 800 × 600 resolution, a method of matrix compartmentation is adopted to reduce the data transform frequency to 1/10 what it was. The traditional source driver is improved so that the number of DAC circuit is greatly reduced, the size of this chip is reduced and the power consumption is cut down. This circuit is simulated with Cadenc. The scheduling is presented finally.
