摘　　要：根据TFT-LCD的驱动原理,研究了一种基于客户定制化设计的非规则液晶显示屏,提出了此种液晶显示屏驱动芯片布局及其同液晶屏幕的连接方式。分析了此种非规则设计的液晶显示屏时序控制的独特之处,并利用FPGA设计了其时序控制器。根据乒乓操作的原理,利用FPGA进行了数据的缓存及分流等处理。为降低电磁干扰,提高产品性能,设计了基于FPGA的RSDS接口。文章还展示了此非规则设计液晶显示屏的静态及动态显示效果。Based on the driving principles of thin film transistor liquid crystal display （TFT-LCD）, an irregular LCD based on customized design was researched, the alignments of driving chips and the connection between the screen and chips were presented. The specialty of timing control was illustrated, and the timing controller of this irregular LCD was designed through FPGA. Based on the principle of Ping-Pong operation, internal data buffer and shunt in FPGA were implemented. In order to reduce EMI, improve the performance of the product, Reduced Swing Differential Signaling interface was designed based on FPGA. The display quality of static and dynamic pictures that displayed in this irregular designed LCD was showed in the paper.
