产品叙述
WF39QTIBSDBG0是3.9寸 Bar TFT的衍生性产品，此款产品属于华凌TFT Q系列的产品含SSD1963控制板，具Winstar Q系列的产品特色，在SSD1963控制板上包含一个整合性统一脚位出pin的36-pin的connector 连接器在模块上。WF39QTIBSDBG0型号面板分辨率480x128像素，此款TFT含电容式触控面板(PCAP)，模块支持8080 MPU 8bit/16bit 接口(MCU interface)。 触控面板的IC使用CYTMA568或是兼容IC， 与其他Winstar Q系列产品相同，第33到36 pin脚位都预设定义为背光电源输入。
WF39QTIBSDBG0含PCAP触控面板，亮度为400 nits，对比度500:1。此款模块因为含PCB板，模块外观尺寸与单色STN的WH1602L1相仿都是122.0 x 44.0 mm (PCB outline)，所以WF39Q含控制板的产品是单色STN升级为彩色TFT的最佳选择。
