产品叙述
WEO012832M-CTP型号是一款0.91吋COG绘图型OLED显示器，采用In-Cell内嵌式电容触控面板，分辨率为128x32像素。模块内建SSD7317 TDDI IC，此款IC采用TDDI IC为触控与面板整合驱动IC (Touch with Display Driver)，将面板驱动IC和触控面板IC整合成一颗芯片的触控技术，WEO012832M-CTP 型号PMOLED模块采用内嵌式 (In-Cell ) 触控技术，主要可应用于穿戴装置、智能家电和智能医疗保健装置等产品应用。
WEO012832M-CTP型号采用In-Cell 内嵌式触控面板技术，支持4线SPI和I2C接口，并支持四个区域触控和单一方向左右滑动。逻辑电源电压(VDD)为1.65V~3.5V，typical值3.3V，50%显示画面耗电流4mA @8.5V VCC (typical 值)，驱动方式1/32。此模块工作温度范围为-40℃~+80℃；储存温度范围为-40℃~+85℃。
WEO012832M-CTP 型号 OLED 模块具有 10,000:1 的高对比度度，可呈现更鲜艳、更深的黑色以及更明亮的白色。 这样可以提高影像质量、更清晰的细节并提高可读性。
