产品叙述
WF70A7TIAHLNB0是一款分辨率1024x600像素的7寸TFT显示器，模块上带有含USB接口的PCAP电容式触控面板。此款TFT模块支持LVDS接口，电容式触控面板内置ILI2511 驱动IC，PCAP面板支持USB接口，同步可支持I2C接口，因两者为同一韧体，链接模块后驱动IC会自行判断输入的讯号是I2C或是USB讯号。此款的Cover Lens因应欧美市场需求, Lens的外观尺寸比TFT模块大。
此款产品的模块亮度是450 nits，供电电压(DVDD)范围从3V~3.6V。TFT模块的面板是亮面玻璃，视角12点钟方向，灰阶反转6点钟方向，屏幕长宽比16:9，灰阶反转12点钟方向。此款模块的工作温度是-20℃ 至 +70℃，储存温度是 -30℃ 至 +80℃。
