產品敘述
WF35RTIACDNNB是一款3.5吋彩色QVGA解析度320x240 dots的TFT LCD模組。此模組內建SSD2119 IC，因此無需額外的控制板即可支援MCU與SPI介面，帶來了價格優勢。它支援多種傳輸方式，包括6800 / 8080 MCU、SPI、RGB介面，供電電壓(VCI)範圍為2.5V至3.6V。該模組採用霧面防眩光玻璃，視角方向為12點鐘，灰階反轉方向為6點鐘，螢幕長寬比為4:3。
WF35RTIACDNNB型號的TFT模組採用橫屏模式，亮度為400 nits(典型值)。它可以在-20℃至+70℃的溫度範圍內運作，並且可以在-30℃至+80℃的溫度範圍內儲存。這使得它適用於各種工業控制產品應用顯示器。
