產品敘述
WEO012832M-CTP型號是一款0.91吋COG繪圖型OLED顯示器，採用In-Cell內嵌式電容觸控面板，解析度為128x32像素。模組內建SSD7317 TDDI IC，此款IC採用TDDI IC為觸控與面板整合驅動IC (Touch with Display Driver)，將面板驅動IC和觸控面板IC整合成一顆晶片的觸控技術，WEO012832M-CTP 型號PMOLED模組採用內嵌式 (In-Cell ) 觸控技術，主要可應用於穿戴裝置、智能家電和智能醫療保健裝置等產品應用。
WEO012832M-CTP型號採用In-Cell 內嵌式觸控面板技術，支援4線SPI和I2C介面，並支援四個區域觸控和單一方向左右滑動。邏輯電源電壓(VDD)為1.65V~3.5V，typical值3.3V，50%顯示畫面耗電流4mA @8.5V VCC (typical 值)，驅動方式1/32。此模組工作溫度範圍為-40℃~+80℃；儲存溫度範圍為-40℃~+85℃。
WEO012832M-CTP 型號 OLED 模組具有 10,000:1 的高對比度，可呈現更鮮豔、更深的黑色以及更明亮的白色。 這樣可以提高影像品質、更清晰的細節並提高可讀性。
