WO240128B單色COG LCD液晶顯示器是一款240x128點陣式4.8吋的繪圖型模組。WO240128B內建ST7586S 控制器IC, 支援多種傳輸介面: 6800 8-bit, 8080 8-bit 平行介面與3-線9-bit /4-線8-bit 串列SPI介面。WO240128B為COG結構模組,其VA區尺寸以及AA區尺寸與現有華凌標準品COB結構的WG240128B相同,但WO240128B為COG結構,所以模組厚度較薄,外形輕巧,具有低功耗,低供電等特點,客戶若有需求4.8吋模組的新案開發,建議可採用此WO240128B模組。
WO240128B的工作溫度是-20℃至+70℃,儲存溫度-30℃至+80℃,此型號目前有STN Negative 負顯, 與 FSTN positive正顯兩種玻璃可供選擇,可搭配LED白光,如有需求其他LCD或是LED背光組合可與我們聯繫。
