WEX025664B-CTP ist ein 3,12-Zoll großes grafisches OLED-Displaymodul in COF-Bauweise mit integriertem kapazitivem Touchpanel (CTP) und einer Auflösung von 256×64 Pixeln. Das Modul basiert auf dem SSD1322-Treiber-IC und unterstützt 6800/8080 8-Bit Parallel-Schnittstellen sowie 3-/4-Draht SPI. Die Modulabmessungen betragen 89,2 × 29,0 mm, die aktive Anzeigefläche 76,778 × 19,178 mm.
Das OLED-Modul unterstützt 4-Bit Graustufendarstellung und arbeitet mit einer Versorgungsspannung von 3,0 V (typ.) sowie einem 1/64 Duty-Ansteuerverfahren. Der Betriebstemperaturbereich liegt bei -20°C bis +70°C, der Lagertemperaturbereich bei -30°C bis +80°C. Das integrierte Touchpanel verwendet den FT6336U-Controller und unterstützt eine I²C-Schnittstelle sowie Einpunkt-Touch.
WEX025664B-CTP eignet sich für Anwendungen wie Wandgeräte, POS-Systeme, IoT-Geräte, tragbare Messinstrumente, Kommunikationssysteme und medizinische Geräte. Ebenso ist das Modul für Anwendungen geeignet, die von herkömmlichen STN-Displays auf OLED-Technologie umgestellt werden.
