The Winstar WEH004002A is a 5.85-inch OLED module characterized by a COB structure, with the same outline size, VA size, and pinout as the Winstar STN LCD standard item WH4002A. This OLED 40x2 display features the WS0010-TX IC, which supports various interface options including 6800 (default), 8080, and SPI. Key features of the OLED display include a brighter and higher contrast display, wider viewing angles, faster response times, self-illumination, and lower current consumption.
For applications requiring graphic mode display, the equivalent model is the Winstar WEG020016A.
All Winstar standard COB OLED character types come with an integrated Fonts controller IC, WS0010-TX. The built-in ROM standard font library includes ASCII, English, Russian, European, and Japanese character sets.
Operating at a logic supply voltage of 4.8V to 5.3V (typically 5.0V), this OLED module operates across a wide temperature range from -40°C to +80°C, with storage temperatures from -40°C to +85°C. It boasts a high contrast ratio of 10,000:1 and offers multiple emitting colors for customer selection.
