The WEH002002A is a COB-structured OLED display module featuring a 20x2 character configuration. It boasts a 3.08-inch diagonal module size with an active display area of 77.30 x 11.85 mm and integrates the WS0010-TX all-in-one font IC. Supporting the default interface of 6800, with optional 8080 or SPI interfaces, it operates in a 1/16 duty drive mode. All standard Winstar COB OLED character types are equipped with this all-in-one Fonts controller IC, offering support for ASCII, English, Russian, European, and Japanese character sets via a built-in ROM standard font library.
The WEH002002A shares identical outline dimensions (116.0 x 37.0 mm) and view area size (85.0 x 18.6 mm) as the Winstar LCD WH2002A, utilizing the same pinout configuration. This low-power 20x2 character OLED display is highly recommended for replacing existing STN character displays.
Key features of the OLED include:
The module has an integrated PCB board, eliminating the need for customers to develop additional PCBs. Additionally, four screw holes on the PCB board simplify installation for customers. Operating at a logic supply voltage ranging from 4.8V to 5.3V (typically 5.0V), this OLED module ensures reliable performance across a broad temperature spectrum, with storage capabilities from -40°C to +85°C. It also offers multiple emitting colors to cater to diverse customer preferences.
For applications requiring a character OLED display or a 20x2 OLED, the WEH002002A stands out for its efficient performance and versatile functionality.
