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:

• Faster response time at +25°C (10 microseconds)
• Unlimited viewing angle up to 175 degrees
• Thin design with self-emitting technology, eliminating the need for a backlight
• High brightness and a contrast ratio of up to 10,000:1
• Wide operating temperature range from -40°C to 80°C
• Lower power consumption, contributing to reduced CO2 emissions

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.
