The WEH002004A is a COB-structured OLED display module featuring a 20x4 character configuration. It boasts a 2.88-inch diagonal module size with an active display area of 70.16 x 20.95 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 WEH002004A shares identical outline dimensions (98.0 x 60.0 mm) and view area size (77.0 x 25.2 mm) as the Winstar LCD WH2004A, utilizing the same pinout configuration. Winstar's 20x4 OLED Display is an excellent choice for upgrading applications from STN LCDs to OLED displays. Key features 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. 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 20x4 OLED display, the WEH002004A stands out for its efficient performance and versatile functionality.
