The WEH002004B series is a 2.88-inch character OLED display featuring a 20x4 character configuration. It integrates the WS0010-TX IC and supports the default 6800 interface, with optional 8080 or SPI interfaces, operating in a 1/16 duty drive mode. All standard Winstar COB OLED character types are equipped with this all-in-one Fonts controller IC, providing support for ASCII, English, Russian, European, and Japanese character sets through a built-in ROM standard font library.
Winstar's OLED 20x4 display, WEH002004B, shares identical outline dimensions (98.0 x 60.0 mm), viewable area size (77.0 x 25.2 mm), and pin configuration with the Winstar STN LCD standard model WH2004B. Upgrading applications from STN LCDs to OLED displays, Winstar's OLED 20x4 proves to be the optimal choice.
For applications requiring graphical content display, the WEG010032B serves as the graphical counterpart to the WEH002004B, offering a resolution of 100 x 32 pixels.
The WEH002004B series OLED 20x4 module includes an integrated PCB board, eliminating the need for customers to develop additional PCBs. Installation is simplified with four screw holes on the PCB board. Operating at a logic supply voltage ranging from 4.8V to 5.3V (typically 5.0V), it functions reliably across temperatures from -40°C to +80°C, with storage capabilities from -40°C to +85°C. It also offers multiple emitting colors to cater to diverse customer preferences.
