The WEH000802A is an 8x2 OLED display module with an outline size of 58.0 × 32.0 mm and a viewing area (VA size) of 38.0 × 16.0 mm, sharing the same pinout as the Winstar STN LCD item no. WH0802A. It features OLED technology with 8 characters x 2 lines and a diagonal size of 1.2 inches.
This 8x2 OLED display module operates with a supply voltage for logic ranging from 4.8V to 5.3V, with typical values at 5.0V. The WEG005016A is the equivalent graphic module of the WEH000802A, offering a display format of 50 x 16 dots for applications requiring graphic mode.
Both the WEH000802A and WEG005016A 1.2" OLED display models can serve as compatible replacements for LCD or VFD modules. They support the 6800 interface by default, with additional options available including 8080 and SPI. All Winstar standard OLED character types are equipped with an all-in-one Fonts controller IC, providing 4 font sets in one device. The built-in ROM standard font library includes ASCII, English, Russian, European, and Japanese character sets.
The WEH000802A OLED series with a PCB board can easily connect to the application using wires. Customers do not need to develop additional PCB boards themselves. Four screw holes are designed on the PCB to facilitate easier installation of the module onto the application product.
This 8x2 OLED module is designed to operate in temperatures ranging from -40℃ to +80℃, with storage temperatures from -40℃ to +85℃. Featuring a high contrast ratio of 10,000:1, the OLED module delivers vibrant and true-to-life colors, deep blacks, and bright whites.
