Description
WEH001202A is a standard character display module with a 12 characters x 2 lines display format, COB structure, and a diagonal size of 1.6 inches. The 12x2 OLED display WEH001202A shares the same outline size of 55.7 x 32.0 mm, viewing area (VA size) of 46.0 x 14.5 mm, and pinout as the Winstar STN LCD item no. WH1202A.
The WEG007616A serves as the equivalent graphic module to WEH001202A, featuring a display format of 76x16 dots for applications requiring graphic mode. Both the WEH001202A and WEG007616A models can function as compatible replacements for LCD or VFD modules.
They offer various optional interfaces, with the default being 6800, and additional options 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 a single device. The built-in ROM standard font library includes ASCII, English, Russian, European, and Japanese character sets.
The WEH001202A OLED series with a PCB board can easily connect with 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 12x2 OLED display module operates with a supply voltage for logic ranging from 4.3V to 5.8V, with typical values at 5.0V, and features a high contrast ratio of 10,000:1. It can operate in temperatures ranging from -40℃ to +80℃, with storage temperatures from -40℃ to +85℃.
