Bolymin OLED character displays with a high degree of compatibility with the original LCD modules are ideal not only for brand new projects, but they also serve as excellent upgrades for older projects.
The advantage is that all these character OLED displays have the same controller - HD44780 (with 4/8 bit 6800 MCU interface, simple 5V power supply) and thus any migration between individual types will be trouble-free.
You can find them in our stable stock offer in yellow and white colour, i.e. in the two most important and recommended colours in terms of long display lifetime (100k/70k hours) and good readability.
To preserve the longest possible lifetime and even “wear” of the pixels of the characters, it is very convenient if you can use (at least partially) scrolling text in your application.
As most industrial OLED displays on the market today, the BL-series modules can also operate within an extremely wide operating temperature range of -40 to +80°C. However, high long-term operating temperatures shorten the life of all OLED displays.
