Character OLEDs are monochrome passive matrix displays with built-in font tables and screen savers. Each character OLED is self-illuminating and can achieve a higher level of contrast when compared to LCDs because of their ability to obtain richer black levels without backlight interference.

Slim OLEDs These displays are packaged as complete modules including all required logic, while containing a slim, 5mm profile. Character size formats include 2 x lines by 16 characters, 2 x lines by 20 characters and 4 x lines by 20 characters with the flexibility of using them as double height characters. These slim character OLEDs have a superior contrast ratio of 10,000:1 for outstanding clarity and can achieve faster, smoother graphic animations with their 10μsec response time.
