An OLED display works without a backlight. Thus, it can display deep black levels and can be thinner and lighter than a liquid crystal display (LCD). In low ambient light conditions such as a dark room an OLED screen can achieve a higher contrast ratio than an LCD, whether the LCD uses cold cathode fluorescent lamps or LED backlight. Due to its low thermal conductivity, an OLED typically emits less light per area than an inorganic LED.

By default, this module is set up to be 4 or 8-bit HD44780 compatible. The controller allows you to use it as a 100x16 graphic display as well - check the WS0010 datasheet for details.

This OLED is not compatible with any of our LCD shields or backpacks!

• - 16 characters wide, 2 rows
• - Bright blue OLED text on black background
• - Connection port is 0.1" pitch, single row for easy breadboarding and wiring
• - Pins are documented on the back of the LCD to assist in wiring it up
• - No backlight! Each pixel is an individual LED
• - Can be fully controlled with only 7 digital lines! (Any analog/digital pins can be used)
• - Built in default character set supports English/Japanese text. Can also be set to use Western European and Russian, see the WS0010 datasheet for the full character sets
• - Up to 8 extra characters can be created for custom glyphs or 'foreign' language support
