Standard HD44780 LCD 20x4 characters and with Connection port is 0.1" pitch, single row, 20 characters wide, and has four rows for convenient breadboarding and wiring. You can power a single LED backlight with a resistor by applying 5V directly. It can be readily dimmed with a resistor or PWM if it is too bright for you, and it consumes a lot less power than LCDs with EL (electroluminescent) backlights. it can be fully controlled with only 6 digital lines, and the built-in character set supports English/Japanese text, see the HD44780 datasheet for the full character set Up to 8 extra characters can be created for custom glyphs or 'foreign' language support (like unique accents)
