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)
