The ST7920 incorporates cost-cutting measures like an in-built diode charge pump to generate the LCD voltage instead of relying on external 7660 charge pumps like KS0108B-based displays do, which helps to keep module costs down. This allows it to be used as a near drop-in replacement for traditional 5x8 HD44780-compatible displays with minimal code changes, and it even works with the AXE133 PCB. Just another graphic display controller like the crude KS0108B No This advanced display controller brings high-resolution (8x16 and 16x16) in-built character ROMs and a comprehensive instruction set compatible with the HD44780 command set. The ST7920 has actually been around for the best part of two decades, but it doesnt seem to get much attention. Fortunately, the Chinese came up with the solution: the Sitronix ST7920.
