ST7565S
The Common Output Status Select Circuit
In the ST7565S chips, the COM output scan direction can be
selected by the common output status select command.
The LCD Driver Circuits
These are a 187-channel that generates four voltage levels
for driving the LCD . The combination of the display data, the
COM scan signal, and the FR signal produces the liquid
