I have a multiplex LCD (datasheet attached) that I want to use with the PIC16F913 from Microchip.
I understand that multiplexing uses multiple commons, but how do I know how many bias voltage levels to use? I attached a section of the datasheet dealing with the LCD driver. They have a typeA and typeB waveform, but that just deals with the phase. They also have a 1/3 mux, 1/2 bias and a 1/3 mux, 1/3 bias to choose from.
The LCD datasheet has nothing about bias voltages - how do I choose which combination to use? Can I use either? Thanks!
