Figure 29.35. LCD 1/3 Bias and Quadruplex Multiplexing - LCD_COM2
Figure 29.36. LCD 1/3 Bias and Quadruplex Multiplexing - LCD_COM3
1/3 bias and quadruplex multiplexing - LCD_SEG0
The LCD_SEG0 waveform on the left is just an example to illustrate how different segment waveforms
can be multiplexed with the COM lines in order to turn on and off LCD pixels. As illustrated in the
figures below, this wave form will turn ON pixels connected to LCD_COM0 and LCD_COM2, while pixels
connected to LCD_COM1 and LCD_COM3 will be turned OFF.
