Figure 29.6. LCD 1/2 Bias and Duplex Multiplexing - LCD_COM1
1/2 bias and duplex 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 LCD_COM lines in order to turn on and off LCD pixels. As illustrated in the
figures below, this waveform will turn ON pixels connected to LCD_COM0, while pixels connected to
LCD_COM1 will be turned OFF.

1/2 bias and duplex multiplexing - LCD_SEG0-LCD_COM0
• DC voltage = 0 (over one frame)
• V
• The LCD display pixel that is connected to LCD_SEG0 and LCD_COM0 will be ON with this waveform.
