1/2 bias and triplex 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 waveform will turn ON pixels connected to LCD_COM1, while pixels connected to
LCD_COM0 and LCD_COM2 will be turned OFF.

• DC voltage = 0 (over one frame)
• V
• The LCD display pixel that is connected to LCD_SEG0 and LCD_COM0 will be OFF with this waveform
