29.3.3.4 Waveforms with 1/2 Bias and Triplex Multiplexing
2010-12-21 - d0034_Rev0.90
Figure 29.16. LCD 1/3 Bias and Duplex Multiplexing - LCD_SEG0-LCD_COM1
In this mode, each frame is divided into 6 periods. LCD_COM[2:0] lines can be multiplexed with all
segment lines. Figures show 1/2 bias and triplex multiplexing (waveforms show two frames).
Figure 29.17. LCD 1/2 Bias and Triplex Multiplexing - LCD_COM0
Figure 29.18. LCD 1/2 Bias and Triplex Multiplexing - LCD_COM1
Figure 29.19. LCD 1/2 Bias and Triplex Multiplexing - LCD_COM2
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.
