Figure 29.3. LCD Normal Waveform for LCD_COM0 in Quadruples Multiplex Mode, 1/3 Bias
The numbers on the illustration's y-axes in the following sections only indicate different voltage levels.
All examples are shown with low-power waveforms.
• With static bias and multiplexing, each segment line can be connected to LCD_COM0. When the

Figure 29.4. LCD Static Bias and Multiplexing - LCD_COM0
In this mode, each frame is divided into 4 periods. LCD_COM[1:0] lines can be multiplexed with all
segment lines. Figures show 1/2 bias and duplex multiplexing (waveforms show two frames)
Figure 29.5. LCD 1/2 Bias and Duplex Multiplexing - LCD_COM0
segment line has the same waveform as LCD_COM0, the LCD panel pixel is turned off, while when
the segment line has the opposite waveform, the LCD panel pixel is turned on.
