Figure 29.9. LCD 1/2 Bias and Duplex Multiplexing - LCD_SEG0-LCD_COM0
1/2 bias and duplex multiplexing - LCD_SEG0-LCD_COM1
• 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
Figure 29.10. LCD 1/2 Bias and Duplex Multiplexing - LCD_SEG0-LCD_COM1
In this mode, each frame is divided into 4 periods. LCD_COM[1:0] lines can be multiplexed with all
segment lines. Figures show 1/3 bias and duplex multiplexing (waveforms show two frames).
