29.3.3.5 Waveforms with 1/3 Bias and Triplex Multiplexing
2010-09-06 - d0001_Rev1.00
1/2 bias and triplex multiplexing - LCD_SEG0-LCD_COM1
• DC voltage = 0 (over one frame)
• V
• The LCD display pixel that is connected to LCD_SEG0 and LCD_COM1 will be ON with this waveform
Figure 29.23. LCD 1/2 Bias and Triplex Multiplexing - LCD_SEG0-LCD_COM1
1/2 bias and triplex multiplexing - LCD_SEG0-LCD_COM2
• DC voltage = 0 (over one frame)
• V
• The LCD display pixel that is connected to LCD_SEG0 and LCD_COM2 will be OFF with this waveform
Figure 29.24. LCD 1/2 Bias and Triplex Multiplexing - LCD_SEG0-LCD_COM2
In this mode, each frame is divided into 6 periods. LCD_COM[2:0] lines can be multiplexed with all
segment lines. Figures show 1/3 bias and triplex multiplexing (waveforms show two frames).
