BU91501KV-M
LCD Driver Bias/Duty Circuit
This LSI generates LCD driving voltage with on-chip Buffer AMP.
And it can drive LCD at low power consumption.
* 1/3 or 1/2Bias and line or frame inversion mode can be selected by DRV CTRL2.
* 1/4 or 1/3Duty can be selected by DRV CTRL1 command.
Refer to “LCD waveform” about each LCD waveform.
