METHOD AND APPARATUS TO SUPPORT VARIOUS SPEEDS OF LCD DRIVER |
摘要 |
Charge pump circuitry comprises a voltage for generating a first regulated voltage. A low drop out regulator generates a second regulated voltage responsive to the first regulated voltage. A charge pump voltage generation circuit generates a voltage. First and second resistor strings are responsive to the generated voltage. The first resistor string provides a first plurality of bias voltages to an LCD responsive to the voltage in a first mode of operation and the second resistor string provides faster charging and discharging of the connected LCD elements responsive to a second mode of operation.
