Electronic device of a source driver in an LCD device for enhancing output voltage accuracy
An electronic device of a source driver in an LCD device, for enhancing accuracy of voltage outputted to an equivalent capacitor of a panel of the LCD device, includes a first node, a second node, an output unit, a first charge sharing switch, a second charge sharing switch, a first precharge switch, and a second precharge switch. The electronic device only uses two precharge switches to implement the precharge function and can decrease the current limiting resistor for enhancing the output voltage accuracy and decrease the charge time of the equivalent capacitor.
