Abstract
The present disclosure discloses a source driver chip comprising a reference voltage input terminal and a data signal output channel in which an operational amplifier for outputting a data signal is disposed. When at least one of the operational amplifiers is in idle instead of being used for outputting the data signal, the operational amplifier in idle is connected to the reference voltage input terminal and used to amplify a reference voltage inputted to the reference voltage input terminal; or the operational amplifier in idle is connected to an external circuit and used to amplify an external circuit signal other than the reference voltage. The present disclosure can save the operational amplifiers in the peripheral driving circuit, and reduce the cost of the peripheral driving circuit as well as the power consumption.
