发明名称 PRE-EMPHASIS CIRCUIT
摘要 A pre-emphasis circuit applied to a LCD panel is disclosed. The pre-emphasis circuit includes a digital-to-analog converting unit and a pre-emphasis control unit. The digital-to-analog converting unit includes a pre-emphasis switch. The digital-to-analog converting unit receives a data signal and a power reference level signal respectively and outputs an output signal. The pre-emphasis control unit is coupled to the digital-to-analog converting unit and used to selectively switch on or off the pre-emphasis switch to start or stop a pre-emphasis function performed on the output signal according to whether a grey-level code of the data signal is changed.
