Abstract
The present disclosure provides a pre-emphasis circuit, method and display device, and belongs to a field of display driving. The pre-emphasis circuit according to the disclosure can determine whether to output a pre-emphasis voltage corresponding to grayscale of current input data via an input terminal of an amplifier according to data input to a data terminal by adding an amplifier input pre-emphasis module. Rapid conversion of output voltage can be realized without increasing the quiescent current of the amplifier, while the stability of temperature of the IC is ensured.
