Abstract:
A slew rate boosting circuit, a source driver chip and a display device are provided in the present disclosure. The slew rate boosting circuit comprises: a first latch configured to receive and store first data; a second latch configured to receive and store second data, the second data being next to the first data; a first level shifter; an amplifier; and a slew rate boosting module configured to receive a high voltage data signal as current input data, and adjust a slew rate of an output stage of the amplifier according to a value of a specified bit of the first data, a value of a specified bit of the second data and the current input data.
