Abstract
An embodiment of the present application discloses a display module and terminal apparatus. The display module includes a plurality of data driver integrated circuits. Each data driver integrated circuit includes a buffer amplifier, a gamma voltage terminal, a data voltage terminal, and a simulation voltage terminal. The buffer amplifier includes an input terminal electrically connected to the gamma voltage terminal, an output terminal electrically connected to the data voltage terminal, and an auxiliary signal input terminal electrically connected to the simulation voltage terminal. The simulation voltage terminal is electrically connected to the gamma voltage terminal via a capacitor. When switching between grayscales, a fluctuation of the simulation voltage terminal is coupled to a signal of the gamma voltage terminal by capacitive coupling, the signal of the gamma voltage terminal includes a fluctuation with the same phase as in the common voltage terminal.
