Abstract
Provided are a driver chip and a display apparatus. The driver chip includes a digital module, an analog module, and a decoupling capacitor. The digital module is configured to generate a digital signal. The analog module includes a reference voltage source and a Gamma voltage generation circuit, an output terminal of the reference voltage source is electrically connected to an input terminal of the Gamma voltage generation circuit, and the Gamma voltage generation circuit is configured to generate a Gamma voltage according to a reference voltage outputted by the reference voltage source. The decoupling capacitor is connected between the digital module and the output terminal of the reference voltage source.
