Abstract
A data driver, a multi-channel sensing circuit, and a sensing method thereof are provided. A multi-channel sensing circuit and a sensing method thereof are provided, in which a configuration of a sample / hold circuit section is simplified to reduce a circuit area. The multi-channel sensing circuit can include a first sample / hold circuit that samples and outputs a first sensing voltage, a second sample / hold circuit that samples and outputs a second sensing voltage, a shared sample / hold circuit that samples and outputs a reference voltage, and an amplification section that differentially amplifies the first sensing voltage output from the first sample / hold circuit and the reference voltage output from the shared sample / hold circuit, and differentially amplifies the second sensing voltage output from the second sample / hold circuit and the reference voltage output from the shared sample / hold circuit.
