Abstract: A display apparatus and a method for noise reduction are introduced. The method comprises steps of sensing a first pixel signal being superimposed by noises from a first pixel through a first sensing line in a first phase of a sensing operation and sensing a first noise signal from the first sensing line in a second phase of the sensing operation. The method further comprises steps of sensing a second noise signal from a second sensing line in the first phase of the sensing operation, and sensing a third noise signal from the second sensing line in the second phase of the sensing operation. The method further removes the noises that are superimposed to the first pixel signal according to a difference between the first pixel signal and the first noise signal and a difference between the second noise signal and the third noise signal to generate a denoised sensing value of the first pixel.
