Abstract: A sensor substrate includes a base substrate, a black matrix pattern, a sensing electrode pattern, a driving electrode pattern, and at least one bridge line. The black matrix pattern is disposed on the base substrate and divides the base substrate into a light transmission area and a light blocking area. The sensing electrode pattern includes a plurality of first unit patterns arranged in association with a first direction. The driving electrode pattern includes a plurality of second unit patterns arranged in association with a second direction and disposed adjacent to the plurality of first unit patterns. The at least one bridge line is connected between at least two of the plurality of first unit patterns or between at least two of the plurality of second unit patterns.

Abstract: A display apparatus including a display panel, a touch panel, a data driver, a common voltage noise predictor and a touch position detector. The display panel includes a plurality of data lines and a plurality of pixels. The pixels are electrically connected to the data lines, respectively. The touch panel is configured to output a first touch signal based on a touch event. The data driver is configured to output a data voltage to the data line based on a data signal. The common voltage noise predictor is configured to output a common voltage noise compensating signal based on the data signal. The touch position detector is configured to detect a touch position based on the common voltage noise compensating signal and the first touch signal.
