There are disclosed display devices with integral touch screens and methods for operating display panels. A display panel may include a plurality of pixels, each pixel controlled by a corresponding one of a plurality of column electrodes and a corresponding one of a plurality of row electrodes. Each column electrode may be coupled to a respective column driver circuit and at least some of the column electrodes may be coupled to respective column sensing circuits adapted to sense capacitive coupling between the respective column electrodes and a probe adjacent to an external surface of the display panel. Each row electrode may be coupled to a respective row driver circuit and at least some of the row electrodes may be coupled to respective row sensing circuits adapted to sense capacitive coupling between the respective row electrodes and a probe adjacent to an external surface of the display panel.
