1. An apparatus, comprising:
- a display component comprising pixel-drive electrodes configured to display an image;
a touch sensor component configured to detect a touch input;
a touch-screen controller coupled to the touch sensor component, the display component, and the pixel-drive electrodes, the touch-screen controller configured to;
generate a drive signal for the touch sensor component using a first subset of the pixel-drive electrodes; and
generate a pixel-drive signal for the display component using a second subset of the pixel-drive electrodes, wherein the first subset is different than the second subset;
wherein the touch-screen controller is separately connected to each of the pixel-drive electrodes such that the touch-screen controller treats the pixel-drive electrodes as separate entities when generating the pixel-drive signal to display the image and collectively when generating the drive signal to detect the touch input.

Abstract
In one embodiment, an apparatus includes a display component, a touch sensor component, and a touch-screen controller. The display component includes pixel-drive electrodes configured to display an image and the touch sensor component is configured to detect a touch input. The touch-screen controller, which is coupled to the touch sensor component, the display component, and the pixel-drive electrodes, is configured to generate a drive signal for the touch sensor component using the pixel-drive electrodes. The touch-screen controller is further configured to generate a pixel-drive signal for the display component using the pixel-drive electrodes.
