Abstract:

Combined display panel circuit techniques are described herein. In one or more implementations, a combined panel circuit of a display device is configured to enable functionality for both recognition of touch inputs and functionality to update images output by the display device. The combined panel circuit, for instance, may include an electrode arrangement in conductive layers that sandwiches display particles used to form images for the display device. The display particles may be manipulated under the influence of a threshold voltage applied to the electrode arrangement that is sufficient to cause the display particles to transition between states. Capacitance sensing indicative of touch inputs may occur under the influence of a different voltage that is not sufficient to manipulate the display particles. The different voltages are selectively applied at different times to update displayed images through manipulation of the display particles and sense capacitance to recognize touch inputs.
