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.

14. A method implemented by a controller of a display device comprising:
-
causing formation of an image for display via the display device by supplying a first voltage to a combined panel circuit of the display device, the first voltage sufficient to manipulate display particles of the display device to form the image; and measuring via the combined panel circuit capacitance associated with touch input at positions of the display device by selectively applying a second voltage to the combined panel circuit, the second voltage insufficient to manipulate the display particles. - View Dependent Claims (15, 16, 17)

18. A computing device comprising an integrated display device including:
-
a combined panel circuit configured to implement both a sensing mode to measure capacitance at positions of the display device and a display driving mode to rearrange display particles corresponding to the positions to control images displayed via the display device; and a controller to selectively switch between the sensing mode and the display driving mode by applying different respective voltages to the combined panel circuit at different times. - View Dependent Claims (19, 20)
