Methods and devices are described for operating an input device for an electronic system which includes a housing. The input device includes an input surface and a first substrate having a first plurality of sensor electrodes configured to sense input objects proximate the input surface, and a pair of force sensing electrodes on the bottom of the first substrate. The input device includes a second substrate having a planar spring plate including a perimeter region surrounding an interior region, the perimeter region including a leaf spring coupled to the housing, and a spacing layer configured to physically couple the interior region of the second substrate to the first substrate. A force applied to the input surface deflects the first substrate and the interior region relative to the perimeter region, changing a variable capacitance formed between the force sensing electrodes.

Techniques for displaying a quality-improved image with reduced power consumption are provided. In one embodiment, a display panel driver is provided that includes a dithering section configured to receive first m-bit image data and configured to generate second image data by performing dithering on the first image data with n-bit dither values each selected from elements of a dither table, and a driver circuit configured to drive the source lines of a display panel in response to the second image data. In generating the second image data corresponding to first pixels belonging to a first pixel column, the dither values are selected from elements in a first column of the dither table, while the second image data corresponding to second pixels belonging to a second pixel column adjacent to the first pixel column, the dither values are selected from elements in a second column of the dither table.

Devices and method are provided that facilitate improved input device performance. Specifically, the systems and methods are configured to identify a portion of an image of sensor values as corresponding to at least one sensed object in the sensing region, determine a polygon corresponding to the identified portion of the image, and determine a contact characterization of the at least one sensed object based on the polygon. The determination of a polygon corresponding to a sensed object facilitates improved contact characterization of the sensed object. For example, the determined polygon may be used to determine if the sensed object is actually more than one object. As a second example, the determined polygon may be used to determine the orientation of the sensed object. In addition, determined polygons may be used to more accurately track changes in the position of the sensed object.
