Abstract: A display and a touch display are provided. The display includes a display panel and a source driver. The display panel includes pixels and a common electrode receiving a common voltage. The source driver is configured to provide current pixel voltages to the pixels and determine whether to insert at least one intermediate voltage level between each of the current pixel voltages and the corresponding previous pixel voltage based on the each of the current pixel voltages and the corresponding previous pixel voltage.

Abstract: A system for optimizing touch tracks includes a touch panel, a register, and a processor. The processor is used for receiving a plurality of touch signals of the touch panel, calculating a plurality of raw report points of the touch panel according to the plurality of touch signals, storing the plurality of raw report points in the register, utilizing a linear optimization method to generate an optimization curve corresponding to each raw report point of the plurality of raw report points according to previous i raw report points and following j raw report points of the plurality of raw report points corresponding to the raw report point, and generating an optimization report point corresponding to the raw report point according to the raw report point and the optimization curve, where i and j are positive integers.

Abstract: A capacitive touch panel is provided. The capacitive touch panel comprises a substrate, a plurality columns of first directional sensing electrodes, a plurality rows of second directional sensing electrodes and an optical compensation structure. Each two neighboring first directional sensing electrodes in each of the columns are connected with a connecting structure in series. The first and the second directional sensing electrodes are arranged in a staggered manner. Each two neighboring second directional sensing electrodes in each of the rows are connected with a bridging structure in series without contacting the connecting structure.
