Liquid crystal display integrated with touch sensor

摘要

A liquid crystal display with a touch sensor includes a first substrate having a plurality of pixels coupled to gate lines and data lines and a second substrate opposing the first substrate. The display also includes a plurality of common electrodes corresponding to respective pixels, a plurality of sensing electrodes on the second substrate, a touch controller to supply a channel selection signal and a touch control signal to a common electrode driver during a touch driving period, and a common electrode driver to progressively supply a touch driving signal to the common electrodes based on the channel selection signal. The touch driving signal may have the same frequency as the touch control signal.
