Abstract
An in-cell touch panel liquid crystal display device is disclosed. The display device includes a first substrate, a second substrate disposed opposite the first substrate, and a liquid crystal layer disposed between the first substrate and the second substrate. The display device also includes a common electrode layer disposed on a side of the second substrate facing the first substrate, where the common electrode layer includes a plurality of first common electrodes and a plurality of second common electrodes both arranged in a matrix. In addition, the first common electrodes and the second common electrodes are configured to detect a touched position on the in-cell touch panel liquid crystal display device.
