Abstract:
1. A touch-sensing LCD panel, comprising: an active device array substrate comprising: a first substrate; a pixel array disposed on the first substrate, wherein the pixel array comprises a plurality of sub-pixels arranged in an array, a plurality of scan lines, and a plurality of data lines, each of the sub-pixels includes an active device and a pixel electrode electrically connected to the active device, and each of the pixel electrodes is overlapped with one of the adjacent scan lines; a plurality of touch-sensing pads disposed on the first substrate; an electric field shielding layer disposed on the pixel array and arranged between the pixel electrodes of the sub-pixels adjacent to each other for shielding electric fields of the adjacent sub-pixels, wherein the electric field shielding layer is disposed on the edge of the pixel electrode and on the edge of the adjacent pixel electrode, and wherein the electric field shielding layer is overlapping over only a portion of the scan line, wherein the electric field shielding layer includes a mesh pattern and a material for the electric field shielding layer is a dielectric material; an opposite substrate comprising a common electrode and a plurality of touch-sensing protrusions disposed above the touch-sensing pads; and a liquid crystal layer disposed between the active device array substrate and the opposite substrate.
