Abstract:
1. An in-cell touch panel, comprising: a first substrate comprising a plurality of displaying pixels having thin film transistors (TFTs) and pixel electrodes; a second substrate facing toward the first substrate, the second substrate comprising a plurality of color filtering patterns corresponding to the displaying pixels; a liquid crystal layer arranged between the first substrate and the second substrate; a plurality of touching units arranged between the TFTs and the first substrate, and the touching units are separated from each other; and a plurality of sensing areas and driving areas arranged below the pixel electrodes, and the sensing areas and the driving areas connect to the touching units via conductive through holes; and wherein the touching unit comprises black matrix, both of the driving area and the sensing area comprise a plurality of common electrodes, and the common electrode electrically connects to the black matrix via the conductive through hole passing through at least a first dielectric layer and a second dielectric layer.
