In-cell touch panel and display device

摘要

An in-cell touch panel and a display device are configured to address mutual interference between touch signals and image display signals and increase opening ratio of the in-cell touch panel at the same time. The in-cell touch panel includes a color filter substrate and an array substrate disposed opposite to form a cell, a plurality of sub-pixel units arranged in matrix are disposed on said array substrate, and further includes: a plurality of touch sensing electrodes distributed in a column direction of said sub-pixel units on said color filter substrate, and a plurality of touch driving electrodes distributed in a row direction of said sub-pixel units on said array substrate, every two adjacent rows of sub-pixel units constituting a sub-pixel unit group and gate lines for providing gate signals to these two rows of sub-pixel units being disposed between these two rows of sub-pixel units; wherein said touch driving electrodes are located in non-display areas between said sub-pixel unit groups.
