In-cell touch panel, touch detection method and liquid crystal display device

A touch control detection method, comprising:

• defining a top region and a bottom region on a driving layer of an in-cell touch panel, wherein the top region and the bottom region are located adjacent to and separately from each other, the top region comprises a first group of driving lines and the bottom region comprises a second group of driving lines;
• and
• sending, by a touch control unit, a first driving signal with a first frequency to scan the top region, and a second driving signal with a second frequency to scan the bottom region simultaneously.

A touch controller, connected to a touch panel comprising a driving layer and a sensing layer which are corporately form a plurality of touch nodes, the sensing layer comprises a plurality of sensing lines connected to the touch controller, the driving layer comprises a top region comprising a first group of driving lines and a bottom region located adjacent to and separately from the top region, wherein the bottom region comprises a second group of driving lines, wherein the touch controller is configured to send a first driving signal with a first frequency to scan the top region, and send a second driving signal with a second frequency to scan the bottom region simultaneously.
