Claim:
1. An in-cell touch panel comprising: an array substrate comprising gate lines and a common electrode layer, and an opposing substrate disposed oppositely to the array substrate, wherein: the common electrode layer of the array substrate comprises a plurality of sub-electrodes arranged in an array; spaced sub-electrodes in each column of the sub-electrodes serve as touch driving sub-electrodes constituting a touch driving electrode, and sub-electrodes other than the touch driving sub-electrodes serve as common sub-electrodes; during line-by-line scanning of the gate lines covered by each row of sub-electrodes, sub-electrodes in the row are used to be applied with common electrode signals for conducting a displaying function, touch driving sub-electrodes in rows other than the row of sub-electrodes are used to be applied with touch driving signals for conducting a touch driving function, and common sub-electrodes in rows other than the row of sub-electrodes are used to be applied with common electrode signals; in a non-display area the array substrate is provided with display control lines and touch control lines in one-to-one correspondence with sub-electrode rows comprising touch driving sub-electrodes; each display control line corresponding to a corresponding row of sub-electrodes is connected with a gate line covered by the row of sub-electrodes via a turning-on switching device, and is connected with a last-scanned gate line covered by the row of sub-electrodes via a turning-off switching device, and a control end of the turning-off switching device is connected with a touch control line corresponding to the row of sub-electrodes; and the turning-on switching device and the turning-off switching device are configured to let the display control line have control signals with opposite polarities when the gate line covered by the row of sub-electrodes is scanned and when the scanning is completed.
