Example Embodiment
[0041] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, the drawings only show some but not all of the contents related to the present invention.
[0042] In the prior art, in order to realize the capacitive touch function, the touch sensing electrodes are usually arranged on the side of the color filter substrate away from the array substrate, and the common electrodes arranged in the array substrate are multiplexed as touch drive electrodes, that is, In the display state, the common electrode is used for receiving the common voltage signal, and in the touch state, the common electrode serves as the touch driving electrode and is used for receiving the touch driving signal.
