Capacitive in cell touch panel and display device
The present invention discloses a capacitive in cell touch panel and display device, wherein touch sensing electrodes are provided on a color filter substrate, the whole common electrode layer of the TFT array substrate is segmented into a plurality of strip-shaped structures functioning as touch driving electrodes, and the touch driving electrodes are driven in a time-sharing manner to achieve the touch function and the display function in a time-sharing manner. Since in the touch panel according to the present invention, structure of the common electrode layer of the TFT array substrate is altered to form the touch driving electrodes, it is not necessary to add a new film on the existing TFT array substrate and only an additional process needs to be added to segment the whole common electrode layer into a plurality of strip-shaped structures, reducing the production cost and increasing the production efficiency.
