Abstract

The invention discloses a touch panel and a display device.The touch panel comprises a plurality of first touch electrode chains, a plurality of second touch electrode chains and a plurality of auxiliary electrodes, each first touch electrode chain comprises a plurality of first touch electrodes, each second touch electrode chain comprises a plurality of second touch electrodes, and each auxiliary electrode comprises a plurality of auxiliary electrodes; The second touch electrode chains and the first touch electrode chains intersect and are arranged in an insulated mode, the auxiliary electrodes, the second touch electrode chains and the first touch electrode chains are arranged in an insulated mode, and when the touch panel is in a mutual capacitance scanning stage, mutual capacitance is formed between the second touch electrode chains and the first touch electrode chains. The plurality of auxiliary electrodes are electrically grounded; According to the scheme, a branch through which charges flow out through fingers is added, and the working reliability of the touch panel in a mutual capacitance state is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to the field of display panel manufacturing technology, in particular to a touch panel and a display device. Background technique [0002] The flexible display technology can realize the folding of the screen. In order to achieve a better folding effect, the cover of the screen needs to be made thin enough. [0003] However, for the mutual capacitance state of the touch panel, if the cover plate of the screen is too thin, the distance between the finger and the touch electrode will be reduced, and the capacitance between the finger and the touch electrode will be increased, resulting in a touch operation that should have The charge taken away by the human body returns to the touch chip through the touch electrode, that is, the change of charge detected by the touch chip will be reduced, which interferes with the normal operation of the touch chip and reduces the reliability...
