Definitions
- the present invention aims to at least solve one of the technical problems existing in the prior art, and proposes a touch panel and a display device, which can improve the uniformity of the display screen, thereby improving the quality of the display screen.
- the present invention provides a touch panel comprising a plurality of touch sensing electrodes and a plurality of touch driving electrodes, wherein the touch sensing electrodes and the touch driving electrodes are different in different planes.
- An illuminating layer is disposed at an intersection of the two, and a plurality of vacant electrodes are formed on a plane of the touch sensing electrode and/or the touch driving electrode to distribute the electrodes on the same plane. Evenly.
- each of the vacant electrodes is a continuous electrode.
- each of the vacant electrodes includes a plurality of spaced and uniformly disposed sub-vacant electrodes.
- all of the sub-vacant electrodes are electrically connected and grounded by a thin wire.
- a tip end is formed at each end of each of the sub-vacant electrodes of each of the vacant electrodes, and adjacent two tips are in contact.
- each of the vacant electrodes is disposed in parallel with the touch sensing electrodes or the touch driving electrodes on a plane in which they are located.
- FIG. 1 is a schematic structural view of a conventional touch display panel
- FIG. 3 is a schematic structural diagram of a touch panel according to a first embodiment of the present invention.
- FIG. 4 is a schematic structural diagram of a touch panel according to a second embodiment of the present invention.
- FIG. 6 is a schematic diagram of a first structure of a touch panel according to a third embodiment of the present invention.
- FIG. 8 is a schematic structural diagram of a touch panel according to a fourth embodiment of the present invention.
- touch sensing electrode Rx and the vacant electrode DRx in the embodiment are both disposed on the inner side of the black matrix; however, the present invention is not limited thereto, and in practical applications, the touch sensing electrode Rx and the vacant The electrode DRx may also not correspond to the black matrix setting, in which case, in order to avoid affecting the display, the two are formed using transparent ITO.
- the high resistance film layer 10 is formed between the black matrix BM and the color film (R, G, and B), and the via hole VH is in contact with the high resistance film layer 10 through the color film.
- the high resistance film layer 10 may also be disposed between the color film substrate CF and the black matrix BM, and the via hole VH is connected to the high resistance film layer 10 through the black matrix.
- the above-mentioned vacant electrode DRx may be erased by other means, for example, by electrically connecting the lead to the vacant electrode DRx, and electrically connecting the lead to the ground.
- each of the sub-vacant electrodes DRx' overlaps only one touch driving electrode Tx, which can completely avoid crosstalk of the plurality of touch driving electrodes Tx.
- FIG. 8 is a schematic structural diagram of a touch panel according to a fourth embodiment of the present invention.
- the touch panel provided in this embodiment is similar to the touch panel provided in the third embodiment, and also includes a touch driving electrode Tx, a vacant electrode DRx, a touch sensing electrode Rx, a color filter substrate CF, and an array.
