[0003] Wherein, for a touch panel with an externally embedded structure, the touch chip 101 is arranged outside the touch panel, for example, on a control board (circuit board, provided with electronic components and circuits other than the panel assembly), and the touch panel Each receiving line 111 and each sending line 121 are separately led out and connected to the control board, and each line needs to occupy the joint end space where the control board is connected to other peripheral components. The receiving line 111 and the sending line 121 The number of the control panel is related to the touch precision, the size of the control board is limited, the size of its joint is limited, and the space that can be allocated to the touch panel is limited, which is not conducive to the improvement of the touch precision of the touch panel and limits the design of the touch panel. Leading out a large number of communication lines, the cost is high

Embodiment Construction
[0032]Hereinafter, various embodiments of the present invention will be described in more detail with reference to the accompanying drawings. In the various drawings, the same elements are represented by the same or similar reference numerals. For the sake of clarity, the various parts in the drawings are not drawn to scale.
[0033]The specific embodiments of the present invention will be described in further detail below in conjunction with the drawings and embodiments.
[0034]Figure 2A ,Figure 2B withFigure 2C Shows a schematic diagram of the touch panel structure according to the first embodiment of the present invention, such asFigure 2A~Figure 2CAs shown, the touch panel 200 of the first embodiment of the present invention includes a receiving layer 210 and a sending layer 220. The receiving layer 210 and the sending layer 220 are stacked and connected to the touch chip 201 to transmit touch information. The receiving layer 210 An insulating layer 230 is provided between the receiv...

The invention discloses a touch panel and a touch device, the touch device comprises the touch panel, the touch panel comprises a sending layer and a receiving layer, the sending layer comprises a sending electrode and a sending wire laid on the sending electrode, the receiving layer comprises a receiving electrode and a receiving wire laid on the receiving electrode, at least one of the sending wire and the receiving wire is a single wire, and the two ends of the single wire are connected to the touch control chip and used for transmitting touch control information. According to the touch panel, at least one of the sending wire and the receiving wire is the single wire, the number of the leading-out wires for transmitting the touch information with the touch chip is reduced, the cost canbe reduced, the width of the joint end of the touch panel can be reduced by adopting the touch device of the touch panel, and the cost is reduced.
Description
Technical field[0001]The present invention relates to the field of display technology, in particular to a touch panel and a touch device.Background technique[0002]The in-plane design of the touch panel (TP) traces of the on-cell structure touch panel in the prior art is divided into two layers.Figure 1A withFigure 1B Shows a schematic diagram of the wiring structure of a touch panel according to the prior art, such asFigure 1A withFigure 1B As shown, correspondingly, the two layers include a receiving layer 110 and a sending layer 120. The receiving layer 110 includes receiving electrodes (not shown in the figure) and receiving traces 111 covering the receiving electrodes. Each receiving trace 111 is separate Lead and connect to the touch chip 101, obtain the potential information of each receiving electrode, and provide it to the touch chip 101; the sending layer 120 includes sending electrodes (not shown in the figure) and sending wires 121 covering the sending electrodes, each Th...
