具体实施方式Detailed ways

The electric signal from each touch electrode is transmitted.

然而，由于各触控电极与控制器之间的距离存在差异，使得用于连接触控电极和控制器的触控引线长度不同，在多个触控引线中，线长最长的触控引线与线长最短的触控引线的线长之差会超过线长最长的触控引线线长的50％，且各触控引线的截面面积相同，从而使线长不同的触控引线之间的电阻差异较大，进而对触控引线所传输至控制器的电信号强度产生影响，使得触控面板的均一性差，影响触控面板的触控效果。However, due to the difference in the distance between each touch electrode and the controller, the lengths of the touch wires used to connect the touch electrodes and the controller are different. Among the multiple touch wires, the touch wire with the longest wire length The difference between the length of the touch wire with the shortest wire length and the length of the touch wire with the longest wire length will exceed 50% of the length of the touch wire with the longest wire length, and the cross-sectional area of each touch wire is the same, so that the difference between the touch wires with different wire lengths The resistance of the touch panel has a large difference, which in turn affects the strength of the electrical signal transmitted to the controller by the touch lead wire, which makes the uniformity of the touch panel poor and affects the touch effect of the touch panel.

针对上述技术问题，本申请实施例提供一种触控面板和显示装置，通过将多条触控引线同层设置，并将多条触控引线与触控电极层异层设置，从而减小布置于触控电极层的多个触控电极与多个触控引线产生相互干扰的可能性；在多条触控引线中，任意两条触控引线的线长之差小于或等于线长最长的触控引线线长的10％，以使多条触控引线的线长更加均匀，从而相对于相关技术中触控面板所应用的直线型触控引线，本申请实施例的触控面板能够减小多条触控引线之间电阻的差异，提高了触控面板的均一性，改善触控面板触控效果。In view of the above technical problems, the embodiment of the present application provides a touch panel and a display device, by arranging a plurality of touch leads in the same layer, and arranging a plurality of touch leads and touch electrode layers in different layers, thereby reducing the layout The possibility of mutual interference between multiple touch electrodes and multiple touch leads on the touch electrode layer; among multiple touch leads, the difference between the lengths of any two touch leads is less than or equal to the longest line length 10% of the length of the touch leads, so that the lengths of the multiple touch leads are more uniform, so that compared with the linear touch leads used in the touch panel in the related art, the touch panel of the embodiment of the present application can The resistance difference between multiple touch leads is reduced, the uniformity of the touch panel is improved, and the touch effect of the touch panel is improved.
