Problems solved by technology

[0004] However, since the metal grid itself is opaque, the lines in the display area are easily exposed. Therefore, a small line width (below 5 μm) is required in the process to achieve a good concealment effect, making the preparation process of the metal grid High difficulty

Abstract

The invention discloses a touch panel and a touch device. The touch panel comprises a first touch electrode layer and a second touch electrode layer which are arranged in a different-layer insulationmode; the first touch electrode layer comprises multiple first touch electrodes arranged in parallel, the second touch electrode layer comprises multiple second touch electrodes arranged in parallel,and the extension direction of the first touch electrodes and the extension direction of the second touch electrodes intersect; the first touch electrodes and / or the second touch electrodes are targettouch electrodes, and the target touch electrodes are formed by adopting transparent conducting materials with sheet resistance lower than a preset value; the target touch electrodes are each of a grid structure. According to the technical scheme, on the premise of meeting the low impedance requirements of a large screen touch screen on the touch electrodes and the overall high light transmissionrequirements, the preparation difficulty of the touch electrodes is reduced.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of touch screens, and in particular, to a touch panel and a touch device. Background technique [0002] With the development of electronic technology, touch screens are widely used in mobile phones, digital cameras, media players, navigation systems, PADs, game devices and monitors and other fields. [0003] The touch electrodes of the touch screen in the prior art are mainly formed of indium tin oxide (Indium Tin Oxide, ITO) material, and its square resistance is above 100Ω / port. Due to the high impedance, it can only be applied to some small-sized touch screens. It is not suitable for large-size touch screens that require lower impedance. In order to solve the above problems, a metal grid with low impedance is usually used as the touch electrodes of the large-size touch screen. [0004] However, since the metal grid itself is opaque, the lines in the display area are easily exposed,...
