Description

technical field [0001] The present application relates to the field of touch technology, in particular to a touch component and a touch display device. Background technique [0002] Capacitive touch screens are widely used in various electronic interactive scene devices due to their high durability, long life, and support for multi-touch functions. The capacitive touch screen detects the specific position touched by the finger by detecting the change of capacitance at the position touched by the finger. [0003] At present, the material of the touch electrode is usually a hollow metal mesh (Metal Mesh) material, and its conductive area is compared with the traditional full-surface transparent Indium Tin Oxide (Indium Tin Oxide, ITO) material touch electrode, and its actual effective conductive electrode The area is small, so the mutual capacitance between the driving electrode TX and the sensing electrode RX of the touch electrode is very small, resulting in a smaller capac...

Problems solved by technology

[0003] At present, the material of the touch electrode is usually a hollow metal mesh (Metal Mesh) material, and its conductive area is compared with the traditional full-surface transparent Indium Tin Oxide (Indium Tin Oxide, ITO) material touch electrode, and its actual effective conductive electrode The area is small, so the mutual capacitance between the driving electrode TX and the sensing electrode RX of the touch electrode is very small, resulting in a smaller capacitance change when touched by a finger, which is not easy to be detected by the touch chip (Touch IC) arrive

[0004] Therefore, it is necessary to propose a technical solution to solve the problem that the mutual capacitance between the driving electrode and the sensing electrode of the touch electrode is small
