The invention discloses a touch screen and a manufacturing method thereof as well as a display device. The touch screen comprises a substrate base plate, and a first touch electrode, a first insulating layer and a second touch electrode which are arranged on the substrate base plate in sequence, wherein the first touch electrode and the second touch electrode are mutually crossed and are of a metal lattice shape; the touch screen further comprises a first signal line which is electrically connected with the first touch electrode, and a second signal line which is electrically connected with the second touch electrode; and metal protection layers are arranged on the first signal line and the second signal line located in a binding region of the touch screen. The metal protection layers are arranged on the first signal line and the second signal line located in the binding region of the touch screen and can be used for protecting the first signal line and the second signal line, so that the anti-corrosion capability of the touch screen is integrally improved, and furthermore, the final yield of a product can be improved through corrosion resistance dependence authentication.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a touch screen, a manufacturing method thereof and a display device. Background technique [0002] At present, the touch screen is a new type of human-computer interaction input method. Compared with the traditional display, keyboard and mouse input methods, the input of the touch screen is simpler, more direct and more convenient. Whether it is a variety of inquiry machines, mobile phones, tablet computers, or electronic whiteboards used in education and business, all have touch display technology, which has become very popular in our daily life and work, and has become an indispensable part. [0003] For capacitive touch screens, Indium Tin Oxide (ITO) is often used as the main conductive material for making electrodes. However, the indium metal in ITO is one of the rare metals with the lowest storage capacity in nature. The cost is high, and the industrial sustainability is ...
