The invention discloses a preparation method of a narrow-frame touch screen, the narrow-frame touch screen and a display device, which are used for solving the problem that a foldable touch screen inthe prior art cannot realize a narrow frame. In the specific implementation, a first metal electrode layer is formed on a substrate, a first metal electrode layer pattern is formed through a composition process, and the first metal electrode layer pattern comprises a channel pattern of a first metal electrode and a wiring block of the first metal electrode; a second metal electrode layer is formedon the first insulating layer; forming a second metal electrode layer pattern through a composition process; wherein the second metal electrode layer pattern comprises a channel pattern of a second metal electrode, a wiring block of the second metal electrode and island metal of the second metal electrode, and the projection of the island metal of the second metal electrode on the substrate covers the projection of the wiring block of the first metal electrode on the substrate; and forming a wire on the second metal electrode layer so as to realize the narrow frame performance of the touch screen.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a preparation method of a narrow-frame touch screen, a narrow-frame touch screen and a display device. Background technique [0002] Flexible display has become an important direction for the development of current display devices. Foldable mobile phone is an implementation form of flexible display, which can be used as an ordinary smartphone in the folded mode, and can be used as a tablet computer when unfolded, thereby satisfying consumers' needs for entertainment display and large-screen display. [0003] With the emergence of flexible AMOLED (Active-matrix organic light-emitting diode, active-matrix organic light-emitting diode) screens, the technical difficulties at this stage have been transferred to corresponding accessories, such as foldable touch screens, flexible covers, flexible batteries, etc. . At present, the conductive layer of the foldable touch screen is mainl...
