Abstract

The embodiment of the invention provides a touch screen, a display device and a preparation method of the touch screen. The problem that an inorganic film layer on the surface of a display panel in the touch screen falls off is solved. The touch screen comprises a display region and a peripheral region located on the periphery of the display region. The display panel comprises at least one retaining wall, and the retaining wall is located in the peripheral region; the touch panel is arranged on the light-emitting side of the display panel, the touch panel comprises a first metal layer and a second metal layer, and the second metal layer is arranged on the side, away from the display panel, of the first metal layer; the first metal layer comprises a touch auxiliary pattern and a first auxiliary pattern, the touch auxiliary pattern is located in the display region, the first auxiliary pattern is located in the peripheral region, and the orthographic projection of the first auxiliary pattern on the display panel is overlapped with the orthographic projection of the retaining wall on the display panel; the first auxiliary pattern is a solid pattern; the second metal layer comprises a touch control pattern which is located in the display region.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a touch screen, a display device and a method for preparing the touch screen. Background technique [0002] With the development of display technology, display devices with touch screens are favored because of their simple and convenient operation and better experience for users. The touch screen includes a display panel and a touch sensor panel (TSP for short), and the touch panel is disposed on the light emitting side of the display panel to facilitate touch operation. The touch panel can be fabricated by a flexible multi-layer on cell (FMLOC) process, and usually the touch panel includes multiple film layers. [0003] However, when using the FMLOC process to manufacture some of the film layers in the touch panel, it is necessary to use water-containing processes such as water washing, gluing, and development. Cracks enter the display panel, causing the problem that the inor...
