Abstract

The invention discloses an On Cell structure touch display screen and a manufacturing method thereof and a display device, relates to the technical field of liquid crystal display, and aims at solving the problem of high error-reporting rate of an exposure machine in the process of alignment exposure on a plurality of touch layers. The manufacturing method of the On Cell structure touch display screen comprises the steps as follows: a transparent semiconductor layer, a first protection layer, a metal layer and a second protection layer are sequentially manufactured between a color-film substrate and a polarizing plate along a ray propagation direction; alignment marks of the transparent semiconductor layer and the first protection layer are manufactured on a black matrix of the color-film substrate; the used materials are light-shielding materials; the alignment mark of the metal layer is made of a photoresist; and the alignment mark of the second protection layer is made of a reflecting material. The On Cell structure touch display screen is manufactured by the manufacturing method; and the manufacturing method of the On Cell structure touch display screen disclosed by the invention is used for manufacturing the touch screen.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a touch display screen with an OnCell structure, a manufacturing method thereof, and a display device. Background technique [0002] At present, with the development of liquid crystal display technology, people put forward higher and higher requirements for the human-computer interaction function of the liquid crystal display. However, in the existing technology, people generally use the OnCell technology to combine a traditional liquid crystal display screen with a touch sensor to form an OnCell structure touch screen, so as to improve the human-computer interaction function of the liquid crystal display. [0003] Specifically, Oncell technology refers to the method of embedding the touch layer between the color filter substrate and the polarizer of the liquid crystal display, and can be divided into a single-layer touch layer and a multi-layer touch layer accordi...
