Problems solved by technology

The above-mentioned touch screen needs to use the conductive glue 8 containing gold balls with high cost, which will increase the production cost, and the first connecting terminal 4 on the side of the opposite substrate 1 needs to pass through the first connecting terminal 4 on the side of the array substrate 2. The three connecting terminals 7 are connected to the flexible printed circuit board 9, so that the third connecting terminal 7 arranged on one side of the array substrate 2 will occupy the space of the array substrate 2

Abstract

The invention discloses a touch screen, a manufacturing method thereof and a display device. Due to the fact that an opposite substrate and an array substrate are arranged in a staggered mode, the opposite substrate and the array substrate are overlapped and staggered, the overlapped region of the opposite substrate and the array substrate is provided with a touch electrode, and the staggered region of the opposite substrate and the array substrate is provided with a first wiring terminal which is connected with the touch electrode. Therefore, the first wiring terminal on one side of the opposite substrate does not need electrically connecting to the array substrate so as to omit the usage of high-cost gold-ball-contained conductive adhesive, so that the manufacturing costs can be reduced; besides, the region of the opposite substrate, which needs cutting off in the prior art, is provided with the first wiring terminal connected with the touch electrode, so that the utilization rate of the opposite substrate is improved and meanwhile the space of the array substrate can avoid being occupied.

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] According to the structure, the touch screen can be divided into: Add on Mode Touch Panel, On Cell Touch Panel, and In Cell Touch Panel. Among them, the surface-covered touch screen is to arrange the touch electrodes of the touch screen between the opposite substrate and the polarizer of the display screen, which has a high yield and does not reduce the area of ​​the display area; The touch electrodes are arranged inside the display screen, which can reduce the overall thickness of the module and reduce the production cost of the touch screen. [0003] Take the embedded touch screen as an example, such as figure 1 As shown, it includes an opposite substrate 1 and an array substrate 2. On the side of the opposite substrate 1, a touch electrode 3 and a first connection terminal 4 c...
