Problems solved by technology

[0005] However, the ITO layer as a transparent conductive layer is usually prepared by ion beam sputtering or evaporation. During the preparation process, a high vacuum environment and heating to 200-300°C are required. Therefore, the preparation cost of the ITO layer higher
In addition, after the ITO layer is continuously bent, the resistance at the bend increases, and as a transparent conductive layer, it has the disadvantage of not having good mechanical and chemical durability.
In addition, since a plurality of dot-shaped spacers are usually arranged at intervals between the upper transparent conductive layer and the lower transparent conductive layer in the form of dots, the distance between the upper transparent conductive layer and the lower transparent conductive layer in the non-pressed state is realized by it. Electrical insulation performance is not good enough

Description

technical field [0001] The invention relates to a touch screen and a display device. Background technique [0002] In recent years, along with the high performance and diversification of various electronic devices such as mobile phones and touch navigation systems, there has been an increase in the number of electronic devices in which a light-transmitting touch panel is mounted on the front of a display such as a liquid crystal display. A user of an electronic device uses the touch screen to visually confirm the display content of the display located on the back of the touch screen, and to operate by pressing the touch screen with a finger or a pen. Thereby, various functions of the electronic device can be operated. [0003] According to different working principles and transmission media of touch screens, existing touch screens are usually divided into four types, namely resistive, capacitive sensing, infrared and surface acoustic wave. Among them, resistive touch scree...
