Problems solved by technology

[0005] However, as a transparent conductive layer, the ITO layer has disadvantages such as insufficient mechanical and chemical durability, and there is a phenomenon of uneven resistance and a small range of resistance values.
As a result, existing touch screens have disadvantages such as poor durability, low sensitivity, and poor accuracy.

Abstract

The invention relates to a touch screen. The touch screen comprises a first electrode plate and a second electrode plate, wherein, the first electrode plate comprises a first transparent conducting layer, the second electrode plate comprises a second transparent conducting layer, and the second transparent conducting layer is oppositely spaced from the first transparent conducting layer; at leastone of the first transparent conducting layer and the second transparent conducting layer is a carbon nanotube layer composed of a plurality of carbon nanotubes, and the carbon nanotubes are arrangedin a preferred orientation manner along the same direction; and a transparent insulator is arranged between a first substrate and a second substrate, and the refractive index of the transparent insulator is greater than that in vacuum. The carbon nanotube layer has the characteristics of lower resistance and good flexibility, and the refractive index of the transparent insulator is greater than that in vacuum, therefore the touch screen has the advantages of better durability, better sensitivity and better accuracy. The invention further provides a display device using the touch screen.

Description

technical field [0001] The invention relates to a touch screen and a display device, in particular to a touch screen using carbon nanotubes and a display device using the touch screen. 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 such an electronic device performs operations by pressing the touch panel with a finger, a pen, or the like while visually confirming display contents on a display located behind the touch panel through the touch panel. 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 divided into four types, nam...
