Touch screen and touch-controlled display device

Abstract

The invention relates to a touch screen and a touch-controlled display device. The touch screen comprises a first touch sub screen and a second touch sub screen, wherein at least one of the first touch sub screen and the second touch sub screen is provided with a carbon nano tube conducting layer, each touch sub screen comprises a touch area and a first peripheral area which is connected to one side of the touch area, each first peripheral area is bent relative to the corresponding touch area so that an included angle can be formed between the first peripheral area and the corresponding touch area, and the first peripheral area of the first touch sub screen is correspondingly fixed to the first peripheral area of the second touch sub screen in an overlapped mode so that the touch area of the first touch sub screen and the touch area of the second touch sub screen can be connected into a whole. The touch screen is large in size and can meet the requirement of people for a large touch screen.

Description

technical field [0001] The invention relates to a touch screen and a touch display device. Background technique [0002] With the vigorous development of flat-panel display technology and the reduction of manufacturing costs, flat-panel display devices with advantages such as low radiation, small thickness, and low power consumption are more and more favored by consumers, and are therefore widely used in electronic products. In order to meet the needs of modern people for a more convenient and intuitive man-machine interface, various flat display devices with touch functions, ie, touch display devices, have gradually been launched on the market in recent years. [0003] Touch display devices can generally be divided into two types: external and built-in. Among them, the external touch display device is based on a traditional flat-panel display device with a touch screen added, so as to integrate the touch function and display function. [0004] In recent years, touch screen...

Problems solved by technology

However, the conductivity of the carbon nanotube conductive layer is related to the length of the carbon nanotubes inside it. Generally, the longer the carbon nanotube is, the worse the conductivity of the carbon nanotube conductive layer formed along the length direction is, This feature greatly limits the size of the carbon nanotube conductive layer

In addition, limited by the size of the carbon nanotube crystal element, the width of the carbon nanotube conductive layer in the vertical direction of the carbon nanotube extension is also difficult to make into a larger size.

That is to say, at present, the carbon nanotube conductive layer is difficult to be made into a larger size, so the touch screen made of the carbon nanotube conductive layer is also difficult to make a large-sized touch screen, so the touch screen made of the existing carbon nanotube conductive layer is difficult to meet Demand for larger touch screens
