[0005]However, as a transparent conductive layer, the ITO layer is usually prepared by ion beam sputtering or evaporation. During the preparation process, a higher vacuum environment and heating are required. to 200-300°C, therefore, the preparation cost of the ITO layer is relatively high
In addition, as a transparent conductive layer, the ITO layer has disadvantages such as insufficient mechanical properties, difficulty in bending, and uneven resistance distribution.
In addition, the transparency of ITO will gradually decrease in humid air
As a result, existing resistive touch screens and display devices have shortcomings such as insufficient durability, low sensitivity, poor linearity and accuracy.
It can be seen that the touch-type liquid crystal display using the touch screen has the disadvantages of complicated preparation process, high cost, poor durability, low sensitivity, and poor linearity and accuracy.

Abstract
The invention relates to a preparation method for a touch LCD screen, which comprises the following steps: preparing a touch screen which comprises a carbon nanotube layer; forming a polarizing layer on one surface of the touch screen; forming a first alignment layer on the surface of the polarizing layer so as to form an upper substrate; preparing a thin film transistor panel; forming a second alignment layer which covers the thin film transistor panel to form a thin film transistor to form the surface of a thin film transistor; arranging a polarizer on the thin film transistor panel far away from the surface of the second alignment layer and forming a lower substrate; and arranging a liquid crystal layer between the first alignment layer of the upper substrate and the second alignment layer of the lower substrate to form a sandwich structure so as to obtain the touch LCD screen.
Description
technical field [0001] The invention relates to a method for preparing a touch-type liquid crystal display, in particular to a method for preparing a touch-type liquid crystal display based on carbon nanotubes. 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, electronic devices with light-transmitting touch panels mounted on the front of display elements such as liquid crystal displays have gradually increased. [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 screen is the most widely used, please refer to the literature "Production of Transparent ConductiveFilms with Inserted SiO 2 Anchor Layer, and Application to a Resistive TouchPanel" Kaz...
