Problems solved by technology

Among them, surface acoustic wave touch screen (surface acoustic wave technology) is the only technology that can sense touch pressure in the existing touch screen technology, but because this technology cannot be applied to large size, it is too sensitive to surface contamination, it is easy to be disturbed by sound, and it is difficult to realize multi-point Many defects such as touch control and difficulty in perceiving static pressure are still unable to enter mainstream applications, such as mobile phones and tablet computers, so it is difficult to become mainstream

Embodiment Construction

[0024] The display screen touch unit and its manufacturing method of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments of the present invention.

[0025] figure 1 It is a structural schematic diagram of the pressure-sensitive display screen touch unit of the present invention. Such as figure 1 As shown, it describes the most basic unit of a touch pressure sensor, which is mainly composed of an upper electrode (drive electrode) 101 , a lower electrode 102 and an ultra-thin dielectric layer 103 in the middle. in:

[0026] Both the upper electrode 101 and the lower electrode 102 are transparent or translucent conductors, and their materials can be but not limited to indium tin oxide (ITO), aluminum-doped zinc oxide (AZO), fluorine-doped tin oxide (FTO), doped Gallium zinc oxide (GZO), graphene, metal nanowire arrays, etc. Its general film thickness and preparation methods are well known in the industr...

Abstract

Disclosed are a pressure-sensitive display touch unit, a touch screen, and a manufacturing method thereof. The touch unit mainly comprises a drive electrode, a lower electrode, and a dielectric layer between the drive electrode and the lower electrode. When a pressure is applied between the drive electrode and the lower electrode, a tunnel current IT is formed, and a voltage VT exists between the drive electrode and the lower electrode. By using the touch unit of the present invention, an external pressure can be converted into a current signal, and the pressure becomes an information input manner. Further, by combining the touch unit of the present application with an existing capacitive touch screen or resistive touch screen, the touch unit not only can possess the existing multi-point touch function, but also can sensitively sense the change in pressure and enhance the function of the existing touch screen, providing more operational applications for the touch screen.

Description

technical field [0001] The invention relates to touch control and display screen technologies, in particular to a pressure-sensitive display screen touch unit, a touch screen and a manufacturing method thereof, which are used for the basic sensing unit of the touch screen. Background technique [0002] Existing touch screens mainly use methods such as capacitance, resistance, surface acoustic wave, and optics to sense touch actions. Among them, surface acoustic wave touch screen (surface acoustic wave technology) is the only technology that can sense touch pressure in the existing touch screen technology, but because this technology cannot be applied to large size, it is too sensitive to surface contamination, it is easy to be disturbed by sound, and it is difficult to realize multi-point Many defects, such as touch control and difficulty in sensing static pressure, are still unable to enter mainstream applications, such as mobile phones and tablet computers, so it is diffi...
