Problems solved by technology

Due to the combination of the metal body and the capacitive screen, the screen is often the most vulnerable to explosion or burning. Therefore, how to prevent the screen from burning is related to people's personal safety.
[0004] The existing flame-retardant screens are all designed for external fire sources, and there is no touch screen specially designed for internal combustion or explosion of mobile phones.

Embodiment Construction

[0013] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0014] Such as figure 1 The shown capacitive touch screen includes the uppermost tempered glass layer 1, the anti-blue light layer 2 coated on the lower surface of the tempered glass layer 1, the ITO layer 3 arranged on the lower surface of the anti-blue light layer 2, and the ITO layer 3 The display screen 4 on the lower surface is provided with a flame retardant film 5 at the bottom of the display screen 4 . The ITO layer 3 is a single-sided single-layer ITO pattern structure. The flame retardant film 5 covers the bottom surface of the ITO layer 3 and the tempered glass layer 1 , the anti-blue light layer 2 , the display screen 4 and the sides of the ITO layer 3 to form a coating structure.

[0015] In the present invention, the internal part of the mobile phone of the capacitive touch screen is covered by the flame-retardant film 5, so as...

Abstract

The invention belongs to the technical field of touch display screens and provides a capacitive touch screen for the problem of threat to personal safety of a user due to screen combustion caused by potential combustion explosion hazards of an existing intelligent mobile phone battery. The capacitive touch screen comprises a tempered glass layer of an uppermost layer, an anti-blue light layer applied to the lower surface of the tempered glass layer, an ITO layer arranged on the lower surface of the anti-blue light layer, and a display screen arranged on the lower surface of the ITO layer, wherein a flame retardant film is arranged at the lower part of the display screen. Through blockage of the flame retardant film, a combusted battery can be prevented from igniting the screen; and in combination with a metal machine body, the combustion intensity can be greatly reduced, so that the personal safety of the user is protected.

Description

technical field [0001] The invention belongs to the field of touch screens, in particular to a capacitive touch screen. Background technique [0002] With the advent of the first-generation iPhone, capacitive touch screens have become the standard configuration of mobile phones. In recent years, mobile phones with metal bodies have become more and more popular. [0003] Although smartphones are getting more and more advanced, they still face some problems. For example, in 2016, the flagship models of several large international mobile phone companies all had mobile phone battery problems, and one of them even had a serious battery explosion problem, posing a threat to people's personal safety. Due to the metal body and capacitive screen, the screen is often the most vulnerable to explosion or burning. Therefore, how to prevent the burning of the screen is related to people's personal safety. [0004] Existing flame-retardant screens are all designed for external fire sourc...
