Touch screen

Abstract

The invention relates to a touch screen which comprises a touch screen body, a dustproof shell and a dual-purpose shell, the touch screen body is wrapped with the dustproof shell, and the upper end of the dustproof shell is connected with the upper end of the dual-purpose shell through a pin shaft. The problems that a small-size touch screen is usually held by a person for use, the angle position of the screen is usually held after manual adjustment, an external support is usually used for supporting when encountering some things, but an existing support is fixed in structure, the angle is difficult to adjust, the person feels uncomfortable when using the support, and the operation is inconvenient can be solved. After the touch screen is used for a long time or in the sun, heat can be gradually gathered on the back face of the touch screen, an existing touch screen does not have a heat dissipation function, people can only conduct cooling and heat dissipation by means of wind power, the existing touch screen is often exposed in the air, dust is prone to being accumulated on the screen face, and meanwhile the situation that the surface of the existing touch screen is damaged possibly occurs.

Description

technical field [0001] The invention relates to the field of touch screens, in particular to a touch screen. Background technique [0002] Due to its advantages of ease of operation, intuition, and flexibility, the touch screen has become the main means of human-computer interaction for personal mobile communication devices and comprehensive information terminals such as tablet computers, smart phones, and supernotebook computers. Touch screens can be divided into four main types according to different touch principles: resistive touch screens, capacitive touch screens, infrared touch screens and surface acoustic wave SAW touch screens. Among them, the capacitive touch screen has the function of multi-touch, fast response time, long service life and high light transmittance, and the user experience is superior. At present, it has become the main technology used in touch interaction of small and medium-sized information terminals. [0003] The small-sized touch screen has b...

AI Technical Summary

Problems solved by technology

[0004] 1. Small-sized touch screens are usually hand-held by personnel, and the angle of the screen is usually adjusted manually. When something happens, it is usually supported by an external bracket. However, the existing bracket structure is fixed and the angle is difficult to adjust. , people will feel uncomfortable when using it;

[0005] 2. After using the touch screen for a long time or in the sun, the back will gradually gather heat. The existing touch screen has no heat dissipation function, and people can only use external wind to cool down and dissipate heat. Exposure to the air, the screen is prone to dust accumulation, and the surface may be damaged
