Capacitive touch screen convenient to use

Abstract

The invention relates to the technical field of capacitive touch screens, and discloses a capacitive touch screen convenient to use. The capacitive touch screen includes a bottom plate, and a shell isarranged on the outer surface of the upper end of the bottom plate. A screen protection shell is arranged on the outer surface of the upper end of the shell. A touch display screen is arranged on theouter surface of the front portion of the screen protection shell. A printing device is arranged on the outer surface of the front end of the shell. A bill outlet is formed in the outer surface of the front end of the shell; a placement groove is formed in the outer surface of the side end of the screen protection shell, a first clamping groove is formed in the outer surface of the front end of the placement groove, a second clamping groove is formed in the lower end of the first clamping groove, a main point touch pen is arranged at the upper end of the first clamping groove, and a rotatingshaft is arranged on the outer surface of the upper end of the shell. The capacitive touch screen convenient to use has the characteristics that the capacitive touch screen can be flexibly adjusted, the user experience is improved, the operation is simple, the use is convenient, the dust is prevented, the space is saved, the disassembly and the maintenance are convenient, the connectivity is strong, and the like.

Description

technical field [0001] The invention relates to the technical field of capacitive touch screens, in particular to an easy-to-use capacitive touch screen. Background technique [0002] Capacitive touch screen technology uses the current induction of the human body to work. When the finger touches the metal layer, due to the electric field of the human body, a coupling capacitor is formed between the user and the surface of the touch screen. For high-frequency current, the capacitor is a direct conductor, so The finger sucks a small current from the contact point, and the current flows out from the electrodes on the four corners of the touch screen respectively, and the current flowing through these four electrodes is proportional to the distance from the finger to the four corners, the controller passes these four Accurate calculation of the current ratio, resulting in the location of the touch point. [0003] The existing capacitive touch screen has certain disadvantages wh...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the present invention provides an easy-to-use capacitive touch screen, which has an adjustable capacitive touch screen angle, improves user experience, solves the problem that the capacitive touch screen cannot adjust the screen angle, and adds a main point stylus that can be used. The touch mode is added to increase the range of applicable people, and the advantages of easy disassembly and maintenance solve the problem of complicated disassembly of the capacitive touch screen and inconvenient internal maintenance. It has dust-proof and protective devices, saves space, and solves the problem of The capacitive touch screen works for a long time and is prone to dust problems
