Problems solved by technology

[0003] The most commonly used touch screen in our life is capacitive touch screen. There are many types of this touch screen, which can realize single-point or multi-point touch operation with high precision. Capacitive touch screen is often used in our mobile phones. However, capacitive The type touch screen can only realize the touch operation in the X-axis and Y-axis directions at most, and cannot sense the force of the touch, and because the current touch screen generally adopts a common stacking method, the overall structure of the touch screen is too thick. The way of bonding or lamination will lead to troublesome assembly process

Embodiment 1

[0019] A simple and practical touch screen structure of this embodiment, such as figure 1 As shown, it includes a rear case 7; a battery 5 and a main board 6 located on the rear case 7, and the battery 5 and the main board 6 are arranged side by side; a middle frame located on the battery 5 and the main board 6; a shielding layer 8 located on the middle frame 4 The liquid crystal display screen 3 on the shielding layer 8; the electromagnetic pen antenna 2 located on the liquid crystal display screen 3; the touch screen 1 located on the electromagnetic pen antenna.

[0020] The electromagnetic pen antenna 2 includes a digital board, the digital board in the electromagnetic pen antenna 2 emits an AC electromagnetic field through the antenna, the electromagnetic pen receives the energy of the AC electromagnetic field and stores it, and the magnetic flux changes when the electromagnetic pen is close to the induction, and a specific The electromagnetic signal of the frequency is se...

Embodiment 2

[0027] This embodiment selects the capacitive touch screen of G / G technology as an example. The capacitive touch screen of G / G technology refers to a capacitive screen made of surface tempered glass and a touch screen made of glass GLASS material, and the electromagnetic pen antenna is respectively arranged on the glass The rest of the structure of the upper and lower surfaces of the touch screen made of GLASS is the same as that of Embodiment 1, so it will not be described again.

Embodiment 3

[0029] This embodiment selects the capacitive touch screen of G / F / F technology as an example. The capacitive touch screen of G / F / F technology refers to a capacitive screen made of surface toughened glass and a touch screen made of two layers of thin film FILM materials, while the electromagnetic The pen antennas are respectively arranged on the FILM of the touch screen made of two layers of film FILM, and the rest of the structure is the same as that of Embodiment 1, so it will not be described again.

Abstract

The invention discloses a simple and practical touch screen structure: comprising a back shell; a battery and a main board on the back shell, the battery and the main board are arranged side by side; a middle frame on the battery and the main board; a shield on the middle frame layer; a liquid crystal display on the shielding layer; an electromagnetic pen antenna on the liquid crystal display, and the electromagnetic pen antenna is made of a transparent conductive film; a touch screen on the electromagnetic pen antenna. The improvement of the structure of the present invention not only realizes the touch operation in the X-axis and Y-axis directions on the touch screen, but also realizes the touch operation in the Z-axis direction by sensing touch, and reduces the thickness and assembly process. Manufacturing costs are reduced.

Description

technical field [0001] The invention relates to the field of touch screens, in particular to a simple and practical touch screen structure. Background technique [0002] Although touch screen technology has only been used in my country for more than 10 years, it has become the most acceptable computer input method for ordinary people after keyboard, mouse, tablet and voice input. Because of this technology, the user can operate the host computer by lightly touching the icons or text on the computer display screen with his fingers, which provides a good and friendly interactive interface and eliminates the need for users to face such things as the keyboard when operating the computer. Fear and confusion when waiting for interactive equipment, thus making the human-computer interaction more straightforward, which greatly facilitates those users who do not understand computer operations. At the same time, this human-computer interaction method gives multimedia a new look and is...
