Description

Touch components for capacitive panels

technical field

The utility model relates to a design of a touch component used for a capacitive panel, in particular, the touch component can be used to conduct current to a human body.

Background technique

On the market, touch screens can be divided into two types based on the physical principle of detecting touch points: resistive screens, which generate voltage when lightly pressed with fingers or other contacts; capacitive screens, which use fingers to absorb small currents ( Commonly used in touchpads of notebook computers).

The top layer of a resistive touch screen is a polyester sheet with a conductive metal coating on the inside; the bottom layer of the screen, which is attached to the cathode ray tube (CRT) or liquid crystal display (LCD), is a sheet of A glass plate coated with a conductive material. The glass plate and the polyester sheet are separated by tiny "separation points" made of a layer of polyester. Along the x-axis of the glass plate, and the y-axis of the mylar sheet, there are controllers that apply tiny voltage gradients. Whenever a finger or generally a stylus touches the screen, the two conductive layers are laminated together so that the electronic device can detect the X and Y coordinates of the touch point.

In the general market, most of the stylus is used to touch the screen panel. However, the stylus needs to be operated by point pressure. The screen is easy to leave stains and pressure damage marks. Please refer to Figure 1. A conventional resistive stylus includes a tube B, and one end of the pen tube B has a stylus tip B1, wherein the stylus It is a non-conductive plastic pen, but it needs to be operated by point pressure, and the X-coordinate and Y-coordinate of the contact point can be detected to achieve the touch purpose.

At present, the innovative design of the iPhone appears on the market, which combines technology and human nature. Therefore, the iPhone uses a capacitive touch screen with a relatively complicated circuit. The glass plate of the capacitive touch screen is coated with conductive material, covered with a scratch-resistant coating on the outside. Electrodes around the glass plate create a uniform low-voltage electric field on the outer conductive layer; the inner conductive layer provides electromagnetic shielding and reduces noise. Whenever a finger touches the screen, it will generate capacitive coupling with the electric field on the outer conductive layer, and absorb a small current. Each electrode is responsible for measuring the current from each corner, and then the coordinates of the finger are determined by the controller. Therefore, compared with the older resistive touch panel, the touch of the capacitive panel is because the human body is a conductor, the electric field will be changed to generate capacitive coupling, and the touch position can be judged by detecting the current , so the capacitive panel can only rely on the human body or contact with conductive objects to change the current to achieve the touch effect.

Therefore, iPhone products will not be sensitive to the conventional stylus, because the conventional stylus is non-conductive, and the skin part of the finger that can conduct electricity must be used to operate. However, due to the large area of the finger, the user Often due to the dense and small menu items on the screen, other options are accidentally touched when selecting, which will cause troubles for users in operation. This technology still needs to be improved.

Wherein, the handle part is convenient for the human body to hold, and the contact part is in contact with the capacitive panel, so that the user can operate the panel with the touch component. When the user uses it, the user holds the handle part of the touch component to When touching the panel, the conduction of the touch component can also generate capacitive coupling with the electric field on the outer conductive layer of the panel, and then the human body can absorb a small current to make the electrode measure the current and perform touch operation. The utility model replaces It is more convenient for the user to easily select the desired program or file from the dense and small menu item list due to the familiar hand operation method.
