A transmissive capacitive touch screen is a type of touch screen that uses capacitive touch technology

A transmissive capacitive touch screen is a type of touch screen that uses capacitive touch technology. It has the characteristics of high precision, high response speed, high transparency, and wear resistance, and is suitable for applications such as handwriting, gesture recognition, and multi touch.

     Transmissive capacitive touch screenThe principle is to achieve contact and non-contact detection by measuring the capacitance between the electrode and the glass cover layer. When fingers or other objects approach the screen, the touch point will generate an electric field change. The electric field change will generate an electrical signal in the electric field sensor, which will be amplified and sent to the controller for processing. The controller calculates the coordinates of the approach point through an algorithm and sends them to the computer system for interpretation. This process realizes the detection of input and generates corresponding output signals. This technology can detect multiple proximity points.

The capacitive electrical performance of a transmissive capacitive touch screen directly affects its sensitivity and response speed. In order to improve the electrical performance of the capacitor, a special manufacturing process was adopted to ensure uniform thickness of the glass cover layer. In addition, the glass surface of the touch screen must be polished and coated with a transparent conductive film to ensure transparency and durability. The structure of the entire touch screen is relatively simple, consisting of four layers of glass, conductive film, and circuit board. One layer of glass is the glass cover layer, and the other layer of glass has electrodes. The conductive film is responsible for connecting the electrodes to the touch points, while the circuit board plays a role in signal processing and transmission.

Transparent capacitive touch screens have many applications, such as mobile phones, tablets, interactive projection screens, robots, etc. It has the following advantages:

1. High precision: The transmissive capacitive touch screen has good capacitive electrical performance and can accurately identify the position of the touch point, with high precision.

2. High response speed: Touch points can be detected immediately, and corresponding instructions can be displayed very quickly.

3. Multi touch: The transmissive capacitive touch screen can not only detect one touch point, but also multiple touch points, achieving multi touch and improving user experience.

4. High transparency: The transmissive capacitive touch screen has high transparency and does not affect the display effect.

5. Wear resistance: The surface of the transmissive capacitive touch screen has been specially treated to have the characteristic of wear resistance.

It should be noted that transmissive capacitive touch screens have high sensitivity, so it is important to avoid contact between hands, clothing, and other objects and the screen during use. In addition, specialized cleaning agents and methods should be used during cleaning to protect the surface of the screen.
