Capacitive touch screen: ITO (a transparent conductive material) layer is used to form a matrix distribution, with X-axis and Y-axis cross distribution as the capacitance matrix. When the finger touches the screen, through the X, Y axis scanning, you can detect the change of capacitance at the touch location, and then calculate the location of the finger. This technology works by utilizing the current sensing of the human body. When the finger touches on the metal layer, a coupling capacitance is formed between the user and the surface of the touch screen due to the electric field of the human body. For high-frequency currents, the capacitance is a direct conductor, so the finger sucks a very small current from the contact point. This current flows from electrodes on each of the four corners of the touch screen, and the current flowing through these four electrodes is proportional to the distance from the finger to the corners. The controller derives the position of the touch point by precise calculation of the ratio of these four currents.
Large capacitive touchscreens play a vital role in shopping mall navigation systems, providing consumers with an intuitive and convenient interface. The following is a detailed analysis of its role, as well as an overview of the excellent performance required for the touch screen:
1. Provide an intuitive operating interface:
Capacitive touch screen has a smooth operation performance, consumers can easily complete the query, navigation and other operations by touching the icons or buttons on the screen.
The large-size screen can display more information, such as mall floor plan, product distribution, store information, etc., so that consumers can see at a glance.
2. Enhance user experience:
Capacitive touch screen is highly sensitive to touch and has a fast response speed, so consumers can experience a smooth and natural operation feeling.
The operation on the touch screen is usually more intuitive and convenient than the traditional keyboard or button operation, reducing the difficulty of use.
3. Realize intelligent navigation:
Shopping mall navigation systems can provide the best path planning solution according to consumer needs, helping consumers quickly find the location of the goods they need.
The map and navigation function on the touch screen can be updated in real time to ensure that consumers get the most accurate information.
4. Promote shopping mall marketing:
The touch screen can be used as a promotional platform for shopping malls, displaying promotional information and new product recommendations to attract consumers' attention.
Through the interactive functions on the touch screen, such as message boards, evaluation systems, etc., consumers can participate in the interactive activities of the mall to enhance the visibility and reputation of the mall.
The touch screen needs to have excellent performance:
1. high sensitivity:
Touch screen needs to have high sensitivity, can accurately identify the consumer's touch operation, to avoid accidental touch or leakage of touch.
2. fast response:
The response speed of the touch screen needs to be fast enough to provide a smooth operating experience. A faster response time reduces consumer waiting time and improves overall user satisfaction.
3. High durability:
Touchscreens need to be able to withstand frequent touch operations, as well as possible physical damage such as scratches and impacts. Therefore, high durability is required to ensure long-term stable operation.
4. Good light transmission:
For large-size touchscreens, good light transmission ensures that the screen is clearly visible in all light conditions. This helps to enhance the consumer experience, especially in low-light environments.
5. Support multi-touch:
Multi-touch enables consumers to operate multiple areas at the same time, enabling more complex operational commands. This is especially important on large touchscreens, where consumers may need to view and manipulate multiple pieces of information at the same time.
6. Stability and reliability:
Touchscreens need to have a high degree of stability and reliability to ensure that they do not malfunction or become incorrect over long periods of time. This helps maintain the normal operation of the mall's navigation system and enhances consumer trust and satisfaction.
7. Special surface treatment:
Anti-glare: Reduces glare by reducing the amount of light reflected from the screen or surface and distributing the light more evenly. This treatment reduces screen reflections and glare, reduces eye fatigue and discomfort, and improves the user's visual comfort. In the bright light environment, it can also ensure that the screen content is clearly visible, improve readability, improve the overall quality of the product, so that it is more in line with the user's needs.
Anti-fingerprint: This prevents fingerprints and other stains from adhering to the screen, mainly by forming a special coating on the surface, while being easy to clean. Users will not feel uncomfortable or affected by fingerprints and stains when using the product. At the same time, by preventing the adhesion of stains and fingerprints, the wear and corrosion on the surface can be reduced, thus extending the service life of the product.
Antimicrobial: Mainly by coating the surface with a layer of material with antimicrobial ability, the growth and reproduction of bacteria is inhibited, thus reducing the risk of bacterial transmission Through the antimicrobial treatment, the hygienic level of the product can be enhanced, providing a safer and healthier environment for the user to use the product.
