Capacitive touch screen is a touch screen technology that works by using human current sensing. It is plated on the glass screen through a transparent film conductor layer, and in the conductor layer plus a protective glass, forming a double-glass design to protect the conductor layer and the inductor. When the finger touches the screen, due to the role of the human body's electric field, a coupling capacitance is formed between the finger and the conductor layer, and the change of this capacitance is measured to determine the touch position.
With the advancement of intelligent manufacturing and industry 4.0, capacitive touch screen has a broad application prospect in the industrial field. Especially in the pharmaceutical industry, with the continuous improvement of automation and intelligence level, capacitive touch screen will become an important part of pharmaceutical equipment control. In the future, capacitive touch screen will pay more attention to the user experience, operational simplicity and intelligent integration, providing more efficient, accurate and reliable control solutions for the pharmaceutical industry. At the same time, with the continuous progress of technology and cost reduction, capacitive touch screen is expected to be widely used in more industrial areas.
Capacitive touch screen has the following characteristics:
For the industrial pharmaceutical industry, the touch screen used in the production machine, need to have the following key performance:
1. The display should be high-resolution, high brightness: to ensure that the images and text displayed on the screen is clear, to facilitate the precise control of the pharmaceutical process.
2. High touch accuracy: accurately identify the touch operation, reduce the rate of false touch, improve control accuracy.
3. Fast response speed: make instant feedback to touch operation, improve the smoothness of operation.
4. Strong anti-interference ability: maintain stable touch performance in complex industrial environments, free from electromagnetic interference and other influences.
5. Wide operating temperature range: to adapt to the possible temperature changes in the pharmaceutical workshop, to ensure that the touch screen and the monitor can work properly in a variety of temperature conditions.
6. High durability and reliability: able to withstand prolonged use and cleaning of various cleaning agents to maintain long-term stable performance.
7. Multi-touch: Support multiple touch points to operate at the same time, to enhance the user experience.
Capacitive touch screen in the industrial pharmaceutical industry in the application of film machine, showing a number of significant advantages:
1. High precision and sensitivity
Capacitive touch screen through the current induction to achieve touch control, its accuracy and sensitivity is much higher than the traditional touch screen. In the industrial pharmaceutical industry, the operation of pharmaceutical machines requires a high degree of precision to ensure the quality and stability of drugs. Capacitive touch screen can accurately identify the touch position and reduce misoperation, thus improving productivity and product quality.
2. Multi-touch function
Capacitive touch screen supports multi-touch, which means that users can use multiple fingers or tools to operate at the same time. In the pharmaceutical process, this feature can greatly simplify complex operations and improve work efficiency. For example, when adjusting pharmaceutical parameters or performing multi-step operations, multi-touch allows the user to complete the task more flexibly and quickly.
3. Durability and Stability
Industrial pharmaceutical environments are often harsh, and equipment needs to withstand a variety of chemicals, high temperatures, high pressure and other conditions. Capacitive touch screen has a high degree of durability and stability, can be in this environment for a long time stable operation. The surface material usually has good corrosion and wear resistance, to ensure the reliability of long-term use.
4. Easy to clean and maintain
The pharmaceutical industry has strict requirements for hygienic conditions, the equipment needs to be regularly cleaned and maintained. Capacitive touch screen surface smooth, no gap, not easy to stain the dirt, and cleaning process is simple and convenient. This helps to reduce the difficulty and time cost of cleaning, while ensuring hygiene and safety in the pharmaceutical process.
5. Highly integrated and intelligent
Modern industrial pharmaceutical equipment tends to be more and more highly integrated and intelligent. Capacitive touch screen as an important interface for human-computer interaction, can be seamlessly integrated with a variety of intelligent control systems. Through the touch screen, the operator can easily monitor the pharmaceutical process, adjust the parameters, receive alarm information, etc., to achieve intelligent control of the pharmaceutical process.
6. Enhance work efficiency and safety
The application of capacitive touch screen makes the operation of the pharmaceutical machine more intuitive and simple, thus improving work efficiency. At the same time, the intelligent control system can monitor the status of the equipment in real time, find and deal with potential problems in a timely manner, reduce the failure rate, improve production safety.
