Characteristics of LCD Touch Screen for Industrial Control (1)

The new development of LCD touch screen technology makes LCD touch screen more suitable for industrial control applications. The improved sensitivity ensures that when the screen is equipped with protective glass and the user wears gloves for operation, its efficiency can be better than ever before. In addition, the new controller is less sensitive to electrical noise in the environment, and attractive new features are being introduced.

Projected capacitive (P-CAP) touch technology is the dominant technology in the field of industrial touch technology. In addition, P-CAP technology is also widely used in a large number of mobile phones and tablets. Conspicuous design capabilities drive our way to success, including efficient infinite life cycle, full graphic design, and excellent agility. Such functions are also attractive for industrial control applications. The sales volume in the consumer market can reduce the cost, but it will promote the R & D investment, thus promoting the realization of functions, some of which are also applicable to the industrial market such as force recognition (Z-axis detection) and gesture recognition.

High sensitivity

Basically, The key attribute of P-CAP touch technology (such as PCT ™ and MCPT ™）is high sensitivity. It can detect touch operation through very thick cover, protective glass and even thick gloves, so it can achieve unmatched Z-axis sensitivity and control efficiency.

LCD PCAP touch monitor is equipped with a touch controller of excellent design, which can provide a reliable and intuitive touch experience, and can accurately respond to up to 40 touch points. Although many instrument designers think that the user can only touch the screen of LCD with one finger at a time, Multi-Touch PCAP Monitors still have advantages. For example, gesture recognition such as zooming, which is widely used by tablet users, relies on multi-touch recognition. The realization of palm rejection (the screen ignores the hand placed on the screen, but still recognizes and responds to the intentional touch operation), also needs to support multi-touch.

The best touch technology provides excellent performance in demanding applications (when equipped with protective glass and even when operating with gloves). Through the system, data can be collected in real time and detailed fault information of single or more railway vehicles can be compiled. Due to the safety protection of the conductive sensing components by strong and reinforced glass, the sensors are efficiently resistant to scratches, shocks, vibrations, irritating chemicals and extreme temperatures.
