With the continuous expansion of the application of industrial all-in-one panel PC in industrial automation, it has been widely used in intelligent workshop, CNC machine tools, industrial robot control, machine vision detection, AGV, logistics sorting, power cabinet and other industrial fields. Among them, based on the demand of intelligent management in today's electrical room, the use of industrial all-in-one PC in the power cabinet has gradually become hot in industry application.

1.Industry demand

As the touch display equipment applied in the cabinet of the electrical room, the industrial all-in-one tablet PC has high requirements in terms of configuration, stability and anti-interference due to the characteristics of the electrical room, such as a variety of complex data processing, multiple frequency converters, strong voltage interference and closed space.

In addition, as a professional industrial touch display equipment manufacturer, Touch Think, based on its own years of industry experience, as well as the good feedback from customers, the application of industrial all-in-one tablet PC in the electrical room cabinet, its touch screen technologies has become the main focus for majority of users. At present, the touch screen technologies of industrial all-in-one tablet PC mainly include resistance screen, capacitance screen, infrared touch screen, surface acoustic screen, etc., but the resistance screen and capacitance screen are the main choice in market.

2. Solutions

Therefore, based on the real needs of the application scenario of the cabinet in the electrical room, Touch Think relies on the actual case of its own products, while answering user's questions, and providing a specific product application scheme to help the user solve problem more pertinently.

Before understanding the application of the product, we should first figure it out about the difference between the capacitive touch screen and resistive touch screen of the industrial all-in-one tablet PC.

1. Difference between resistive screen and capacitive screen

1) Resistive screen: commonly known as "soft screen", which is divided into three layers in structure. The inner layer is glass, the outer layer is film, and ITO (indium tin metal oxide) is coated on the side adjacent to the film and glass.

Working principle: in short, resistive screen is actually a kind of sensor. When the resistance screen is operated, when the two layers of film and glass collide with each other, the current will have an impact. According to the data between the calculated force and current, the chip evaluates which position of the screen is under pressure and reacts. Due to the resistance screen is force touch, so this principle leads to the resistance screen can only touched by one point, it is difficult to achieve multi touch. This principle also makes the resistance screen of the industrial all-in-one tablet PC mainly used in the harsh industrial scenarios where full of dust, large temperature difference and it support operation with gloves.

2) Capacitive screen: commonly known as "hard screen", which is a four layer composite glass screen. The first layer is ITO to ensure the working environment, the second layer is glass, and the third layer is ITO coating for the working surface; the fourth layer is silica glass protective layer.

Working principle: the capacitive screen actually works by using the current induction of human body, which can be understood as requiring touch medium with bioelectricity to touch. In other words, the capacitive screen uses the lower layer to transmit signals to the upper layer. When the upper layer is contacted by the conductor, the lower layer can quickly receive messages and make calculations. Locate and respond to finger contact. Because of this, the capacitive screen can not only support multiple points at the same time, but also greatly improve the sensitivity when touching by fingers. Therefore, the capacitor screen is mostly used in normal industrial application scenarios which without special requirements.

3) Electrical cabinet users prefer capacitive touch mode

Based on the working principle of the above two touch modes and the demand of Touch Think's own users feedback, most of the electrical room cabinet users prefer to choose the capacitive screen touch mode. At the same time, in the aspect of capacitive touch screen, the anti-interference performance of Touch Think is recognized and trusted by users, and it can operate well in the power cabinet with strong electrostatic interference. Compared with the general capacitive touch screen on the market, it has a more competitive advantage.
