What is the lifespan of an industrial tablet computer?
Everyone knows that industrial tablet computers are used in industrial environments, and some environments are poor, so how to ensure the service life of industrial tablet computers? We often encounter customers inquiring about the lifespan of industrial tablet computers. Today we will Let's have a systematic understanding.

First, let's talk about the structural issues of industrial tablet computers. In terms of hardware, there is not much difference from ordinary computers. They are all composed of motherboard, CPU, hard disk, memory, graphics card, display screen, etc. However, industrial panel computers are generally used in relatively harsh industrial environments in applications, and the required hardware is more stringent than ordinary hardware.
In particular, industrial-grade motherboards are used on the motherboard, a fanless cooling system and a sturdy aluminum alloy chassis are integrated. Regarding the specific structure of industrial tablet computers, you can click to view for more details.
Touch screens are generally capacitive touch and resistive touch. These two touch screens are like printing consumables, and they will disappear after a long time. During the use of the touch screen, the resistive touch realizes the operation and control of the screen content through the principle of pressure sensing. The multi-layer composite film with the resistive touch screen, the conductive layer and the glass layer sensor on the surface of the multi-fat The current separated by the interlayer passes through the surface layer, touches the surface layer pressure, and touches the bottom layer. The controller simultaneously reads the corresponding current from the four corners and calculates the distance of the finger position. Can form precise touch positioning.
The working principle of the capacitive touch screen is to paste a layer of transparent special metal conductive material on the glass surface. When a finger touches the metal layer, the capacitance of the contact will change, causing the frequency of the oscillator connected to it to change. By measuring the frequency change, the touch position can be determined to obtain information. Since the capacitance varies with temperature, humidity, or grounding conditions, its stability is poor and it tends to drift.
It can be seen that the life of an industrial tablet computer is determined by many factors. In order to ensure the life of the product, in addition to standard operation, it is also necessary to modify the equipment.
