1. Magnetization of industrial displays: Partial areas of industrial displays have color casts or light spots. This is because there is a large alternating magnetic field in the environment where industrial displays are located. Look for high-power electrical appliances, such as high-power transformers, speakers and other equipment nearby, and move them away. Use the degaussing function of the industrial display itself to degauss the industrial display. Change the orientation of industrial displays to reduce the influence of geomagnetism on industrial displays.
Second, industrial display color cast: all areas of the industrial display have color cast, which is caused by the deviation of the color setting of the display or the color setting of the graphics card, and the signal line plug of the industrial display has poor contact with the graphics card of the host. Use the color function settings of the industrial display itself to adjust the color settings and adjust the color settings of the graphics card; fix the signal cable plug of the industrial display and the graphics card to each other to ensure that the display signal line is in full contact with the host graphics card.
Three. No display on the industrial display: The industrial display has a black screen without any image. There are many reasons for this phenomenon, which are explained below:
1. The industrial display circuit is faulty.
2, the industrial host is faulty.
3. The power input of the industrial display is faulty.
4. The signal line of the industrial display is in poor contact with the host display card.
The solutions to the above faults are as follows:
1. Check whether the industrial host is working normally.
2. Check whether the signal light on the front of the industrial display is on. If not, check whether the power cord of the industrial display is in normal contact with the display.
3. If the fault still cannot be solved, please find a professional for repair in time or contact the manufacturer of the purchased product to solve it.
