In daily life, we must keep the habit of “cleaning” the LCD advertising machine regularly. You can spray it on the LCD advertising machine screen with a special potion, and then gently wipe it with a clean white cloth. Try not to use a damp cloth with too much water content. Too much water content on the damp cloth can easily cause water to stay on the screen. Water entering the screen through the edge can cause a short circuit in the system and the LCD advertising machine cannot work normally. It is recommended to use soft scrubbing materials such as glasses cloth and lens paper to scrub the screen to avoid unnecessary scratches on the LCD advertising machine screen. The working environment of the LCD advertising machine directly affects the operation and service life of the LCD advertising machine. If the working environment of the LCD advertising machine is too bright, or even direct sunlight, this will not only affect the visual communication of the LCD advertising machine, but also damage the LCD advertising Machine screen electronic components. The air humidity of the working environment where the LCD advertising machine is located must be kept suitable, and two extremes must not be taken. Once the electronic equipment is too humid, it will only affect the circuit conditions and cause the LCD advertising machine to fail to work normally. No matter how good electronic products are, they will have their own longest operating time, and LCD advertising machines are no

This video showcases two different types of glass used in outdoor machines: tempered glass and AR laminated glass. Both types were subjected to impact testing and smashed to demonstrate their differences.Firstly, let’s take a look at tempered glass. While it’s stronger than regular glass, it can still shatter under strong impact. When tempered glass breaks, it splits into small pieces that may cause harm to people nearby. By contrast, AR laminated glass offers superior safety performance. It uses a polymer interlayer to bond two sheets of glass together, which ensures that even if it breaks, the glass fragments adhere tightly to the polymer. This means shattered glass won’t fly around and is easier to clean up. As a result, AR laminated glass is widely used in situations where high safety is required, such as car windows and building exteriors. Through this test, we demonstrated how the two types of glass break differently. We hope this video provides useful information to help you better understand different types of glass. https://youtu.be/60wnYg0ubzs

[Fault Phenomenon] One LCD touch screen doesn’t work, and there is no response when touching any part.   [Fault Analysis and Treatment] First check whether the connection interface is loose, and then check whether there is conflict between serial ports and interrupt number. If there is conflict, adjust resources to avoid conflict. Then check whether there are cracks on the surface of the touch screen. If there are cracks, replace them in time, Also need to check whether there is dirt on the touch screen surface, if there is, use a soft cloth to remove it. Observe and check whether the indicator light on the control box works normally. When it works normally, the indicator light is green and flashes.   If the above parts are normal, the touch screen can be checked by replacement method, first replace the control box, then replace the touch screen, and finally replace the host.   If it is a resistive touch screen, it can be overhauled as follows: 1）Check whether the connection of the touch screen is right, and whether one of the connections (taking 5V touch screen working voltage from the keyboard port) is connected. Please check the connection. 2）Observe the light condition of the touch screen control box. If it doesn’t light up or the red light is on, the control box is broken. Please replace it. 3）If not, please delete the touch screen driver and restart the computer, re-install the driver, or replace the driver with a newer version. 4）If
