From the demand of the commercial display market, LCD splicing screens are subject to more competition in the fields of education, security, engineering, digital signage, etc. Therefore, while the technology is highlighted, the LCD display is meticulously crafted and can break the small The size of the application is limited, focusing on the LCD splicing display products to achieve a “seamless” display effect in the splicing gap, as well as the further large-scale and diversified size, and the technical experience of high-definition highlight display. The LCD splicing screen is composed of multiple unit screens. Each splicing unit has a long life and low radiation to support its stable performance to support it. Different processing systems can be selected according to the user’s requirements for input signals. Supported by the application of emerging technologies, it can smoothly access massive signal sources and receive remote signals, which is conducive to the free switching of various signals through the control software, splicing into full-screen display, arbitrary combination display, image roaming and superimposing display, etc. , Such as can make it fully cope with the multi-faceted display system application of remote data roaming monitoring in the security field. It is enough to witness that such an ultra-high application solution can create personalized use for users on different occasions, and meet the needs of big data computing in the new era! The application of LCD splicing screen display is based on its excellent advantages in terms of diversified display methods and carrying massive signal reception

[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.

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
