In the past two years, the continuous shrinking of LCD splicing screens and the rapid rise of small-pitch LED displays have challenged the market application status of DLP seamless splicing screens. It has become an indisputable fact that application market share has been eroded. Suddenly, the decline of DLP seamless splicing screens became widespread. So, has the DLP seamless splicing screen really reached the “place where heroes are useless”? The answer is of course no. In the high-end large-screen display market that focuses on image quality, DLP seamless splicing screens are still the mainstream. Take the power industry as an example. Driven by the tide of social informatization, the construction of power informatization continues to accelerate-with the help of informatization means, the unified management of specialized functions such as grid dispatching, operation mode, relay protection, and communication can be realized. This means that in actual operation, the power dispatch center needs to monitor and monitor all the data, environmental parameters, and images of each substation, understand the situation of each station in real time, and be able to respond to emergencies in a timely manner. With a huge and complex power supply line, if you want to ensure the accuracy of monitoring information, a fine screen display will naturally become a guarantee. DLP seamless splicing screen not only has the unique advantage of “zero” stitching, it guarantees the exquisiteness of the display screen, but also can display static images for a long time to meet the continuous monitoring needs of

[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
