1. The stability of the whole machine (including use time, anti-interference, etc.)
In the use of project engineering, LCD splicing screens usually need to meet 24 hours a day, 7×24 hours of continuous and uninterrupted power supply; and in some projects, the application environment of LCD splicing screens is relatively harsh, which requires LCD splicing screens to be more severe. High reliability and stability.
2. Important performance indicators of LCD splicing screen
mainly from the perspective of brightness, contrast, color saturation, service life, resolution, viewing angle, service life, etc., which can be determined according to different sizes of splicing screens. The brightness is generally 700cd/cm, the contrast ratio is 3000:1, the color saturation is 97%, it can work without interruption for 24 hours, and the viewing angle is 178 degrees.
Three, control interface
The LCD splicing screen can be controlled by S232 serial port, and there are more than 200 open control passwords, which can adapt to various industrial environments. When it is convenient to use multiple splicing screens, all display devices can be controlled without a remote controller, and it can assist various industry requirements such as timing start-up, delayed start-up, and machine self-inspection.
Four, fanless architecture
The LCD splicing screen is designed with no mechanical exhaust fan to maintain air circulation and heat dissipation, so as to avoid the dust and fan noise caused by the mechanical exhaust fan. When the internal temperature rises due to unknown reasons, the LCD splicing screen automatically controls the backlight system to reduce the temperature. Keep below the maximum operating temperature.
5: Look at the design of the LCD splicing screen
You need to look carefully, to see if the frame structure is not stable enough, if the overall structure is reasonable. Check the basics, detailed air pipes, and fixed mirrors. These cannot be ignored because they will affect the stability and life of the LCD splicing screen system.
