LCD screen will be widely used in many electronic products, one thing has been widely welcomed, and you will want to solve some problems, and pay attention to some things, let’s talk about how to pay attention to the anti-static problem of LCD screen? Electrostatic adsorption of dust reduces the insulation resistance of components and shortens the service life; Electrostatic discharge (ESD) damage, resulting in electronic components cannot work; the electromagnetic field produced by electrostatic discharge has a large amplitude and a wide frequency spectrum. Such electrostatic noise and electromagnetic interference make electronic equipment unable to work normally or even damaged.   Pay attention to:   The wristband should keep the body and the ground equipotential. ESD protection workbench should keep equipotential between device and ground. It is not allowed to place electrostatic insulating materials in the safe area .The circuit board with IC must be handled on the antistatic workbench. Wristbands and shoe covers should be tested every day to ensure that they meet the parameter requirements.   All instruments and equipment shall be grounded. Regard all components as electrostatic sensitive devices. Never touch sensitive devices or components without good grounding.   In the absence of other anti-static measures, do not take the IC installed in the anti-static tube. Use fixed-point ion eliminator in the process that may generate static electricity. If the IC is not on the process line or anti-static workbench, store them in a container with grounding shield. The gas and liquid flowing through IC should

With the popularization of the construction of national smart cities and safe cities, LCD splicing screens, as the best terminal display equipment, are favored by various industries and are perfectly integrated into our lives; as we all know, the LCD splicing industry is a sunrise industry with broad development. The prospects and entry barriers are extremely low. Therefore, the LCD splicing market has attracted an influx of many manufacturers, and the actual products of manufacturers are uneven. The viewing angle of the LCD splicing screen can reach 178 degrees, while the ordinary LCD can only see the 178-degree blank space. This is a very important criterion for distinguishing LCD splicing screens and LCD monitors. There is also the difference between the input signals of the two. The splicing screen is mainly the input video signal. In order to meet the interface requirements of different front-end devices, the splicing screen interface will be much richer than the display, including BNC, VGA, RGB, HDMI, DVI, S A variety of interfaces such as terminals meet the input requirements of different signals, while the monitor mainly inputs VGA signals, and the interfaces are mainly VGA, S-terminal, etc., which cannot meet the signal input requirements of various monitoring equipment. What is the difference between an LCD splicing screen and an LCD monitor, be sure to read it clearly when buying The driving scheme of LCD splicing screen is different, that is, the display motherboard scheme is different. Since the LCD display usually takes no more

The display screen can be divided into three types: normal temperature, wide temperature, and ultra-wide temperature according to the supported working temperature range. The normal temperature display supports the working temperature between 0 °C and 50 °C, and the wide temperature display supports the working temperature between -20 °C and +70 °C. ℃, the ultra-wide temperature display supports the working temperature between -40℃～+90℃. Usually, the display screen with good low-temperature performance will have poor high-temperature performance. The wider the operating temperature range, the higher the price. Users can choose suitable display products according to actual use conditions.
