Regarding the visual effect marketing of LCD advertising machines, I think all businesses are concerned about how to use LCD advertising mechanisms to make more attractive video content. If the LCD advertising machine does not have any video, just the combination of pictures and text, then it is like that people have no language but only action, and life will be boring without any color at all. The same is true of LCD advertising machines, lacking what is needed to effectively convey information. Dimensions, attractiveness and vitality. Whether you want to attract customers’ attention to the screen content or convey important information, video is more persuasive and attractive than text or static images. How to use the LCD advertising machine to achieve better results The simple explanation is that the video can better express the information to be conveyed, and it is also an effective and direct way to get the audience’s attention. According to a study, 100 people choose a comic and a video, and 85% of them will choose to watch the video. After understanding this, it is much more convenient to use the video marketing of the LCD advertising machine. Merchants can choose to use video marketing to stimulate potential customers when there is a lot of traffic, attract customers’ attention, and leave customers with a clear and unforgettable impression. When potential customers are curious about the video, they will naturally interact with the LCD advertising machine. During the process of interacting with the LCD advertising machine,

LCD brightness Brightness represents the amount of brightness of a picture per unit area. Specifically, the density of the amount of light passing through the normal direction of the screen. The unit is [CD / m2] or nit（1 nit = CD / m2).Brightness depends on the amount of light passing through the LCD and color film, and the brightness of the backlight.   LCD backlight requirements: The liquid crystal should have good transmittance; light weight; It should be thin and not easy to damage; The area light source with uniform brightness is the best; Low cost; The light color is pleasing to the eye, the primary color is rich, and the brightness can be adjusted; Low power consumption and easy power supply

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
