Six characteristics of digital signage welcomed by the market

With the increasing development of commerce and consumption, the demand for digital signage is also increasing. With its networked, digitized, and informatized multimedia digital signage, it has become a bright spot in the advertising media market. Furthermore, from the point of view of the application fields and functional uses of digital signage, it has gradually been integrated into all aspects of people’s life and work. The following editor  will reveal the 6 major characteristics of digital signage that are popular in the market: 1. The multi-media nature of digital signage Digital signage can spread a variety of media information. Information such as sound, text, images, etc. makes ignorant and uninteresting advertisements more vivid and humane. And can give full play to the creativity and initiative of the store. 2. The time domain of digital signage The ultimate goal of digital signage is to occupy the market share of advertising, and digital signage can surpass the constraints of time and space for advertising. However, most businesses will control the time period to play advertisements, effectively spreading the effectiveness of advertisements. 3. The technicality of digital signage Digital signage must have certain technical support to help merchants promote sales. It can change traditional concepts and enhance the needs of merchants and customers. For digital signage operations, video editing, computer technology, image processing and other compound talents, can they have a competitive advantage in the market. 4. Personalization of digital signage In the store, when the salesman sees the customer coming to the

Advantages of ultra-narrow LCD splicing screen

The ultra-narrow LCD splicing screen is based on pure hardware and adopts parallel high-speed graphics processing technology to realize the unified processing of multiple high-speed video signals, fundamentally replace the plug-in splicing controller, and solve the problem of limited VGA signal input. Clarity, brightness, and color saturation are three important performance indicators of liquid crystals. The ultra-narrow-edge LCD splicing unit has the characteristics of high definition, high brightness, and high color gamut. Because the LCD uses backlight tubes as the light source, the edges are generally wide. The 40-inch ordinary LCD screen has a margin width of more than 11mm. If used for splicing, the splicing gap should be at least 22mm, which will affect the visual effect. The LCD splicing wall adopts a liquid crystal screen with a narrow-edge structure design, and the edge is reduced by more than double, which does not affect the visual effect when used for splicing. The LCD splicing screen has ultra-narrow edges, the number of splicing can be selected arbitrarily (row (m) X column (n)), and the size of the screen also has a variety of options to meet the needs of different use occasions. The ultra-narrow edge of the LCD splicing screen can be customized according to the requirements of different users, and you can choose functions such as single-screen display, full-screen display, and arbitrary combination display. In view of the inconsistency of parameters between the LCD screen and the driving circuit of the LCD splicing screen, the Tianjin LCD splicing screen

How to prevent static electricity of LCD?

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
