Every medium used to convey information needs engaging content. Digital signage is no different. From the words used to the font chosen, digital signage has certain nuances and size constrictions that need be considered in order to successfully reach the target audience. For reference, we've compiled the eight most important things to remember when creating and managing digital signage content.   1. Keep text simple and clear. Consider using black-and-white text for optimal legibility and include color through images and headlines. It's best to stick with dark text on a light background or visa-versa to ensure plenty of contrast on the screen. It's always best to use sans-serif fonts on digital signage displays. There is a wide variety of fonts in this family, and bold or italic text can be used to highlight important phrases. Make sure text is legible up close and from a distance. We recommend 1-inch size in text for every 10 feet of distance from the screen. Avoid all caps. It's hard to read and can come across as aggressive.   2. Timing is everything — When using a slideshow-type screen with scrolling images, slow down the timing in order to allow the audience to consume the information. Often the screen frequency is too fast, leaving the viewer frustrated and unable to digest all of the content. However, leaving the screen for too long can be equally damaging to the message. We recommend keeping each item/screen play time under 7 seconds.   3. Use attention-grabbing visuals. Remember that the screen is silent, so text and images must be dynamic. If brand imagery is being used, keep brand-icon usage consistent with usage in other media. Keep brand colors running throughout the screens to keep brand recognition throughout the presentation.   4. Place a call to action on every screen — Start a call to action with a verb, keep the verb and subject close together, and embed it in each screen being used (e.g. "Get Yours Today," "Get Started Now," "Try it for Free," etc.)   5. Keep motion to a minimum — Use motion sparingly. Too much motion can have a detrimental effect on the message by distracting the viewer. When using motion, keep a logo or text box static as a grounding point on the screen. Motion on the periphery is more subtle than motion in the middle of the line of sight. The most important features should be static.   6. Content variety is critical — Digital signage content should vary greatly based on the location and intended use.    7. Content is king — Is the content entertaining, informing and educational? Consider using rhyme and alliteration to allow for quicker retention and memorization. Most people can remember up to three items at any given time. Keep the message clear and concise, and keep the screen views long enough so that the message can be read and absorbed.   8. Should content be managed remotely or manually? — Installing signage with remote management capabilities is one of the best ways to update content. Many digital signage companies have software that can include new social components for Digg, Instagram, Google Calendar, Google Drive, Picasa, Google Plus, YouTube, Facebook, and Twitter. In addition, some digital signage companies have added new integration features for web browsers and expanded support for node.js and JSON for custom insertion and custom component integration.

    In general now display market flowers bloom, colorful, really is to let a person too many things to see, dazzling. As business information network, intelligent, social. More and more middle-end factory using display products to brand promotion, differentiation marketing, collect or transmission of business information. Now in the domestic market the most large, joining together the fire has become the hottest LCD splicing screen, they are the best, most in need of a friend. But there are many clients non-traditional security industry professional customer, just know the product name, only stay on such a concept, instinctively think LCD splicing screen is pretty much the same.       LCD splicing screen with traditional LCD television screen is the biggest difference between industrial manufacturing. LCD TV for half of the family, and LCD splicing screen for industrial engineering. LCD TV work play continuously for 48 hours will fail, and liquid crystal splicing screen can play continuously for 365 days. Use ordinary LCD TV LCD liquid crystal screen the service life of the back light for 10000 to 30000 hours, and the service life of DDW LCD splicing screen back light can be up to 100000 hours, this ensures that every piece of the LCD panel used in the splice screen after long time using the brightness, contrast and color consistency, and ensure the service life of the screen not less than 50000 hours.     Liquid crystal splicing screen and liquid crystal TV is used as a display image signal, but the performance, structure of the two totally different. First LCD TV screen and liquid crystal splicing of display screen is not the same, a screen to the LCD splicing, to higher than LCD TV screen technology parameter. Made of liquid crystal screen plate LCD splicing screen play high brightness of the picture is different obviously, under the high brightness of the picture color, level obvious distortion. Another LCD splicing screen using parallel high-speed image processing technology, realized the unification of the multi-channel high speed video signal processing, fundamentally to replace the plug-in stitching controller, solve the problem of the VGA signal input quantity is limited.       LCD splicing screen it will with the most excellent high definition, high brightness and high color gamut of liquid crystal display technology, the embedded hardware splicing technology, multiple screen image processing technology, such as signal switching technology, forming the most advanced LCD splicing display system. LCD splicing wall is an entirely new way of large screen splicing, its indefinitely splicing.       Liquid crystal display technology after years of development, already has an important role in the field of liquid crystal splicing display. Splicing screen with lightweight, ultra-thin, low power consumption, no radiation, high-definition, long life and low maintenance cost advantages of prominent one. LCD splicing screen with LCD display as the basic unit, set the newest liquid crystal display technology and pure hardware high-speed real-time splicing control technology in one, all of the input signal is free to display in the window display wall, fully support across the screen image, roaming, picture in picture, superposition, scaling and other high-end display function.       DDW think its controller to display tailored, special plane, can maximum limit display unit efficiency into full play. LCD splicing screen image clarity, flexible combination, shows rich content, can give users the biggest free space design, provide the display effect of shock. And liquid crystal TV can only show half simple picture, although also came out some LCD TV on the market, but from the interface, types of signal, to distinguish is not equivalent to that of liquid crystal splicing screen.

Parsing the LCD splicing screen application in various fields   With the development of all walks of life, promotion of computer technology, as a liquid crystal splicing screen service providers have to improve, people on picture clarity and resolution, high brightness, high contrast are the pursuit of more perfect. The major demand for each big industry, let's grow up quickly, production and meet the demand of the market. As the change of demand, all kinds of large screen in different sectors have different advantages.     A variety of liquid crystal splicing screen series, LED backlight super bright screen, single, any combination, according to the display function, the built-in digital matrix, can need not matrix. Stitching a signal at the same time, we can also external matrix do more signal any stitching at the same time. This series is widely used on a large screen, involving multiple areas, can be used for security, command center display screen display, the entertainment industry, enterprise information display, advertising media, convention and exhibition center display, factories and mines, electric power, water conservancy, education, organizations, army and mine industry, etc. This large screen has a variety of installations, can be wall-mounted, embedded, floor cabinets, hoisting, TV ark, etc. This series of splicing screen can be set in a manual, timing, cruise, alarm plan and kaleidoscope demonstration, intelligent temperature control and alarm, communication malfunction automatically detect, and other functions, can be full screen, much separately display signal, the whole screen, display in any combination. LCD splicing screen is currently the most high-end, the most ideal display device, its superior performance, has won a wide recognition. A traffic monitoring center the joining together of curtain wall, for example, more of the time required to watch all images of point to point at the same time, the abnormal situation when a monitory point, can quickly zoom to full screen for all of the monitoring center to watch at the same time. This request in practical application, the splicing curtain wall in the big screen and small screen should be achieved good display effect. And size combination, use more flexible; Stable long service life, low maintenance cost. So many advantages, for the user unit, LCD splicing screen is the best choice.

        Liquid crystal splicing screen experience can bring you a better display effect, ultra wide Angle of view, the display of large capacity, in all aspects of life are better visual enjoyment. To ensure the smooth progress of the project equipment installation on site must meet the following conditions:       1. Install the environmental requirements   Installation ground smooth solid, strong bearing capacity, deformation, due to the liquid crystal splicing stent generally direct contact with the anti-static floor, need to make sure that the ground bearing stress deformation for a long time.   2, light requirements   Concealed lighting recommended canister light, the light shoulds not be pointed directly at the screen direction, distance from the screen to keep 3 metres away, lest affect the projection effect; Second should avoid direct sun light.   3, go line and trough   Low voltage cables (VGA video network serial mouse and keyboard extension cords, etc.) should be separated with high voltage cable line, to avoid interference. If it is to use go trough can't share a go trough, trough separate walk should be different.   4, power supply,   Considering the system may encounter special would happen breakpoint again electrify current shock, LCD splicing unit itself has power protection design, guaranteed the normal safe operation of equipment; System of power supply for AC 220 v + / - 5%; With a protective earthing line three eye socket, socket number related to splice screen number; Power supply voltage should be stable and reliable; System equipment should have good grounding, grounding resistance < 2 Ω, ensure encountered lightning strike and other special situation when the equipment is not damaged.   5, system environment,   1) time the good temperature and humidity control room requirements. Working environment temperature is 23 ℃ + / - 5 ℃, relative humidity 20% to 80%. Joining together back to have air conditioning.   2) before and after the splicing screen air-conditioning temperature and humidity should be transferred to the same scale, in order to ensure that splicing wall heat dissipation and splicing flatness of the screen.   3) splice screen for clean room, dustproof.   4) the fire sprinklers away from splicing wall as much as possible, and to use the spray fire extinguishing agent  

      In recent years, along with the advance of the LCD splicing technology, no matter from the seam in technology, or from the screen size, LCD splicing screen has been constantly enrich their own conditions for the various performance indicators, further promote the healthy development of the LCD splicing screen products on the market. Among them, the "big size" is the core of the LCD splicing screen, because big size LCD splicing unit in the splicing is greatly reduce the frame frequency, flat-fell seam on ensure image integrity superior greatly small size LCD splicing unit.   With large size LCD splicing screen in application to show more and more prominent, the LCD splicing manufacturers are also constantly develop larger LCD splicing screen. Now, the size of the LCD splicing unit is more and more big, the LCD splicing screen from 40 to 60 inches, and continues to expand more advantage of the large size LCD splicing screen. Large size LCD splicing screen LCD splicing TV wall as more and more applications in various fields, especially in some consultation with the system, the circuit diagram, such as cloud, accurate data shows that air systems, or scientific research units in areas such as widely used. Large size LCD splicing screen can get the favour of users, is the splicing unit in joining together to reduce the picture size large flat-fell seam in frequency, together with the application of various image processing technology, which makes the big LCD splicing presents a picture of integral feeling is stronger. Now although LCD splicing technology can realize super narrow edge flat-fell seam, can fully guarantee the integrity of the picture, but the LCD splicing screen flat-fell seam for high precision image display project is lack of something. And big size LCD splicing screen not only have a single display, it also has a higher brightness and color uniformity, at the same time, because of the large size of the audience watching the display screen will be more relaxed, more open perspective.   Throughout the current LCD screen splicing market, large size LCD splicing commercial time still has an upward trend, compared with these small size 32 inch, 40 inch LCD splicing unit, large size LCD splicing screen the most prominent advantage is that it can realize no flat-fell seam no physical aperture image, not only to ensure the full hd picture, also save some patchwork peripheral equipment. But large size LCD splicing screen also has its own shortcomings, that's not flexible size and the way of joining together. Large size LCD splicing screen often thorny problems is caused by a problem of power consumption and weight installation is not easy, so big size LCD splicing screen should further development need further improvement on the power consumption and weight. Nowadays, the overall development trend of LCD splicing system is to a large screen, high resolution, high brightness, high contrast and modular structure design and easy to install, manage, and control the direction of development. And single LCD splicing screen size will be more and more big, big size LCD splicing unit unit can be used independently as a display screen, also comparative advantages on the stitching. , in the development of the large size LCD splicing screen will keep a new Chen, let more users experience the charm of LCD splicing screen.
