Think Your Space Is Too Bright for Large Format Digital Signage?


Then it’s time to outshine the sun.

It’s a common concern in places such as airport concourses that are bathed in high ambient daylight. Will large format LCD digital signage be able to deliver crisp, vivid images amid all that brightness?

With the right technology the answer is yes. LG’s Shine Out technology is a well-suited solution for delivering crisp, clear and vivid 4K UHD content in areas with direct sunlight, bright ambient light or harsh indoor lighting.

When displays are placed in front lobby areas or window-facing applications where there might be a lot of sun, the harsh reflection and glare can wash out even the best images. To preserve image quality, Shine Out technology features an anti-glare, anti-reflective overlay that does not soften the image like conventional anti-reflective coatings. Instead, it actually increases contrast ratio and color saturation while deflecting the light. The overlay also protects the screen surface, which is very important in a public environment where people can get close to the screen and bump into it, scratch it or hit it with an object.

And when you factor in the displays’ advanced local dimming function, the image quality maintains high contrast so colors pop. With LG large format 4K UHD displays, the backlighting in specific areas of the screen can be controlled to increase contrast and provide a clearer image. LEDs that can be switched on and off are installed behind the screen’s liquid crystal pixels. This means that a specific area on the screen that is displaying black can be darkened even further, by switching off the LEDs separately from brighter areas where the LEDs are switched on. The result is reduced light leakage, substantially deeper blacks and excellent contrast.

To top it all off, LG’s IPS (In-Plane Switching) screen technology provides true wide viewing angles up to 178 degrees, where colors and contrast remain consistent and data is clearly readable. With non-IPS displays the viewer needs to be centered directly in front of the screen to realize the best performance – at an angle color and contrast decrease dramatically and data becomes illegible. IPS vastly improves off-angle viewing, which is extremely important in areas with heavy foot traffic. IPS panels also feature effective thermal management that eliminates image degradation and screen blackening that can occur with non-IPS displays placed in direct sunlight.

Large format 4K UHD displays are ideal for attracting attention and making the message matter. And with Shine Out, advanced local dimming and IPS they can cut through the brightness with a brilliance all their own.


Video Walls Slim Down and Lighten Up to Reduce Costs


Blog081018_880x440In 2018, the best video wall systems are made up of advanced flat panels that are lighter in weight, and less deep in profile than what was common not too long ago.

If your video wall/flat panel supplier is not offering options that are light in weight (44 lbs. or 20KG), and slim in depth (3.42 inches or 87 mm) to allow for easier installation and easier maintenance of the displays after installa­tion, you’re using yesterday’s technology.

It’s important to note that if a video wall is mounted in such a way that it protrudes more than four inches from a wall at foot-traffic level, then it is not compliant with strict ADA (Americans with Disabilities Act) regula­tions. For this reason video walls are often set back into the wall itself, to accommodate the mounting gear, cables and other hardware, and maintain ADA compliance.

Remember also that weight considerations affect many aspects of a video wall installation: shipping costs to get the product to the site; the amount and cost of mounting hardware needed; the number of handlers required per panel installation, and maintenance costs after the installation is complete.

Whether upgrading from older video wall technology or revitalizing your business environment with a first-time video wall, be sure to choose a video wall/display supplier that is at the fore­front in light weight, thin dis­plays and integrated mount­ing systems.


Calibrating Video Wall Screens for Picture Perfection


Video wall calibration may sound daunting to end users and even to systems inte­grators frustrated with working with identical displays from the same manufacturer that look dif­ferent while showing exactly the same content. It all boils down to this: a video wall is by definition a configuration of individual images. So the different displays that make up a video wall must be calibrated to show a uniform picture across the entire wall.

This means not only maintaining brightness uniformi­ty across the screens, but also keeping the edges of each display as bright as the center of each display, and keeping the color consistent across all displays. In digital imaging, there is nothing as off-putting as a video wall that includes a scene of a beautiful blue sky but has one off-color greenish display right in the middle that spoils the effect.

The solution is to choose a video wall display provider that provides reli­able factory calibration (each display in a video wall design is set up at the factory to be calibrated with its sister displays in that video wall design). But there’s another important step.

Due to environ­mental factors, third-party content software anomalies, and user error, there often needs to be some calibra­tion on-site at a video wall installation. So the video wall display provider must also provide a fast, easy-to-use on-site calibration system.

Ideally this will include an Automatic ID setting for easy installation, so that if you install 100 displays, you do not need to waste valuable time setting up the unique ID of each one respectively. The Automatic ID eliminates the frustration.

To address the challenges of matching brightness and color across all screens, LG video wall displays incorporate factory calibration as well as efficient calibration tools, including an Automatic ID setting that allows for easy installation – integrators can achieve an optimal image within only 3-5 minutes per panel.

A video wall is a significant investment. And as such it should be expected to provide a breathtaking and realistic image to wow viewers, seriously engage them and make your message matter. Make sure your video wall is up for the task.
