Antiglare vs. Antireflection

"Two terms used to talk about the impact of ambient lighting on displays are reflection and glare. The reduction of these is done using surface treatments for the display which are termed antireflection and antiglare. Because these are often confused, communications between display users and display engineers are often less than optimum. In this monograph, we will attempt to provide some guidance in usage."

Why The Digital Signage Industry Will Grow In 2013

As I peek at 2013 coming just around the corner, I cannot help but notice how downward price pressures are intersecting with demand and driving digital signage market growth. As many benefits continue to be realized, I believe some are more important than others and point to what we can expect in the coming year.

As in any tech-fueled market, reducing cost while increasing efficiency are major factors that come into play when talking about market growth. This fact is highlighted by realizing that digital signage fits well into the corporate mantra of “doing more with less.”

With digital signage, doing more with less is certainly one of the big benefits. And with noticeable price reductions in 2012 that are certain to continue in 2013, I concur with recent reports from IHS iSuppli, Platt Retail Institute and others who believe the demand will continue to build at a healthy pace.

Changes in Flat panel display EU import duty charges

Currently on import into the EU there are two duty rates that can be applied to flat panel display monitors - Zero or 14% depending on whether they are ADP (Automatic Data Processing) or Video monitors. Following a decision made by the WTO (World Trade Organisation) two years ago and the ECJ (European Court of Justice) the EU has had to consider changing its policy on these products. There is currently divergent practice among the Member States on the classification of monitors and the Commission has finally announced that from April 2013 the WTO and ECJ decisions will be implemented by a tariff suspension so will not be retrospective. If any of your members are currently paying duty on such products and need any assistance please contact us. My website is:

Is transparent ITO coating being used in new touchcode technology? (LinkedIn Discussion)

Michael Flynn
Unlikely. From their website: "The Touchcode will not be visible to the end user since it will be hidden under a layer of color or between paper (for example in a folded package)." If they used a transparent material there would be no need to hide it.

Walied Khan
Thanks Michael. That is precisely the point. My understanding is the Touccode itself works only with Projective capacitive displays. If it works based on the projective capacitive principle then there might be some embeded capacitance in the Touchcode tag/label etc itself. ITO makes for a good candidate. follow the link below for some additional info.

Anorexic Display Devices (Guest Post)

This opinion was contributed by Norman Hairston, a consultant to the display industry. You may find his blog at

"You can never be too rich or too thin.”

Attributed to Wallis Simpson (1896-1986) Wife of Edward, Duke of Windsor, formerly King Edward VIII

Thinness is a distinct advantage when it means reduction of layers and consolidation, especially in the display. The new in-cell touch screens in the iPhone take out a layer. Every layer in a display adds two surfaces and each surface can usually be counted on to contribute 4% in surface reflections that reduce sunlight viewability and image contrast in general. Much of the visual improvement from the iPhone 4 to the iPhone 5 can be attributed to this feature.

I've seen several studies that say that, for notebooks, consumers care a lot about weight but care much less about thickness as long as it is below one inch. Although the MacBook Air was greeted with great fanfare, the high price tag and lack of optical drive for that point in time lead to disappointing sales. Ultrabooks have likewise met a similar response. I've not seen similar data for cell phones, but I imagine that there is a similar threshold where consumers care much less about incremental thickness reduction. However, thin devices are much harder to engineer, so those companies with the most advanced technology like to promote thinness in order to advance their competitive advantage.

There are no inherent disadvantages to being ever thinner but sometimes the things that are done to make devices thin are inherently unhealthy for the device. The anodized aluminum casing for the new iPhone® is undoubtedly there to enable an incremental reduction in thickness. But the scratching issue that has emerged should have been anticipated given the nature of the material. Though the maker took great pains to protect the optics of the device with a Gorilla Glass® layer over the screen and a sapphire window over the camera lens, the pareto for protecting the cosmetics from scratching must have fallen below the priority for thinness.

Today AU Optronics Corp. ("AUO" or the "Company") (TAIEX: 2409; NYSE: AUO) signed patent cross license agreements with E-Ink Holdings ("E-Ink") and Hydis Technologies Co., Ltd. ("Hydis"), E-Ink's South Korean subsidiary, respectively. The parties have agreed to cross license specified patents owned by each party.

LENEXA, Kan. (October 15, 2012) – Keywest Technology threw down the gauntlet by needing to realistically illustrate dynamic digital signage content without mockup or simulation for its ever-expanding digital signage portfolio. To accomplish this, the company’s management called upon its creative chief, Brian Bibler, to build playlists that illustrate the company’s diverse digital signage portfolio and to do it in such a way that its dynamic nature could easily be viewed by anyone, anywhere.

According to company president Nick Nichols, illustrating the dynamic nature of digital signage is easier said than done when creating a portfolio that people can easily view from around the world. The company grappled with the fact that screenshots don’t quite capture the essence of digital signage media.

Keywest Technology Releases Videos Explaining The ABCs of Managing Digital Signage

Keywest Technology just released three videos in a growing series that explain the sometimes-mysterious operation of digital signage management. Presented in a conversational style that is akin to the company's popular weekly Webinar, the videos present a clear, logical explanation of the process that creates speedy workflow for digital signage management.

Digital Signage Application: Summer Lull Offers Opportunity to Evaluate Emergency Communications Plans

Changes to the nation’s emergency communications infrastructure offer authorities a way to reach out to people on their cell phones, but digital signs remains a vitally important part of the mix.

Summer is the time for fun, sun and relaxation. It’s also a good time to pause and think for a moment about the emergency messaging system your company, school, governmental agency or institution has set up to warn workers and visitors of possible danger.

Why contemplate trouble during such a carefree season? Simple, the summer lull gives many people a bit of a break from the volume of work they deal with the rest of the year.  Emergency messaging needs also become top of mind simply because of the number of severe thunderstorms and tornados that strike during the summer.

This summer in particular is a great time to reevaluate emergency messaging because of the work being done by the government and industries, such as the wireless and broadcast industries, to modernize the Emergency Alert System so agencies like National Weather Service and even state governors and the President of the United States can reach out to individuals’ cell phones and other mobile receivers to deliver vital information in a crisis.

Digital Signage Viewpoint: Is the Sun Rising or Setting on LCD Display Sales?

A new report from NPD DisplaySearch finds a sequential quarterly decline in flat panel LCD displays that are commonly used in public display applications, but the popularity of the same panels among consumers means the falloff in shipments isn’t necessarily bad news for digital signage.

Global shipments of flat panel LCD displays used for digital signage and other public display applications declined in the fourth quarter of 2011, marking the first sequential quarterly decline in three years, according to recently released data from NPD DisplaySearch, a global research and consulting firm specializing in the display supply chain.

The decline comes after a two-year period of impressive growth for the public display (also called the “large flat panel display”) category. Between 2009 and 2011, this market segment witnessed 65 percent growth in unit volume production, the display market research and analysis firm said.

The data, part of the “NPD DisplaySearch Quarterly FPD Public Display Shipment and Forecast Report,” show LCD display shipments were pulled down by a dropped in the 26-inch to 37-inch category. 

The decline raises an obvious question: “Is the public display market in general, and digital signage market in particular, sliding back into recession?” The answer, however, is far less clear.
