One of the sharpest cities in the American Southeast has received a dramatic digital makeover in recent years and the new look is delivering welcome buzz to a community striving to assert itself as a hub of commerce and innovation. Welcome to Charlotte, North Carolina.
In attempting to digitally recreate real life on a screen, one of the most important metrics to consider is contrast ratio, which the National American Standards Institute lays out as “the absolute difference in luminance between the peak white and black levels” of a display. While resolution, pixel pitch, and color space receive more attention from digital display customers and manufacturers alike, overall picture quality might actually be more dependent on contrast ratio. The reason contrast ratio is such a crucial determinant in image quality is because distinct elements of an image only stand out relative to their surroundings. If a display is unable to accurately differentiate the brightness of those surroundings from the brightness of the distinct image element in question, the resulting on-screen picture will fail to resemble true life.
There are two ways to measure the space between pixels and each tell their own story. The first is pixel pitch, a common specification listed early in the description of any digital display product. The second is fill ratio, the less common of the two metrics and one that only you’ll find listed much lower on any given spec sheet. Understanding the difference between these two specifications is crucial to identifying which display is best for your needs.
LED, LCD, ULED, OLED, HDR, DLP, AV. This alphabet soup can get confusing if you aren’t immersed in the terminology on a day to day basis and one of the most common mix ups occurs with the phrases LED and OLED. Let’s clear up some of this confusion by asking and answering some questions about these evolving display types.
Taking place next Thursday at 1 PM, what this webinar ultimately promises is that participants will depart with the knowledge they need to design the direct view LED vision that’s always lived in their head.
We would like to once again explore another slightly technical subject that readers would do well to understand: bit depth. While most people involved in the digital display industry have at least a cursory understanding of the effects of bit depth, many may not fully grasp how it works.
You may have missed it but the CEDIA 2019 show took place earlier this month, bringing together thousands of home technology professionals and hundreds of exhibitors for a weeklong expo. For those unable to make the trip out to Denver for this year’s show, I’d like to share a few of my takeaways from what proved to be a thought-provoking experience.
Displays are designed to communicate something, be that a message, an emotion, or a call to action but if your display is down, what you communicate is failure, regardless of the angle from which an audience can see it.
Light emitting diodes do exactly what their name implies; they emit light. But how? And why? If you’re interested in diving into the world of LED, answering these questions is a natural starting place. So let’s geek out for a bit by exploring the process of electroluminescence! (Don’t worry, we won’t get too technical.)
