LEDs have become a
mainstay of the human experience, so it’s astonishing to think the first light
emitting diode was invented by a GE employee only a little over 50 years ago.
From that first invention, the potential was immediately evident, as LEDs were
small, durable, bright and consumed less energy than traditional incandescent
LED technology continues
to evolve, pushing the boundaries of exactly where and how a display can be placed
and used. There are virtually no limits, as screens can now go just about
Changing Display Industry: Miniaturization and Ultra-Thin Screens
As the LED industry has
matured, it certainly has not slowed down when it comes to innovation. One
amazing advancement is the miniaturization of the technology, helping to
decrease the size and weight of the parts needed to build an LED screen.
Additionally, it has enabled the screens to become ultra-thin and grow to
monster sizes, allowing screens to rest on any surface, inside or outside.
Along with miniaturization
of technology, Mini LEDs are also informing the sceen of the future. Mini LEDs
refer to LED units smaller than 100 micrometers. Each pixel is individually
enable to emit light; it’s an improved version of the traditional LED backlight.
This new technology supports a more robust screen with super fine pixel pitch.
Advancements Are Changing the Future of LEDs
From sports venues to
retail stores to corporate environments, the applications for LEDs have multiplied,
much in part to technological advancements, including enhanced resolution, greater
brightness capabilities, product versatility, hardened surface LEDs, and micro
Pixel pitch is the
standard measurement to indicate resolution in LEDs. A smaller pixel pitch signifies
higher resolution. Resolutions started out very low, but now 4K screens, which
have a horizontal pixel count of 4,096, are becoming the norm. As manufacturers
work to perfect resolution, creating 8K screens and beyond are becoming more
and more promising.
LEDs emit a bright clear
light in millions of colors. When they work together, they provide alluring
displays viewable at very wide angles. LEDs now have the highest brightness of
any display. This means LED screens can compete well with direct sunlight,
allowing for clever new ways to use screens outdoors and in windows.
LEDs are extremely
versatile. One thing many engineers have spent considerable time on is
constructing the optimal outdoor screen. Exterior screens face significant
challenges including temperature swings, humidity, coastal air, and extreme
dryness. Modern LEDs can handle just about anything that the weather brings. And
because LEDs are glare-free, they are a perfect fit for many environments—from
a stadium to a storefront to a broadcast set.
Hardened Surface LEDs
LEDs need to be robust to handle any situation, so manufacturers are now working with a process called Chip On Board (COB). With COB, the LEDs are attached right to the printed circuit board instead of being prepackaged (when the LED is wired, bonded, and encapsulated for protection as individual units). This means more LEDs will fit in the same footprint. These hardened displays allow designers and architects to consider LEDs as an alternative to traditional surfaces such as tile and stone. Instead of one surface, these LEDs could allow for one that changes on demand.
Engineers have developed a
smaller LED—the microLED—and have included more of them onto the same surface.
Micro LEDs are moving technology forward, linking LEDs and images produced on
the screen. Since micro LEDs shrink the size of LEDs significantly, more diodes
can be part of the screen. This improves resolving power and the ability to
render incredible detail.
Large, High-Resolution LEDs
PixelFLEX offers industry-leading
LED display technology and solutions that transform spaces, creating immersive,
engaging experiences with large, high-resolution LEDs in a number of well-known
NETAPP utilized our FLEXMod LED display technology to create a one of a kind trapezoidal and curved display in its new Data visionary center that opened in 2018. This display showcases the companies commitment to technology and being a top tier provider in Silicon Valley.
On the Las Vegas Strip,
you’ll find Beer Park, the first rooftop bar and grill at the
Paris Las Vegas Hotel and Casino. The focal point of the space is a sub 2mm LED
display above the center bar and allows for either multi or single views.
Hino Trucks, the commercial arm of Toyota trucks implemented three fine pixel pitch display in its new Detroit HQ to showcase its diagnostic technology as well as create a one of a kind employee theater for meeting and events.
