If you're planning to update your digital signage it's a good time take a look at the new OLED (organic light-emitting diode) technology that's revolutionizing the appearance and clarity of large displays.
Here's what you need to know about OLED signs:
How OLED displays are different
A carbon film is placed behind the glass screen on an OLED display, which is where the "organic" designation originates. Unlike standard LED/LCD displays, which require a back light to operate and indiscriminately brighten both dark and bright spots on a display, OLED panels don't need a backlight as they emit light themselves. This eliminates the screen washout that occurs from the back light illuminating black and dark areas.
In standard LED systems, they have tried to cut lights on diodes behind black and dark areas to increase contrast and create more vivid displays. However, the lights did not perfectly align with the pixels and led to bleed over from dark to light areas. OLED systems allow each pixel of a display image to be lit or blackened. There's no bleed or washout, so colors are more lush and contrast is incredibly sharp.
Other benefits of OLED
OLED displays can be curved or presented in a wavy form to attract attention and add visual interest. The displays are also very thin with a modern, low-profile aesthetic that will easily coordinate with any environment or decor. At only a few millimeters thick, the displays weigh far less than traditional backlit LED TVs, making them safer and easier to hang in areas where people walk or congregate close to signs.
OLED displays also have a very low refresh rate that's 1,000 times faster than standard LED displays. The colors pop and the black sections are rich and deep, while the action on screen flows smoothly to create stunning images, animation and program flow. The OLED components are actually transparent, too, so it's possible to make see-through signage displays that integrate with their surroundings.
OLED signage is becoming more affordable
Like OLED televisions, which have been on the market since 2012, OLED signage is becoming more affordable as the technology is being refined. But OLED signage is not a budget choice at this time. Look for lower signage prices as more companies adopt the technology and begin producing OLED products.
At InfoComm 2016 in Las Vegas, there were several OLED displays on hand, showing off their ultra-HD 4K quality and high performance. One great thing about the displays is their internal memory capacity, which allows them to continue to play content with no PC or other media device attached.
Digital signage is the business-message format of the future. OLED takes digital signage to another level of beauty and practicality. For further assistance, contact a local sign manufacturer.Share
