With LCD technology with an LED backlight dominating indoor signage applications, such as video walls, it has been increasingly difficult for other technologies, such as high-resolution LED to gain a foothold in this market. However, this may be changing, and changing fast…
While LED has traditionally played catch-up with LCD displays, the former are now available in tiled or modular formats under 2mm and offer compelling images – even up close. So, are you prepared to bet on evolving LED technology replacing LCD technology for indoor signage, such as video wall displays? Read on…
Increasingly, high resolution LED flat panels with interactive capabilities are vying to compete with existing LCD technology. However, price, performance, and fit for the application, will determine which technology wins.
The following points should be kept in mind when determining whether LED is right for your organisation, as compared with LCD:
LED modules with 1.9 mm, 1.6 mm and even 1.2 mm are available from a number of sources. Prototypes of modules at 0.8 mm have been shown and roadmaps suggest 0.5 mm is feasible within the year
LED displays have pixel pitchs in the same range as a FHD resolution LCD display panel at 70 to 90 inches. However, thin bezel LCD panels are headed toward UHD resolution over the next year or so
Viewing angles are probably better with LEDs
Currently, the color gamut of an LED display varies from manufacturer to manufacturer. Top tier suppliers have a very controlled binning process that helps assure colour uniformity across the display. However, LCDs are easier to colour calibrate, which ensures that the display on your video wall has the exact colours that your advertisers want to see
Fine pitch LED solutions are much more expensive than an LCD solution, even if the latter has UHD panels
Applications that are choosing to go with LED technology include:
1. Curved walls used for indoor video displays
2. Broadcast media, as on-camera background displays, because of their colour temperature, tuneability, and variable luminance capabilities.
3. Displays where a zero bezel look is desired
So, now you know whether and when to opt for an LED display over your more widely-used LCD display. The upcoming Display Summit on June 15 and 16, 2015 at the InfoComm show in Orlando, Florida, in the United States, will demonstrate both LED and LCD technology-driven displays.
This will help many businesses, such as yours, determine whether LED displays for indoor signage solutions, such as video walls, are right for them. Here’s to an attractive, convenient, and high-quality video wall experience…
