Are you looking at embracing the video wall solution? Deciding on the display type to use might be an issue you need to resolve before embarking on the project. Nowadays, there are many display technologies out there in the market with each one trying to make its footprint!
LCD and LED are two technologies that have positively made a mark in the display world. A comprehensive look at the features and benefits of these two technologies could be of great help to video wall buyers towards making a choice that best meets their need.
What is LCD, LED
LCD stands for Liquid Crystal Display, while LED means Light Emitting Diode display. Looking at it from a technical angle, it could be argued that LED display is an LCD as it is built on LCD technology with LED back-lighting.
The basic technology is the same in that both display types have two layers of polarized glass through which the liquid crystals both block and pass light. The two technologies both offer optimal connectivity to numerous external multimedia and gaming devices, as well as great picture and sound qualities.
Comparison between the two technologies
Since the emergence of LCD and LED displays, stakeholders have always tried to make case for which of the two technologies offers the finest performance and end-result for the best possible price.
While it might seem evident that the LED would be the obvious choice because it is newer technology, a huge number of consumers are still of the view that the LCD display offerings are best suitable to their specific needs.
Both LCD and LED displays require a light source to illuminate its pixels. This requirement results in the basic difference in their designs – the LCD technology relies on a set of fluorescent tubes for illumination, while for LED display, the tubes are replaced by an array of Light Emitting Diodes.
These light emitting diodes are more energy efficient when compared with the fluorescent tube option employed in the LCD design, but it may be useful to point out that the former makes up for this in its cost as LED displays are much more expensive than their LCD equivalents.
In addition, LED displays arguably have slightly better colour accuracy than their LCD counterparts. They take advantage of an inbuilt wheel of distinct RGB-coloured lights to produce more realistic and sharper color outputs. Though there is not much difference between the color accuracy of LED and LCD, it will be a disservice to the readers to deny that LED displays have great colour accuracy.
As far as both technologies are concerned, there is not much in between the maximum angle at which they can be viewed (that is, placing them side-by-side, their viewing angle feature is more or less the same). This will depend on the type of LCD panel used by the manufacturer and the type of glass mounted in front of the LCD panel. A thicker and higher quality glass panel should generally produce a better viewing angle.
Video wall Support
For video wall and digital signage solutions, the LCD display seems to be the preferred technology, as they are less susceptible to burn-in, an issue mostly associated with LED displays. Also, consumers who set up a high-end home theatre on their PC may also opt for LCD displays to avoid the same. However, for displays where a zero-bezel look is desired, LED is clearly the preferred option as they come in thinner bezels but the ultra-narrow bezel LCD design is now gaining more popularity for video walls and in great competition with LED displays because it creates the smallest seams.
While it might look as if LED displays have considerable gains over LCDs, the type of technology you choose eventually depends on your needs, applications, and budget. Price is mainly the biggest difference between these two technologies. LCD, which is now considered an older technology when compared with its LED counterpart, costs much cheaper than the LED. The overall effect of cost on technology boils down to the fact that the older the technology, the lower the price. Hence, newer technology carry higher price tag!
