LCD vs LED


LCD or LED

LED displays have a slight edge over LCD displays in regards to screen dimensions, as they can support virtually any custom resolution or aspect ratio. As a newer technology with more versatile backlight electronics, LED screens are often thinner and lighter than LCD screens.With standard HDMI ports, both technologies offer optimal connectivity to external multimedia sources, with great picture and sound qualities. While ports such as RS-232 are less common in new screen models, they could be necessary to certain organizations and are more commonly found in older LCD models.

Energy Saving

While power usage is roughly proportional to screen size, LED screens offer greater energy efficiency per pixel than LCDs. This is largely due to LED displays utilizing newer technology, and their ability to dim backlights (such as for absolute black). For large-scale and prolonged use installations—these differences can add up. However, LCD displays have been historically optimized to mitigate burn-ins—discolorations on the screen due to long, disproportionate, and consistent use of pixels.A display management system allows for content to be dimmed, switched off, or turned off to optimize pixel usage and power consumption; otherwise costlier features when built-in.


Ease of transfer

Most times, video walls are not meant to be used in one location only, think concerts or ads that only have a fixed contract to runina certain spot.LED displays weigh less than LCD walls and are therefore easier to assemble, dismantle, and transport from one location to another.On the other and LCD video walls don’t have much of the ease of moving capability that LED can offer.LCD screens need huge containers to be transferred. An elevator and more space may be required when transporting an LCD video wall.LED also needs lesser maintenance and replacement as compared to LCD video walls making it a far more economical choice for long-term use.


Software

The software to be used with your chosen video wall should work well with the display otherwise, you won't be able to make the best use of the display.It should be easy to use and give the user the ability to display content in real-time.A bonus if it can save the added expense of additional hardware and processors.In choosing a software also consider the type of content that will be shown, whether the content requires only one screen or it needs multiple screens. It’s also worth mentioning here the type of users or the people who will operate the video wall.LCD or LED displays that will be used in conference rooms should be easily used by newbies or amateurs so a user-friendly software is a better choice.On the other hand, people who run security control rooms may be more tech-savvy so they may not prefer a simple software for video walls.


Indoor / Outdoor

Bright sunlight may make it difficult to see images on LCD displays.To make up for the ambient brightness, outdoor LED displays have more bright LED's for every pixel. This makes outdoor displays many times brighter than the indoor type compared to Indoor displays which require less brightness.A video wall’s performance can also be affected the environmental factors such as ambient temperature, humidity, and air quality.In the case of video walls that will be used for ads at or near coastal cities, there is increased risk for erosion due to the presence of salt and higher moisture content in the air as compared to cities that are far inland.These factors will require you to select a LED video wall that can withstand the effects of environmental and weather factors better.


Distance View

Consider the distance of the viewer.If your ad display is meant to be seen from afar then it is more economical to choose an LED video wall.Much has been promoted about ‘pixel pitch’ which is the distance between two LED lights.To make things simple, the finer the pitch, the close that the audience can look at the display without being able to see the individual lights.Choosing an LCD display for this purpose of displaying ads to passing shoppers from 10+ feet away would be an unnecessary cost as LCD usually costs more.An LED video will do the job just fine.
