Selecting an ideal video wall solution can be a complex task because of the wide range of options that are available. One of the most important component of a video wall solution is the display type and the common types that people look at are LCD video wall and LED video walls. Most often than not, it becomes fairly difficult to choose the right one and this articles attempts to help you identifying the right display type based on your needs.
|Hardware||Fairly simple. Figure out how large you want the images to be and add additional LCD displays to create the video wall||Resolution needs to be decided first as LED panels don’t scale easily as the pixel pitch defines the resolution.|
|Viewing distance||Indoor viewing, close distance viewing – can salce to Full HD, 4K or even 8K resolutions||Mainly outdoor viewing. Handles ambient lighting better than LCD. With the advent of sub 1mm pixel pitch, it is possible to view from a closer distance. However, it comes at a cost|
|Software||Integrators just need to select a media player and have it connected to the HDMI port. They can select a media player with the right amount of outputs for a video wall||Integrators may have to connect the media player to the video wall controller|
|Cost||Fairly straightforward and a cheaper option||Pricier option at this point in time, while the costs are decreasing rapidly|
|Resolution||It is very sharp – can display texts, images and videos in detail||For use cases that require the finest resolution, this may not be an option|
|Bezels||When multiple LCD panels are put together to create a video wall, the size of the bezels or seams may work against LCD. However, the size of bezels are reduced considerably and only exists as a line nowadays||This is a clear advantage for LED walls as there are no bezels irrespective of the size of the display. This helps you have a seamless video wall|
|Touch Interactivity||Can be configured to provide multi-touch control, enabling users to directly interact with the display||Not at all applicable|
These are only some pointers to help you get started in choosing between the popular choices of LCD and LED video walls.
