We believe an LED display or screen must be as large as possible. In the end, there's no limitation on size, and the larger the display, the more of a direct effect it generates! What Is just a Good Pixel Pitch?
Some individuals say that the pixel pitch should reflect how far the viewer will soon be standing, and this, subsequently, should dictate the pitch size, but that is not the case. One way to understand this is to think about, for instance, a standard 55″ television having an HD resolution of 1920 x 1080 pixels and compare this to another 55″ TV, but this time around with a 4k resolution of 3840 x 2160 pixels. The 4k resolution looks far more impressive, but the physical screen size is precisely the same. We could use this same comparison with LED displays. The larger the LED screen and the more overall pixels (resolution), the greater looking the display. However, a very good principle for newcomers to LED is that for every 1m you stand away from the screen, you should have 1mm of pixel pitch. So, as an example, if you don't wish to see every individual pixel when viewing from 2m, you will have a pixel pitch of 2mm, and for 3m, it must be 3mm, and so on. What Size LED TV Should You Buy?
When speaking about CRO tube televisions, their panels weren't manufactured from ultra 4K or HD technologies. Consequently, your eyes failed to catch on any imperfections in the display panel. However, if you are buying an LED screen, you must consider how big is the TV screen for the best results. If the screen is too small and doesn't have a higher enough pixel density, the image will be pixelated. Exactly the same goes for if the LED screen is very large, although a really silver screen typically doesn't require a low pixel pitch as you are able to achieve a high res with a relatively small pixel density.
As traditional screens are actually centered on ultra 4K or High Definition technology, they're usually viewed from the close distance and achieve an excellent viewing resolution. Most LED screens are fairly big compared, and that is where they show a benefit over traditional displays.
In the event of LED display panels, how big is the screen is usually above that of a normal 80″ LED panel, and even as of this size, the pixel pitch will have to be fairly low. That isn't to say a direct view LED screen has to really have a similar resolution to a conventional TV screen because the direct view LED delivers an alternative type of image. For instance, a traditional TV screen could have an HD resolution of 1920 x 1080 pixels but a primary view LED display would still deliver a really crisp and vivid image at far less than this. Something to consider is that the closer you view a primary view LED display the more visible the average person pixels become.
