A room with a lot of natural light is the best place to use LED displays because they look better there. There is another way to show high-quality images on big screens, though. In addition to saving you time and money, the optical projection display improves the look of the images, has almost no pixels, is comfortable to look at, and has better image/colour consistency.
The points to consider here
A high-contrast screen has a robust projector and a high-contrast optical projection screen with built-in contrast filters. Because LED tiles don’t have a way to block out light, the contrast has to be raised to an uncomfortable level for the person looking at it. It’s best to use high-lumen projectors and optical DNP Supernova Screens when you want to match LED displays in most indoor environments.
This is a good thing for outdoor use because LED’s LED solutions have a lot of visual brightness. But if you’re watching them inside for a long time, it might be hard to see. People should not be able to see more than three times bigger images than they are when they look at them with their eyes. Beyond that, the eye gets tired and even hurts very quickly, if at all. If you want, you can turn down the brightness of the LED displays at your discretion. Keep in mind that you’ll lose some contrast and see more pixels as a result.
Because of the high cost of the LED screen hire and the difficulty of installing them, the cost of a direct view display LED wall is very high at the start. There is much more heat and electricity in LED screens than in projection screens, so they need more ventilation and maintenance than a projection screen that doesn’t.
It is looked at how much it costs to buy a 220″ 4K TV.
Consistency in the image
There is a greater chance of black lines interrupting the image on LED displays than on projection screens because video wall hire has much smaller light-up zones than projection screens (pixels). It makes the pixels stand out when you see the image from a longer distance. This is called pixelation, making the image look like a “picture of dots.”
The resolution of most LEDs isn’t excellent compared to the resolution of an optical screen. The space needed to show a 4K image with a 2 mm pitch LED is 33 m2 (357 ft2). This is a massive display in both width and height. Pixel pitch, also known as dot pitch, measures resolution and how clear images will look on the LED wall panel. Resolution is how many pixels there are in a square inch. The smaller the pixel pitch, the less space between pixels, which means more pixels and a better screen resolution. But, how far away the audience will be from the wall needs to be considered. To save money at more significant events where people will be far from the wall, you can use a bigger pixel pitch. You’ll need a smaller pixel pitch for smaller events where people will be closer to the wall. Smaller LED video wall pixel pitches, on the other hand, are better in the long run.
Another problem with multi-panel LED displays is that the LED tiles may not be aligned mechanically. This can make lines in the image that aren’t very appealing. As a result, it’s not unusual to see a single panel that is either dark or color shifts or doesn’t have any color channels at all. In terms of consistency and color rendition over the whole image, projections are better because the image comes from a single source rather than many different cabinets that each drive their image.
Conclusion
To put it simply, an optical projection display is cheap to buy and maintain, doesn’t need complicated software to control it, is easy to set up, and the color consistency is much better.
