![]() The maximum brightness for led pixel display means under certain environment, the brightness under the maximum gray scale and lighting condition. To deal with this situation, customers can observe the delivered contents from front and side to check whether the images are clear or not. However, some manufacturers try to disorient customers by higher brightness but smaller viewing angle. Customers can decide to choose DIP or SMD depending on audiences’ group and the lighting conditions on installation environment.įor indoor applications, brightness is not the key element, SMD product is perfect. DIP product owns higher brightness but smaller viewing angle while SMD products fit with larger vertical viewing angle but lower brightness. There are Horizontal viewing angle and Vertical viewing angle.įor outdoor led display applications, both DIP products and SMD products are great choices. The viewing angle means when the brightness from viewing direction is the half of brightness at normal line to the led wall display, the angle between Horizontal and Vertical viewing and Normal Line. For a good quality led display, blue color and green color should control their wave aberration no more than 3nm and red color wave aberration no more than 5nm in central wavelength. If it shows not uniform color that means wave aberration is larger than it should be. ![]() If it shows as deeper blue, red and green, or lighter ones, that means partial wavelength. The color shown in the central wavelength is the pure blue, pure red and pure green. Method two: control the whole led pixel display to deliver red color, green color, and blue color in order. If there are a little bit red or blue that means both raw material and manufacturing technology are less desirable.ī. This should be pure white overall hd led wall. Method one: control the whole led display to deliver white color. The way to check is easy, even without professional devices they can still to define this through observation.Ī. Wavelength decides whether the color led display delivers is uniform or not. ![]() Buying a led screen wall is not like buying speakers or lights off-the-shelf where the only consideration is the best choice under the circumstances, but where the specifications of the units themselves cannot be altered in any way.Īs the wide application of led video wall, to choose a good quality led pixel display is not so easy for so many technical terms to refer to. However, this perception is the farthest thing from reality. What are the critical factors that will enter making that decision: price, components, and length of warranty percentage of free spare parts reputation of supplier for references?Īt first blush, a led wall seems like a very simple, straightforward piece of hardware. It also includes manual lens shift, wireless networking with enterprise-level security, and advanced installation features.Consultants, architects, integrators, and end users must establish their priorities when buying a led video wall. Plus, it features a Dynamic contrast ratio of up to 2,500,000:1. And, it offers virtually maintenance-free operation for the life of the optical engine6.
