According to the purpose and extent of use, LED display screens are available in a wide range. Each is known for having a unique set of characteristics, be it the color support, screen resolution or workable lifespan. Some of the common types are:
DIP
COB- chip on board
SMD- surface mount device
Apart from the first two, SMD LED screens are further divided into two subcategories: Black SMD and White SMD. Each is capable of providing a bunch of facilities that users would not find in any other option available in the market. Although both contain SMD LED Chips, it is their structure, design and a few features that create a difference. Buyers will have to look at those different before they end up on making a decision for either of them.
Comparison Between Black SMD and White SMD LED Display Screen
Below is a precise comparison of what makes a black SMD LED different from a white one:
Black SMD LED Display Screen
For outdoor advertising screen, Black SMD LEDs have turned out to be the best option. They are capable of providing the best viewing experience. There was a time when advertisers used to have LED screens for the same purpose but they weren’t successful in providing the required visual experience. Sometimes, the brightness wasn’t up to the required level while the other time, it became so bright that it caused light pollution. So, to deal with visual problems, manufacturers introduced a black SMD LED screen whose major purpose is to cater all customer requirements and provide the following benefits to the fullest:
High contrast ratio: One of the incredible features of black LED display is the surety of getting high contrast ratio. As compared to other LED displays, SMD versions are way better and brighter. They are capable of providing an incredible viewing experience. Their blackbody is the secret behind offering a good contrast ratio- which is measured as 3000:1. This ratio has a direct impact on viewing experience as it makes the images clear and maximize displaying effect.
Vivid colors: Another positive point of having a good contrast ratio is the surety of having rich and vivid colors. While they will be more gentle and near to the real colors, they do not affect viewers’ eyes in any way. They just give an amazing visual experience as the colors (such as dark green, black or grey) remain in control due to the blackbody, unlike the white body where the color combinations are affected by the structure and do not offer the required level of purity and clarity.
Non-reflective: As a matter of fact, black is a non-reflective color and therefore, it doesn’t reflect the light no matter how bright it is. It doesn’t allow extra light to affect the viewing experience, thereby ensure more vivid, clear and purer colors of the images. This feature also makes black SMD LED a better choice for stage and other purposes where there is a lot of light.
Amazing appearance: It doesn’t matter if people view black LED screen from the side or front, it always remains black. When turned out, it will maintain color uniformity and looks incredible, thereby making the experience better than a normal SMD LED.
White SMD LED Display Screen
When it comes to the usage of white SMD chip LEDs, they are usually preferred in status indication, white appliances and goods, automotive interior, industrial control and measurement systems, push button backlighting and symbol lighting to ensure quality and efficiency in consumer goods and computer peripherals.
Here, the worth mentioning fact is that unlike their name, white SMD LEDs are not intended to produce white light. It comes in two different ways:
A blue LED having a phosphor coating that converts blue color into white by the process of fluorescence.
Green, red and blue LEDs that are combined on different intensities to produce white light.
