How to choose a right display – color temperature

The color temperature of a light source is the temperature of an ideal black-body radiator that radiates light of comparable color to that of the light source. Color temperature is conventionally expressed in kelvins, using the symbol K, a unit of measure for absolute temperature.

Take the iron as an example, we may understand that as the temperature goes higher, the color of the iron will go to red, yellow, and white. Color temperatures over 5000 K are called cool colors (bluish white), while lower color temperatures (2700–3000 K) are called warm colors (yellowish white through red).

When we find image colors don’t match or have differences with the original materials on the screen, the images are seriously distorted, which is associated with color temperature of white balance on LED display. If people watch the display screen directly, the color temperature of white balance between 6500k and 8000k is ok, and if the display is used for broadcasting, the color temperature should be 5500k so that to present an authentic image through the video cameras.

But 5500k may not a be suitable for people live in different latitude. Normally the higher the latitude is, the color temperature that human eyes feel comfortable might be higher. For example, for a display, it is better to set the color temperature of the display that will be installed in Stockholm to 7200k; and to set the color temperature of the display that will be installed in Manila to 5500k.

Hot fine pixel pitch LED dispaly markets, are you tempted?

In the past 2016, the LED display industry rise sharply, especially fine pixel pitch LED display. Its maturity and outbreak led to the rise of commercial LED display applications. Fine pixel pitch LED has been gradually replacing LCD, DLP and other traditional large screen splicing market in more and more fields, mainly due to the growing demands for high-definition display. In brief, perfect display effect of fine pixel pitch LED display can better meet the practical needs of customers.

At present, the market of fine pixel pitch LED display has entered a growth period, according to latest statistics, in 2016, fine pixel pitch LED consumption reach 29 billion particles,it is expected that the consumption will reach 188.9 billion particles in 2021, the annual compound growth rate will reach 46%, the output value is expected from 300 million US dollars in 2016 up to 800 million US dollars in 2021 , the annual compound growth rate will up to 21%.

How to play "new retail" by CRIUS of QSTECH?

Retail is one of the most important application areas in the advertising industry. In the LED display industry, the LED poster is the potential stock of retail media and is developing into the mainstream carrier of retail advertising with rapid pace. When we are strolling in the bustling commercial center, passing the fashionable clothing store, the warm and beautiful flower shop, the corner of the elegant coffee shop, etc., all kinds of exquisite shops almost show their goods by multifarious LED poster, attracting pedestrians. Colorful and vivid pictures always make people stop to enjoy, and slowly attracted, then into the store to watch, to buy. This is the huge magic of LED poster for traditional retail business.

However, with the development of shared economy, "new retail" concept is put forward by more and more people，the last time is mentioned by Ma Yun in Hangzhou in 2016 Yunqi conference speech, he said: "In the next ten to twenty years, will no longer have e-commerce, online and offline and logistics must be combined in order to be born really 'new retail'.

The "new retail" in future is a "scene experiential marketing" and different from the traditional business, which is a combination of retail-based form. It’s pay more attention to participation, experience and feelings of consumers. In the process of experience to complete the understanding between the brand and the user, the value of sharing between users and users.

How to choose a good LED display?

LED display is not cheap. How to choose a LED display with good cost ratio? Let’s discuss this from 7 points: The maximum brightness, color temperature, refresh rate, wave length, viewing angle of the LED, PCB design, and average power consumption.

Today we will talk about the maximum brightness.

First of all, we must have an idea that the brightness is not the higher the better. Higher brightness means higher purchase and power cost, and faster component decay. The maximum brightness is the brightness of the LED display when it shows the maximum grayscale and brightness under a certain surrounding illuminance. The maximum requirement is different for different service environment. Normally if the display faces the direction of sunshine, 4000CD/m2 is good enough; if it directly faces the sunshine, 7000CD/m2 is bright enough to show qualified images under sunshine. If the display faces the west or east direction, 5500CD/m2 is good enough.

Theoretically, a display with 5500CD/m2 maximum brightness can meet the most using environment. It is the best cost-ratio maximum brightness.
