Is the brightness of LED display low or high

first understand the ways to improve the brightness of LED display, and what are the advantages of high brightness outdoor display? What are the advantages of low brightness?

1: Indoor LED display
In fact, the brightness of indoor LED display screen is required to be lower than 800cd / m2, because the interior light is dark and the brightness is too high, we will feel dazzling and uncomfortable. Now we usually use the brightness of interior screen.  tells you that most of them are around 1200-1600cd, and some people ask why? Why don’t you use a small chip to reduce the cost? Ha ha, you don’t understand. The indoor display requires low brightness / high gray / no shadow. The so-called low brightness means that the brightness must be controlled below 800cd or even lower
2: Outdoor L
The brightness of LED products depends on the quality of LED chip and the driving current. If a low-quality LED has a higher driving current, it will be brighter than a high-quality LED at the initial stage of operation. However, the excessive current will make the LED heat too fast, and the final result is that the brightness becomes dark or burned. In order to benefit sales, some manufacturers choose inferior chips and use the method of increasing the driving current to improve the brightness of LED lamps to mislead buyers, but this will lead to a significant shortening of the service life of LED lamps
However, some manufacturers vigorously publicize that the brightness is low. On behalf of manufacturers, such as qianglijucai, qianglijucai takes the channel route. The so-called channel route is to wholesale low-end products, while high-end products are auxiliary. Since the cost of low-end materials is an inevitable factor to be considered, small chips will be used in chip use. As a channel enterprise, it will not dare to increase the current excessively if it wants to be a brand, So the brightness experience of the product is sacrificed. For example, outdoor LED display requires that the brightness must reach 7000CD / m2, and the picture quality is not affected by sunlight
Besides, LED display is an energy-saving product, which can save electricity
It’s true that led can save energy. The effective conversion rate is as high as 60%, which is much higher than that of incandescent lamp by 20%. But there is a saying that the camel is thinner than the horse. In recent years, the advertising industry has developed rapidly! LED big screen also quickly fire up! But the power consumption of LED large screen is a problem! High power! A 100 square meter display costs $1.2 million a year! The key is, the area is too big!!!
To sum up, for outdoor LED display products, the power consumption is relatively large, so it can not be absolutely said that outdoor LED display can really save energy. At present, LED display manufacturers are also focusing on the research and development of energy-saving LED display, we also look forward to the emergence of more excellent energy-saving LED display products.
