LED display brightness in the end is good or high?

1: indoor led display articles, indoor LED display actually requires less than 800cd / brightness, because it is too dark inside the brightness is too high we will feel dazzling uncomfortable, then now we are the general internal screen brightness how much, Xiao Bian Tell you that most of them are around 1200-1600CD. Someone asked this is why? Because you don't need a small chip to reduce costs, you don't understand. The indoor display requires low brightness/high grayscale/no shadow. The so-called low brightness means that the brightness must be controlled at 800CD or even lower, in accordance with the senses of the interior. Grayscale is the problem that we play a video picture from bright to dark with an excessively finer grayscale, and then say a shadow.

In recent years, due to the sharp decline in the price of display screens, channel manufacturers have to repeatedly control the weight again. The reduction in materials leads to the existence of shadows in 70% of channel products on the market today. In the current domestic market where this technology can be achieved, not even Fujin Electronics’ subsidiary Mairui Optoelectronics has been unable to control low-light and high-gray. In 2015, a small pitch bid in Fujian was counterbalanced and kept for the next time.

2: Outdoor LED display articles, the brightness of LED products depends on the quality of the LED chip and the size of the drive current. A low-quality LED with higher drive current will be brighter than a high-quality LED in the early stages of operation. However, an excessively high current will cause the LED to heat up too quickly. The end result is a darkened or burned LED. Some manufacturers use low-quality chips in order to facilitate sales, and use the method of increasing the drive current to increase the brightness of the led lamp to mislead the purchaser, but this will lead to a significant reduction in the service life of the LED lamp.

Some manufacturers vigorously promote low-brightness, on behalf of manufacturers such as powerful giant color, strong giant color to take the channel route, the so-called channel route is the wholesale low-end, high-end as an aid, then since the low-end material cost is inevitable to consider Factors, the chip will use the chip to do, as a channel company and want to do a brand will inevitably excessively increase the current, then at the expense of the product's brightness experience, such as our outdoor LED display requirements must reach 7000CD brightness / Brightness, the picture quality is not affected by the sun factor, then for example, powerful giant color represents P10 channel version brightness between 4000-5000CD, this brightness naturally will not affect the life due to the increase of current, but it has an effect, It's still an old saying about the price, you buy a bargain that can be guaranteed to be good.

Let's talk about high brightness, in the choice of LED display, of course, the higher the brightness of the outdoor, the better, but it requires a matching drive current, so that the lamp produces normal brightness, in order to ensure the life of the LED lamp. Let me say that LED display is energy-saving products, can save energy LED energy can really do not fake, the effective conversion rate of up to 60%, compared to incandescent light 20% it is a lot higher, but there is a saying called dead skinny camels more than horses.

In recent years, the advertising industry has developed rapidly! LED large screen also quickly fire up! But LED big screen power consumption is a problem! Power! A piece of more than 100 square meters of display one year to two hundred thousand! The key is, the area is too big! ! ! For example, the average power of a conventional P16 outdoor LED display is 272W/calculated. Assuming that 14 hours a day, China has already installed 12 million. The power consumption of outdoor LED display in China is 16.7 billion kwh, equivalent to about 60 days of power generation in the Three Gorges Dam, equivalent to about 8.5 million tons of raw coal. Consumption, nearly 17 million tons of carbon dioxide emissions. To sum up, for outdoor LED display products, relatively speaking, its power consumption is still quite large, so can not absolutely say that outdoor LED display really can save energy. At present, LED display manufacturers are also focusing on research and development of energy-saving LED display, and we also look forward to more excellent energy-saving LED display products.
