In order to achieve good energy-saving goals, excessive pursuit of high brightness is contrary to energy-saving. So what is the potential relationship between 'high brightness' and 'high energy saving'?
At present, the most popular 10000cd/m2 high-brightness LED lights in China basically use large-size LED chips. This large-size LED chip is commonly used by most LED display manufacturers as the mainstream market, and there is no core technology to speak of. As we all know, the brightness of the LED screen is proportional to the driving current of the LED lamp. The brightness of 10000cd/m2 is nothing more than increasing the driving current of the LED lamp. However, the physical characteristics of LED lights will be inevitable: high-brightness LED lights must be accompanied by high attenuation and low stability. High attenuation is not conducive to the long-term use requirements of the LED display, and it will become a congenital defect of excessive pursuit of high brightness, and this congenital defect will damage the life and picture effect of the LED display all the time and like a multiplier effect.
Taking the high-brightness PH16mm display as an example, the technical parameters of this high-brightness LED lamp show: the brightness of 10000cd/m2 will be seriously attenuated to 8000cd/m2 within 1.5-2 years, and its annual attenuation rate reaches 20% the above. In fact, consumers can verify in a very simple way, that is, look at the effects of several high-brightness displays that have been in operation for more than 2 years and used for more than 12 hours a day. What's more serious is that after the brightness has dropped from 10000cd/m2 to 8000cd/m2, its high working current situation has not changed, and its brightness attenuation speed will be more multiplied, causing the later attenuation speed to speed up several times and become a high attenuation. Display screen. Moreover, it exists in the vicious circle of brightness attenuation, which cannot meet the requirements of long-term use at all.
In order to avoid LED Light module pollution and meet the requirements of environmental protection laws and regulations, the brightness standards of LED electronic display screens are different day and night. As we all know, reducing the brightness will more or less lose the grayscale, the greater the brightness adjustment, the greater the grayscale loss. Therefore, if the initial brightness value of the LED display during the day is set to 10000cd/m2, when the brightness is reduced to 800cd/m2 at night, either the grayscale is extremely lost, making the night image quality very poor; or the brightness cannot be adjusted to the night The use of standard requirements, and the formation of heavy LED Light module pollution.
From this point of view, the market’s excessive admiration of the value of high brightness does not mean technological leadership in terms of LED electronic display manufacturing technology, but a high current and high brightness that seriously sacrifices the life of the display screen. On the contrary, it is inevitable that people will feel flashy and stretched.
Excessive pursuit of brightness should belong to a market misunderstanding. When the technology has not reached the corresponding level, or the bottleneck that the technology cannot solve at all, and the user has too high requirements for the highlight, it ignores the LED electronic display The effect of brightness on grayscale has a certain impact on the balance of the product.
