Is the Brightness of LED Electronic Display High or Low?

Jan. 24, 2020

It is often seen in corporate propaganda that LED electronic displays are characterized by high brightness and low grayscale. So is the brightness of the LED electronic display high or good? In fact, first of all, we have to figure out what is the advantage of high brightness of LED display? What are the benefits of low brightness?


First for Outdoor LED Display:

The brightness of LED products depends on the quality of the LED chip and the size of the driving current. If a low-quality LED has a higher driving current, it will be brighter than a high-quality LED at the beginning of the work. However, an excessively high current will cause the LED to heat up too fast, and the end result is dimming or burning. In order to facilitate sales, some manufacturers use inferior chips and increase the driving current to increase the brightness of the LED lamp to mislead the buyer, but this will lead to a significant reduction in the service life of the LED lamp.


And some manufacturers vigorously publicize that the brightness is low. Some manufacturers call that the channel route is mainly low-end wholesale, and high-end is auxiliary. Since the low-end material cost is an inevitable factor, the use of LED light-emitting chips will be small. Chips, as a channel company, and want to be a brand, they must not dare to increase the current too much, so the product's brightness experience is sacrificed. For example, the outdoor LED display requires a brightness of 7000CD / ㎡, and the picture quality is not affected by sunlight. 


Let's talk about high brightness. In the choice of LED electronic display, the higher the brightness of the outdoor display, the better, but it needs a matching drive current to make the LED light-emitting chip produce normal brightness to ensure the LED. Life of the lamp. Therefore, an LED light emitting chip also determines the service life of the LED display.

Secondly, for indoor LED displays, Indoor LED Screen actually requires less than 800cd / ㎡, because the indoor light is dim, and the brightness is too high, we will feel dazzling and uncomfortable, so how much is the brightness of our conventional indoor screen now? Most of them are around 1200-1600CD. Someone asked why? Why not use small chips to reduce costs? In fact, indoor displays require low brightness / high grayscale / high refresh / no shadow. The so-called low brightness means that the brightness must be controlled below 800CD or even lower to meet the indoor senses. High gray Degree is an excessive process from light to dark when we play a movie screen. The more delicate the transition, the higher the gray level, and the higher the corresponding LED display hardware cost. Let's talk about the problem of shadows. In recent years, due to the sharp decline in the price of display screens, channel manufacturers have to control the duplicates again and again. Reduction of materials has led to the existence of shadows in 70% of channel products on the market today. Then to achieve a brightness lower than 800CD and maintain high refresh without losing grayscale, the corresponding LED display hardware cost must be increased to achieve this technology.


In summary, after we know the brightness of LED electronic display, we should know how to choose the brightness of LED electronic display. I hope that through the introduction of Indoor LED Screen Supplier, everyone can understand.
