Technology | High brightness is good? How to choose the brightness of LED display screen in one article?

LED display brightness, refresh rate, contrast, grayscale... There are countless professional terms in the LED display industry, how much do you know. Is it better if the brightness of the LED display screen is higher? This article tells you how to choose the brightness of an LED display screen.

1、 What is the "brightness" of an LED display screen?

The brightness of an LED display screen refers to the intensity of light emitted per unit area in the normal direction (vertical direction) of the display screen, measured in nits (1 nit=1cd/m ²).

Assuming there are 1000 light beads on a 1 ㎡ LED display screen, with each bead having a brightness of 5 candela (cd), the brightness of this screen is 1000 x 5cd/㎡=5000 nits.

2、 Why is the 'brightness' parameter crucial

The brightness directly determines the visible distance, adaptability to the environment, and information transmission efficiency of the display screen. The "bottom line" of brightness varies depending on the viewing distance and environment.

Brightness directly affects the user's viewing experience. Excessive brightness can cause dryness/eye fatigue in the viewer, while insufficient brightness can lead to a decrease in color saturation, affecting the realism of the image.

As the brightness of the display screen increases, the power consumption also increases accordingly. Meanwhile, long-term high brightness operation beyond the load will accelerate the aging of the lamp beads. Reasonable brightness selection and design can save energy, environment, cost, and extend the lifespan of the display screen

*Note: Brightness is only one of the key factors affecting the display quality, viewing experience, and service life of LED displays. In practical applications, other factors should be considered comprehensively.

3、 How to choose the brightness of LED display screen?

For outdoor strong light environments, such as squares, sports venues, and other open spaces, direct sunlight is strong and the surrounding environment has complex lighting. To ensure that the content on the display screen is still clear and visible in sunlight, it is recommended to choose an LED display screen with a brightness of ≥ 6000 nit. Only in this way can the audience easily capture every detail on the screen while watching from a distance, without missing any exciting moments.

Semi outdoor environments, such as canopies, shop windows, etc., have relatively complex lighting conditions, neither as intense as outdoors nor as stable as indoors. In this case, choosing an LED display screen with a brightness of 2000-4000 nit is more suitable. This brightness range can achieve adaptive adjustment under multiple lighting conditions, ensuring that the display screen presents clear and vivid images regardless of day or night, sunny or cloudy.In indoor environments such as exhibitions, conferences, press conferences, etc., the viewing distance is relatively close and the ambient lighting is relatively soft. Generally speaking, a brightness range of 600-1500 nit is sufficient to meet conventional requirements. Within this brightness range, it can ensure that the audience can see the screen content clearly and avoid discomfort caused by excessive brightness.

It is worth mentioning that in the leasing industry, brightness adjustability is particularly important. Due to the fact that the leased LED display screen may be used in different venues and environments, with varying lighting conditions and different viewing needs. Therefore, LED displays equipped with precision dimming systems and technologies such as wide color gamut, high contrast, and high refresh rate have become the preferred choice. Through these technologies, LED displays can achieve flexible brightness adjustment in various environments, ensuring a perfect balance between brightness and image quality, thereby reducing procurement and operating costs and improving the economic benefits of leasing.

In short, the brightness selection of LED displays is an art that requires us to comprehensively consider various factors and find the best balance between viewing experience and practical efficiency. Only in this way can LED displays maximize their value in various fields and bring us a more exciting and comfortable visual feast.
