How to identify the quality of LED display?

1. Brightness

The most important index of LED display is brightness, which determines whether the display can show high definition image. The higher the brightness, the clearer the image; the lower the brightness, the blurrier the image. Therefore, when choosing an LED display, you need to consider whether the brightness is sufficient.

The brightness of LED display is usually measured by the following indicators:

1. In indoor environment, it should reach more than 800 cd/m2;
2. In outdoor environment, it should be more than 4000 cd/m2;
3. In different weather conditions, LED display to ensure that its brightness is sufficient, and can work continuously for more than 10 hours;
4. In the absence of wind, the LED display should not have uneven brightness.

2.Coloration

The color of the LED display includes the number of colors, gray level, color gamut size and so on. The purity and fineness of the color will affect the display effect. Gray level is one of the important indicators that affect the quality of the LED display, it indicates a color contains the brightness and darkness, the higher the gray level, the more delicate the color, the clearer the feeling when watching. The general LED display shows the gray scale gray level of 16, we can use this to judge the LED display quality is excellent!

3.Brightness uniformity

Luminance uniformity of LED display refers to whether the luminance distribution between adjacent units is uniform when the full-color display.

Generally speaking, the brightness uniformity of LED display can be judged by visual inspection. Will be the same unit of each point in the full-color display of the brightness value and the same unit of each point in different full-color display of the brightness value for comparison, if the brightness difference is more than 10%, is considered to be a dark spot. You can also use special software to measure the brightness values between different units. Since the LED display is composed of many units, its brightness uniformity is mainly affected by the uneven distribution of brightness between units. Therefore, special attention should be paid to this issue when selecting.

4.Viewing Angle

Visual angle refers to the maximum angle from both sides of the screen body can see the entire screen content. The size of the visual angle directly determines the number of audience display, so the bigger the better. Generally speaking, the visual angle should be more than 150 degrees. The size of the viewing angle is mainly determined by the encapsulation of the core.

5. Color reduction

The color of the LED display changes with the brightness changes, need to show in a darker environment with high brightness, and in a brighter environment with low brightness, need to do color reduction processing, so that the LED display shows the color close to the color of the real scene. This will ensure the color reproduction in the real scene.

Therefore, in the purchase of LED display, the following aspects deserve our attention:

1. Emphasis on the power of word of mouth and brand: no matter what kind of product to buy, we will be more inclined to good reputation, high brand awareness of the product. As the saying goes, "you get what you pay for", big brand products and manufacturers often have rigorous processes and strict management system, so the general quality of the product is more guaranteed, which is also an important basis for our choice.
2. Quality after-sales service: a quality product in addition to its own high quality, but also need to have quality after-sales service to protect. Therefore, when we choose the manufacturer, we need to pay special attention to its after-sales service level, such as maintenance experience, response speed and so on.
3. Technical support and maintenance experience: a mature product not only needs to have professional technical support, but also needs to have rich maintenance experience. Therefore, when choosing a manufacturer, we need to know whether it has a professional technical team and rich maintenance experience to ensure that we can get timely and effective solutions when encountering problems.
4. Consider the applicability of the product: different LED display products have different applicable scenarios and uses, so we need to combine our actual needs to consider when choosing. For example, if our display needs to be installed indoors, then we need to choose a higher brightness, high color reproduction products; if our display needs to be installed outdoors, then we need to choose a higher brightness, waterproof performance products.
