Outdoor full-color LED display screen is a very common type of LED display screen. It has been greatly improved not only in the size of sensitive equipment, but also in weight compared with traditional products. The color is more bright and plump, so that you can see more refreshing video. So, if you want to buy high-quality outdoor full-color LED display, what should you pay attention to? The following are some matters needing attention when purchasing outdoor LED display.
1. Look at the flatness of the picture.
In order to prevent display image distortion, the appearance of full-color outdoor LED display must be within 1mm. If this requirement cannot be met, some concave convex phenomena may lead to the problem of visual angle and oblique angle when playing video. Therefore, flatness can be said to be the main factor to judge the high-quality outdoor full-color LED display.
2. Look at the brightness of the screen
Generally, the brightness of outdoor full-color LED display screen shall be more than 1500cd / m2. You can just stop the normal display operation. Otherwise, the brightness is not enough to view the played image content. Therefore, if you want to buy outdoor full-color LED display, you need to check the quality and brightness parameters of LED beads.
3. Look at the white balance of the screen
Because the ratio of red, green and blue primary colors must reach 1:4.6:0.16 to make the picture show the purest white, if the display screen consumed by outdoor full-color LED display manufacturers is slightly biased towards the ratio of three primary colors, it will cause white balance bias and affect the display quality of outdoor full-color LED display screen. Therefore, it is also important to see white balance when purchasing.
