LED Display Classification

There are many types of LED display screens, which are roughly classified as follows:

LED digital display: The display device is a 7-segment digital tube, which is suitable for making digital display such as clock screens and interest rate screens. LED dot matrix graphic display: The display device is a dot matrix display module composed of many evenly arranged light-emitting diodes, which is suitable for playing text and image information. According to the use environment, the indoor screen area is generally less than ten square meters, and the dot density is high. It is used in a non-direct sunlight or lighting environment. The viewing distance is a few meters away. The screen does not have the ability to seal and waterproof.

The diameter of the light-emitting point is small, generally 3-8mm in diameter. The outdoor screen area generally ranges from a few square meters to tens or even hundreds of square meters. The dot density is relatively sparse (mostly 1000-4000 dots/m2), and the luminous brightness is 3000-5000cd/m2 (different orientations, different brightness requirements), which can be used in sunlight When used under direct sunlight, the viewing distance is tens of meters away, and the screen has good wind and rain resistance and lightning protection capabilities. The basic unit of outdoor screen light-emitting is pixels, and the center diameter of the light-emitting points of the pixels is relatively large, such as P10mm, P12mm, P16mm, P20mm, P24mm, P26mm, etc. The semi-outdoor screen is between the outdoor and the indoor. It has a high luminous brightness and can be used outdoors in non-direct sunlight. The screen has a certain seal, usually under the eaves or in the shop window.
