There are several specifications for LED display screens: model specifications, module size specifications, and chassis size specifications. Here we will mainly talk aboutIndoor LED display screenThe model specifications used are selected based on the display size ratio when designing the module and box.

Indoor LED displays mainly use P1.9, P1.8, P1.6, P1.5, P1.2, P0.9, etc., while in the industry, those below p2 are called small pitch LED displays.

Why are small pitch LED displays used indoors? Because when viewed indoors at close range, the image on the monitor needs to be clear and the brightness should not be too high. However, regular P3 and above models have higher brightness, which can easily cause visual fatigue when used indoors for a long time, making them unsuitable. In addition, LED display screens are made of individual light beads, and the larger the model, the stronger the graininess. When P3 is observed up close, it can already clearly feel the graininess, and the more you look inside, the stronger the graininess.

The reason why LED display screens are divided into outdoor and indoor is that their brightness cannot meet the outdoor standard when the model is below P2; Secondly, due to close range viewing, large-sized LED displays have a noticeable graininess and are not suitable for close range viewing; Thirdly, due to different environments, the required configurations may also vary. Outdoor equipment requires good protection such as shock resistance, waterproofing, moisture resistance, electricity resistance, and heat dissipation;

For indoor LED display screens, I don't know how to choose from the above models. You can simply choose based on the viewing distance. If you really don't know this knowledge, you can consult Shenzhen Chuangmei New Technology Co., Ltd., and we will answer your LED display screen related questions online at any time.
