Everyone knows that LED displays are customized products. They are not a simple buying and selling process like general electronic consumer products. Instead, they involve the implementation of a whole set of system design schemes, from pre-sales including design in other related industries to after-sales construction. Installation and maintenance often require integrators to complete. The small picture below will share with you the matters needing attention in the field survey before LED display sales.

　1. Preparation before site survey

　　 It is necessary to communicate with users before departure to understand their specific requirements:

　　① The type and size of the display screen.

　　②Installation environment.

　　③Display content and method.

　　④Communication method.

　　How to determine the model of the display?

a) Display area, if the customer needs to achieve 2K effect (2048 × 1080 resolution, total pixels is about 2.21 million), the pixel density can be obtained by dividing 2.21 million pixels by the area, and then comparing the pixel density of the product to get the correlation Display model. Conversely, the required display area can be deduced by the display model and the required pixels.

　　B) Viewing distance, the calculation method of the visual distance of the LED display:

　　The smallest viewing distance can display smooth images

　　 LED display visual distance = pixel pitch (mm) × 1000 (unit: meter)

　　 The most suitable viewing distance The distance at which the viewer can see a highly clear picture

　　 The best viewing distance of LED display = pixel pitch (mm) × 3000 (unit: meter)

　　 The farthest viewing distance: the farthest viewing distance of the LED display = screen height (m) × 10 (times)
