The resolution and pixel spacing of the LED display is a key parameter that determines the display effect. This article will in -depth analysis of the visual characteristics of the LED display from technical principles, application scenarios, and viewing distances, and discuss the environmental protection processing scheme of the abandoned display.
- Technical analysis of resolution and pixel spacing
The resolution of the LED display is determined by the number of pixels, and the pixel spacing (Pitch) refers to the distance between the neighboring pixels, and the unit is millimeter. Common pixels range from P0.9 to P20, the smaller the distance, the higher the resolution. For example, the pixel spacing of the P2.5 display is 2.5mm and the pixel density per square meter is 160,000 points. What is a thin spacing LED display?
The resolution is closely related to viewing distance. According to the SMPTE (Film and TV Engineer Association) standard, the best viewing distance = pixel spacing/(0.000291X visual acuity). Taking the P3 display as an example, the best viewing distance is 3/(0.000291 × 1) = 10.3 meters.
- Application guide for different scenarios
Indoor application scenarios usually use small spacing LED display. The conference room recommends P1.2-P1.8, and the best viewing distance is 2-4 meters; the monitoring center uses P0.9-P1.5 to ensure close definition. According to market research, the size of the small spacing LED market in 2022 reached 1.5 billion US dollars, with an annual growth rate of more than 30%. There are small spacing LED display prices and purchase guidelines.
Outdoor display needs to take care of the viewing distance and cost. Advertising screens are often P6-P10, suitable for 15-30 meters to watch distance; stadium uses P4-P8 to meet long-distance viewing requirements. Studies have shown that the P6 display is the best clarity at a distance of 30 meters and the highest cost performance. Sports LED scoring board: an indispensable technology for professional events!
- Environmental treatment of abandoned display screens
The LED display recycling uses modular disassembly technology. First, the metal framework, power module and LED module are separated, and the metal recovery rate can reach 95%. The LED chip extracts precious metals through a chemical immersion method, with a recovery rate of more than 98%.
Establishing a comprehensive recycling system is crucial. Samsung Electronics has set up a recycling center in the world. In 2022, it handled 120,000 square meters of abandoned display, and the re -utilization rate of materials reached 92%. The lead -free welding process is adopted to reduce environmental pollution.
The development of LED display technology is breaking through the resolution limit. Micro LED technology can achieve P0.4 ultra -small spacing and 8K resolution. In the future, with the advancement of recycling technology and the improvement of environmental protection standards, the LED display will achieve better visual experience and higher environmental value.
