In the digital advertising and commercial display areas, high-resolution LED displays are becoming the mainstream choice. Whether it is shopping mall advertising, stage background or corporate exhibition hall, a high-quality LED screen can greatly enhance the visual impact. But in the face of the dazzling array of products on the market, how should ordinary buyers choose? This article will disassemble the core knowledge of high-resolution LED displays for you to make informed decisions.
- What is a true high-resolution LED screen?
Many merchants claim that their products are "HD LEDs", but the actual resolution may not be ideal. True high-resolution LED displays usually have the following characteristics:
Small pixel density: This refers to the distance between the center points of two adjacent LED beads, in millimeters. The smaller the common numbers such as P1.2, P1.5, P1.8, the higher the pixel density, and the better the close-up viewing effect. Here is P1.2 indoor LED display: price, technology and application.
4K/UHD compatibility: High-quality high-definition LED screens should support at least 3840×2160 UHD resolution, and some professional-grade products can reach the 8K standard. Provide you with UHD LED vs HDR LED - a comprehensive analysis and purchasing guide.
High refresh rate: A refresh rate not lower than 1920Hz can ensure that the dynamic picture does not flicker, especially when shooting, there will be no scan lines.
- Key differences in indoor and outdoor applications
Indoor LED screen:
A smaller pixel pitch is usually used (P1.2-P3).
Brightness is between 800-1500nit.
Emphasize color reproduction and viewing comfort.
Commonly found in conference rooms, retail stores, exhibition halls and other places. Take you to learn about the LED display in the conference room in 5 minutes.
Outdoor LED screen:
Large pixel spacing (P4-P10)
Brightness up to 5000-8000nit to fight against sunlight.
It has waterproof, dustproof, ultraviolet ray resistance and other protection functions.
Used for exterior walls, squares, sports stadiums, etc. Stadium LED display: enhance the event experience and passion!
- Interpretation of core parameters
Brightness (nit): The brighter the better. 800-1500nit is enough for indoor environments, and more than 5000nit is required for outdoor environments. If the brightness is insufficient, it cannot be seen clearly in the sun. Too high will cause light pollution and waste of energy consumption.
Contrast: The static contrast of a high-quality LED screen should be ≥5000:1, which determines the layering of the picture and the details of the dark part.
Color gamut coverage: Professional-grade products should cover ≥90% of the NTSC color gamut, and high-end models can reach more than 110%, ensuring bright and accurate colors.
Grayscale: at least 16 bits, high-end products reach 20 bits, which affects the smoothness of color transitions.
- 5 practical skills when purchasing
Viewing distance calculation: The easiest formula is: optimal viewing distance (meters) = pixel spacing (mm) × 2. For example, the best viewing distance for P2 screen is about 4 meters. Provide you with a guide to selecting LED display spacing.
Field test: Providers are required to play multiple content tests, with special attention:
Solid color screen check for bad points
Gradient screen to see color transition
Quick motion picture observation and drag
Energy consumption evaluation: LED screens are long-term electricity use equipment, with a power consumption difference of 100W per square meter, and the annual electricity bill gap may reach thousands of yuan.
Maintenance convenience: Ask about the difficulty of module replacement, whether professional tools are needed, spare parts supply cycle and other practical issues.
Control system: Confirm whether the supporting control system is stable, whether the software is easy to operate, and whether it can support multiple signal inputs.
- Clarification of common misunderstandings
Misunderstanding 1: "The higher the resolution, the better"
→Facts: Must match usage scenarios. Choosing too high resolution for large screens for long distance viewing is a waste of resources.
Misunderstanding 2: "Imported brands must be better than domestic ones"
→Fact: China's LED display technology is leading the world, and many international brands are actually manufactured by Chinese companies. China LED screen factory, this is more reliable!
Myth 3: "The lower the price, the more cost-effective it is"
→Fact: Low-priced products may use inferior lamp beads, and the brightness attenuation will be severely reduced after 2-3 years, and the maintenance cost will be higher.
- Maintenance points
Regular cleaning: Use special cleaners and soft brushes to avoid scratching the surface.
Appropriate rest: After working continuously for 72 hours, the machine should be turned off for 4-6 hours to dissipate heat.
Environmental control: Maintain ambient humidity of 30%-70%, and temperature of -10℃~40℃.
Professional maintenance: Full inspection is carried out by technicians at least once a year.
- Future development trends
Micro-pitch LED: The pixel spacing exceeds below 1mm, and the picture quality is comparable to OLED.
Transparent LED: It maintains transparency and displays content while maintaining transparency, suitable for window display. Retail displays 7 advantages of using LED transparent screen rental.
Interaction functions: Integrate touch, face recognition and other technologies to enhance the sense of participation.
Energy-saving innovation: New driver IC and lamp bead technology can reduce energy consumption by more than 30%.
Choosing a high-resolution LED display is a technology procurement that needs comprehensive consideration. It is recommended to communicate in-depth with professional suppliers before making a decision based on factors such as actual budget, installation environment, content requirements and viewing distance. Remember, a high-quality LED screen can be used for 8-10 years. Although the initial investment is high, the long-term returns are more worth looking forward to.
