LED Screens: The Pinnacle of Modern Visual Technology, Redefining How We See the World

I. Core Principle: Everything Can Be "Illuminated"

II. Key Parameters: Decode the Screen’s "ID Card"

1. Pixel Pitch

• P2.5: Pixel pitch of 2.5mm. Suitable for medium-sized meeting rooms, hotels, etc., with optimal viewing from a few meters away.
• P1.8: More delicate, ideal for high-end exhibition halls and command centers.
• P10/P16: Commonly used for outdoor advertising screens. With longer viewing distances, a larger pixel pitch is acceptable.
• Golden Rule: The closer the viewing distance, the smaller the required pixel pitch—and the higher the screen cost.

2. Resolution

3. Brightness

• Indoor screens: 800-1500 nits are sufficient; excessive brightness can be dazzling.
• Outdoor screens: Need to reach over 5000 nits to resist direct sunlight and ensure clear images.

4. Refresh Rate

5. Contrast Ratio

III. Main Types: Find the Right One for You

1. Classified by Usage Environment

• Indoor LED displays: Lightweight, thin, and moderately bright, focusing on color and detail.
• Outdoor LED displays: High-brightness, waterproof, dustproof, UV-resistant, and structurally robust to withstand wind and rain.

2. Classified by Product Form

• Fixed-installation displays: Permanently mounted in one location, such as billboards and stage backdrops.
• Rental displays: Quickly assembled from multiple lightweight cabinets, easy to transport and disassemble repeatedly. Suitable for events like concerts and exhibitions.
• Creative irregular-shaped displays: Breaking away from traditional rectangles, they can be curved, spherical, wavy, etc., with strong visual impact. Commonly used in brand exhibition halls and commercial spaces.

3. Classified by Technical Route

• Through-hole type: Chips are "standing," offering high brightness. Mainly used outdoors.
• Surface-mount type (SMD): Chips are "laid flat" and soldered onto the board, providing a wide viewing angle and soft colors. The mainstream choice for indoor screens.
• Chip-on-Board (COB)/Glass-on-Board (GOB): More advanced packaging technologies with stronger protection and reliability. The future trend.

IV. Application Scenarios: Ubiquitous Visual Engines

• Business and Advertising: Facades of landmark buildings, shopping mall atriums, bus and subway advertisements—maximizing brand exposure.
• Culture and Performances: Concerts, theaters, music festivals—creating immersive and transformable dream stages.
• Broadcasting and Conferences: TV studio backdrops, corporate meeting rooms, command and dispatch centers—delivering high-definition, stable information presentation.
• Sports and Events: Stadium perimeter screens, scoreboards and timers—capturing wonderful moments in real time and igniting the venue atmosphere.

V. Purchasing Guide: Five Steps to Lock in the Best Solution

1. Clarify usage and budget: Is it for long-term display or temporary events? What is the budget range? This is the starting point for all decisions.
2. Determine viewing distance: Calculate the average distance between the audience and the screen, then reverse-calculate the most cost-effective pixel pitch.
3. Choose the installation environment: Indoor or outdoor? This directly determines the screen’s brightness, protection level, and structural requirements.
4. Evaluate suppliers: Look beyond price—focus on the manufacturer’s cases, technical support, and after-sales service capabilities.
5. Seeing is believing: If possible, request to view samples or conduct on-site inspections of case projects to personally confirm the display effect.

VI. The Future Is Here: Development Trends of LED Screens

• Micro-pitch development: Pixel pitch continues to shrink, entering the "micro-pitch" era below P1.0, gradually expanding into the high-end home display market.
• Smarter screens: Integrating intelligent sensors to achieve automatic brightness adjustment, automatic fault detection, and other functions.
• Transparency and flexibility: Transparent LED screens bring a more technological feel to window displays; flexible screens make curved and rollable forms possible.
