In the LED display industry, SMD (Surface Mounted Device) technology has gradually become the mainstream due to its advantages such as slim profile and high resolution. However, Kingaurora has steadfastly adhered to DIP (Dual In-line Package) technology, continuing to delve deep into the outdoor display market for 16 years. Is this a technical obsession or a keen market insight? Today, we uncover the deeper logic behind Kingaurora's commitment to DIP.
Before diving into Kingaurora's technological choice, it's essential to understand the two mainstream LED display packaging technologies: DIP and SMD.
DIP is one of the earliest LED packaging technologies, featuring cylindrical lamp beads with a spherical top to optimize light projection. Each DIP LED emits a single color (red, green, or blue), so three-color LEDs must be combined to achieve full-color displays. DIP lamp beads are fixed by inserting long pins directly into a PCB board and soldering, giving them the following characteristics:
Robust and Durable: Fully encapsulated in epoxy resin for strong protection.
High Brightness: Up to 8,000–10,000 nits, suitable for outdoor environments.
Excellent Heat Dissipation: Copper-based heat dissipation design ensures stability under high temperatures.
Long Lifespan: Theoretical lifespan of up to 100,000 hours.
SMD is a rapidly developing LED packaging technology that uses miniaturized surface-mount designs, integrating red, green, and blue LED chips into a single支架碗杯. Key features of SMD include:
High Integration: Compact size enables higher pixel density.
Wide Viewing Angle: Horizontal and vertical viewing angles up to 110 degrees.
High Production Efficiency: Suitable for automated SMT production.
Indoor Advantages: Ideal for displays with P2–P10 pixel pitches.
| Feature | DIP Technology | SMD Technology |
|---|---|---|
| Brightness | 8,000–10,000 nits | 5,000–6,000 nits |
| Viewing Angle | ~110° horizontal | 110° horizontal and vertical |
| Protection | IP65+, fully sealed | Requires additional protection |
| Environment | Harsh outdoor conditions | Indoor and some outdoor uses |
| Lifespan | 100,000 hours | Shorter in harsh environments |
| Maintenance Cost | Low (long lifespan) | Relatively higher |
| Pixel Pitch | Minimum P6 | Can achieve below P2 |
Brightness and Visibility
Outdoor LED displays must remain clear under strong light, making brightness a critical metric:
Basic Brightness: At least 5,000 nits (cd/㎡) for standard outdoor scenarios (e.g., urban streets, mall facades).
High-Brightness Environments (e.g., open squares, highways): 8,000–10,000 nits to prevent image washout.
Pixel Pitch (Pitch) and Viewing Distance
Pixel pitch (e.g., P3, P6, P10) directly affects clarity and optimal viewing distance:
Small Pitch (P3–P6): Ideal for close viewing (e.g., store signs, bus stops), with high pixel density.
Medium Pitch (P6–P10): Cost-effective for urban billboards (e.g., P8 screens best viewed from 16–40 meters).
Large Pitch (P10–P31.25): Suitable for long-distance viewing (e.g., building facades, stadium exteriors), low cost but lower clarity.
Protection Rating (IP Rating)
Outdoor screens must withstand rain, dust, and other environmental challenges:
IP65: Dustproof + low-pressure water resistance, suitable for semi-outdoor use (e.g., under eaves).
IP66/IP68: High-pressure water resistance or full waterproofing for fully exposed environments (e.g., squares, highways).
Additional Protection: UV-resistant coatings, anti-corrosion treatments, and low-temperature startup (for regions below -20°C).
Refresh Rate and Dynamic Performance
Basic Requirement: ≥1,920Hz to avoid scan lines during camera capture.
High-End Requirement: ≥3,840Hz (e.g., live sports broadcasts) for smooth motion.
Energy Efficiency and Long-Term Costs
Power Consumption: ~800–1,000W/㎡ for P3 screens; ~300–500W/㎡ for P10 screens, leading to significant long-term cost differences.
Energy-Saving Tech: Dynamic PWM dimming, low-voltage driving.
Lifespan: High-quality LEDs last ≥100,000 hours (~10 years), but high temperatures may shorten this.
Installation and Maintenance Ease
Modular Design: Enables quick assembly/disassembly and front/back maintenance.
Lightweight Construction: Easier hoisting and installation.
Cooling Systems: Built-in fans or heat pipes to prevent overheating.
| Scenario | Recommended Model | Key Metrics |
|---|---|---|
| Urban Commercial Square (100㎡) | P8–P10 | 6,000 nits, IP66, 3,840Hz refresh |
| Highway Billboard (50㎡) | P5–P6 | 7,000 nits, IP65, dynamic content |
| Stadium Mega-Screen | P16–P20 | 8,000 nits, IP68, low power design |
Core Needs of the Outdoor Market
For applications like highway billboards, stadiums, and landmarks, high brightness, long lifespan, and low maintenance costs remain critical—areas where DIP excels. For example, in markets with extreme outdoor conditions (e.g., North America, the Middle East), Kingaurora’s DIP screens are widely trusted for their stability.
Established Technological Moat
With 16 years of DIP expertise, Kingaurora has built patent barriers in lamp bead packaging, heat dissipation, and energy efficiency that competitors can’t easily surpass. For instance, its self-developed DIP570 lamp beads far exceed industry standards in UV resistance, anti-corrosion, and humidity tolerance.
New Opportunities in the Green Trend
As global carbon-reduction policies tighten, Kingaurora’s "high-brightness + truly energy-efficient" DIP solutions have become the top choice for outdoor advertisers, expanding market potential.
Despite DIP’s long history, Kingaurora hasn’t rested on tradition. Instead, it has continuously innovated to enhance energy efficiency, display quality, and maintenance:
"One Square Meter, One kWh per Day" Breakthrough
The Kingaurora A Pro series uses DIP570 lamp beads and efficient power management to save 2 million RMB in electricity over 10 years for a 300㎡ screen. Compared to traditional DIP screens, energy efficiency improves by 30%, debunking the "high brightness = high consumption" myth.
Modular Quick-Release Design: 10-Second Module Replacement
Traditional DIP screens are bulky and hard to repair. Kingaurora’s modular design allows front/back access, enabling 10-second module swaps and slashing maintenance costs.
Supports 3D Effects and Seamless Corners
Through optical optimization, Kingaurora’s DIP screens achieve 3,840Hz refresh rates, 110% NTSC color gamut, and even裸眼3D effects, meeting creative advertising demands.
Kingaurora’s 16-year commitment to DIP stems from real outdoor display needs, constantly refining this classic technology. From high brightness and energy efficiency to ultra-long lifespan and creative displays, DIP has been revitalized under Kingaurora’s stewardship. As smart cities and 3D ads proliferate, DIP technology may yet deliver more surprises.
