Why Did Kingaurora Persist with DIP in 2025? Unraveling the Mystery
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.
LED Basics: DIP vs. SMD Technology Explained
Before diving into Kingaurora's technological choice, it's essential to understand the two mainstream LED display packaging technologies: DIP and SMD.
What is DIP (Dual In-line Package)?
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.
What is SMD (Surface Mounted Device)?
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.

How to Choose Outdoor LED Displays?
Brightness and VisibilityOutdoor 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 DistancePixel 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.

Why Has Kingaurora Stuck with Outdoor DIP for 16 Years?
Core Needs of the Outdoor MarketFor 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 MoatWith 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 TrendAs 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.
Kingaurora’s DIP Evolution: From "Standard" to "Truly Energy-Efficient"**
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" BreakthroughThe 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.
