admin2024-11-18 14:21:552024-11-20 14:31:47What Does LED Mean? – Latest Definition 2024Whether you are an advertising contractor, a media planning company, or a government purchaser, the space led video wall you design will inevitably encounter problems such as blurred colors and severe image burn-in. After all, finding the right cob or smd product is the key.
As a professional led display manufacturer, our COB600-Series fine pitch led display has a consistent smooth surface, can reach 20000:1 ultra-high contrast ratio and 3,840Hz refresh rate, so it can show high-definition realistic and 4k resolution lossless image quality in your high-precision and interactive environments.
Narrow Pixel Pitch (NPP)
Low Power Consumption
Ultra-wide 4K Resolution Viewing
COB LED Chip 99.99% Process Yield
Water-proof, Dust-proof and Anti-collision
Module Front Maintenance
● Use standard cob module(size: 150X168.75mm, weight: 200g), so it can compatible with different pixel pitches;
● It only takes 3-5 seconds to remove the module from the front using the suction cup, allowing for quick and efficient replacement.
Energy Efficiency
● As use 2.8/3.8V dual-channel separate power supply mode and common cathode technology, cob chip can be energy-saving more than 50%;
● Power consumption is reduced, so cob led board temperature remains lower and keep long service life, improve your return on investment.
Drive 4K Resolution
● Our cob series products all have tight pixel pitch, and high-density means high definition; at the same time, our pixel pitch can be balanced with screen size for optimal resolution without visible gaps;
● Superior pixel pitch can easily reach resolution up to 4K (4096*2160), thereby drives better 4K/8K video sources, capable of live broadcasting of games or conferences.
Ultra-finer Pixel Pitch Model Query
A good led display pixel pitch depends on viewing distance and the amount of detail desired.
Using a simple rule of thumb such as the 10x Rule, multiply the pixel pitch by 10 for the minimum comfortable viewing distance.

● LED Panel Pixel: 384*216
● Pixels Per Sqm: 409,600
LED Chip On Board
● COB approach is chip on board, so that smaller components can be firmly fixed without bonding wires, making the chip density higher;
● COB led panels have good resilience and high black consistency, which can reduce moiré effects, reduce failure rates, achieve 99.99% process yield;
● Compared with surface mount device (SMD) and integrated matrix device (IMD) LED options; COB light scatters evenly, ensuring uniform brightness and avoiding black spots.
Protection Function
● The cob panel is waterproof/moisture-proof (IP54), dustproof, pressure-resistant/collision-proof/super impact-resistant;
● The smoother surface protective layer of the cob circuit board has anti-oxidation treatment, which is effective in preventing electrostatic discharge (ESD) and increasing service life.
COB Vs SMD
● SMD LED is the predecessor of cob led and is currently the industry standard in the display field, used in most lighting and display product elements.
● COB LED is able to densely pack smaller components together with higher resolution, achieving excellent light quality, intensity and uniformity.
Image Video Effects
Our cob led screen can achieve better video display effects, which should be analyzed from different angles, as follows:
Brightness
In order to maintain low light decay/attenuation, the default brightness setting of our cob products is around 600 nits; and with HDR10 support, the light is ensured to be uniform.
Contrast Ratio
The display usually maintains a contrast ratio of 5,000:1, but our cob panel can reach a static contrast ratio of 20,000 and an ultra-high dynamic contrast ratio of 100,000.
Color Gamut
Only a higher color gamut can display richer colors, and the 120% NTSC color gamut ensures the true presentation of the cob led video wall.
Refresh Rate
COB has a 3840-7680Hz refresh rate, which can ensure seamless video display; the faster the continuous image speed, the smoother it looks.
Grayscale
The contrast range of grayscale images is from the weakest black to the strongest white, cob can reach up to 18-bit grayscale with a wider color depth.
Picture Quality
COB led has higher reliability and lossless image quality, which can reproduce lifelike ultra-high-definition images, display realistic colors, and achieve color reproduction.
Ultra-light Aluminum
● Our cob cabinet is made of die-cast ultra-light aluminum, each cabinet weight only 4.5kg, and can be easily moved by one person;
● Standard size(600*337.5mm/aspect ratio 16:9) without screws, faster, safer and more convenient to install, saving your construction time.
Seamless Connection
● CNC high-precision processing (cabinet flatness ≤ 0.1mm) to achieve perfect seamless connection;
● Ultra-quiet fanless design, without complex wiring, takes up less space, allowing you to design your space with ease.
COB Display Disadvantage
● High initial price: New technological revolutions require more costs;
● Complex manufacturing process: Need higher requirements for production equipment, and only considerable scale manufacturer dare to try it;
● Complex maintenance: When there is only one dead light, the entire module needs to be replaced, which requires more spare parts and a longer warranty.
Enhance Performance – Meet Your Visual Needs
Color Enhancement
● Effortlessly creating FHD, 2K, 4K, 8K, and 16K video walls, presenting the most authentic details and brightness levels in any scene;
● Color enhancement technology improves color accuracy and vibrancy, ensuring more vivid and realistic visual with outstanding gradient effects.
Ultra-Wide Viewing Angle
● Our cob display modules have an ultra-wide 170° viewing angle, providing always-clear visuals from any direction;
● At the same time, cob small pitch technology reduces viewing distance, reduces eye fatigue, and enhances the viewing experience.
High-Precision Environments
Relying on high-definition resolution and unparalleled ultimate durability, our COB600-series products are widely used in high-precision environments, such as aerospace, medical imaging, command centers, corporate conference/meeting rooms, TV live studios, etc.,
Interactive Application Environment
COB panel with smooth surface can touch or tap on the display, can be used in interactive education and training; and interactive touchscreens in exhibition halls, museums, galleries, public facilities and high-traffic areas.
Indoor Decoration Advertising
Our cob screen can play indoor advertisement and are used in shopping malls, hotel lobbies, and multi-function halls; they can also transmit traffic information at airports and train stations.
Retail Display Spaces
Our cob products can also be made into digital signage to relevant product information and promotional advertisements, achieve the effect of promoting the brand.
