Nowadays, we can often see cylindrical LED displays in some exhibition halls or halls. How is this cylindrical display made? What are the key points you need to need to consider.
Cylindrical LED display design Key Points：
LED module process: With fine, flat, sturdy, integrated unit design, easy to install, dismantle and maintenance with electricity, the mechanical strength of not less than 70% within 10 years. LED modules support moisture-proof, corrosion-proof, flame-proof, dust-proof, anti-high and low temperature, anti-static, anti-electromagnetic interference, anti-vibration and circuit protection and other functions.
Flexible LED module design: LED module has good material stability, with flame retardant, ultraviolet, oxidation, corrosion, rust and other characteristics. If it is the outdoor screen requires to achieve IP65 or higher protection level, waterproof and prevent moisture from entering.
Good anti-electromagnetic interference: The LED module and the entire system has a very good anti-electromagnetic interference performance, in line with Electromagnetic compatibility standards.
Multi-Interface: The cylinder LED display has audio, video interface and audio, video internal processing to meet the professional broadcasting and television specifications.
independent control: Single point failure does not affect the use of the whole screen, the LED module supports hot swapping with electricity. After replacement LED module, the whole screen display uniformity and consistency.
Independent thermal cycle: The component materials have good thermal conductivity, which can make LED module inside and outside the environment temperature balance, keep stable operation.
Color correction technology: In order to make image color soft and realistic, layered and three-dimensional sense, The cylinder LED display need to support color correction technology, replacement of damaged modules can automatically read the correction data, brightness and color display uniformity and consistency, to achieve true color reproduction, up to the broadcast level of 1024 grayscale.
Loop backup technology: The system adopts stable, mature technology to build, signal transmission – loop backup technology, making the failure rate of signal transmission to geometric base rate.
PMW pulse Technology: The cylinder LED display system adopts constant current source drive control, the driver chip has PMW pulse width modulation function, with 16bit color processing and 10bit grayscale processing capability.
Continuous work: The cylinder LED display works stably and reliably, strong anti-interference ability, continuous work for more than 72 hours. Simple control system software operation interface humanized design, and software upgrade function.
Power distribution system: The cylinder LED display power distribution system has surge protection, short-circuit, disconnection, over-current, over-voltage, under-voltage and leakage protection measures. The power distribution cabinet has the ability of waterproof, rustproof and anti-corrosion; it can automatically alarm when it is opened forcibly. When serious errors occur in the system,it can be automatically shut down and alarm, system operation and reliability.
Cylindrical LED screen customization process
With the advancement of LED technology, people have not only made leaps and bounds in LED display pixel pitch, but also made great progress in materials and splicing styles, so many creative LED displays can be realized.
Since the cylinder of the cylinder LED display is not too wide, the traditional method of artificially bending the LED display is no longer available. At this time, in order to increase the transformation radius, a soft flexible LED display module must be used. Unlike conventional flat modules, flexible soft modules can achieve curvature and bending, so that they can be spliced into curved LED screens, and cylindrical displays are one of the styles.
So what is a soft LED display module? The soft LED module uses a soft material as a substrate to allow the lamp beads to be fixed on it, which can not only achieve a curved shape, but also ensure the stability of the lamp beads. At present, the pixel pitch of the soft LED module can also be very low, such as P1.5, to achieve a clearer effect.
When we design a cylinder LED display screen solution, we mainly calculate the size of the LED module and the LED diaplay dot pitch based on the circumference of the cylinder to achieve precise splicing and ensure the display effect. Therefore, when designing a solution, you need very accurate information.
You need to go to the installation site for investigation, understand the actual on-site conditions, understand the detailed dimensions of the installation location, and then communicate with the end user about the display requirements, including the type of signal source and the routing method, and then configure a detailed product list.
When you want to make a cylindrical LED screen and get around price, please first understand the shape, circumference and height of the cylinder, and then communicate with the end customer about the display content and viewing effect requirements. Therefore, we can determine the pixel pitch of the module.
Since the size of the pixel pitch will directly affect the display effect of the cylindrical LED display screen, the smaller the dot pitch, the clearer the display picture. If using too small pitch will increase the cost. Finally, since the module sizes of each pixel pitch are different, the size of the module should also be considered when using a large pixel pitch.
Since the circumference of the each cylinder LED screen is different, there are few module sizes that completely match the circumference of the cylinder. In order to make the module size consistent with the circumference of the cylinder after splicing, later cutting and other processing are required.
However, to do a successful cylindrical LED screen project, it not only requires choose right modules and pixel pitch sizes, but also involves installation in the later stage.
In general, the cylinder LED module is fixed with an embedded bracket, or a circular bracket is directly built close to the cylinder. Therefore, it is very important to choose a professional customized LED screen manufacturer. Sight LED is a good option. We have a mature process for customizing cylindrical display screens. Because there are often some technical problems when customizing this creative cylindrical LED screen, experience is very important. We can not only make the whole process go smoothly, but also repair it in time when problems arise.
From the cross-section, the soft LED module looks like a trapezoid. At present, the bevel angles of conventional outdoor LED modules are mostly 2° on the left and right. One module is 4°. Therefore, to form a circle with the smallest diameter, at least 360°/4°=90 modules are needed.
| Module Size (mm) | Modules Used | Circumference (mm) | Minimum Diameter (mm) | Approximate Minimum Diameter (rounded to nearest integer) | Main Pixel Pitch Options |
|---|---|---|---|---|---|
| 160mm x 160mm | 90 | 90 * 160 = 14,400 | 14,400 / π | ≈ 4,584 | P10, P8, P5, P4 |
| 192mm x 192mm | 90 | 90 * 192 = 17,280 | 17,280 / π | ≈ 5,500 | P6, P3 |
| 256mm x 128mm | 90 | 90 * 256 = 23,040 | 23,040 / π | ≈ 7,334 | P8, P4 |
| 320mm x 160mm | 90 | 90 * 320 = 28,800 | 28,800 / π | ≈ 9,168 | P10, P8, P5, P4 |
