LED display solution and led display cost
With the popularity of LED screens, many customers do not have an accurate understanding of led screen. The pixel pitch and price of the LED screens they need, or feel that the resolution and price is too different from their expectations. Based on this situation, we would like to share with you a specific analysis about how to choose exact pixel pitch price structure of LED screens:
How to confirm led display solution
Choosing the right LED display requires consideration of a number of factors, including resolution, size, brightness, color accuracy, viewing angle, longevity, and of course, budget. Here's a step-by-step guide to help you make the right choice:
1. Determine the purpose of the display
Will the LED display be used indoors or outdoors? Will it be used for advertising, entertainment or information displays? The purpose of your LED display will greatly influence the specifications you need.
Outdoor led display Indoor led display
2. Determining size and resolution
The size of the display you need will depend on its location and the viewing distance. The farther away the average viewer, the larger the screen you’ll need.
Resolution refers to the number of pixels displayed and it is usually described by the terms P1, P2, P3, etc., where 'P' stands for 'pixel' and the number indicates the distance in millimeters between each pixel. A P2 display, for example, has a pixel pitch of 2mm. The lower the number, the higher the resolution, but also the higher the cost.
3. Consider brightness
Brightness (measured in nits) is especially important for outdoor displays or well-lit indoor displays. Outdoor LED screens should be 5000-10000 nits to ensure that the image can be seen even in direct sunlight. Indoor screens typically require 600-1200 nits.
4. Check color accuracy and contrast
A high quality LED display should be able to render accurate colors and deep blacks. Contrast (the difference between the darkest blacks and the brightest whites the screen can render) is also an important factor to consider. The higher the contrast, the better the image quality.
5. Evaluating viewing angle
The viewing angle is the maximum angle at which the monitor can be viewed with acceptable visual performance. A wide viewing angle of 140 degrees or greater is recommended for the average viewer in all positions.
6. Recognizing longevity and warranty
An LED display is a major investment, so you need to make sure it lasts a long time. A good quality LED screen should have a lifespan of 100,000 hours (about 11 years if it runs 24/7). Also consider the warranty period and what it covers.
7. Budgeting
The cost of LED displays varies greatly, depending on their specification and manufacturer. When budgeting, it is important to consider not only the purchase price, but also the installation costs and potential energy costs.
LED display cost
1. Indoor led display and outdoor led display price
One point: Based on same pixel pitch, the cost of indoor LED display is lower than outdoor LED display because it is waterproof and some technical requirements are different.
For indoor use, it means that there is not much direct sunlight interfering with the LED display, so it will have a slightly lower requirement for brightness.
The normal brightness of a general screen is 600-800nits, if you want to achieve high brightness (≥1000nits), you need to change to a higher level of LED beads or PCB design, which also means an increase in cost.
For outdoor LED screens, high brightness is a necessity, especially in direct sunlight areas (brightness must be ≥ 7000nits).
Another important factor in cost variation is the design of the protection level. Outdoor LED display is often affected by the weather, such as light rain, heavy rain, desert sun, etc. In relatively humid areas, the IP65 protection level of the LED display is sufficient.
However, if it is rainy all year round and there is standing water, you need to use IP68 LED screen body. For high temperature places, consider the heat dissipation problem, IP65 outdoor energy-saving LED display will be a good choice.
2. Fixed installation led display and rental led display price
Rental screen are for rental purposes which need to move , repeated disassembly and installation, the cabinet material requirements are high. so it must be lighter, thinner, high stability.
Therefore, it is generally made of expensive die-casting aluminum, which is convenient to install and dismantle at any time.
On the other hand, the rental screen is generally used for stage performances, the picture effect requirements are high.
So the general use of P3.91 LED display, or P4.81mm pixel HD screen, more demanding will be used for smaller pitch P2.976mm P2.604mm. this is also one of the reasons why the price is higher than the fixed screen.
Whereas fixed LED display is stationary and not often moved, it needs long life and high heat dissipation, and the screen sizes are usually varied.
So the material is usually steel and aluminum, which can be customized and heavier than die-cast aluminum, but the price is more economical than die-cast aluminum.
Fixed LED displays are usually used in highways, stations and hotels, due to the long viewing distance, indoor fixed LED displays usually use P6.67mm P5.33 models, and outdoor fixed LED displays use the most P8mm P10mm.
Aluminum outdoor fixed LED displays are the best solution for highly corrosive environments, such as screens on the beach.
3. Other special led display
With the rapid development of LED display, the application range is getting wider and wider, which also promotes the production of some special-purpose LED displays, such as poster led display, Pole led display, Led ball and flexible led display
Main factors affecting LED Screen Cost
1. LED lamp
As the most important raw material of LED display, its influence on the price is divided into pixel, bead size and brand.
LED display pixel is the distance between 2 LED lamp beads, for example, we say P2.5, it means that the distance between the lamp beads is 2.5mm.Usually small pixel models cost more, as the module pitch decreases, the number of lamp beads that can be put on the PCB board is more, and the cost naturally rises.
LED bead size, usually large pitch LED display uses large size LED beads.
SMD1515, SMD1921, SMD2121, SMD 2727, SMD3535 and other numbers refer to the LED bead size. 1921 indicates that the length and width of a bead is 19nm and 21nm respectively. the cost of large beads is a little higher than small beads.
If the module size is 320x160mm with the same type of LEDs but with different pixels, the total number of LED beads (P10) used in one module will be less than the smaller pixel model. This reduces the cost.
The common brands of LED lights in the market today are Kinglight, Nationstar, Hongsheng, Episen, Cree and so on. As we all know, brand = price + quality.
Some have high price but stable performance. Some have low price, but occupy a large market by virtue of cost competitiveness.
2. Driving IC
LED display uses many kinds of IC, but the driver IC accounts for about 90%, so here we mainly discuss the impact of the driver IC on the price.
Driver IC, mainly to drive and manage the LED, LED is a light-emitting diode, when the number of diodes or tube power consumption is large, it needs to be driven, the drive mode has several levels, in the integrated electronic chip, this chip is called driver IC.
That is to say, it plays the role of providing compensation current to the LED
The impact of IC on the price is mainly reflected in the function of the IC, a good driver IC can provide a constant current source to ensure that the LED display is driven stably to eliminate flickering phenomenon, to obtain high-quality display effect.
Such as some special IC design has LED error detection, power gain control, power correction and other special functions.
In short, the higher the number of ICs, the more features, the higher the price.
3. PCB
FR-4 fiberglass circuit board and copper clad laminate(CCL for short)) are both the material of PCB board.
FR-4 fiberglass circuit board is a traditional electronic PCB board, which has a wide range of applications due to its good insulation, corrosion resistance, compression resistance, and multiple layer printing.
Compared to FR-4 fiberglass circuit board, the LED aluminum substrate use aluminum-based materials, and its thermal conductivity is much better than traditional FR4 fiberglass circuit board.
LED aluminum substrate is a kind of printed circuit board, which is printed on the aluminum plane with good thermal conductivity, and then the components are soldered on it.
Layers of PCB boards:
We have single layer boards, up to four layer boards, and even multilayer boards for indoor LED display modules and outdoor LED screen modules. For single layer boards, this single board needs to support all the components such as ICs, lamps, capacitors and resistors to work properly. If any small problem occurs, this single board will be damaged, which leads to increased failure rate. For double layer board or multilayer board, there are many layers to support the working parts and even if some problems occur, another layer can still support the module to work properly. It reduces the failure rate. But the more the number of layers. The more complex the process is, the more expensive it is.
4. Power supply
The power supply is mainly used to provide the necessary working current for the LED display to ensure the normal operation of the screen. The international universal voltage is 110v or 220v, but the working voltage of each LED display module is 5v, so we need a power supply that can convert 110v or 220v voltage to 5v voltage. We usually use 3 to 4 power supplies per square meter of LED display. At the same time, the higher the power consumption of the LED display, the more power supplies are required, and the price will increase accordingly.
The power consumption of the LED display screen is divided into maximum power consumption and average power consumption.
The maximum power consumption is the power consumption under extreme conditions such as start up or full lighting, and the maximum power consumption is a factor that must be considered when AC power is supplied (wire diameter, switch, etc).
Average power consumption is also called working power, which is the actual power consumption of the display screen.
There are so many power supply on the market, but do you know how to choose it? We suggest that choose them according to the brand. The main brand on the LED display market are Meanwell, ChuangLian, G-energy, Rongdian and so on.
5. Led cabinet
The cabinet material is another factor that affects the price. Now, let us introduce you to the following four common LED display cabinet materials: steel, aluminum, magnesium alloy, and die-cast aluminum. The biggest difference between these four materials is the density of the material, which determines the weight of the cabinet. Steel is 7.8g/cm³, aluminum is 2.7g/cm³, magnesium alloy is 1.8g/cm, and die-cast aluminum is 2.7-2.84g/cm³. Share some information with you:
6. Controller system and package
Control system: The choosing of the control system (such as sending card, receiving card, even video processor and so on) depends on the specific size of your screen and control way (such as by computer or Wifi/4G). Generally speaking, the larger the screen, the higher the configuration requirements and the greater the cost.
Carton packing (Module or accessories); Plywood case packing (Fixed); Flight case packing (Rental). Different packaging, different costs, you can choose the corresponding packaging method according to your demand.
7. Quality Control & Tech Support & After-Sales Service
We guess that many customers have encountered irresponsible suppliers: either the product quality is problematic, or technical support is not provided, or it is a one-time transaction and there is no after-sales service at all.
These things are telling you: quality control, technical support and after-sales service are often more important than the price you think. So don’t lose these virtual value-added services just because of a little price difference.
