We Tepixel is a professional creative LED Display manufacturer that offer fully customized led display solutions from scratch. When it comes to the LED Display, there are many questions that customer want to know, and Price is the most asked question. There are many factors that would affect the price of the LED Display, Below are Key Price-impacting factors, and after you read this article, you would know why even with the same specs, LED display’s price still varies differently.
Below is a study from Trendforce with LED Display’s cost break down. It can be divided into 5 parts, LED lamp, Driver IC, PCB, Power/cabinet/controller and SMT/Molding/Assembly.
What Pixel pitch do you need?
Pixel pitch is the distance between the adjacent pixels, Within the same size, the smaller the pixel pitch, the higher the resolution and more led lamps and ICs would be used. More led lamps and ICs means more cost. Below you can see a chart showing different led lamp qty and IC qty under different pixel pitch.
So how do you know what pixel pitch do you need? To answer this question, normally we would ask the customer what’s the shortest viewing distance from the led display to the audiences? Our eyes have a distinguish ability that after a certain distance we are not able to notice individual pixels. And we define that distance the minimum optimal viewing distance, from our experience the formula would be as below:
Pixel pitch (mm) = minimum optimal viewing distance (m)*0.8
What led lamp brand do you want?
As led lamp takes up the biggest portion in the cost of led display, hence a small price change of the led lamp would affect the end price greatly. There are many different led lamp brands in the market, and the price difference sometime is huge. Many customer would be curious that does high price led lamp brand means better quality? Yeah, higher price led lamp do have a better quality, while this quality here has two aspects 1: visual effect, 2:durability. Actually most led lamp brand’s durability are similar ( though we do offer higher price led lamp solution longer warranty than normal led lamps), The biggest difference lies in the visual effect, higher price led lamp has better color consistence (red, green, blue), they use better materials, for example, for the SMD led lamp, it has copper base, and iron base. Normally the normal led lamp brand is iron base. From the price Wise, you can see the brand rank as below: ( there are also other brands as well, but the one list here are the most common ones)
Nichia >Muti-color>Nationstar>Kinglight=sinyopto>topstar>ruisheng>MLS>Huaxing
And for our Tepixel, we normally suggest customer to use at least Kinglight, and we normally use Nationstar and Kinglight.
What IC brand do you need?
IC is the most import component that determine the led display’s visual effect, like the led lamp, the durability of different IC brands are similar, while the biggest difference lies in the visual effect. Low price IC would easily to have color shifting, or inconsistent color, or nonlinear in greyscale, or bad low greyscale performance the list goes on and on. Even with the same specs, for example 3840hz refresh rate or 7680Hz refresh rate. Good IC’s price can be easily 5th times the price of the lower price ICs. We tepixel always want to provide our customer with good visual effect product, hence normally we use Chipone’s IC.
From the price Wise, you can see the IC brand rank as below:
Marcblock>Chipone>Sum=FM>CFD
Chipone is the biggest led display manufacturer, would suggest to use Chipone’s IC.
What PSU brand do you need?
Power supplier Unit is the key component to make the led display reliable and steady. As from most of our experience, most failure parts of the led display is the PSU. And the price of different PSU also varies greatly. For Some brand, the cost of 1pcs PSU can even buy 10pcs of other brand PSU with the same wattage output. Of course the quality is also totally different. And the PSU is also the key component that determine where it can be used. From the price Wise, you can see the PSU brand rank as below:
Meanwell > HWAWAN > GoldPower > Megmeet > Xingxiu=Chuanglian=Rongdian>G-Energy.
Normally we would suggest as lest to Use Xingxiu level PSU.
Do you need GOB treatment?
GOB means glue on board. LED display is consisted by LED lamp, and LED lamp is soldering on the PCB, when there is a scratch, the led lamp would come off the PCB, hence for pixel pitch over 1.9mm, you would see it has a mask between the led lamps. While when pixel pitch below 1.9mm, it does not have enough room to place mask to protect the led lamp. And when pixel pitch below 1.9mm, it also means the led lamp’s package size is smaller, so does the soldering pad which also means it has smaller attach force on the PCB and easier to come off the PCB.
Then GOB technology comes to market. It applies a layer on glue to fully cover the led lamp and PCB, which protect the led lamp. You can have more detail in this article: https://tepixel.com/gob-led-display/
Many other factors would affect the price of the led display too, especially for customized version.
At Tepixel, we not only produce high quality led displays, but also offer appropriate suggestions based on the requirements of your project. What’s more, we would also side by side help you with your project. If you have any questions, welcome to contact us
