Did you know that a cheap LED display can also deliver a great viewing experience? Not all units and components have to be top of the line to achieve a great viewing experience, and I’m going to walk you through where to make your choice to get a great viewing experience.
How to choose a cheap LED display?
Benefits of choosing a cheap LED display
Choosing cheap LED display can have excellent performance on the basis of cost saving, LED display can realize a seamless and flat display screen through modular design, which can let the audience get a better immersive experience, LED display can use the splicing of LED modules to realize ultra-high resolution pixel screen, so that the audience can have a more excellent viewing experience;
Ultra-high pixel resolution allows LED displays to have a smoother and clearer viewing experience. These advantages of LED display can realize excellent viewing experience as long as you make the right choice from the pitch, performance and control system in sufficient budget.
Point Pitch
The dot pitch is the distance between the LED IC chips on the LED module, the dot pitch affects the pixels, brightness, cost and price of the whole LED display; the smaller the dot pitch, the higher the density of LED pixels, so that you can have a better viewing experience.
The second step in purchasing an evaluation LED display is to determine where it will be used. Cheap LED display usually have a pixel pitch between P3 and P6; if you want to use the LED display both indoors and outdoors, you can choose a pixel pitch around P4, because LED displays around P4 have the high pixel density indoors and high brightness outdoors, which is a best-of-both-worlds choice.
Durability
Choose cheap LED display, in terms of durability may not be very high, the service life is usually in the 30,000 hours to 50,000 hours, a combination of 4 to 5 years of service life, suitable for buyers who want to use for a short period of time; and the higher end of the average service life of the LED display are in the 100,000 hours or more, can continue to provide you with high-quality display services in as long as 13 years.
Refresh Rate
The refresh rate of cheap LED display is not too high, but in fact, the flickering of the display cannot be seen with the naked eye; however, if you use a cell phone or a camera to take a picture of a cheap LED display, you will find that there is a noticeable rippling phenomenon.
In fact, this kind of phenomenon will not bring much impact, because the LED display refresh rate is usually 960Hz, 1920Hz, 3840Hz, and the human eye on the 60Hz refresh rate is very difficult to capture the flicker of the screen; and the higher-end LED display has a higher refresh rate, in the playback of the video can be a clear and smooth viewing experience, and at each time the pause screen can have a clear image display.
Maintainability
In terms of LED display maintenance, there are three common maintenance: before maintenance, front maintenance, before and front maintenance; cheap LED display is usually front maintenance.
Because the price is cheap, the use of cheaper iron cabinet, so usually in the back of the LED display for maintenance, the back of the maintenance needs to carry out a number of screws to fix, in the care of the LED display to be a one of the screws to turn out, this way will be more cumbersome and time-consuming;
The high-end LED display using die-casting aluminum material can be achieved before and after the maintenance of the LED module on the device with a magnetic component, the use of the appropriate tools, only three seconds that can be removed from the LED display in front of the LED module on its maintenance processing, maintenance is good after the same approach can be put back to the original in three seconds, so high-end LED display in the maintenance of a more convenient.
Difference between cheap LED display and high-end LED display
LED lamp bead
LED display bead is one of the important components of the whole display, which determines the brightness, contrast, energy consumption, color accuracy and so on; LED bead has more functions or under the influence of different brands, there will be obvious differences in display effect and price.
Cheap LED display lamp beads and high-end LED display lamp beads in the energy consumption has a great difference, the higher the price of the lamp beads have a higher energy efficiency, while cheap LED lamp beads will consume more electricity;
Every object it has a corresponding service life, and for the LED lamp bead light decay, cheap LED lamp bead will be faster than the high-end lamp bead failure, this is the cheap LED display life is not very long for one of the reasons, lamp bead failure is described as a long time after the use of LED lamp beads will slowly decline in brightness, until extinguished.
Below are some of the most trusted and high quality LED bead brands in the LED display field: Nationstar, Kinglight, RayShine and MLS co.
Video Processor
cheap LED display can choose the appropriate or high quality video processor, LED display video processor is mainly the video or image from external devices after the signal conversion, the formation of the LED display can accept the image size, and will optimize the processing of the video and image, so that the entire LED display has a smoother, clearer display screen;
High-end LED display is usually the use of higher quality video processor, which makes the high-end LED display can also be adjusted through the software brightness, color depth, higher contrast, etc., to enhance the display effect of the whole display experience.
The cheap LED display video processor may not be able to do so prominent display effect, and even sometimes need more than one video processor to carry out the transformation of the screen, not only will consume more costs, but also in the handling of more labor and space occupation.
Control card
LED display control card is one of the core components of the whole LED display, can be responsible for receiving and sending signals, but also can do to store LED display data, act as a storage, etc.; LED display control card can do synchronous control or asynchronous control effect, in the installation of LED display, the use of high-quality control card can be covered to a square meter;
If the cheaper control card is installed inside a square meter, it may need 2~3 control cards to transmit and receive signals, which may require more control card cost and signal line cost. Our common brands of high quality LED control cards are Novastar, Colorlight, Huidu, Linsn and so on.
Driver IC
LED display driver IC is responsible for receiving the signals from the control card and video processor, thus presenting the picture of the LED display, but also control the current and voltage of the whole display, providing constant current for the whole LED display, thus reducing energy consumption;
driver IC also has a certain impact on the refresh rate, high-quality driver IC can effectively remove flicker to improve the viewing experience and reduce screen ghosting, etc.; while the flat IC has a certain impact on the refresh rate, high-quality driver IC can effectively remove flicker to improve the viewing experience and reduce screen ghosting.
The functions of driver IC in the cheap LED display will not be so comprehensive, which is not enough to display excellent images.
Power supply
LED display power supply selection is very important, power supply selection is not good may appear short circuit, fire and other phenomena;
high-quality power supply will have a perfect protection mechanism, such as short circuit protection, current protection, voltage protection, etc., as long as there is anomaly, the LED power supply will cut off the output of the circuit, to protect the components of the LED display will not be damaged and so on.
LED screen cabinet
cheap LED display cabinets are usually made of iron, and high-end LED display using die-cast aluminum, which has a big difference on the surface, iron cabinets will be very bulky and heavy and will take up a lot of space, handling and installation are very inconvenient, and can only be used after the maintenance of the way to repair, more than suitable for stationary LED displays, but iron Cabinet price is very cheap, suitable for buyers with limited budget;
High-end LED display using die-cast aluminum will be more thin cost price will be higher, die-cast aluminum cabinet whether installation, transportation, maintenance and so on are very convenient, usually used in temporary activities at the scene, such as exhibitions, music concerts, large shopping malls billboards.
Choosing cheap LED display or high-end LED display
In short, for some buyers with limited budget, cheap LED display can have a good display effect, if you want to get a better viewing experience, you can then spend some budget to buy higher quality components can be obtained; but for some need to move often or will be transferred to the organization of the LED display, choose the high-end LED display will be more convenient.
