P1.56 LED display is currently one of the most sought-after LED displays in the market for commercial purposes. But the question is that how would you choose these displays? The best way is to choose LED displays according to your use case. However, there are some common factors that you must keep in mind before buying the display.

In this guide, you will learn how to choose a perfect P1.56 small pixel light-emitting diode LED screen for your use case. We will try to explain this method in the simplest manner so that even a layman can understand it without any hurdle.

Key Points to Remember When Choosing a P1.56 LED Display

There are various things that should be in your mind before investing in a P1.56 LED display. First of all, it is important to ensure that you need a small pixel display. Remember that small pixel displays are appropriate when viewers will be watching your content from only a few feet away from the screen. If you need the display for places like stadiums, etc. you simply don’t need it. But if you have decided to invest in these displays, here are the key points that you need to follow.

1. Higher Fill Factor

The LED display fill factor (ratio of bright area) is the light-emitting area ratio of every pixel to the screen’s physical surface filled by pixels. LED screens consist of various discreet pixels. There are several things that differentiate pixels. The screen’s black part isn’t illuminated. When you view it at a closer range, you will find an incoherent screen. The graininess you find there is because of the uneven brightness. When the source of light is limited, every single pixel will be much brighter than the entire display screen. Many times, this will create a highly serious slapstick.

According to the light-emitting diode display industry-standard TCO99; the fill factor must not be below fifty percent. Today, most Led screens in the market fulfill this requirement. The low-pass filter’s cut-off characteristics affect the appropriate viewing distance directly of an LED screen with various fill factors. For a Led screen with a similar dot pitch, the screen with a smaller fill factor would have a small attenuation than screens with larger fill factors. So, it will become essential to increase the viewing space.

Remember that fill factor increase results in a wider display screen viewing angle and the effect of color mixing would be more ideal. It will resolve the pixels glare issue and create perfect conditions for appropriately enhancing the screen’s brightness for great results. A P1.56 LED display with a sixty percent fill factor will have reasonable soft brightness, delicate and clear expression, and even bright colors to ensure top quality LED screen display.

2. Color Temperature Adjustments

The color temperature of a screen is a temperature that we determine by making a comparison between the emitter’s emission spectrum shape and the perfectly fitted emission blackbody spectrum. When using the LED screen as the background, its color temperature must be similar to the temperature color we have in that room. It is necessary to ensure adequate color reproduction when viewing. Remember that the lighting depends on your program requirements.

Sometimes, you use low color 3200K temperature lamps and sometimes you use high color 5600K temperature lamps. You must make sure that the LED display must adjust according to the color temperature in the room or area where you will use it. Otherwise, you would not be able to experience great viewing effects.

3. Viewing Distance

When buying a P1.56 LED display, you must make sure that the viewing distance is appropriate. As we already mentioned in this article, the right LED screen viewing distance differs with different LED screen pixels and the fill factors. Four to ten meters is the right space between the LED display and the person so that you can receive a perfect background picture when taking a picture. If you are extremely close, the background would look grainy while taking the picture. So, you have to consider the viewing distance when buying your new small pixel pitch display.

4. Operating Environment

Different LED screens are appropriate for different operating environments. For example, you cannot use an indoor LED screen for outdoor purposes; neither can you use an outdoor LED indoors. Remember that the lifespan of the LED screen depends on the working conditions or environment. LED displays are integrated electronic appliances. They mainly consist of light-emitting diode boards along with electronic parts. The stability and lifespan of these parts depend heavily on the working temperature. When the actual working temperature goes above the recommended temperature, the LED screen will experience a premature failure.

Additionally, you can also not ignore the dust factor. If you need to use your P1.56 LED display in a dusty place, it will affect the working of the unit in the long run. Accumulation of the dust will also cause a hot temperature in components of the LED screen. In extreme cases, it may cause burning. Keep in mind that dust also attracts moisture that may corrode screen circuits, causing short-circuit issues that are too dangerous for LEDs. Therefore, it is essential that you choose the LED screen according to the working environment.

Summary

When choosing a small pixel LED display, you must pay attention to the factors, such as fill factor, temperature adjustments, operating environment, and viewing distance. Small pixel display screens are costly counterparts of traditional LED displays. Therefore, you must make sure that you are investing in the right display screen according to your requirements and actual working environment. Before choosing any P1.56 LED display model, you can conduct online research about the most reliable LED displays available on the market. There, you can easily find the most sought-after LED displays according to different use cases.

The Guide To Small Pixel Pitch LED Display

       1, Packaging technology:

Above P2 led display screen generally uses SMD 1515, 2020, 3528 of the lamp, LED pin shape using J or L package. Side welding pin, welding area will be reflective, ink color effect is poor, it is necessary to increase the mask to improve contrast. The density further increases, the L or J’s encapsulation cannot satisfy the application demand, must adopt the QFN package method. This process is characterized by no lateral welding pins, no reflective welding area, which makes the color rendering effect very good.

In addition, the whole black integrated design molding, the contrast of the picture increased by 50%, showing the effect of the application of the image contrast to the previous display better.

　　2, Mount Technology:

Small pixel pitch LED display of the RGB device location of the small offset will result in the display of the screen is uneven, it is bound to require a higher precision mounting equipment.

　　3, Welding technology:

Reflow soldering temperature rise too fast will lead to uneven wetting, it is bound to cause the device in the wetting imbalance in the process caused by migration. Too much wind cycle can      also cause the displacement of devices. As far as possible to choose more than 12 reflow soldering machine, chain speed, temperature rise, cycle wind as a strict control project, that is, to meet the requirements of welding reliability, but also reduce or avoid the device shift, as far as possible to control the demand range.

Generally, the 2% range of pixel spacing is used as the control value.

       4, Printed circuit board technology:

With the development trend of small pixel pitch LED display, the 4-layer, 6-layer Board is adopted, the printed circuit board will adopt micro-hole and buried hole design, printed circuit graphic wire thin, micro-porous narrow spacing, processing in the mechanical way drilling technology has been unable to meet the requirements,

The rapid development of laser drilling technology will meet the micro-hole processing.

　　5, Printing technology:

Too much, too little solder paste volume and printing offset directly affect the small pixel pitch LED display lamp welding quality. The correct PCB pad design needs to communicate with the manufacturers to implement the design, the screen plate opening size and the correct printing parameters are directly related to the amount of solder paste printing. General 2020RGB devices using 0.1-0.12mm thickness of the electric polishing Laser Steel Network, 1010RGB the following devices recommend the use of 1.0-0.8 thickness of the steel net. The thickness, opening size and the amount of tin increased.

Micro-spacing LED welding quality is closely related to solder paste printing, with thickness detection, SPC analysis and other functions of the printing presses will play an important role in reliability.

　　6, Screen assembly:

Assembly of the finished box needs to be assembled into a screen to display the small screen, video. However, the size tolerance and assembly accumulative tolerance of the box itself can not be neglected in the small pixel pitch LED display assembling effect. The recent device pixel spacing between box and box is too large and too small will result in the display of dark lines, bright line. Dark lines, bright line problem is now small pixel pitch LED display can not be ignored, the need to overcome the difficult problem.

Some of the companies through the Paste 3m tape, box micro adjustment nut Adjustment to achieve the best results.

　　7, Cabinet assembly:

The box is formed by splicing different modules, and the smoothness of the box and the gap between the modules are directly related to the overall effect of the box assembly. Aluminum plate processing box, cast aluminum box is the current application of a wide range of box types, flatness can reach 10 wire. The stitching gap between modules is evaluated by the nearest pixel spacing of the two modules, two pixels too close to the light line, two pixels too far can lead to dark lines.

Before assembling, it is necessary to measure and calculate the assembly seam, then use the relative thickness of the metal sheet as the fixture prior to the assembly.

　　8, System Card selection:

Small pixel pitch LED display light and dark line and uniformity, color difference is led device differences, IC current differences, circuit design layout differences, assembly differences, such as the accumulation of complaints, some system card companies through the software correction can reduce light and dark lines and brightness, chroma uneven. Select High-performance System Card, the micro-spacing LED display brightness, chroma correction, so that the display screen to achieve better brightness and chroma uniformity, achieved a better display effect.
