How to choose LED wall according to pixel pitch

Pixel pitch is one of the important technical parameters indicators of LED wall screen, what is pixel pitch? How to choose LED wall according to pixel pitch? This is what many friends doubt, the following is the engineer's best answer:
What is pixel pitch?
Pixel pitch is to reflect the pixel density from the two pixel distance, pixel pitch and pixel density is led screen’s physical attribute; Information capacity is the unit of quantity for per unit area pixel pitch’s one-off shows information carrying capacity. The smaller the pixel pitch, the higher the pixel density, the more information capacity for unit area one-off shows, the closer the viewing distance.
How to choose LED wall pixel pitch?
Choose the LED wall pixel pitch, there are two factors:
1. LED wall viewing distance.
Where is the LED wall, and usually how far the people stay to watch it, this is only one important factor for make sure pixel pitch.
Usually there is a formula for the optimal viewing distance= pixel pitch/(0.3~0.8)，this is a roughly range. For example, the pixel pitch 16mm LED wall, the best viewing distance is 20~54 meters, the closer distance, then could distinguish the LED wall’s every pixel pitch, when stay more far, then could not distinguish instead. (what we said is based on normal vision, not including the myopia and hyperopia)
For outdoor LED wall, the close distance, usually use P10 or P12，the more far distance use P16 or P20,for indoor LED wall, usually use P4~P6 is ok the more far distance use P7.62 or P10.
2. LED wall pixel pitch.
For video, the basic format is VCD, 352*288 resolution, DVD format 768*576. So for the video screen, we suggest that the lowest resolution no less than 352*288, so the display effect is good enough. If lower resolution, it also can show, but not up to much better effect.
For single and double color LED wall which mainly show text and images, not require high resolution, according to the actual size, could show the minimum 9 size font, it is up to your text amount.
Therefore, generally choose LED wall, the smaller the pixel pitch, the higher the resolution will be, and the show effect will be clearer. But this also consider the cost and demand, application scope and other factors.

How to Select a High Quality LED Wall Display

With the development of the led displays, many led wall display manufactures appears in a short time. Because of this the display quality are facing with very terrible competition. Some manufactures use bad quality products with very low price to compete with its rivals. It deeply hurt the customers. As a honestly and professional led display manufacture, Dakco always use good material and high technology to make sure the led display’s quality. Now we would like to tell you some factors which influence the displays’ quality. Hope it is useful for you.

1. The led chip quality.
As the most important part of the led displays, led chip’s quality will directly influence the led displays’ quality. Now there are many led chip brand in the market. Among of them, nichia, cotco cree and silan are used most. So if you want to buy a high quality led wall display, You must pay more attention on the led chips selection. Nichia and cotco cree led chip’s quality are very stable, of course the prices are higher than other chips. As silan chip has the best cost performance, it is used the most now in the led display market especially in china. But even the silan chip, they also have some different kinds, especially on different sizes. From 9 mil to 14 mil, the led chip size is bigger, the brightness is higher, the quality is more stable. so the most of important factor for you to select the display is the led chip brand and quality, no matter indoor led display or outdoor led display.
2. The making process.
As the signal led is very easy to broken, so its making process must be very careful. The humidity control and anti-electricity protection are highly request. Now with the development of the technology, many modern machines are used in this process, include the led inserting machine, wave-peak soldering machine, hot air reflow soldering machine and others. However, there are still some manufactures don’t use these machines but hand-working. This factor will influence the led display quality very much. Dakco pay more attention to this detail. Instead of hand-working, Dakco put the machines into all the making process. so our quality is reliable. If available, You’d better to visit the factory first before you buy a led display.
3. The reasonable design.
LED display screen will be used for a long time. it can reach 100000 hours or even more. so it has a high request for the design and material.
The design mainly refers to two parts: one is led module PCB design. another one is the cabinet design. if the PCB design is not reasonable, it will deeply infulence the life time of the led display.Dakco has very strong R&D team. they are very professional in this aspect. so our led modules have a longer life time. Refers to the led cabinet design, it is also very important. if the cabinet design is not good. after one or two years, it will not protect the led display from rain,snow or storm. then your led display will be destoryed very easily. so when you buy a led display, you must to know whether the supplier is professional or not? especially in technology.
4. The high quality parts material.
The high quality material is very important for led display. such as powersupply, led module mask, module cables and so on. These details are all influence the effect of the led displays. Now in the market. Meanwell power supply is the best for the led display. the colorful module signal cables is better than white one. about the led module mask, Dakco use our own design mask. it won't be changed its shape even after a long time.
These are some experience which dakco want to share with all the people who are interested in led displays. Hope they are useful for you.

small pixel led display is not harmful to eyesight

Small pixel led displays are welcome in a number of occasions by people of all ages because of its unique high brightness, wide color gamut, high contrast and other advantages, however, the small pixel led display light to human eye bio-security issues have also to be taken into attention. HSTV find an evidence to tell the small pixel led display is not harmful to eyesight, see as below:

Chinese Institute of Metrology took accordance with the existing international standards, measured the bio-security of a p1.67 led display from both the blue light hazards to retina and the thermal hazards, and took comparison with a plasma TV and a LCD TV.
Test results show that, at the same brightness and white field conditions, although the peak brightness of the led display is higher than the other two samples in blue band, but its narrow band characteristics resulting weighted scored retinal hazard index not higher than plasma TV and LCD TV. The retina bio-security measured data has no significant differences between the three displays, the led display measurement results even better than the other two displays.
Whats should be keep in mind is that any display can cause permanent eye damage if keeping long-term view on the screen, thus, no matter what form of display is used, the audiences should pay attention to eye health and maintain good habits with the eyes. Work and rest combined is the best way to protect their eyesight.

How to Distingusih the LED Display Quality

Led display products is getting more and more popular for modern life, how to distingusih the led display quality? HSTV listed the following methods:

1. Flatness
Surface flatness of the display should be within ± 1mm, so as to ensure the display image is not distorted. Partial raised or recessed will lead to the display viewing angle appears dead. The quality of flatness is determined mainly by the production process.
2. Brightness and viewing angle
Indoor full color screen brightness should be 800cd / m2 or more, outdoor full color screen brightness should be 6000cd / m2 or more, so as to ensure the normal operation of the display, otherwise the displayed image can't be seen due to low brightness.
3. The balance effect
White balance is one of the most important indicators of the display. Red, green and blue color science should take in the ratio of 1: 4.6: 0.16 in this way pure white is possible, if the actual proportion of any deviation occurs, the white balance bias. White balance is mainly determined by the quality of the display control system
4.The color reduction
Color reduction refers to the color display of color reduction. Display height should be consistent with the color of the playback source, so as to ensure realistic images.
5. Have mosaics, dead phenomenon
Mosaic refers to appears on the display lit or normally black small four-square, both modules necrosis, connector quality mainly used for the display, but off.
Dead point is steady appear on the display or normally black single point, how good or bad from the die to determine the dead point.
6. Have color
Color refers to the existence of obvious color difference between adjacent modules, transition colors in module units, the color phenomenon is mainly caused by the control system is poor, the gray level is not high, low scanning frequency caused.

How to get the most out of your LED screen?

           
      Do you concentrate on your LED Screen? If you want to get the most out of your LED screen wall (and your customers), in terms of recognition from the audience, we will help you determine the best approach for creating a new ad.
Here we go with a few tips that might be useful for you (or your designer), when creating the next advertising to be broadcast on your LED screen wall. If you want to get the most out of your LED screen wall (and your customers), in terms of recognition from the audience, we will help you determine the best approach for creating a new ad.
First of all, let's address the ad duration. Some people make the huge mistake of creating 30 to 40 seconds ads. 30 seconds? Your audience is not sitting on a sofa waiting for the next TV show! They are most probably driving by at 45 miles per hour and hopefully they are more focused on the street rather than your LED Screen.Still, they should be able to see the entire ads, from start to end while passing by. So what's the point of creating a wonderful ad, if they can't read the advertiser's PHone number and address at the end because the ad is too long?
From my experience an ad should be a maximum of 10 seconds in length, and rarely 15 seconds.Longer ads are pointless because either your target sees the beginning and not the end, or vice-versa. In both cases, you didn't get the message across, and the audience did not find an interesting message on your LED wall.
Therefore your customer will have no interest in doing it again in the future because they didn't get much in return for their investment.Of course, there are exceptions to the "10 second" rule, such as when LED Screen walls are installed in pedestrian areas where people have more time to watch the LED screen wall. But as I said, those are exceptions and are rare.
