How to choose SMD Outdoor Full Color LED Display Modules
SMD Outdoor Full Color LED Display Modules is a very popular display screen type, not only has a flexible installation size, while the weight and traditional products compared to a great improvement, and the color is more clear and full, can let everyone See more pleasing video screen. So to buy the best quality SMD Outdoor Full Color LED Display Modules should pay attention to which several points to buy it? SMD Outdoor Full Color LED Display Modules of the main points are as follows:
First, look at the flatness of the screen
In order to ensure that the display image will not be distorted, then the surface smoothness of the SMD Outdoor Full Color LED Display Modules must be kept within ± 1mm. If this requirement is not reached and the local bumps will cause SMD Outdoor Full Color LED Display Modules There is a deadline in viewing video when playing video. Therefore, it can be said that flatness is a major factor in determining the quality SMD Outdoor Full Color LED Display Modules.
Second, look at the brightness of the screen
Under normal circumstances SMD Outdoor Full Color LED Display Modules brightness should reach 1500cd / m2 above just to ensure that the normal display work, or because the brightness is not enough so that we can not see the playback of the image content. So in order to buy a good display SMD Outdoor Full Color LED Display Modules depends on the quality of its LED lamp beads and its brightness parameters.
Third, look at the screen white balance
Red and green these three primary colors ratio is 1: 4.6: 0.16 when the screen will show the most pure white, so if the SMD Outdoor Full Color LED Display Modules manufacturers produced by the display in the proportion of the primary color slightly offset Will lead to white balance deviation, resulting in SMD Outdoor Full Color LED Display Modules display quality is affected, so look at the purchase of white balance is also very important.
In today's society, the rapid development of the case, SMD Outdoor Full Color LED Display Modules applications will be more and more widely, but the quality of uneven, leading to frequent accidents, then how do we judge SMD Outdoor Full Color LED Display Modules good or bad The following Xiaobian to give you a detailed description of the knowledge on this area, we hope to be helpful.
 In the SMD Outdoor Full Color LED Display Modules, the most important thing is the LED lamp beads, the lamp beads is good or bad is the impact of SMD Outdoor Full Color LED Display Modules quality. LED lamp beads is the most used in the full color screen machine the most important device, each square meter will use thousands to tens of thousands of lamp beads, lamp beads is also the decision of the whole screen optical display performance of the main, directly affect the audience's evaluation of the display , Lamp beads in the overall cost of the display is also the largest proportion, ranging from 30% to 70%. The importance is immediately highlighted.
So how to identify SMD Outdoor Full Color LED Display Modules?
One, look at the chip and chip size
Chip is the quality of the lamp beads is the decisive factor, under normal circumstances the greater the stability of the chip, the higher the brightness, the better the heat. This is the most important, because the chip directly determines the SMD Outdoor Full Color LED Display Modules color rendering index, brightness, anti-attenuation degree.
Second, look at glue and phosphor
Generally good products will be imported glue, SMD Outdoor Full Color LED Display Modules the package of the lamp beads by hand without deformation, low-quality glue will be a deformation or even cracking and so on.
Third, look at the bracket
In general, the stent for silver-plated copper brackets, silver plated copper bracket is the advantage of rapid heat dissipation, can better cool the lamp beads, resistance is small. SMD Outdoor Full Color LED Display Modules Some businesses on the market will use ceramic brackets instead of silver-plated copper brackets, ceramic stent thermal conductivity is excellent
Four, see the brightness
Is usually what you said your lamp beads can achieve how much LM (lumens), LM (lumens) is a measure of the brightness of the lamp unit
Five, to see whether the uniform color is consistent
The quality of the good light beads light is very uniform, the same color. Poor quality of the lamp beads will appear a lamp beads bright, a lamp beads dark phenomenon, SMD Outdoor Full Color LED Display Modules luminous color mess is not uniform, there will be a clear dark area.
Six, look at the packaging process
Good quality LED lamp beads uniform color, SMD Outdoor Full Color LED Display Modules colloidal consistency is good. This is inseparable from a good machine equipment, production machinery and equipment is a key factor, good equipment can ensure that the product in the various procedures on the stability and consistency, to protect the product yield.
