What Are The Elements Of The Quality Of The Full Color LED Display?
1. Symptomability and clarity
The main reason for the improvement of the clarity of the LED display is the flatness rather than the clear degree of physics, and the flatness of the flat degree LED display the surface layer of the information screen should be within ± millimeters to ensure that the displayed information image does not distort, part of the protruding or concave fever Going down will cause blind spots in the visible perspective of the display screen. The key and disadvantages of flatness are decided by the production process process.
2. Brightness and angle
The angle of the display screen should handle the problem of light flux consumption. The brightness of the brightness and visual perspective of the indoor full color screen should be above 800cd / m2. In normal work, otherwise the image of the information displayed is not clear because the brightness is too low. The size of the brightness is the advantages and disadvantages of the LED core tube.
3. The clarity of the display cannot be controlled
As a result, the display of the display is not controlled, and the most critical reason is "LED failure". The main cause of LED failure can be divided into two levels: one is that the LED itself is poor in quality; the other is that the operation method is not good. Based on the analysis, we combed the LED failure mode and the corresponding relationship between the two main causes.
4. Energy and energy consumption level
Improving LED special effects and reducing the energy consumption of display screens is a key development prospect of LED display technology. It has the following significance: first, environmental protection, energy saving, energy conservation and emission reduction, and protecting the ecological environment; The capital investment of the equipment; the third is to save water and electricity costs to reduce operating costs; fourth is to reduce the temperature of the display screen; the fifth is to slow down LED attenuation coefficient rates; sixth is to increase reliability indicators; seventh to increase display life; The warm drift of the parameters, the actual effect of the smooth image.
5. Life
The life of the LED display is decided by a variety of factors, because when the display is not at work at the time of work, it will be overloaded at all times. The display screen will be played normally. The life period should be 6 to 10 times of the LED life period. When the LED work, the life span can be longer.
