A good LED display first to adapt to a variety of environment temperature, not the same weather, can be used in a variety of occasions normal use is necessary, and the brightness of the display also need to have a very good visual effect, especially the very big concert, Special effects lighting needs to be particularly good to meet the needs of this situation, but sometimes, we will find the LED display will appear chromatic aberration, then LED display color difference is due to what reason? Again small series warm reminder, cause full color LED display brightness is not the same situation is because the light-emitting element and drive element two factors together effect the result.
light-emitting element is what we call led Light-emitting diode, in the production of light-emitting diode in the process of brightness inconsistency is unavoidable, but manufacturers generally in the production of diodes after the diode will be divided, generally adjacent to the two-stall brightness gap, then the higher the brightness uniformity, However, it will result in low yield and high inventory, so each manufacturer will control the brightness of adjacent two stalls at around 20%.
Driving elements are usually constant current chip, for example, the MBI5026 and so on, a number of chips containing 16 of constant-current drive output, you can use resistors to set the output value of the current, the same chip output error should be controlled within 3%, the same chip output error must be controlled within 6%.
We encounter brightness inconsistent situation, do not worry, we can directly contact the merchant or ask manufacturers to solve.
