How to Solve the Problem of Different Colors of the Foldable LED Screen?

Nowadays, in many places, the foldable LED screen, with its flexible and versatile scene changes, completes picture switching in an instant while presenting clear images, rich content, and realistic effects, which can bring the audience a great visual experience. However, sometimes, due to various reasons, we may encounter the problem of color inconsistency when using the foldable LED screen. Do you know how to solve this problem? ONUMEN will introduce it for you below:


Change the current flowing through the foldable LED screen

In general, the LED tubes of a foldable LED screen allow continuous working current of about 20 milliamperes, except for the red LED, which has a saturation phenomenon. The brightness of other LEDs is basically proportional to the current passing through them.

Use pulse width modulation method to achieve gray-scale control of the foldable LED screen

We can periodically change the light pulse width of the foldable LED screen (i.e. duty cycle) to achieve gray-scale control. As long as the repeat period of light-up is short enough (i.e. the refresh rate is high enough), the human eye won't feel the flickering of the luminous pixels. Since pulse width modulation is more suitable for digital control, almost all foldable LED screens today use it to control gray levels and solve the problem of color inconsistency.

In conclusion, these are the ways to solve the problem of color inconsistency of foldable LED screens. As long as we find the correct solution, we can easily solve this problem. If you can't solve it, please contact a professional foldable LED screen manufacturer like ONUMEN to seek a solution.
