During our use, in order to better ensure that the LED folding screen can work properly and achieve the expected display effect and performance requirements, in general, the LED folding screen needs to be debugged, so as to better improve the user's viewing experience and meet the needs of various application scenarios. So do you know what are the main steps for debugging LED folding screens? The following Sunrise Technology editor introduces you

Understand product features: Understand the structure, characteristics, technical specifications and performance parameters of the LED folding screen in detail in order to formulate a reasonable debugging plan.

Check hardware connections: Ensure that all hardware connections of the LED folding screen are correct, including power cords, signal cords, etc., and conduct preliminary inspections to ensure that there are no loose or damaged parts.

Power and signal inspection: Check whether the power and signal of the LED folding screen are normal, and ensure that the screen can light up and receive signals normally.

Preliminary display inspection: After the screen is lit, check whether the LED folding screen has abnormal display areas, such as black screen, flower screen, flickering, etc.

Brightness adjustment: The brightness adjustment of the LED folding screen can be carried out by pulse width modulation (PWM) method, which controls the brightness by periodically changing the width of the light pulse. This method is more suitable for digital control.

Adjust the current: Change the current flowing through the LED to change the brightness, but it should be noted that the continuous task current allowed by ordinary LED tubes is generally around 20 mA, so avoid exceeding this range.

Contrast adjustment: Carefully and patiently adjust the contrast of the LED folding screen to ensure that it can present a good viewing effect under various ambient light.

Determination of the reference color: According to the principle of the three primary colors of light (red, green, and blue), determine one of the colors as the reference, and generally choose a color with a lower brightness ratio.

Color adjustment: Use professional color calibration tools to fine-tune the color of the LED folding screen to ensure that the brightness and ratio of each color are in the best state, so as to achieve the purpose of truly restoring the color of the image.

Physical position and angle adjustment: According to actual needs, adjust the physical position and angle of the LED folding screen to obtain the best viewing effect and visual effect.

Run test: Perform a long-term run test on the LED folding screen to check its stability and reliability. At the same time, check the anti-interference ability in a complex electromagnetic environment to ensure that it can work stably.

Split screen and display mode adjustment: For multi-screen spliced LED folding screens, it is also necessary to split the screen, adjust the resolution, adjust the display mode, etc. to ensure that the entire screen can be displayed normally and coordinated.

Debugging record: During the entire debugging process of the LED folding screen, record the operation and results of each step in detail for subsequent analysis and optimization.

Problem feedback: If any problems or abnormalities are found in the LED folding screen, record and feedback to the relevant technicians or manufacturers in time so that they can be solved as soon as possible.

In summary, we can see that the debugging of the LED folding screen is a complex and meticulous process that requires comprehensive consideration of multiple aspects. Only after rigorous debugging and testing can the product performance and viewing effect of the LED folding screen be ensured to be in good condition.
