Manually adjust the white balance of the LED display screen, mainly by adjusting the relevant parameters on the display screen controller, changing the brightness of the three colors of red (R), green (G), and blue (B) to achieve a suitable balance state, thereby presenting accurate white. 

The following are the detailed steps for manually adjusting the white balance of LEDs:

I. Preparation

1. Understand the display screen parameters: First, you need to understand the basic parameters of the LED display screen used, including resolution, pixel pitch, brightness, etc., so that you can make targeted adjustments during the adjustment process.

2. Prepare test tools: Use professional test instruments (such as color analyzers, brightness meters, etc.) to measure the color and brightness of the display screen to ensure the accuracy and scientificity of the adjustment.

II. Enter the adjustment mode

1. Open the control software: Open the control software that matches the LED display screen through a computer or other control device.

2. Enter the adjustment interface: Find the relevant options for white balance adjustment in the control software and enter the adjustment interface.

III. Manual adjustment process

1. Observe the initial state: Before adjustment, observe the initial state of the display screen and record the brightness values ​​of the three colors of red, green, and blue.

2. Individual adjustment:

- Red adjustment: gradually increase or decrease the brightness value of red and observe the changes in white on the display. If white is reddish, you need to reduce the brightness of red; if white is greenish or blue, you need to increase the brightness of red appropriately.

- Green adjustment: Similar to red adjustment, gradually adjust the brightness value of green to balance white.

- Blue adjustment: Similarly, gradually adjust the brightness value of blue to ensure that white is balanced between red, green and blue.

3. Comprehensive adjustment: On the basis of individual adjustment, make comprehensive adjustments to the three colors of red, green and blue. Through repeated observation and adjustment, the white on the display presents the most accurate and natural effect.

IV. Testing and verification

1. Use test instruments: Use professional test instruments to test the color and brightness of the adjusted display to ensure the accuracy and scientificity of the white balance adjustment.

2. Observe the display effect: Observe the display effect of the display under a variety of different display contents and environments to ensure that the display after white balance adjustment can present good color effects in various situations.

V. Precautions

1. Avoid over-adjustment: During the adjustment process, avoid over-adjustment that may cause color distortion or excessive brightness.

2. Save adjustment parameters: After the adjustment is completed, save the adjustment parameters in time so that they can be quickly restored when needed.

3. Regular inspection and maintenance: Regularly check and adjust the white balance of the LED display to ensure that it can maintain a stable color effect during long-term use.

Through the above steps, the white balance of the LED display can be manually adjusted to make it present a more accurate, natural and comfortable visual effect. 

It should be noted that manual adjustment of white balance requires certain professional knowledge and skills, so be careful and meticulous during the operation.
