实时记录不同环境湿度下的LED显示屏亮度非均匀性测试数据，包括测试样品编号、测试时间、环境湿度/%RH、亮度非均匀性/%等字段。
2.数据预处理：
（1）对采集的数据进行去噪处理，剔除异常值。
（2）将历史采集的数据（包含本次采集）进行聚合，形成数据集X，并针对数据集X中的亮度非均匀性字段，计算出其平均值。
3.计算线性回归斜率a和截距b：
（1）基于数据集X（以环境湿度为自变量、亮度非均匀性为因变量），运用SLOPE函数确定斜率a，运用INTERCEPT函数确定截距b。
（2）斜率a表示单位湿度变化对亮度非均匀性的影响程度，截距b表示基准湿度下显示屏的亮度非均匀性值。
4.结果运用：
（1）计算比例系数k：k=|a/亮度非均匀性平均值|×100%。
（2）若k≥8%，则判定为"高影响"，若3%≤k＜8%，则判定为"中影响"，若k＜3%，则判定为"低影响"。

This dataset focuses on analyzing the impact of ambient humidity on the luminance non-uniformity of indoor LED displays, revealing the quantitative relationship between humidity variations and display luminance consistency, providing critical decision-making support for display manufacturers and operation teams, and possessing significant application value. It is embodied in the following aspects:
1. Optimizing product moisture-proof design: By analyzing the impact of humidity on luminance non-uniformity, manufacturers can selectively optimize their sealing processes and select appropriate moisture-proof materials, thereby improving the display consistency of LED displays in high-humidity environments.
2. Guiding the formulation of environmental control standards: This dataset can be utilized by display installation engineers, operation and maintenance personnel, and quality inspectors, providing data support for their work such as formulating ambient humidity control standards, predicting trends in display quality changes, and optimizing maintenance plans.

1. Data Collection:
Real-time recording of luminance non-uniformity test data of LED displays under different ambient humidity levels, including fields such as test sample number, test time, ambient humidity / %RH, and luminance non-uniformity / %.

2. Data Preprocessing:
(1) Perform denoising processing on the collected data and eliminate outliers.
(2) Aggregate all historically collected data (including the data collected in this test) to form dataset X, and calculate the average value of the luminance non-uniformity field in dataset X.

3. Calculation of Linear Regression Slope a and Intercept b:
(1) Based on dataset X (taking ambient humidity as the independent variable and luminance non-uniformity as the dependent variable), use the SLOPE function to determine the slope a, and use the INTERCEPT function to determine the intercept b.
(2) The slope a represents the degree of influence of unit humidity change on luminance non-uniformity, and the intercept b represents the luminance non-uniformity value of the display under the reference humidity.

4. Result Application:
(1) Calculate the proportional coefficient k: k = |a / average luminance non-uniformity| × 100%.
(2) If k ≥ 8%, it is judged as "high impact"; if 3% ≤ k < 8%, it is judged as "medium impact"; if k < 3%, it is judged as "low impact".
