基于校正系统的LED显示屏亮度均匀性评估方法

LED显示屏均匀性,是显示屏图像质量评价中的一个重要指标。文中首先分析了现有基于亮度测量仪器的均匀性评估方法,指出该方法的不足;在LED显示屏亮度校正系统的基础上,对校正系统测量得到的亮度值进行分析处理,提出了以亮度校正系统为基础的LED显示屏亮度均匀性评估方法。该方法能够快捷、客观、全面地得到LED显示屏亮度数据,可以有效评估LED显示屏亮度均匀性。

Luminance Uniformity Evaluation for the LED Display Panel Based on the Correction System

Luminance uniformity evaluation for the LED display panel is an important parameter for image quality evaluation.This paper analyzes existing uniformity evaluation methods based on luminance measure devices,points out their shortages,analyzes and processes the luminance which is obtained from the correction system,and presents luminance uniformity evaluation for the LED display panel based on the correction system.This method can obtain the luminance data of the LED display panel quickly,fully and objectively.It also can evaluate luminance of the LED display panel validly.
