摘要
像素亮度的一致性是LED显示屏的重要指标。对于像素亮度一致性不理想的LED显示屏,对其照相获得包含亮度信息的图像文件,再经计算机进行背景去噪、像素定位、亮度信息提取,得到亮度数据文件,最后通过计算及数据库处理,生成Excel亮度校正文件。Excel格式的亮度校正文件,可以方便地送到主流LED显示屏控制器中进行逐点校正,有效地改善LED显示屏的视觉效果。
Consistency of pixel brightness is an important index for LED display.For LED display with un-ideal consistency of pixel brightness,to get pictures file including brightness information by taking photograph,via computer,background can be de-noised,pixel can be positioned,and even information about brightness can be obtained,thus getting file about brightness data,and finally,handled by computer and database,the Excel brightness corrected file will be made.The brightness file corrected in Excel format can be convenient to deliver to the controller of LED display where it will be corrected point by point.In this way,the visual effect of LED display could be greatly improved.
