LED显示屏像素定位与标记的一种方法

A method of locating and labeling pixels in the LED panel

在LED显示屏像素点的定位与标记过程中,对逐行标记算法加以改进,在经过逐行扫描2次后,对存在序号间断的标记图像进行第3次扫描标记,以恰当标记像素点在显示屏中的位置.通过失控点的定位与标记实验来验证改进方法的可靠性.

In the process of the locating and labeling pixels in the LED panel, an improved labeling method based on line-by-line scanning algorithm is proposed in order to label and locate the pixels in the panel properly. The third labeling is executed to rearrange the index of the pixels which have been labeled twice by the line-by-line labeling algorithm. The reliability of this labeling method is tested by experiments of locating and labeling some out-of-control points in the panel.
