Based on the separation technique of address and display, the subfields with higher weight value playing an important role in producing the dynamic false contour are divided into several subfields with lower weight value. The addressing method of accumulation lighting is adopted for the divided subfields. By comparing the gray statistic of input image with the preset gray level thresholds, the operating situation of the dismantled subfield is dynamically determined so as to reduce efficiently the false contour phenomenon without influencing the picture luminance.

该技术基于寻址与显示分离技术，将对产生动态假轮廓起重要作用的权值较大子场拆分为若干个权值较小的子场，并对拆分的子场使用累积发光的寻址方式，利用输入图像灰度统计与预置的灰度阈值比较，动态地确定拆分子场的使用情况，在不影响图像显示亮度的情况下有效地减小了动态假轮廓现象。

A logical extension of the two-position control mode is to provide several—rather than two—intermediate settings of the controller's output.
