摘　　要：PDP较LCD有更高的对比度、更快的响应速度,是一种能显示高画质图像的平板显示器。然而出于PDP的发光显示机理所限,在显示动态图像时会不同程度地产生动态假轮廓现象,严重影响了PDP图像显示质量。为了有效解决这个问题,提出一种新型评价动态假轮廓现象的方法,该方法采用帧频频率控制来减少动态假轮廓的出现,同时提出采用最优灰度组合方式的帧频频率控制新型算法,实验验证结果表明,采用该新型方法对比以往的方法能更有效地减少动态假轮廓现象。The plasma-display panel is a type of flat-panel display that can display a high quality image, and has a higher contrast ratio, faster response speed than the LCD. However, for the limit of the PDP＇s light emitting display mechanism, annoying disturbances such as false contour noise occurs when displaying moving images. This noise is called dynamic false contour, it seriously affects the PDP image quality. To effectively solve the problem, this paper put forward a new evaluation method of the dynamic false contour phenomenon, it adopts the frame rate control to reduce dynamic false contour. And presents a new algorithm for calculating optimal grayseale combinations of frame rate control, experiment results show that by using this new method can more effectively reduce the dynamic false contour comparing to previous method.
