Therefore, a colored edge and trail appear at edges in direction of a moving object. In order to reduce the disturbing character of such colored edges and trails, a horizontal spatial equalization of the response time of luminous elements having a shorter response time by low-pass filtering a component signal of the video component signals for driving luminous elements having a shorter response time dependent on a horizontal speed of changes of the component signal is recommended to reduce phosphor lag artifacts on display devices. The arrangement for processing video component signals of different color comprises a compensation unit which according to a preferred embodiment is realized by a FIR filter and a horizontal speed correction unit supplied with a horizontal and vertical motion estimation signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Reduction of phosphor lag artifacts on display devices","description":"Luminous elements of the three colors red, green and blue of video display devices have a different response time.
