The ghosting effect detecting method comprises the steps of providing a visual persistency period, providing a maximum color alternation speed of the LCD, obtaining a threshold value by multiplying the human visual persistency period by the maximum color alternation speed, calculating a variation of an intensity level of each of the plurality of pixel components of the LCD and comparing the threshold value and the variation of the intensity level to obtain a comparison result to determine whether the ghosting effect exists in the pixel component."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Detecting and eliminating method for ghosting effect of LCD","description":"Methods for detecting and eliminating a ghosting effect of liquid crystal display (LCD) are disclosed.
