Page 127 Product Specification of 42XGA PDP Module 5. IMAGE STICKING CHARACTERISTICS Image Sticking The fluorescent substance used in the plasma module loses its brightness with the lapse of lighting time. This deterioration in brightness appears to be a difference in brightness in relation to the surroundings, and comes to be recognized as image sticking.
Page 128 Product Specification of 42XGA PDP Module Proposed measures taken to relieve image sticking So long as there is the reduction of brightness in the fluorescent substance, it is impossible to avoid the occurrence of image sticking. Therefore, to relieve image sticking, we offer you a method of entering an image input that may ensure reluctance to the generation of the difference in brightness reduction among the displayed dots.
