More Information
Summary:The utility model relates to a DVI-and-VGA compatible synchronous signal processing circuit of plasma panel displays belonging to the technical field of plasma panel displays, which comprises at least a DVI socket that can input DVI-D and DVI-I signals, a decoder that is respectively connected with the clock end and the 2 and 1 ends, 10 and 9 ends, and 18 and 17 ends of the DVI socket, and a four-bus three-state buffer that is connected with the decoder. The decoder is a SIL161B integrated circuit; the four-bus three-state buffer is composed of a 74LV126 integrated circuit and has four inputs. The utility model has the advantages of a simple, practical and effective structure and stable and reliable circuits, which realizes selection of DVI and VGA passages through controlling synchronous signals and can be widely applied to various plasma panel televisions and plasma panel displays.
