Abstract: An online memorial device is provided to show the figure in the lifetime of the dead person to a descendent. The life information of a dead person and a memorial message are displayed on an OLED(Organic Light Emitting Diode)(100), and a projector projects the figure in the lifetime of the dead person. A camera(300) projects the guests for the memorial of the dead person. The image projected form the projector and the camera are displayed on a screen. The OLED panel is formed in a memorial tablet shape. A solid state photographing device converts the image information of the guests into an electric signal, and a display device forms an image by modulating the brightness of a light according to the electric image signal.
