Abstract: A rotational information display device capable of connecting a personal computer outputs a connection status of a messenger, the connection with a friend set by the user, a messenger change status of the mail receiver or the content of a personal alarm set or the like as a three dimensional image, a graphic image, a character, an audio signal or the like through the rotational information display device. Therefore, the rotational information display device increases the utilization therefore since a connection status, the connection with a friend set by the user, a messenger change status of the mail receiver or the content of a personal alarm set is identified by using a three dimensional image, a graphic image, a character, an audio signal or the like although the users of the personal computers do not use their computers.

Abstract: The present invention provides a structure of a rotation frame of a rotational information display device which is capable of displaying a 3D image based on an afterimage effect by rotating a light source like a light emitting diode (LED). The rotation frame includes an outer most display unit, an inner most display unit and an intermediate display unit. The outer most display unit is longitudinally formed in an outer most portion from the rotary shaft in a longitudinal direction of the rotary shaft for thereby displaying a certain image in an outer circumferential surface of the image space formed as the light sources are rotated. The inner most display unit is longitudinally formed from the rotary shaft in a longitudinal direction of the rotary shaft for thereby displaying a certain image in a center portion of the image space.

Abstract: The present invention relates to a light emitting diode engaging structure in which it is not needed to use a wire when electrically connecting a controller adapted to control an on and off of a light emitting diode and a light emitting diode in such a manner that the light emitting diodes capable of displaying a 3D information or image in an atmosphere space based on an afterimage effect during a rotation are engaged in a patterned PCB.
