<P>PROBLEM TO BE SOLVED: To provide a display device assembly capable of changing the convergence angle in an image automatically, even when the speed of moving means changes. <P>SOLUTION: The display device assembly has a display device and a speed measurement device 31 to measure a moving speed of the display device. The display device includes (a) an eyeglass-based frame to be fitted on the head of a viewer, and (b) two image display devices 100 for the right eye and the left eye mounted on the frame 10. Each of the image display devices 100 includes (A) an image formation device 111, (B) an optical system for making light emitted from the image formation device parallel, and (C) an optical device 120 for receiving light emitted from the optical system, guiding and emitting the light. The convergence angle is changed based on a moving speed of the display device measured by the speed measurement device 31. <P>COPYRIGHT: (C)2012,JPO&INPIT |
