Abstract
Abstract A telephone handset incorporates a miniature virtual image display which can display a full page of text at high resolution. The miniature display is a scanning mirror type of display in which a line image is generated by a line of light-emitting devices such as light emitting diodes (LEDs). A magnifying optical system creates a magnified virtual image of the LED line and the virtual line image is then converted into a virtual raster image by an oscillating mirror. The virtual image can be viewed at distances close to the display so that the display can be viewed while the telephone handset is being used.
