1. A miniature display apparatus comprising:
- a light source for emitting light, composed of a plurality of light emitting elements arrayed in one dimension;
a vibration mirror, disposed in a position opposite to said light source, for obtaining a two-dimensional virtual image of the light emitted from said light source;
means operatively connected to said light source and vibration mirror for driving said light source to emit light and driving said vibration mirror to vibrate;
position detecting means for continuously detecting the position of the vibration mirror;
means for controlling the driving of the light emitting elements of the light source based on data to be displayed in synchronization with the continuously detected position of the vibration mirror; and
optical means for magnifying and displaying the two-dimensional virtual image obtained by said vibration mirror from said light emitted from said plurality of light emitting elements arrayed in one dimension;
wherein said optical means is disposed between the vibration mirror and an observation position for observing said two-dimensional virtual image, and the position of the two-dimensional virtual image is situated at the focal position of said optical means.

Abstract
A miniature display device formed in such a manner that a magnification lens is disposed between the vibration mirror and the observation position. Further light emitting elements are situated at the focus position of the magnification lens. Thus, a miniature display device is formed which is appropriate for use in a small-sized electronic apparatus such as a hand-held mini-computer.

13. A method of displaying an image on a miniature display device, comprising the steps of:
-
a) emitting light corresponding to an image to be displayed from a one-dimensional array of light emitting elements; b) reflecting the emitted light by utilizing a vibration mirror; c) storing image data corresponding to the image to be displayed; d) driving the vibration mirror to vibrate so as to obtain a two-dimensional image reflected by the vibration mirror from the one-dimensional array of light emitting elements; e) detecting, continuously, the position of the vibration mirror; f) driving the light emitting elements to emit light in response to the stored image data; g) magnifying and displaying a two-dimensional image corresponding to the data stored in memory; and h) synchronizing the driving of the vibration mirror and the driving of the light emitting elements based on data signals corresponding to the stored image data and the continuously detected position of the vibration mirror, to thereby display a two-dimensional image corresponding to data stored in memory by use of the one-dimensional array of light emitting elements.
