Abstract

A wearable display system including a display panel to display a signal processed in a predetermined way. The wearable display system includes a grating to diffract a signal output from the display panel, a waveguide to guide the propagation of a signal diffracted by the grating; and a magnifying lens to magnify the signal propagating through the waveguide and to direct the signal toward an eye of a user. The waveguide is formed by a combination of two or more substrates. According to the wearable display system, optical devices are easily and simply arranged on the waveguide to conform to specifications, and furthermore, are individually manufactured and attached to the waveguide. Therefore, the wearable display system is manufactured with minimum time and effort.

Claims

1. A wearable display system comprising:

a display panel to output a signal processed in a predetermined way;

a grating to diffract the signal output from the display panel;

a waveguide to guide a propagation of the signal diffracted by the grating, the waveguide comprising first and second substrates; and

a magnifying lens to magnify the signal propagating through the waveguide.

2. The wearable display system according to claim 1, wherein the signal which is diffracted by the grating into the waveguide is reflected in the waveguide at least two times before reaching the magnifying lens.

3. A method of manufacturing a wearable display system that includes a display panel to display a signal processed in a predetermined way, the method comprising:

forming a first optical device on a first substrate, the first substrate to transmit the signal displayed by the display panel into the first substrate at a predetermined total internal reflection angle;

forming a second optical device on a second substrate, the signal being transmitted into the second substrate from the first substrate at the total internal reflection angle, the second optical device to receive the signal from the second substrate and output the received signal; and

combining the first and second substrates.

4. The wearable display system according to claim 3, wherein the first and second optical devices comprise a grating and a magnifying lens, respectively.

5. The wearable display system according to claim 3, wherein the first optical device comprises the display panel.

6. A binocular wearable display system comprising:

at least one display panel to display a signal processed in a predetermined way;

at least one grating to diffract the signal displayed by the display panel;

a waveguide to guide a propagation of the signal diffracted by the at least one grating, the waveguide comprising first and second substrates; and

at least one magnifying lens to magnify the signal propagating through the waveguide.
