Abstract

An electronic device is disclosed. The electronic device comprises: a first display for the left eye of a user; a second display for the right eye of the user, that is spaced apart from the first display in a one direction; frames that hold the first display and the second display and are supported on the user's head; and an optical variable unit capable of varying the optical alignment of the first display or second display. An electronic device according to the present invention may be associated with an artificial intelligence module, robot, augmented reality (AR) device, virtual reality (VR) device, and device related to 5G services.

First claim

What is claimed is:

1. An electronic device comprising:
a first display for the left eye of a user;
a second display for the right eye of the user, that is spaced apart from the first display in a first direction;
a controller that transmits an image to the first display or the second display;
frames that hold the first display and the second display and are supported on the user's head; and
a housing in which the controller is located, wherein the housing is capable of varying an optical alignment of the first display or the second display,
wherein the housing includes an inner housing to which the controller is fixed, an outer housing to which the inner housing is installed, a first direction guide hole formed on a surface of the outer housing to guide the inner housing in a horizontal direction, and a housing protrusion formed on the inner housing and inserted into the first direction guide hole.

2. The electronic device of claim 1 ,
wherein the housing is capable of varying the optical alignment by changing an angle at which the image is transmitted from the controller to the first display or the second display.

3. The electronic device of claim 2 , wherein the controller has a guide lens for transmitting the image to the displays,
the displays each comprising an incidence area positioned close to an end of the guide lens, where the image enters through the guide lens, and a projection area where the image is projected,
wherein the housing changes a relative angle between the guide lens and the displays.

4. The electronic device of claim 3 , wherein the housing changes the relative angle in a second direction that connects from the end of the guide lens to the incidence area and in a third direction that connects from the incidence area to the projection area.

5. The electronic device of claim 1 , wherein the frames are made of elastic material to deform when the user wears the electronic device, the first display or the second display are configured to change position upon deformation of the frames, and the housing corrects error in the optical alignment which occurs as the first display or the second display changes position upon deformation of the frames.

6. The electronic device of claim 1 , further comprising a sensor for detecting an amount of deviation on the first display or the second display.

7. The electronic device of claim 6 ,
wherein the controller determines a degree to which the housing varies through information provided from the sensor.

8. The electronic device of claim 7 , further comprising a driver for driving the housing,
wherein the controller drives the housing through the information provided from the sensor.

9. The electronic device of claim 7 , wherein the sensor detects a pupil of the user, and the controller determines the amount of deviation on the first display or the second display through the information provided from the sensor and thereby determines the degree to which the housing varies.

10. The electronic device of claim 9 , wherein the controller transmits a stored image to the first display or the second display, and the sensor detects the pupil of the user viewing the image.

11. The electronic device of claim 10 , wherein the controller transmits the stored image to the first display or the second display at a focal length approaching infinity, and determines the amount of deviation on the first display or the second display by comparing a focal length of the user determined based on the information provided from the sensor and a preset focal length.

12. The electronic device of claim 8 , wherein the controller shifts an image provided to the first display or the second display by driving the housing.

13. The electronic device of claim 7 , wherein the first display and the second display each have a 3D camera,
wherein the controller gets an image from the 3D camera and creates stereoscopic image-related information.

14. The electronic device of claim 13 , wherein the controller performs image processing by correcting the image from the 3D camera through the information provided from the sensor.

15. The electronic device of claim 14 , wherein the controller determines an amount of deviation on the 3D camera through the information provided from the sensor, and performs image processing by shifting the image from the 3D camera by a number of pixels corresponding to the amount of deviation on the 3D camera.

16. An electronic device comprising:
a first display for the left eye of a user;
a second display for the right eye of the user, that is spaced apart from the first display in a first direction;
frames that hold the first display and the second display and are supported on the user's head;
a first sensor for detecting an amount of deviation on the first display;
a second sensor for detecting an amount of deviation on the second display;
a housing in which the controller is located, wherein the housing is capable of varying an optical alignment of the first display or the second display; and
a controller that transmits an image to the first display or the second display and corrects the optical alignment of the first display or the second display through information provided from the first sensor and the second sensor,
wherein the housing includes an inner housing to which the controller is fixed, an outer housing to which the inner housing is installed, a first direction guide hole formed on a surface of the outer housing to guide the inner housing in a horizontal direction, and a housing protrusion formed on the inner housing and inserted into the first direction guide hole, and
wherein the controller corrects the optical alignment by changing a position of the image displayed on the first display or the second display.

17. The electronic device of claim 16 , wherein the controller transmits a stored image to the first display and the second display, the first and second sensors respectively detect the pupils of the user viewing the image, and the controller determines the amount of deviation on the first display or the second display through the information provided from the sensors and thereby corrects the optical alignment.

18. The electronic device of claim 17 , wherein the controller transmits the stored image to the first display and the second display at a focal length approaching infinity, and determines the amount of deviation on the first display or the second display by comparing a focal length of the user determined based on the information provided from the sensors and a preset focal length.
