TECHNICAL FIELD

The present invention relates to an electronic device using an augmented reality, and more particularly, to an electronic device capable of selectively driving a monocular mode and a binocular mode using one display module.

BACKGROUND ART

An augmented reality (AR) is a technology that displays virtual objects overlapped with images and backgrounds of a reality. Unlike a virtual reality (VR) technology, in which objects, backgrounds, and environments are all made up of virtual images, the augmented reality technology mixes virtual objects in a real environment to provide additional information that a user feels more realistic in the real environment. For example, when the user goes along a road and shines around with a camera of a digital device, the user may be provided with building information and road information included in a screen collected by the camera. Such an augmented reality technology has recently attracted more attention as the supply of portable devices and wearable devices (for example, glasses, etc.) has spread.

The electronic device using the augmented reality in the related art, in particular, glasses are configured in any one structure of a monocular structure or a binocular structure.

Here, the monocular structure refers to a structure in which one display module is fixed to either a left side or a right side of the glasses to implement the augmented reality through either one of a left eye lens and a right eye lens and the binocular structure refers to a structure in which two display modules are fixed to the left and right sides of the glasses, respectively to implement the augmented reality through the left eye lens and the right eye lens.

Accordingly, glasses having the binocular structure has a problem in that a length of a printed circuit board (PCB) for driving the display module increases horizontally and the display module is added, and as a result, a weight of an electronic device increases and current consumption increases as compared with the glasses having the monocular structure.

In addition, the glasses having the monocular structure cannot operate in the binocular structure and the glasses having the binocular structure cannot operate in the monocular structure.

In addition, the glasses having the monocular structure should be designed as each of a left eye type and a right eye type for those with discomfort in one eye.

In addition, in the glasses in the related art, there is a problem in that a monocular/binocular cannot be changed by reflecting a requirement value of a user in a content viewing environment requiring a 3D effect or a screen (a use environment requiring multiple monitors, such as Powerpoint, Excel, drawings, etc.) having a wide field of view (FOV).

DISCLOSURE

Technical Problem

In order to solve such a problem and an embodiment of the present invention provides an electronic device using an augmented reality, which can be used selectively in any one mode of a monocular mode and a binocular mode by using one display module to reduce current consumption and reduce a weight, and to be used for a long time.

Another embodiment of the present invention provides an electronic device using an augmented reality, which is capable of reflecting a requirement value of a user in a screen having a wide field of view, etc., by increasing an aspect ratio when being driven in the monocular mode as compared with a case of being driven in the binocular mode.

Technical Solution

According to an aspect of the present invention, an electronic device using an augmented reality includes: a glasses body including a left eye lens and a right eye lens and a nose support part positioned between the left and right lenses; one display module positioned at the nose support part; an optical system including a left eye optical system transferring a screen displayed on a display provided in the display module and to the left eye lens and a right eye optical system transferring the screen to the right eye lens; and a control unit controlling the screen displayed on the display so as to display the screen on at least one lens of the two lenses.

The display may have an aspect ratio of m*n.

In this case, the control unit may simultaneously display on the display two screens divided at an aspect ratio of (m/2)*n in a binocular mode.

In addition, the control unit may display on the display only any one screen of two screens divided at the aspect ratio of (m/2)*n in a monocular mode.

According to the electronic device having such a configuration, since the binocular mode and the monocular mode may be selectively implemented only by one display module, a weight of the electronic device may be reduced, a size of the printed circuit board for controlling the display module may be reduced, and current consumption may be reduced as compared with the related art in which two display modules are disposed at both sides of the glasses in order to implement the binocular mode, thereby increasing a use time of a battery as compared with the related art.

According to another aspect of the present invention, the electronic device may further include a location adjustment unit adjusting relative locations of the display module and the optical system and the monocular mode and the binocular mode may be selected by using the location adjustment unit.

As an example, the control unit may simultaneously display on the display two screens divided at the aspect ratio of (m/2)*n in the binocular mode.

In this case, one screen of the two screens may be displayed on the left eye lens through the left eye optical system and the other one screen of the two screens may be displayed on the right eye lens through the right eye optical system.

In addition, the control units displays on the display one screen having the aspect ratio of m*n in the monocular mode.

In this case, due to the increased aspect ratio compared to the monocular mode in the related art, it is possible to utilize dual monitors when using a computer and the requirement value of the user may be reflected in a screen having a wide field of view (Powerpoint, Excel, drawing, etc.).

Centers of the nose support part, the display module and the optical system may coincide with each other in the binocular mode, and any one center selected from the center of the display module or the center of the optical system may be positioned to be shifted from the center of the nose support part in the monocular mode.

The location adjustment unit may include any one rail structure selected from a rail structure using a gear, the rail structure using a hydraulic system, or the rail structure using a solenoid.

The electronic device may further include a tracking sensor sensing movement of a pupil of a user and the control unit may control the screen displayed on the display according to a signal from the tracking sensor.

Advantageous Effects

According to the present invention, an electronic device can be used selectively in any one of a monocular mode and a binocular mode by using one display module.

Therefore, current consumption of the electronic device can be reduced, a weight can be reduced, and a use time of a battery can be increased.

In addition, in a case where the electronic device is driven in the monocular mode, an aspect ratio of a screen displayed on any one lens can be increased as compared with a case where the electronic device is driven in the binocular mode, so that a requirement value of a user can be reflected in a screen having a wide field of view, etc.
