Patent Description:
Recently, various electronic devices, which are able to be directly put on a human body, have been developed. These electronic devices are generally called "wearable devices".

The wearable device put on a part of the human body may include, for example, a head-mounted display (HMD) put on the head of a user to display an image, smart-glasses, a smart watch (wristband), a contact lens-type device, a ring-type device, a shoe-type device, a clothing-type device, and a glove-type device, and may have various types attachable to a part of the human body or clothes. In particular, the HMD may be provided as goggles or glasses.

As the wearable device is directly put on the human body, the mobility and the accessibility of the user may be improved.

<CIT> discloses an augmented reality display system, including a wear frame, a display module, two perspective type leaded light components and mainboard. The the user can see the true scene in the external world mixed with a 3D virtual scene.

<CIT> discloses a head worn computer including an optical chassis with a rigid open box structure configured to provide a stable optical mounting reference plane and a plurality of image source reference planes. The head worn computer further includes a first image source mounted on one of the image source reference planes to project first image light through a first hole in the optical mounting reference plane and a second image source mounted on a second of the image source reference planes and configured to project second image light through a second hole in the optical mounting reference plane. An outer frame holds the optical chassis such that, when worn by a user, the first and second image light is aligned with the eyes of the user.

<CIT> discloses an optical unit including a liquid crystal display panel, a backlight, a reflecting mirror, a lens and a case which accommodates these elements. The optical unit can also be disposed in front of either of the right and left eyes of the user. A half-mirror which reflects image light emitted from the optical unit toward the eye of the user and transmits light from the background is disposed below the optical unit. By moving the optical unit toward the right or left, the eye, with which the user sees a virtual image, is switched to the other.

<CIT> discloses a head-mounted display device, which comprises a shell and a group of optical system arranged in the shell. The optical system comprises an image display screen, an optical magnifying lens group and a reflecting and transmitting lens, wherein the image display screen is located above the optical magnifying lens group; and the reflecting and transmitting lens is located below the optical magnifying lens group. The optical path of the optical system is that image optical information emitted by the image display screen is transmitted via the optical magnifying lens group and then reflected to a human eye by the reflecting and transmitting lens; and the environment optical information outside the head-mounted display device is transmitted to the human eye via the reflecting and transmitting lens.

<CIT> discloses a method and apparatus of displaying an electronic video image using a head-worn near-to-eye display in a non-immersive fashion, such that the wearer can choose, through simple adjustments of their neck and eye angles, to either look at the displayed video image or their natural environment. Prescription lenses may be incorporated into the optical chain of the near-to-eye display. Motion and position sensors incorporated into the head-worn device are used to automatic stabilization of the video image and to automatically adjust the vertical angle of either the camera or the electronic display or both, by sensing the vertical angular position of the user's head.

<CIT> discloses techniques for recalibration of outward facing cameras supported by a see-through, head mounted, mixed reality display system having a flexible portion between see-through displays for the eyes. Each outward facing camera has a fixed spatial relationship with a respective or corresponding see-through display positioned to be seen through by a respective eye. For front facing cameras, the fixed spatial relationship allows a predetermined mapping between positions on an image sensor of each camera and positions on the respective display. The mapping may be used to register a position of a virtual object to a position of a real object. A change in a first flexible spatial relationship between the outward facing cameras can be automatically detected. A second spatial relationship between the cameras is determined. A registration of a virtual object to a real object may be updated based on the second spatial relationship.

<CIT> discloses a packaged IC device in which a die is sandwiched between first and second substrates such that (i) peripheral electrical contact pads of the die are wire bonded to the first substrate, e.g., for routing functional input/output signals, and (ii) core-area electrical contact pads of the die are connected to the second substrate in a flip-chip arrangement, e.g., for routing one or more power supply voltages to the core area of the die. The second substrate has a shape and position that (i) expose the peripheral electrical contact pads of the die for unencumbered machine-implemented wire bonding during the assembly process, and (ii) enable direct electrical connections between the first and second substrates outside the footprint of the die, e.g., by way of the corresponding solder bumps attached between the two substrates.

<FIG> illustrates the image output module <NUM> and the semi-transparent member <NUM> of the electronic device, according to an embodiment. <FIG> is a view illustrating transmitting visual information output from the light output member <NUM> to the eyeballs of the user, according to an embodiment.

Referring to <FIG> and <FIG>, the image output from the light output member <NUM> of the image output module <NUM> may be transmitted to the semi-transparent member <NUM>. The image output module <NUM> may include the light transmitting member <NUM> that includes one or more lenses and/or mirrors. The one or more lenses and/or mirrors may optically connect the light output member <NUM> with the semi-transparent member <NUM>.

The front surface of the semi-transparent member <NUM> may be formed to be in a convex shape. In addition, the rear surface <NUM> of the semi-transparent member <NUM>, facing the eyeballs of the user, may be formed to be in a concave shape.

The semi-transparent member <NUM> may have semi-transparency and includes a semi-transparent lens. The light output member <NUM> may include a light generating device, such as a display device or a projector, which emits light. The second visual information <NUM> output from the light output member <NUM> is reflected by the semi-transparent member <NUM> and may be transmitted to the eyeballs of the user. In addition, the first visual information <NUM> transmitted through external light may be transmitted to the eyeballs of the user through the semi-transparent member <NUM>.

An image area <NUM>, in which the first visual information <NUM> and the second visual information <NUM>, which are transmitted to the eyeball of the user, may be formed as illustrated in <FIG>. Since the lower portion of the semi-transparent member <NUM> is disposed closer to the eyeball of the user than the upper portion of the semi-transparent member <NUM>, the upper portion of the image area <NUM> may be formed to be wider than the lower portion of the image area <NUM>.

Referring to <FIG>, the camera module <NUM> is arranged to be inclined at a first angle with respect to a vertical line, and the upper and lower portions of the opening <NUM> formed in the front surface of the housing <NUM> or the front cover <NUM> may be asymmetrically formed. The lower portion of the opening <NUM> may be formed to be deeper than the upper portion of the opening <NUM>, and the lower inner sidewall of the opening <NUM> may be formed in an inclined manner so as not to block the field of view of the camera module <NUM>.

The semi-transparent member <NUM> is arranged to be inclined at a second angle with respect to the vertical line. The second angle is formed to be greater than the first angle.

Accordingly, the semi-transparent member <NUM> facing the eyeball of the user of the electronic device <NUM> is positioned under the eyeballs of the user such that the field of view of the user corresponds to the main field of view of a human being. As illustrated in <FIG>, the semi-transparent member <NUM> is arranged to be inclined at a specified angle with respect to the line perpendicular to the front direction.

Additionally or alternatively, the auxiliary processor <NUM> may be adapted to consume less power than the main processor <NUM>, or to be specified to a specified function.
