A smart phone is a device that can selectively install various programs for an expanding function of a mobile communication device according to the user's preference and can implement various functions beyond the limit of the passive operations available in conventional mobile communication means have.

The see-through smart glasses are configured to receive data by interfacing with the smart phone through the communication unit 80, or to receive data through a WiFi communication network.

The communication unit 80 receives an RF communication signal or a Bluetooth communication signal according to a signal transmission method and converts the received signal into an electrical signal and transmits the signal to the control unit 50. Alternatively, And is configured to communicate via a communication network or a Wi-Fi communication network to receive data.

Thus, an image based on the data transmitted through the smartphone or the communication network is displayed through the left and right eye views 10 and 12 of the eyeglass unit.

Here, the left and right eye viewing units 10 and 12 may be transparent or semitransparent glass or synthetic resin material, or may be formed of a liquid crystal display unit. The liquid crystal may be controlled so that light is not transmitted or transmitted It is possible.

The control unit 50 generates a control signal for displaying the data received from the receiving unit 80 on the left and right eyes 10 and 12.

A head-mounted display unit 90 for displaying an image on the left and right eyes 10 and 12 is installed on one side of the frame unit 20.

The head-mounted display unit 90 includes a micro-liquid crystal and a light source. The image displayed through the micro-liquid crystal is irradiated to the left and right eyes 10 and 12 and displayed, To be visible.

When an image is displayed on the left and right eye viewing units 10 and 12 through the head mounted display unit 90 and the outside is viewed through the left and right eye viewing units 10 and 12, It is possible to see the actual external environment while viewing the images displayed on the screens 10 and 12. [

Here, if the left and right eye viewing units 10 and 12 are formed of LCD displays, images are displayed on the left and right eye viewing units 10 and 12 through the head-mounted display unit 90 The light transmittance of the portion is controlled to be lower than the light transmittance of the remaining portion.

For the above-described control, the micro-liquid crystal array included in the head-mounted display unit 90 recognizes the array coordinates at which the image is displayed, and the left and right-eye viewing units 10, 12 is controlled so as to lower the light transmittance of the LCD liquid crystal with respect to the liquid crystal position of the LCD.

In addition, Method, a method of detecting a change in capacitance, and the like can be used.

In the present invention, as the proximity sensors 40 and 45, a sensor for detecting whether or not an object is present within a distance range of approximately 1 cm to 20 cm may be used.

Thus, when the face of the wearer of the smart glasses is disposed within the above distance, it is determined that the smart glasses are intended to be worn or worn.

If the detection range of the proximity sensor 40 is excessively wider than 20 cm, it is determined that the face of the wearer is close even if the smart glasses user does not intend to wear the glasses, The detection distance of the proximity sensors 40 and 45 is preferably in the above range.

 The proximity sensors 40 and 45 may be installed at the center of the frame 20 and the glasses leg 30, respectively.

When the proximity sensors 40 and 45 provided at the central portion of the frame portion 20 and the proximity sensors 40 and 45 provided at the center of the frame portion 20 sense that the object is close to the wearer's face, Can be configured to detect more accurately.

When the object is sensed as being disposed within the distance range through the proximity sensors 40 and 45 and when it is detected that the object is not disposed, the magnitude and power of the power supplied through the power supply unit 60 are supplied Elements are controlled to be different.

When it is detected by the proximity sensors 40 and 45 that an object is disposed within the distance, the user determines that the user wants to wear or wear glasses, and the head mounted display 90 and the communication unit 80 And a control unit 50. The power supply unit supplies power to all the components necessary for driving the smart glasses.

However, when it is not detected that an object is disposed within the above-described distance, power is not supplied to the configurations of the head-mounted display unit 90 and the communication unit 80 and the like.

That is, when it is not detected that the object is disposed within the distance range as described above, it is determined that the user does not wear the glasses, and only the limited components such as the controller 50 and the proximity sensors 40 and 45 So that the sleep mode of the smart glasses in which the minimum power is consumed is obtained.

Thus, in the sleep mode, only whether the user's face is located within the distance range, that is, whether the user wears or wets the glasses, is detected, and power is supplied to the components necessary for driving the remaining smart glasses So that the power of the power supply unit 60 can be saved.
