Definitions
- a magnet is necessary for opening and closing, but it is not suitable for being used as a privacy camera cover due to the risk of loss and difficult opening.
- the camera cover as installed on the terminal has a narrow width of the design that can be selected according to the user's taste, and once attached and fixed on the surface with an adhesive, it is not easy to detach.
- the attachment portion of the camera cover is easily detachable on the surface where the camera is formed, it is closed when the camera is not used to prevent invasion of privacy in real time, and the camera can be easily used when necessary.
- the present invention has been made to solve the above-mentioned problems, and provided with a smart glass in the terminal camera, such as a notebook, and processing the operation to supply or cut off the power supply to the smart glass as necessary, whether or not to use the camera function Therefore, there is no need to attach and detach, and in the case of a micro camera, there is no difficulty of repeatedly attaching and detaching, and the purpose is to provide a camera blind using a convenient smart glass.
- the smart glass is characterized in that the polymer dispersed liquid crystal (PDLC) or suspended particle devices (SPD).
- PDLC polymer dispersed liquid crystal
- SPD suspended particle devices
- the terminal camera such as a notebook is provided with a smart glass, and if necessary, the operation to supply or cut off the power supply to the smart glass to be attached or detached according to the use or not of the camera function
- the terminal camera such as a notebook
- the operation to supply or cut off the power supply to the smart glass to be attached or detached according to the use or not of the camera function There is no hassle, and in the case of a micro camera, it is convenient because there is no difficulty to repeatedly attach and detach.
- the smart glass 190 is opaque or semi-transparent or transparent by adjusting the light transmittance and reflectance according to the DC square wave (AC) applied voltage.
- AC DC square wave
- the light is changed into a transparent state depending on whether power is supplied.
- SW2 smart glass switch
- FIG. 3 is a circuit diagram of a camera blind according to an embodiment of the present invention.
- the camera 300 When power is supplied to the notebook OS, the camera 300 operates, and when the camera 300 operates, the light emitting diode LED is turned on.
- the user visually confirms that the light emitting diode LED is turned on and knows that the camera 300 is operating.
- the BAT 110 power is supplied to the notebook OS 100 so that the camera 300 operates and the light emitting diode LED is turned on.
- the MCU 140 is driven to detect the operation signal of the camera 300 to confirm that the camera is operating, and to control the operation of the power-up switch 170 and the phase generator 150.
- the power boosting switching unit boosts the reference DC power supply of the power supply unit 130 to, for example, DC 120V, and the phase generator 150 generates a phase at 60 Hz intervals to switch the DC 120V power at 60 Hz intervals. / AC output to the inverter (160).
