The present invention relates to an electronic apparatus and display apparatus, and method for driving the apparatuses, and the display apparatus according to an embodiment of the present invention may comprise: a resonance circuit unit for generating voltage by means of inductive electromotive force generated due to an external apparatus; a rectification unit for rectifying the output voltage of the resonance circuit unit; and a converter for outputting the rectified voltage of the rectification unit as the target voltage by varying duty on the basis of duty data and target voltage determined in accordance with the distance from the external apparatus.

Electronic apparatus and display apparatus, and method for operating apparatuses

The present invention relates to a display apparatus and operational method therefor, and an electronic apparatus, and the display apparatus according to an embodiment of the present invention may comprise: a resonance circuit unit for generating voltage by means of inductive electromotive force generated due to an external apparatus; a capacitance variance unit for varying the capacitance (Cv) of the resonance circuit unit in order to control the resonance point thereof, the resonance point having been changed due to the distance from the external apparatus; and a display panel for implementing an image by means of the voltage.

Display apparatus and operational method therefor, and electronic apparatus

Disclosed is a display apparatus including: a wireless power receiver configured to wirelessly receive power from an external power source to supply power to the display apparatus; a display configured to display an image based on a received image signal; communication circuitry configured to communicate with the external module; information acquiring circuitry configured to acquire information about a distance between the display apparatus and a user; and a controller configured to determine consumption power of the display apparatus, to control the communication circuitry to provide information about the determined consumption power to the external module, and to reduce the consumption power of the display apparatus if it is determined based on the acquired information that the user is within a predetermined critical distance of the display apparatus. Thus electromagnetic waves harmful to a human body is controlled to reduce and/or eliminate an affect a user.

Display apparatus and control method thereof

A solder wave height measuring device is provided that may be constructed using a horizontal supporting member that is positioned on a set of conveyors. Perpendicularly attached to the horizontal supporting member is a graduated beam that slidably supports a measuring jacket. The jacket may have a cubic shape, drum shape, or any polyhedron shape, but the jacket will preferably have an upper surface that is perpendicular to the graduated beam to simplify taking visual readings. A surface of the measuring jacket is in contact with the top end of the solder wave to allow the measuring jacket to accurately indicate the height of the solder wave on the graduated beam. Additionally, a fastener can be used to fix the measuring jacket to the graduated beam. The measuring jacket is fixed to the graduated beam by a fastener when the measuring jacket indicates an optimum height to solder at maximum efficiency. This provides an easy and convenient measurement of the solder wave height. Additionally, the apparatus of the present invention is relatively economical due to its low manufacturing cost and simple assembly, the apparatus is easy to operate, few component parts are used, readings can be made visually without requiring operators to bend over into inconvenient positions, the apparatus can be easily maintained in an environment that does not have easy access to high technology components, and the apparatus is easy to operate, repair, and understand by less skilled workers.
