Abstract
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.
