Title:
ELECTRONIC DEVICE INCLUDING VARIABLE CAPACITOR INCLUDING PHOTO-CONDUCTIVE MATERIAL AND METHOD FOR CONTROLLING THE SAME
Document Type and Number:
WIPO Patent Application WO/2020/017877
Kind Code:
A1
Abstract:
An electronic device is provided. The electronic device includes a first conductive layer, a second conductive layer that is formed to be opposite to the first conductive layer. The second conductive layer includes conductors that are electrically separated, and one or more photo-conductive members connected between the conductors. The electronic device further includes an insulating layer that is interposed between the first conductive layer and the second conductive layer, one or more light sources positioned to face the one or more photo-conductive members, and a control circuit. The control circuit outputs a specified light through the light source such that an electric conductivity of the photo-conductive member increases in response to a light, from among the photo-conductive members and some conductors are electrically connected with the photo-conductive member, and a capacitance value between the first conductive layer and the second conductive layer is changed.
