Document Type and Number:
WIPO Patent Application WO/2021/006392
Kind Code:
A1
Abstract:
The present invention relates to a mobile terminal device case having an extended display, whereby, in order to solve the problems of increased cost and configuration, inconvenience in use and low compatibility, which occur when providing an extended display, so as to flexibly enhance usability according to whether the extended display is used or not, lower manufacturing costs, and enable the extended display to have versatility so as to be applied to various mobile terminal devices across the board, an assistance device is provided comprising: a terminal device case which has a mobile terminal device seating area formed therein; a detachable foldable cover which, when coupled to the terminal device case, forms at least one rotational shaft at one edge of the terminal device case so as to selectively cover the seating area; a display panel which is mounted on the foldable cover and forms an output area on one surface of the foldable cover; a cover circuit unit which is mounted in the foldable cover and comprises a circuit from the display panel to a cover-side coupling terminal exposed on a surface corresponding to the terminal device case; and a case circuit unit which is mounted in the terminal device case and comprises a terminal device coupling terminal exposed on one location of the terminal device case so as to correspond to a power source and data port of the mobile terminal device from a case-side coupling terminal selectively making contact with the cover-side coupling terminal.
