Abstract: A display device includes a light emitting sub-pixel disposed in a display area, a light receiving pixel disposed in one of the display area or a non-display area, and a touch sensing layer including a sensing conductive layer overlapping with the light receiving pixel.

Abstract: A method of driving an electronic device includes displaying a plurality of fingerprint recognition icons on a display device configured to perform fingerprint recognition, and releasing a lock state of the display device through a fingerprint authentication process upon determining at least one first fingerprint recognition icon among the plurality of fingerprint recognition icons is touched. The plurality of fingerprint recognition icons include at least one first fingerprint recognition icon configured to support the fingerprint recognition and at least one second fingerprint recognition icon configured to not support the fingerprint recognition.

Abstract: Disclosed are a deionization electrode having ion adsorption layers and ion selective membranes formed at opposite ends thereof, an electrode module configured such that deionization electrodes are stacked, and a deionization unit having electrode modules received therein to separate ions from water. The deionization electrode includes a current collector configured to have a circular flat structure, the current collector having a first hole formed therein, a first porous adsorption layer located on one surface of the current collector, the first adsorption layer being configured to have a flat structure, a second porous adsorption layer located on the other surface of the current collector, the second adsorption layer being configured to have a flat structure, a first ion selective membrane located on the surface of the first adsorption layer, and a second ion selective membrane located on the surface of the second adsorption layer.

Abstract: An image forming device and an operating method of an image forming device are provided. The operating method includes receiving first authentication information of a first user with respect to the image forming device, authenticating the first authentication information of the first user, based on reference account information of a plurality of users, the reference account information being stored in a storage based on a blockchain that distributes and manages a ledger in which user account information including authentication information and authority information of a user with respect to a certain image forming device has been recorded, when the authentication of the first user is completed, receiving a request to perform a first image forming job, and evaluating first authority information indicating an authority range of the first user, based on the reference account information of the plurality of users, and performing the first image forming job within the authority range of the first user.

Abstract: An image forming device and an operating method of an image forming device are provided. The operating method includes receiving first authentication information corresponding to an account of a first user, when the account of the first user is authenticated according to the first authentication information, preparing an operation of the image forming device according to usage authorization of the first user; receiving a request to provide job information of the first user, obtaining a first job list of the first user from a ledger on which job information of a user with respect to a certain image forming job is recorded, based on a blockchain in which the ledger is distributed and managed, and performing a first image forming job selected from the first job list.
