Abstract: A display device includes a substrate, a first electrode and a second electrode which are spaced apart from each other in a second direction, light-emitting elements spaced apart from each other in the first direction, a first contact electrode electrically contacting the light-emitting elements, and a second contact electrode electrically contacting the light-emitting elements. The first contact electrode electrically contacts the first electrode through a first contact portion disposed on the first electrode, the second contact electrode electrically contacts the second electrode through a second contact portion disposed on the second electrode, the first contact portion is disposed on an end portion in the first direction of the first contact electrode, and the second contact portion is disposed on an end portion in the first direction of the second contact electrode.

Abstract: A Firmware Over-The-Air (FOTA) based data update method and a mobile terminal of supporting the same are provided. The FOTA based data update method for a mobile terminal includes loading a pre-boot file stored in a second memory in a pre-boot loading area of a first memory, identifying version information of a first version bootloader file stored in a first bootloader file area and a second version bootloader file stored in a second bootloader file area, loading a newer version bootloader file, corresponding to a new one of the first version bootloader file and the second version bootloader file, in a bootloader loading area of the first memory, loading, upon bootloader file activation, a FOTA engine and activating the FOTA engine, and updating, upon FOTA engine activation, a bootloader file area storing the older version bootloader file on the basis of received boot related data.
