Abstract: A display device in an example includes a substrate having a plurality of subpixels, a thin film transistor in each of the plurality of subpixels, at least one planarizing layer on the thin film transistor, a plurality of signal lines on the at least one planarizing layer, a first insulating layer between the plurality of signal lines, and a light emitting diode in each of the plurality of subpixels. A thickness of the first insulating layer is smaller than a thickness of the plurality of signal lines such that a top surface of the plurality of signal lines protrudes from a top surface of the first insulating layer.

Abstract: A method for storing short message service in a mobile communication terminal, in which a new received SMS is stored at a user identity module (UIM) by performing a space exchange between a SMS storage space of the terminal and a SMS storage space of the UIM in a CDMA terminal having the UIM. The method includes: if the SMS is received, checking whether an empty region exists in a SMS storage space of the UIM or not; if an empty region does not exist, performing a space exchange between the SMS storage spaces of the terminal and the UIM; and storing a new SMS in the empty SMS storage space of the UIM generated by the space exchange.

Abstract: A method for loading an operation program onto a mobile terminal, which includes comparing a first security code of the operation program provided by a communications company for operating the mobile terminal with a second security code of a downloading program used for downloading the operation program onto the mobile terminal, and determining whether or not a loading operation for loading the operation program onto the mobile terminal is legal based on the comparison of the first and second security codes.
