A portable terminal including a touch screen and method for displaying a cursor thereof are provided. The method includes determining whether a capacitance is equal to or greater than a first critical value and is less than a second critical value, if the change of the capacitance is sensed in the touch screen, displaying a cursor in an area where the change of the capacitance is sensed, if the capacitance is equal to or greater than the first critical value and is less than the second critical value, and performing a function corresponding to the area where the cursor is displayed, if the capacitance sensed in the area where the cursor is displayed is equal to or greater than the second critical value.

摘要:
An organic light emitting display includes a first substrate including a pixel region in which organic light emitting diodes are formed and a non-pixel region formed on the outer circumference of the pixel region. A second substrate is attached to the first substrate, and a sealing is provided between the first substrate and the second substrate. The sealing includes a first frit layer and a second frit layer which melts substantially more easily than the first frit layer upon irradiation of a laser or infrared beam thereto.
