Abstract: The present disclosure relates a display device and a method compensating for deterioration thereof, and a mobile terminal including the display device. The display device includes: a display panel including a first pixel area, a second pixel area, and a third pixel area; a first optical device disposed below the display panel or embedded within the display panel in a predetermined sensing area on the display panel, the first optical device facing at least a portion of the first pixel area and a portion of the second pixel area when the display panel is folded or moved; and a pixel deterioration compensation circuit configured to operate to reduce a luminance difference between the first pixel area and the second pixel area by receiving sensing data from the first optical device in a deterioration sensing mode.

Abstract: A secondary battery includes an electrode assembly having a positive electrode provided with a positive electrode tab, a separator, and a negative electrode provided with a negative electrode tab, the positive electrode, the separator, and the negative electrode being wound, the electrode assembly having a core part at a center thereof; a can configured to receive the electrode assembly therein, the negative electrode tab being connected to the can; a cap assembly coupled to an opening of the can, the positive electrode tab being connected to the cap assembly; and a reinforcing member provided on an end of the separator exposed beyond the positive electrode or the negative electrode to prevent heat of the positive electrode tab or the negative electrode tab from being transferred to the separator.

Abstract: The composition based on a discharge from an oil refining plant after a desulfurization of heavy oils in the oil refining plant using a catalyst, comprising: 80% or less of vanadium; 80% or less of molybdenum; 20% or less of nickel; 30% or less of cobalt; 99% or less of alumina; and a trace of the impurities, which is catalytically active to purify the exhaust of diesel vehicles. A filter or a washcoat made of the discharged catalyst composition alone or in combination with ordinary filtering materials or ordinary washcoat materials can be very useful for purification of smoke. In addition, a catalyst in which at least one metal of the platinum group is uniformly impregnated on the filter is quite superior to conventional ones employing alumina or titania as a washcoat in stability to both high temperature and sulfur trioxide.
