Abstract: Embodiments of the present disclosure can significantly reduce the non-display area of a flexible OLED display, which would otherwise be covered by a cosmetic trim such as a bezel or an opaque. As such, an electronic device with a display having minimized border area can be provided. This makes it possible to reduce the overall size of the electronic device without sacrificing the size of the display therein. Such a reduction in size of the bezel was achieved by bending the flexible substrate near its edge using an insert member.

Abstract: Disclosed herein is a cooling system for vehicle battery packs, including a double filter device mounted at an air inlet part, through which air for cooling the battery pack is introduced from the outside and/or the inside of the vehicle. The double filter includes a pre-filter having relatively large air holes, the pre-filter having high frequency of replacement, and a medium filter having relatively small air holes, the medium filter having low frequency of replacement. The pre-filter is located before the medium filter in the direction in which the air is introduced. Consequently, dust is removed from air, and therefore, the cooling efficiency of the battery pack is increased. In a preferred structure, metal dust is also effectively removed by the magnetic force applied to the medium filter. Consequently, the malfunction or short circuits of the battery pack are prevented.

Abstract: Disclosed herein is a battery module including a plurality of unit cells stacked one on another. The battery module has a cooling system that accomplishes contact type cooling by a coolant flowing through gaps (flow channels) defined between the unit cells, and the flow channels defined between the unit cells are at a predetermined angle to the flowing direction of the coolant at inlet ports of the flow channels.

Consequently, the occurrence of the velocity gradient of the coolant in the flow channel defined between the unit cells is prevented, and therefore, the cooling efficiency of the battery module is improved.
