Patent number: 10485147Abstract: A display device is provided to achieve air circulation through an inner structure or an outer structure of the display device for efficient heat dissipation. The display device includes a housing, a display module mounted in the housing, a closed-loop air circulation system, and an open-loop air circulation system. The closed-loop air circulation system includes a first channel defined between a front surface of the display module and a front surface of the housing so as to extend along the front surface of the display module, and a second channel defined between one side surface of the display module and one side surface of the housing that is opposite the one side surface of the display module. The first channel is configured to receive air from a first end of the second channel and to discharge the air to a second end of the second channel.Type: GrantFiled: February 27, 2018Date of Patent: November 19, 2019Assignee: LG ELECTRONICS INC.Inventors: Honglyeol Oh, Sangjoon Oh, Byoungwook Han, Joongnyon Kim
