Abstract: A display apparatus is provided. The display apparatus includes a display panel, a chassis configured to support the display panel, a backlight unit configured to be installed on the chassis, and an electricity generator configured to use the backlight unit as a heat source to generate electricity. The electricity generator includes a heat transfer unit which contacts the backlight unit, at least one heat storage unit which contacts the heat transfer unit, and at least one thermoelectric device comprising a heat generator and a heat absorber contacting the heat transfer unit. The at least one thermoelectric device absorbs heat, which is generated from the backlight unit, through the heat transfer unit in response to the backlight unit being driven and absorbs heat from the at least one heat storage unit through the heat transfer unit in response to the backlight unit not being driven.

Abstract: An energy harvesting apparatus includes a housing that includes an internal portion filled with dielectric liquid in a vacuum state, first and second electrode portions that are disposed to face each other in the housing and configured to be polarized with different polarities, a first layer that forms a path along the internal portion of the housing to allow the dielectric liquid and bubbles generated from the dielectric liquid to flow through the path, and a second layer configured to insulate the first and second electrode portions from the housing. The bubbles are generated from the dielectric liquid when thermal energy is applied to the housing. The first and second electrode portions may change a dielectric constant of the dielectric liquid when the bubbles move between the first and second electrode portions to generate current.
