Abstract: A display device includes a display portion including a first surface, from which light is emitted in a first direction, and a second surface opposite to the first surface, a first optical portion disposed on the first surface, and a second optical portion disposed on the first surface to be spaced apart from the first optical portion in a second direction crossing the first direction. Each of the first and second optical portions includes a multi-channel lens through which the light from the first surface passes, a first infrared light source, a first camera, and a first lens frame coupled to the multi-channel lens in the first direction to support at least a portion of the multi-channel lens. The first lens frame may include a first recess structure in which the first infrared light source is disposed and a second recess structure in which the first camera is disposed.

Abstract: A photovoltaic system and a control method therefor are disclosed. A photovoltaic system according to an embodiment of the present disclosure comprises: a solar cell array for converting solar energy into electric power; a power management device for monitoring the power generation amount of the solar cell array and the reverse power from an external power grid; an energy storage device charged by receiving the electric power produced by the solar cell array or the power of the external power grid; and a power control device for supplying, to the energy storage device, the electric power generated by the solar cell array or the power of the external power grid in response to a valid power command, wherein the power management device generates the valid power command which has different values according to whether the reverse power is generated by the external power grid.
