    Abstract: A dust sensor includes a multi-wavelength light source, a receiver, and a controller. The light source emits light of different wavelengths. The receiver generates one or more acoustic wave measurement values based on acoustic waves irradiated from the light source to air particles. The controller controls at least one flickering cycle of the light source, determines the type particles based on the acoustic wave measurement values, and calculates the concentration of particles. The controller calculates the concentration of particles in proportion to an intensity of the acoustic wave measurement values, and determine the type of particles based on the acoustic wave measurement values. The acoustic waves are generated differently based on wavelengths of light emitted from the multi-wavelength light source.

    Abstract: There is provided a display device including a display panel including first panel pads arranged along a plurality of rows, each of the rows extending in a first direction in a plan view, wires extending in a second direction crossing the first direction, each of the wires including a first bonding portion attached to a corresponding one of the first panel pads, and a first circuit board including first pads connected to the wires. The first panel pads in a first row of the plurality of rows in a plan view are exposed in the second direction crossing the first direction between the first panel pads in a second row neighboring to the first row of the plurality of rows.

    Abstract: A display device may include: a base layer including a plurality of islands, at least one first bridge configured to connect the islands in a first direction, and at least one second bridge configured to connect the islands in a second direction; and at least one pixel including a plurality of sub-pixels in the base layer. Each of the sub-pixels may include: a first electrode and a second electrode in one island of the islands and spaced from each other; a third electrode and a fourth electrode in one bridge of the at least one first bridge and the at least one second bridge and spaced from each other; at least one first light emitting element between the first electrode and the second electrode; and at least one second light emitting element between the third electrode and the fourth electrode.
