    Abstract: An inkjet printing device includes a stage part including a stage, an inkjet head part including at least one inkjet head that disposes an ink on the stage, the ink including dipoles and a solvent having the dipoles, a heat treatment device that removes the solvent, a first sensing part that measures a position of the ink disposed on the stage, a second sensing part that measures a position of the inkjet head, and a third sensing part that measures a position of each of the dipoles disposed on the stage. A dipole aligning method includes disposing an ink on a substrate, the ink including dipoles and a solvent having the dipoles, generating an electric field on the substrate and disposing the dipoles on the substrate by the electric field, removing the solvent, and measuring a position of each of the dipoles disposed on the substrate.

    Abstract: A display device includes a display panel including a display area having first and second areas for displaying an image. The display panel is positioned in first and second states. A sensing panel is disposed on the display panel and includes sensing electrodes. A panel driver drives the display panel. A sensor driver drives the sensing panel. The panel driver drives the first and second areas at a first driving frequency when the display panel is in a first state and drives the first area at the first driving frequency and drives the second area at a second driving frequency lower than the first driving frequency when the display panel is in the second state. The sensor driver drives the first and second areas in a sequence that includes the first and second sensing modes each for a predetermined time, when the display panel is in the first state.

    Abstract: A display device includes a first substrate having a light-emitting element. A second substrate is disposed over the first substrate. A sealing member is disposed between the first substrate and the second substrate. The sealing member couples the first substrate and the second substrate together. The sealing member includes a first linear portion extending in a first direction, and a second linear portion extending in a second direction different from the first direction. A maximum width of the first linear portion is greater than a maximum width of the second linear portion.

    Abstract: A display device includes a first substrate and a second substrate. The first substrate includes a first base substrate, a drive layer, and an optical layer, and is divided into a display area, and a non-display area. A first connection pad and a second connection pad are disposed in the non-display area. The second substrate is disposed facing the first substrate, and includes: a second base substrate including a sensing area, and a non-sensing area; and a touch sensor disposed on the second base substrate. The touch sensor includes a touch sensing electrode, a touch pad, and a sensing line electrically coupling the touch sensing electrode with the touch pad. The non-display area of the first substrate is bent so that the first connection pad is electrically coupled with the second connection pad, and the second connection pad is electrically coupled with the touch pad.
