    Abstract: A display device includes a curvature-variable display panel including a plurality of pixels; a controller configured to correct and output an image signal supplied from the outside according to a radius of curvature of the display panel; a data driver configured to supply a data signal corresponding to the corrected image signal to a data line connected to the pixel; and a scan driver configured to supply a scan signal synchronized with the data signal to a scan line connected to the pixel. The controller may include a curvature detector configured to detect the radius of curvature of the display panel and a lookup table generator configured to generate a correction lookup table according to the radius of curvature of the display panel.

    Abstract: A display device includes a display unit having pixels, a touch sensing unit including touch electrodes disposed on the display unit, and a touch driver configured to supply a touch driving signal to the plurality of touch electrodes and receive a touch sensing signal from the touch electrodes. The touch driver supplies a first touch driving signal having a first phase to one or more first touch electrodes, and supplies a second touch driving signal having a second phase opposite to the first phase to one or more second touch electrodes, at least a part of which is disposed across a specific point from the first touch electrodes. The touch driver receives a first touch sensing signal having the first phase from at least one of the first touch electrodes, and receives a second touch sensing signal having the second phase from at least one of the second touch electrodes.

    Abstract: An optical member and a display device including the same. The optical member includes a light guide plate including a surface disposed on a plane defined by a first direction and a second direction crossing the first direction, a low refractive index pattern disposed on the surface of the light guide plate and including an opening for exposing the surface of the light guide plate, a wavelength conversion layer disposed on the low refractive index pattern, and a passivation layer disposed on the wavelength conversion layer and covering a side surface of the wavelength conversion layer and a side surface of the low refractive index pattern at least one side portion. The low refractive index pattern has a lower index of refraction than the light guide plate, and a ratio of an area occupied by the low refractive index pattern to an area of the surface of the light guide plate decreases in the first direction.

    Abstract: A backlight unit and a display device are disclosed. The backlight unit includes a substrate, light sources, a side mold, a resin layer, and an optical member. The light sources are disposed on a surface of the substrate. The side mold is fixed to the substrate and surrounds the light sources. The resin layer fills a region defined by the side mold. The optical member is disposed on the resin layer. A first height of the side mold measured from the surface of the substrate is greater than a second height of the resin layer measured from the surface of the substrate. The display device includes the backlight unit and a display panel disposed on the backlight unit. Manufacture of the unit includes forming the substrate with the light units disposed on the surface, attaching the side mold to the substrate, and forming the resin layer and the optical member.
