Abstract: A display device includes a display panel in which a plurality of active areas including a first active area and a second active area is defined. The device includes a plurality of sub-pixels disposed in each of the plurality of active areas, and a gate driver disposed on the plurality of active areas. Each of the plurality of sub-pixels includes a first light-emitting diode (LED) that emits light in response to a driving current and a first lens that refracts the light emitted from the first LED and a second LED that emits light in response to the driving current and a second lens that refracts the light emitted from the second LED and has a different shape from the first lens. Accordingly, the device can operate in any one of a private mode and a share mode by using the first lens and the second lens.

Abstract: A light-emitting display device can include a display panel in which an active area including a first active area and a second active area, and a non-active area adjacent to the active area are defined. Also, the light-emitting display device can include a plurality of sub-pixels disposed in the active area, and a gate driver disposed on the non-active area. Each of the plurality of sub-pixels can include a first light-emitting diode (LED) that emits light in response to a driving current and a first lens that refracts the light emitted from the first LED. Also, the light-emitting display device can operate in different modes that have different viewing angles by using the lens to limit or control a viewing angle in each of the first and second active areas and the display panel can selectively change the viewing angle on demand.
