Abstract: A light emitting display panel is disclosed that comprises a display area including light emitting areas, each of the light emitting areas including subpixels in the light emitting area. Viewing angle switching units are in a non-display area and each viewing angle switching unit is connected to the subpixels included in a corresponding light emitting area. Each subpixel includes a first light emitting unit driven by a first viewing angle control transistor that is controlled by the viewing angle switching unit that is connected to the subpixel where the first light unit includes a first lens having a first shape, and a second light emitting unit driven by a second viewing angle control transistor that is controlled by the viewing angle switching unit that is connected to the subpixel where the second light emitting unit includes a second lens having a second shape.

Abstract: A display device may include a first narrow angle control line for being electrically connected to a first viewing angle control circuit, a first wide angle control line for being electrically connected to the first viewing angle control circuit, and a first subpixel for being electrically connected to the first viewing angle control circuit, thereby controlling the viewing angle of a specific area of the display panel.

Abstract: An OLED display includes a plurality of pixel lines each connected to a plurality of pixels, the plurality of pixel lines including at least two adjacent pixel lines, each pixel including a driving TFT, a first switching TFT, a second switching TFT, and an emission control TFT connected to the driving TFT. The OLED display also includes a first scan driver controlling the first switching TFTs for the two pixel lines. The OLED display also includes a second scan driver controlling the second switching TFTs for the two pixel lines. The OLED display also includes a third scan driver configured so that all of the emission control TFTs for the two pixel lines are turned on in a programming period, maintain a turn-on state for a portion of an emission period, and can adjust an on-time duty of the emission period after the portion of time.
