Abstract:
An organic light emitting display device includes a substrate, a first pixel configured emit light having a first color, and a second pixel configured to emit light having a second color different from the first color. Each of the first and second pixels comprises a first electrode formed over the substrate, a light emission layer formed over the first electrode, an electron transport layer formed over the light emission layer, and a second electrode formed over the electron transport layer. The electron transport layer comprises a first electron transport material and a second electron transport material different from the first electron transport material. A ratio by weight of the first electron transport material to the second electron transport material in the first pixel is substantially different from that of the first electron transport material to the second electron transport material in the second pixel.

Abstract:
An organic light emitting diode (OLED) display includes a substrate where OLEDs are formed and an encapsulation member fixed onto the substrate while covering the OLEDs. The encapsulation member includes a photochromic material so that the encapsulation member is colored by external light.
Abstract:
An organic light emitting display apparatus effectively improves viewing angle characteristics. The organic light emitting display apparatus includes a plurality of sub-pixels configured to emit light of different colors, respectively; a thin film encapsulation layer for sealing the plurality of sub-pixels; and a light scattering layer disposed over the thin film encapsulation layer to scatter light output from the plurality of sub-pixels.

Abstract:
A display panel test apparatus that may include: a first measurer measuring first R, G, and B components of light emitted from a display panel at a first viewing angle; a second measurer measuring second R, G, and B components of light emitted from the display panel at a second viewing angle; a color coordinate calculator calculating a first xy color coordinate at the first viewing angle using the first R, G, and B components and calculating a second xy color coordinate at the second viewing angle using the second R, G, and B components; and a panel controller compensating a target color coordinate of the display panel to include the first xy color coordinate and the second xy color coordinate into a specification area on a color coordinate system.
