Abstract

An OLED panel includes a light emitting substrate and a color filter substrate. The light-emitting substrate includes a multi-layer OLED film emitting white light. The color filter substrate includes a color filter array, a conductive layer that is electrically connected to a wall-shaped elastic conductor that is wearing a metal cap. The two substrates are laminated together in a manner that the metal cap is in direct contact with cathode electrode of the OLED at the site of pixel definition layer. The total resistance of the cathode layer of the OLED is therefore reduced significantly, and voltage-drop on cathode and associated image artifacts are minimized.
