Abstract
A display apparatus includes a substrate, a plurality of pixelated first electrodes disposed on the substrate, an uneven surface structure or a porous structure disposed between adjacent pixelated first electrodes, a plurality of OLED lighting elements disposed on the pixelated first electrodes and the uneven surface structure or the porous structure, a second electrode layer disposed on the OLED lighting elements. Equivalent transport distance of carriers along the uneven or porous surface increases accordingly, thereby resulting in reduced lateral leakage current between adjacent pixelated first electrodes.
