• White top-emitting OLEDs with a down-conversion (DC) layer are demonstrated.
• The WTEOLED shows excellently angle-stable characteristic.
• The CIE coordinates at 20 mA/cm2 only shift by (0.023, −0.007) from 0° to 60°.
• The TEWOLED shows a maximum current efficiency of 3.95 cd/A.
Angle-stable white top-emitting organic light-emitting devices (WTEOLEDs) by the combination of a blue TEOLED with a down-conversion (DC) layer are demonstrated. The DC layer is composed of red fluorescent dye doped in a host of tris (8-hydroxy-quinolinato) aluminum. The TEWOLED shows a CIE coordinates of (0.240, 0.332) and a maximum current efficiency of 3.95 cd/A. Furthermore, the WTEOLED shows excellently angle-stable characteristic, the CIE coordinates at 20 mA/cm2 only shift by (0.023, −0.007) from 0° to 60°. It can be attributed to the angle-stable blue TEOLED based on the Ag/Ge/Ag transparent cathode.
