US 2021/0083040 A1 · OLED TILED DISPLAY AND A RELATED TILING METHOD

Abstract

The OLED tiled display includes front and back lighting display units that emitting lights toward each other. The front lighting display unit includes a first substrate and a first organic light emitting device. The back lighting display unit includes a second substrate and a second organic light emitting device. The first and second light emitting devices neighbor laterally on each other, but are vertically aligned to a second extended section of the second substrate and a first extended section of the first substrate, respectively. The present invention achieves small gaps and resolves the problem of obvious gaps in an OLED tiled display by piecing together the front and back lighting display units, where the substrate of the front lighting display unit functions as encapsulation layer to the back lighting display unit, and the substrate of the back lighting display unit functions as encapsulation layer to the front lighting display unit.
