Abstract
An assembly (10; 20; 30) is formed of at least one support (11; 21; 31) with a deposit (13; 22; 33) of a getter material, to be used as back support of electroluminescent organic screens (known as OLEDs). The assembly provides provisional protection from atmospheric gases for the getter deposit until it is used in the screen. From the assembly is easily obtained a back support for OLEDs already having the getter deposit at the moment of use in the manufacture of these screens.

An assembly (10;
- 20;
- 30) comprising two rigid members (11,14;
- 21,21′;31,31′), the rigid members being essentially planar and impermeable to atmospheric gases, fixed to each other in a peripheral zone thereof and defining a sealed space, at least one of the members having thereon a deposit (13;
- 22;
- 33) of an alkali metal, alkaline earth metal or an oxide of these metals in a central portion (12) of a side of the member facing the sealed space, wherein the at least one member having the deposit comprises glass or metal, and wherein the sealed space is kept under vacuum or an atmosphere of a gas inert to the deposit.
