Electro-optical device with cover having a first wall indentation for accommodating control electronics
First Claim
1. An electro-optical device comprising:
- a light-transmitting substrate (1);
a stack (2) of layers on the substrate (1), which stack comprises a first, light-transmitting electrode layer (3) near the substrate (1), a second electrode layer (4) and an organic electroluminescent layer (5) between the first (3) and the second electrode layer (4);
a hollow cover (10) placed over the stack (2), which cover is connected to the substrate (1) in a gastight manner and has a first wall (11) extending along the stack (2); and
a water-binding getter (12) accommodated in the cover (10) so as to abut against the first wall (11), characterized in that the first wall (11) of the cover (10) is provided with an indentation (13), wherein control electronics (14) is accommodated so as to be electrically connected to the first electrode (3) and the second electrode (4).

Abstract
An electro-optical device comprises a stack (2) of layers on a substrate (1), which stack of layers includes an organic luminescent layer (5) sandwiched between electrode layers (3, 4). A hollow cover (10) is provided over the stack (2) and connected to the substrate (1) in a gastight manner. A water getter (12) is accommodated in the cover (10) so as to abut against a wall (11), which extends along the stack (2). The wall (11) has an indentation (13) accommodating control electronics (14) used to operate the device. The control electronics (14) may be connected to the device by way of a flexible toil (15) having conductor tracks (16), and fixed in the indentation (13) by way of an adhesive (17).
