Applications: 1. The subject matter of the present invention is directed towards hybrid large area display involves integration of OLED technology and flexible pre-patterned substrates to create large area displays. 2. The hybrid display device comprising at least one organic 10 light emitting diode (OLED) segment and a pre-patterned flexible substrate. The OLED segment is integrated onto said pre-patterned flexible substrate using an interconnection technology for contacting at least a metal electrode on said OLED segment. 3. Such a hybrid display device will take advantage of uniform emission and large area scalability of OLED segments to allow modularity in design.
Advantages: 1. In the present invention as an example seven-segment display is made using individual few cm size OLED segments which can be scaled to larger sizes. Individual segments are integrated on a textile substrate. 2. Large displays made using this technology are modular and foldable, they give a very thin form factor and uniform light emission compared to current LED based technology. 3. The large area hybrid display having better aesthetics and thin form because of OLED segments, in addition to scalability to large area. 4. For OLED displays, the number of self-luminous diodes will be always 20 be much less compared to LEDs required for different segment sizes. This reduces the complexity of PCB design and drivers. 5. Modularity will allow assembly of large displays at the point of use. 6. Overall power consumption of the proposed OLED displays will be lower than similar sized LED display. 7. There will be no heat dissipation issues with increasing size of the display. 8. There is no need of any diffuser as OLEDs are area emitters which will make the display less bulky and lightweight compared with LEDs which are point sources. 9. Emission from OLED segments is also uniform compared to multiple LEDs.

I-Mitra(आई-मित्र) Welcomes You..
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
