Germany - The Novaled ( http:// ) 15x15 cm OLED device reaches a power efficiency of 30 lm/W at an initial brightness of 1,000 cd/m2. It shows a high quality white light with CIE color coordinates at illluminant A Being in line with DoE energy star specifications. By using Novaleds proprietary liternity technology a lifetime of 20,000 h can be reached.
Novaled developed a 15x15 cm white OLED with a thickness of less than 2 mm. The Novaled OLED stack allows for a natural and warm white light performing a very high color rendering index (CRI) of 90. The perception of this light is similar to sunlight The what is the color of the sth.
With this large area flat light element OLEDs will enable a pleasant illumination of the room together with revolutionary design. By reaching 30 lm/W on a 15x15 cm area Novaled achieved an intermediate step in line with the European project OLED100.
The specific electrode structure Novaled developed and now commercializes under the name liternity increases the device lifetime. Using the liternity technology the 15x15 OLED device can reach a lifetime of 20,000 h. Liternity OLEDs maintain the appearance of a homogeneously lighted-up surface over the entire life Span of the OLED.
The liternity technology will allow the upscaling towards very large OLED panel sizes. Long lifetimes will be crucial to reduce maintenance cycles for commercial applications.
Novaled is using his leadership on power efficiency and long lifetime to pave the way for large and thin lighting products which the market is expecting from OLED, says Gildas Sorin, CEO of Novaled.
The performance of this 15x15 OLED element perfectly illustrates the potential of both: Novaled PIN OLED (3) and liternity technology. It reflects as well our company is dealing with the market requests and various aspects of a lighting product going beyond the OLED stack and materials.
