Active Matrix of Any Shape with Organic Light Emitting Diodes displays (AMAzOLED)
Date du début: 1 janv. 2008, Date de fin: 31 déc. 2010 PROJET  TERMINÉ 

The target of project is to develop a highly reliable high brightness conformable low cost up scalable display for demanding applications such as their use in cars, aircraft or extreme sports applications. For the time being, in these applications, the LCD is the main display technology. Although its performances are appropriate in such difficult environments, designers are looking for a solution easier to integrate. For example, the LCD backlight makes it very bulky in aircraft, both because it has to supply a lot of light and therefore needs a cooling system but also because of an heavy bezel to handle a high level of vibrations. The backlight is even more critical in systems where the display is bent or is non-rectangular like in innovative design for car but also where the weight is a major issue such as in sports items. The solution to these issues is an emissive display technology for which both lighting and information content are integrated at the pixel level. Organic Light Emitting Diodes (OLED) made tremendous progress in the last 2 years. AMAzOLED is planning to push the technology to its limits to achieve the expected display function for car, aircraft and extreme sports goods. The display will use colour filters on white OLED to achieve the brightness and the reliability for the light emission. The OLED does not have to be referenced to the pixel element. Each pixel element will be driven by a polymorphous TFT with a higher reliability compared to a-Si TFT without degradation on other parameters. Both new OLED and new TFT technologies are compatible with existing industrial means thus limiting the capital expenditure to manufacture the product at a lower cost. The concept is designed to enable 2mm thick big size high-resolution TV products in a near future. The display will be built on peelable polyimide on glass as developed in FLEXIDIS. Using conformal displays offers a higher capability of integration in the envisaged applications.
