OLED displays

While liquid crystal displays (LCDs) always need a source of light behind the pixels, organic light-emitting diode (OLED) displays are far more advanced. With these displays the material itself irradiates the light, thus allowing for thinner displays and wider viewing angles. At the same time, these organic dyes produce a more intense color depth and therefore a more realistic picture. This advantage can clearly be seen in dark images: OLEDs are also able to show deep black on the screen.
Currently OLED technology is used to build mainly small displays, such as mobile phones or tablet PCs. In these often-used devices, another advantage of OLEDs becomes a reality: Because of their efficient power usage, these mobile devices have extended battery life.
However, OLED displays have higher requirements for the used semiconductor than other display types. Charge carrier mobility needs to be much higher for OLEDs than for LCDs; and to get a uniform picture, the semiconductor must be extremely stable under current stress.
Our coatable semiconductor iXsenic meets all the rigorous requirements for OLED displays. Besides high charge carrier mobility, our product has superior stability under constant current stress.
