TV industry facing a big change: OLED & QLED could soon be history

Several scientists from Linköping University in Sweden are currently working on the development. They are cooperating with other researchers from China, Great Britain and the Czech Republic. However, there is still a major hurdle: the lifespan of the perovskite solar cells is just over 100 hours. This is of course far too little for the mass market. Even OLEDs run for several 10,000 hours and LCDs are even more durable.

Then why are you working on perovskite crystals for screens? Well, the crystals don’t need clean rooms or high temperatures to grow and could lower the cost of manufacturing displays. At the moment you also have to work with iodine and lead – you would like to do without the latter. The perovskite crystals are embedded in a matrix of organic molecules and are formed into a thin film by the scientists.

No equivalent substitute has yet been found for lead, otherwise the researchers would like to do without it, the researchers involved. The next step would be to test differently composed perovskite crystals and other organic molecules. Because before one could even think of the mass market, one would have to increase the durability, stability and color palette. One of the scientists’ goals is to develop a white light-emitting diode. Manufacturers of displays are likely to watch the development with interest.
