The latest display technology will be at electronica 2010, with LEDs, OLEDs and AMOLEDs being featured.

As flat and as thin as possible, with high energy-efficiency levels and the highest-resolution. Display manufacturers will be focusing on these features at electronica 2010, the world’s leading trade show for components, systems and applications.

LED, OLED and AMOLED technologies are gaining ground in the areas of e-signage, smart phone displays and television sets, and are promising to create a technical revolution. And Samsung will present its new LED large-format displays aimed directly at the e-signage market.

The new LED displays in Samsung’s EX(n) series, which will be presented at electronica this year, combine size and energy efficiency. Weighing just 15 kilograms and with a depth of 40 millimetres, they rank among the lightest in their class and also use 60% less energy compared with conventional displays. The new LED SyncMaster 400EX(n), 460EX(n) and 550EX(n) with screen sizes of 40 inches, 46 inches and 55 inches respectively are especially suitable for digital signage applications in airports, shopping centres or conference venues, and boast full HD resolution with a refresh rate of 120 Hz.

Kingbright Electronic Europe GmbH will also present the first dome lens SMD-LED in a 0603 package. This new helios SMD LED has a 60° angle of radiation and supplies a typical brightness of up to 3000 mcd@20mA in the colour red. The industrial component complies with temperature specifications between -40°C and +80°C and was developed especially for the automatic pick-and-place mounting process.

dilitronics GmbH will present its innovative controLED technology, which prevents temperature, age, and production-induced inhomogeneity of LEDs. Thanks to a freely programmable microcontroller, the parameters of every LED can be controlled precisely. The potential of LEDS is therefore exploited to the full.

Power Systems GmbH+Co.KG, Deutschland, will present its brand-new PS-LPL0801-01 backlight converter at electronica 2010. With an output power of 9 Watts it can control a large number of TFT displays containing LED backlight systems. Thanks to flexible interconnection of up to 8 outputs, LED flows from 15 to 240mA can be attained. The converter (measuring 64mm x 32mm x 9mm) can easily be integrated in customer applications. It is used in industry, medical electronics and lighting systems.

In the area of OLEDs, Data Modul AG will present passive-matrix OLEDs at this year’s electronica. One highlight will be the new 14 cm (5.5in) PMOLED UG-5664ASGGF01 (UN10033). This monochrome (green) product has a resolution of 256 x 64 pixels and is currently the largest PMOLED available with dimensions of 146mm x 65mm x 2mm. The application is used in medical monitoring monitors.

Under the motto ‘big sizes - low energy - 3D - touch’, the Display/e-Signage Forum on 9 November 2010 will feature innovations and future trends in the display industry. Unlike other forums at electronica, the Display/e-Signage Forum will contain a talk area – a ‘speaker’s corner’ with talks and podium discussions – and a presentation area where exhibitors can promote innovative products.

In the area of AMOLED displays for smart phones, the market research company iSuppli is forecasting an average growth rate of 55.1% up to 2015. Since an AMOLED display does not require any backlight, energy consumption is reduced and a normal display can be just a few millimetres thick. AMOLED displays can also be printed on nearly every material and are extremely elastic. Consideration is already being given to the integration of displays in items of clothing.

The quarterly OLED Shipment and Forecast Report by DisplaySearch shows that OLED displays will have a market volume of $5.5 billion with an average annual growth rate of 37% by 2015. Samsung is reacting in this respect and will invest a total of $2.2 billion in AMOLEDs and OLEDs up to 2012. However, market researchers do not regard smart phone displays as the most important source of income with OLEDs and AMOLEDs in the longer term. According to DisplaySearch, television sets will also account for a worldwide turnover of $1.92 billion in 2015.
