new LED large-format 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 save up to 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 are very impressive thanks to their 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 (dimensions: 64 x 32 x 9 mm) can easily be integrated in customer applications. It is used in industry, medical electronics and lighting systems.
Innovations in OLED technology
An OLED is an organic light-emitting diode which, compared with an anorganic light-emitting diode (LED), has lower current density and luminance. OLED displays also do not require any backlight because the diodes themselves emit light when a voltage is applied. This means that OLED displays are flatter and more energy-efficient and have a higher contrast than conventional displays.
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 (5.5) 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 146 x 65 x 2 mm. The application is used in medical monitoring monitors.
Display / e-Signage Forum during electronica
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 on Stand A3.221. Unlike other forums at electronica, the Display/e-Signage Forum will contain both a talk area – a “speaker’s corner” with talks and podium discussions – and a presentation area where exhibitors can promote innovative products.
High growth expected with LEDs, OLEDs and AMOLEDs
Especially 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 (source: iSuppli). 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 (source: DisplaySearch).
It is also anticipated that sales of LEDs will double by 2013 to €14.3 billion compared with $6.7 billion in 2009. Strong growth is expected in this segment, primarily on account of the wide range of applications of very bright LEDs (source: iSuppli).
