Reports say that the OQO model 02+ OLED display is not as efficient as expected


There are reports that the new OQO Model 02+ UMPC OLED display is not as efficient as you'd expect. The PC is not available yet, but there are some pre-production models around, and someone tried to see how much power the display takes.

As far as I understand, they tested the  power-consumption of the entire PC - and it's not so good - but it may be the fault of other components and not just the display.

Fraunhofer Shows OLED-on-CMOS-Integration for Sensor Applications


Fraunhofer IPMS Logo
During the Photonics West 2009 the Fraunhofer IPMS will present the prototype of a bi-directional OLED microdisplay with an imaging CMOS photo diode matrix interlaced in a QVGA display (12 x 9 mm²), both are integrated and work at the CMOS chip.



Furthermore, an optical flux sensor will be presented, which includes the required light source on the CMOS-sensor chip. A CMOS photo diode line allows the detection of the speed of a particle flow and an embedded OLED light source in the form of stripes in parallel to the photo diode line provides the illumination of the medium.



Due to the achieved reduction of the expenditure regarding the construction and circuit technology numerous applications of those devices are enabled. Fields of application vary from chemistry, medicine to life science. Other applications of OLED-on-CMOS include light barriers, opto-couplers and optical communications.

LG Display posts quarterly loss, will move investment to AMOLEDs or Solar Cells


LG Display has posted a quarterly loss of around 500M$, the first loss in two years - due to falling prices and slow demand for TVs. It did however post a record in sales and operating profits for the entire of 2008.



The company will invest 425M$ to increase capacity of small-sized displays (including OLEDs probably). 



LG also said they will invest more in AMOLEDs or Solar Cells.
