NanoPhotonica develops new QLED display technology
Mar 4th
Last month we reported about Samsung’s new 4″ active-matrix QLED display prototype , and now we hear that NanoPhotonica has developed new QLED technology (which they call S-QLED). Compared to current available OLED displays, S-QLED use fewer layers, is solution-processable (and can be produced using inkjet printing) and uses inorganic materials. In fact NanoPhotonica claims that S-QLED displays will be 75% cheaper than current OLEDs, be more efficient (by 30%) and will have double the lifetime. NanoPhotonica is currently working with several display manufacturers to commercialize the displays. The company hopes to bring this to market “soon”. read more

Super AMOLED Plus vs Super AMOLED video
Feb 14th
We’ve got a lot of Super AMOLED Plus news today. Here’s a short video comparing the Galaxy S2 (with its 4.3″ Super AMOLED Plus display) to a Galaxy S (4″ Super AMOLED ) and an iPhone 4 (3.5″ IPS-LCD). The most apparent thing about the S2 – it’s a big phone…

DisplaySearch sees rapid expansion of LTPS capacity for AMOLED and LCDs
Feb 9th
DisplaySearch says that strong demand for Low Temperature Polysilicon (LTPS) based displays (LCDs and AMOLEDs ) will drive rapid expansion of LTPS capacity. Spending on LTPS-equipment is expected to reach $2.4 billion in 2011 (and will decrease in 2012 and 2013). DisplaySearch says that making AMOLEDs and high-end LCDs like the ones used in Apple’s iPhone 4 is only currently possible with LTPS. In 2011, supply of both AMOLEDs and LTPS LCDs are forecast to be extremely tight. Leading panel makers are for the first time ever scaling LTPS technology to Gen-5.5 and larger substrates. read more

Researchers create a flexible array of inorganic LEDs
Oct 19th
Researchers led by John Rogers from the University of Illinois have developed a stretchable/bendable sheets of LEDs and light sensors. They are interested in applications that interface with the human body, and so they prefer inorganic LEDs to OLEDs as they are brighter, more reliable and are more easily made waterproof. The team has printed an interlaced array of LEDs, on a rigid wafer, then dissolved the top layer of the substrate to release a thin network of LEDs that can be transferred to a flexible, waterproof polymer sheet. Each LED is just 100 microns across (about the width of a human hair) and 2.5 microns thick and is connected to its neighbors by serpentine strands that can accommodate the deformation of stretching and twisting. They managed to put the arrays on aluminum foils, leaves ,sheets of paper and around nylon threads. read more

Amazon announces a new Kindle, with an improved E Ink display
Jul 29th
Amazon has just announced the third generation of their popular Kindle e-reader devices. The new Amazon Kindle is smaller, and lighter but still has the same display size. They are using E Ink ‘s next-generation “Pearl” displays which offer 50% improved contrast. There are two versions: Wi-Fi only and WiFi/3G . Both versions will ship on August 27th, and can be pre-ordered now . The Wi-Fi only will cost $139 , and will come in Graphite. The 3G version will cost $189 , and you can choose between white and Graphite. read more

CNet challenge: Are AMOLED displays better than LCDs?
Jun 22nd
CNet has posted an interesting video in which they test whether AMOLED displays are better than LCDs. The conclusions? The AMOLED provide better colors, but also less accurate ones. They also suffer under sunlight (although the new Super-AMOLEDs are quite good). See for yourself:

Sunlight visibility: Super-AMOLED vs AMOLED vs LCD
Jun 21st
TechBlog has done an interesting test, putting a Super-AMOLED vs a ‘regular’ AMOLED and an LCD in direct sunlight. They used 3 phones for the comparison: Samsung Galaxy S (4″ 480×800 super-AMOLED ), HTC Desire (3.7″ 480×800 AMOLED) and a Sony Ericsson Xperia X10 (4″ 480×854 TFT LCD). It seems that the best display is still the LCD, but the Super-AMOLED (which is a lot better than the regular AMOLED) comes close – and most of the times the difference is negligible. read more

Canon officially abandons SED TV technology
May 25th
Canon has officially abandoned the SED TV technology – they just couldn’t bring the cost down to make this a viable alternative to LCD TVs. Canon still plans to use SED panels for industrial and medical displays (high margin businesses). Via Ubergizmo

Graphene is used to create an alternative to OLED Lighting
Feb 6th
Researchers from Sweden and the US have produced a new transparent lighting component that is made from Graphene . They say it is cheap to make and fully recyclable, and might be an alternative to OLED Lighting . The new device is called an Organic Light-emitting Electrochemical Cell, or LEC. The Graphene is used for an electrode. LECs can be made using a roll-to-roll process, because all of its parts can be made from liquid solutions. There’s very little info on that new device (such as what is the actual light-emitting material, what’s the efficiency of it, etc.). Via Graphene-Info
