Researchers discover a new way to improve the current injection in OLED devices

Researchers from the Max Planck Institute for Polymer Research developed a way to improve the current injection from the positive electrode in OLED panels. To enhance the hole injection the researchers covered the positive electrode with an ultrathin layer of an organic semiconductor as a spacer layer between the electrode and the light-emitting organic semiconductor.

The researchers say that they did not actually expect that adding an extra layer and eliminating the physical contact between the electrode and the emitting layer actually improves the electrical contact.

UBI: The flexible OLED market will reach $17.6 billion in 2020

UBI Research estimates that the flexible OLED market will generate $1.8 billion in revenues in 2015, and will grow quickly at a 60% annual growth rate (CAGR) to reach $17.6 billion by 2020. The primary application driving this grwoth will be tablet pcs.

UBI also says that Samsung decided to change the encapsulation technology used in their upcoming A3 production line. In their current flexible OLED production, Samsung uses the old Vitex technology which is slow and expensive.

LG announced it will bring a new OLED TV to CES, the new panel weighs 3.5Kg

LG announced that it is bringing its OLED TVs to CES 2013 (January 8-11)- and the company further enhanced its 55" WRGB OLED TV in technology and in design. The new model weighs just 3.5Kg (500 grams less than the older one shown at CES 2012) and is still 4mm thick. As LG says in its PR: "LG Display is truly laying the prologue for the new OLED TV era".

LG's OLED TV features FPR passive 3D, 100,000,000:1 contrast ratio and fast response time (1,000 times faster than LCD according to LG). The TV is based on LG Display's Oxide-TFT white-OLED with color filters (WRGB) OLED panel. The TV is expected to launch in 2013 for a price of around $10,000 at first. Earlier this month the TV (model 55EM9700-UA) passed through the FCC as it includes Wi-Fi and Bluetooth modules and so needs to get approved by the FCC before it can be sold in the US.
