Researchers from Sweden's Chalmers University have developed a new "double doping" process that basically doubles the efficiency of Polymer OLED emitter materials.

The researchers explain that doping in organic semiconductors operates through what is known as a redox reaction, in which the dopant molecule receives an electron from the semiconductor which increases the electrical conductivity of the semiconductor. The efficiency limit of current doped organic semiconductors has been limited by the fact that each dopant molecule was able to to exchange one electron only. In the new research it was shown how it is possible to move two electrons for every dopant molecule which increases the conductivity of the organic material.

HDTVTest posted an interesting interview with Cadmium-Free QD developer Nanosys CEO and president Jason Hartlove. In this long interview Jason discusses the company's technology and recent achievements.

Jason reveals that the company is working on emissive Quantum Dots displays - and he expects to have a full-color monitor-size QLED display prototype ready by the end of 2019. Jason says that they hope to show these display prototypes in private demos at CES 2020.

China-based Hisense announced a new technology that the company says will enable its LCDs to compete with OLEDs in high contrast. The so-called ULED XD panels use two LCDs panels, one on top of the other. The inner LCD is a monochrome (greyscale) FHD LCD that is used to block the light on low brightness images, and on top of it is the usual 4K full-color LCD.

This is basically a way to achieve a high number of 'local dimming' zones for an LCD display (over 2 million such zones, in fact). The TV itself is very bright (over 2,900 nits) and reportedly offers a great image quality and an almost perfect contrast. HiSense it will release its first ULED XD TVs later this year in China. Apparently SkyWorth is also demonstrating a similar technology at CES.

LG Display is showing 55" transparent OLED TVs at CES 2019, and here's a video that shows the display in action:

LGD says that its 55" OLEDs feature a transparency of 40%. The company has been showing its large-area transparent OLEDs for many years, but we're still waiting for this technology to be commercialized.

LG announced some exciting products at CES 2019, including the world's first rollable TV and the world's first 88" 8K OLED TV. LG also impressed CES attendees with its huge "LG OLED Falls" display.

The "LG OLED Falls" is comprised of 260 55-inch LG OLED TV displays - 76 concave ones, 72 convex ones and 112 flat ones. The whole display is 6 x19.8 meters in size.

Dell announced that its premium 15" laptops will all get an optional OLED display in 2019. The Dell XPS 15, Dell G7 15 and the Alienware m15 will all offer a 15" OLED display that features HDR, a 100% DCI-P3 color gamut and 100,000:1 Contrast Ratio.

The new 15" Dell OLED laptops will start shipping in March 2019. That's great news from Dell, and it's a great start for 2019 as it seems to be poised for an OLED laptop comeback.

Razer unveiled two new laptop concepts at CES, based on the company's 15" Razer Blade laptop. One of the concepts spots a 4K touch OLED display (the second used a 240Hz FHD LCD).

Razer says that the OLED display delivers "amazing color, deep blacks, and efficient performance". The company did not disclose if and when it aims to release this as an actual product.

Austria-based Sensor developer AMS announced a new RGB light and proximity sensor IC that can be placed behind an OLED screen, and still accurately measure the intensity of ambient light. This will enable OLED smartphone makers to further reduce the front bezel and place yet another component behind the OLED display.

The TCS3701 senses the light that passes through the display, and using unique algorithms the sensor can detect ambient light levels accurately without any information regarding the display pixel brightness above the sensor. The whole system package is 2 x 2.5 x 0.5 mm in size and so fits behind the smartphone OLED display.

Israeli-based InZiv announced that it has successfully closed a Series A round, raising $2.5 million from Maverick Ventures Israel.

Using proprietary technology, InZiv designs and manufactures inspection equipment based on highly specialized nano-scale optics and near-field microscopy. InZiv's equipment is specifically designed to test next-generation display - such as OLEDs, Micro-LEDs and QLEDs. InZiv says that its nano-optical and metrological inspection equipment offers the ability to study a wide variety of defects not detectable with existing tools.
