Researchers develop new OLED structure that enables directional and polarized emission

Scientists from North Carolina State University and the University of Texas have developed and demonstrated a new approach for designing photonic devices. The new method enabled the team to control the direction and polarization of light from thin-film LEDs, overcoming the widely known obstacles of beam shaping that arise from their Lambertian nature. Such LEDs with directional and polarized light emission could be useful for many photonic applications.

TCL brings perovskite-QDs enhanced LCDs to market, in a pilot project

TCL collaborated with perovskite QD film developer Zhijing Nanotech to produce 500 75-inch QD-enhanced LCD TVs with Zhijing's PQDF films. This is likely to be the world's first commercial adoption of pQD films in the display industry, as the TVs were sold successfully in China and Zhijing hopes to achieve a mass production design win with TCL in 2021

The company reports that the TVs featured a wide color gamut, 147% BT709 - which is higher than most QD TV's on the market, and higher than TCL's original 75M10 TVs. The green Cadmium-free pQD films have excellent optical properties and offer lower cost compared to current QD solutions, according to Zhijing Nanotech.

Researchers use perovskites to create efficient and cost-effective thick OLED devices

Researchers from Japan's Kyushu University developed new OLED devices made by integrating OLED emitters with thick layers of hybrid perovskite materials. The researchers say that such a device structure to enable lower-cost production and better viewing angles in OLED displays.

OLED devices usually use a very thin layer of organic materials, as these are poor conductors, which makes production more difficult and also leads to cavity effects which distorts the emission color. The thick perovskite-OLED hybrid layer (which is around 2,000 nm thick) are more easily processed compared to thin film layers while still being highly conductive.

CSoT demonstrated new OLED display prototypes and technologies at SID DisplayWeek 2019

China-based display maker CSoT demonstrated several new OLED display prototypes and technologies at SID 2019, and this great new video shows these displays in action.

First up is a 31" 4K (3840 x 2160, 144 PPI) AMOLED that was produced using an ink-jet printing process on an IGZO substrate. The peak brightness is 200 nits and the refresh rate is 120 Hz. This seems to be the same panel announced in March 2018 by Joshua Printing Display Technology (established by CSoT and Tianma in 2016). The display has some noticable defects.

Korean researchers develop transparent and foldable perovskite-based LEDs

Researchers from Korea's Ulsan National Institute of Science and Technology developed a new perovskite-based LED (PeLEDs) which are flexible enough to fold and are also transparent. It seems as if these LEDs are similar to OLED devices and provide area-lighting and not point-lighting like inorganic LED chips.
