Here are Semiconductor Energy Laboratory's latest foldable and high-density OLED displays

Japan's Semiconductor Energy Laboratory (SEL) is developing several exciting OLED technologies, and the company demonstrated its latest panels at SID DisplayWeek. The recently published video below shows the company's OLED technologies shown at the event:

First up is the world's smallest 8K display, a 8.3" OLED (1058 PPI) with a resolution of 7680x4320. The panel is based on a white OLED with color filter architecture and SEL's proprietary CAAC-IGZO (c-axis aligned crystalline In-Ga-Zn-O) backplane material.

Here is Panasonic's wooden-cabinet transparent OLED prototype

In April 2019 Panasonic unveiled a transparent OLED TV prototype housed in a wooden cabinet. Here's a nice video showing the display in action:

Panasonic has been showing transparent OLED display prototypes and concepts since 2016. This specific prototype was designed by Scandinavian based designer Daniel Rybakken in collaboration with Panasonic Design Kyoto.

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.

Visionox shows new foldable, flexible and automotive OLED Displays at SID 2019

China-based OLED producer Visionox has demonstrated several new OLED technologies at SID DisplayWeek 2019 last month, and the following great video shows the company's impressive booth and displays.

First up is a foldable OLED display that can be folded inwards and outwards. The panel's folding radius is 5 mm, and Visionox says that it can be folded over 200,000 times. The company did not disclose the exact size and resolution, though.

BOE demonstrates a 20:1 AMOLED shelf-label display prototype

BOE demonstrated a new AMOLED display that has a unique format - a 20:1 display (1209×63 mm) with a resolution of 3840×160 and relatively small bezels.

These kind of displays can be used for electronic shelf label applications - a field traditionally catered for by e-paper or E Ink displays due to their high efficiency and non volatility. E Ink displays are highly suited for these signage applications - but OLEDs can offer much higher image quality and colors so could suit some applications.

Lenovo demonstrates a foldable 13.3" Windows laptop

Update: LGD confirms it is supplying the 13.3" foldable OLEDs to Lenovo's prototypes.

Lenovo demonstrated a prototype foldable ThinkPad laptop, that features a 13.3" foldable OLED display. Lenovo says that it developed this device for over three years, and hopes to launched a commercial one in 2020.

The reporters at The Verge really liked the device, but noted that the hardware is clearly not finished - the folding mechanism for example did not feel sturdy (and we all know this is critical in a foldable device) and the display itself suffers from "remarkably poor viewing angles".

A visit to LG Display's Paju OLED production hub and show room

On March 9th, LG Display's promotion team kindly invited us to a tour of LG's "Display City" in Paju, Korea. The display complex houses about 20,000 employees, and is highly impressive. It was a pleasure to get the opportunity to see it.

The first thing one notices is the new P10 10.5-Gen OLED TV fab building - which is the largest building in Paju. The P10 OLED TV fab is not complete yet, but according to reports LGD will be ready to start installing the equipment soon.

OLED displays and lighting in Seoul - March 2019

In early March we conducted a 10 day trip to Seoul, to attend the OLED Korea 2019 conference (and visit some local display companies).

Visiting Seoul is a great chance to witness some beautiful OLED installations - LG Display has been deploying its OLED lighting and display solutions across town in businesses and tourist attractions. Retail stores of course were showing the latest smartphones by Samsung and LG - all of which adopt high end flexible AMOLED displays.

TCL shows foldable OLED devices prototypes at MWC 2019

China-based TCL has unveiled a new foldable OLED phone prototype at MWC 2019. The device uses a 7.2" 2048 x 1546 AMOLED display that folds inwardly (in a similar way to the Samsung Galaxy Fold). TCL's device, however, is a prototype and not a product.

TCL is both a smartphone maker and a display producer. This device was demonstrated by the smartphone maker arm - and we are not sure whether it uses a foldable OLED produced at TCL's own OLED lines (CSoT's T4 6-Gen flexible OLED line in Wuhan should enter production soon) or whether the panel is produced by Samsung, BOE or Visionox.
