Mitsubishi is a "community" that consists of a multitude of independent companies involved in a wide range of markets including automobiles, plastics, electronics, hotels, banking and more. Several of these companies were involved with OLEDs, but most (not all) of Mitsubishi's OLED projects were cancelled.
Mitsubishi Chemicals was working towards OLED materials together with UDC. They had also entered the OLED Lighting market together with Pioneer in 2010 and were selling OLED panels under the Verbatim brand (Verbatim is owned by Mitsubishi Chemicals), but the OLED lighting business was later disbanded. The company developed (in collaboration with researchers from Keio University) a new method to accelerate the design of OLED materials, using a combination of classical computing with quantum computing.
Mitsubishi Heavy Industries aimed to produce OLED display panels back in 2007, but that project never saw the light of day.
Mitsubishi Electric was producing the world's largest OLED display, the Diamond Vision OLED, modular displays that are made from 128x128 PMOLED tiles. The first Diamond Vision OLED was installed in 2010 at Merck's Material Research Center, and several others were announced, but it seems that product line has been abandoned. Mitsubishi Electric also had an extensive display IP portfolio (over 1,200 patents related to LCD, OLED and other display technologies) - which it sold to IPValue in 2024.

Mitsubishi and Pioneer to start mass producing color-tunable OLEDs made using a wet-coating process
Mitsubishi and Pioneer launched bluelight-less OLED lighting panels
Mitsubishi doubles the lifetime of their wet-coating OLED lighting panels
In early 2014, Pioneer and Mitsubishi Chemical announced that they began to mass produce OLED lighting modules made with a "wet coating system". Soluble OLED processes should offer a great production cost reduction - but Mitsubishi's panel suffered from limited lifetime (15,000 hours).
According to a new report from Japan, Mitsubishi managed to double the lifetime, and their newest panels offer 30,000 hours. This was achieved by new longer-lasing OLED materials and a different device structure. Mitsubishi already shipped panel samples to lighting equipment makers and will setup up their marketing effort soon via their Pioneer JV (MC Pioneer OLED Lighting).

Pioneer and Mitsubishi begin to mass produce cheap wet-coated OLED lighting panels
Pioneer announced that they began to mass produce OLED lighting modules made with a "wet coating system". The production technology was co-developed by Pioneer and Mitsubishi Chemical. The panels will be distributed by MC Pioneer OLED Lighting Corporation.
The two companies currently produce a single module that is 92.4 x 92.4 mm in size (active area 76x76 mm) and 4.3 mm thick. It weighs 42 grams. The color temperature is 2870K and the maximum luminance is 3,000 cd/m2. Unfortunately they did not reveal the efficiency and lifetime of this OLED.
