Yeolight Technology was spun-off Visionox in May 2015 to act as an independent company focusing on OLED lighting. The company produces and supplies OLED lighting panels.
In November 2016 Yeolight introduced its first OLED lamp, using panels acquired from LG Display. Since then the company started to produce its own lighting panels, and in 2017 announced it is targeting the automotive market (among other markets).

China-based Yeolight demonstrated new OLED lighting taillights designs at the Automotive Lighting Exhibition in Shanghai. In the video below you can see some of the various prototypes:
And in the photos below you can see some others. These are interesting prototypes. Some of these have been developed in collaboration with automotive makers, for example Geely-owned Zeekr.
In May 2022 we reported that China-based OLED lighting developer Yeolight Technology is starting to build a 4.5-Gen OLED lighting production line, in Huaibei City, Anhui Province, China. The company is now starting to move in and install the first production equipment. The total equipment cost is estimated at 800 million Yuan (about $111 million USD).
Yeolight says that the new fab, when complete, will have a capacity of around 7 million panels in a year, or 1.2 million automotive lighting modules (probably referring to rear light modules). This will be the world's largest OLED lighting fab, when complete.
Yeolight showed several new OLED lighting taillights designs at the Automotive Lighting Exhibition in Shanghai. In the video below you can see the various prototypes.
Some of these displays seem very impressive, with a large amount of panels. The full-length taillights have 1,434 OLED panels in different shapes and sizes, and support multiple dynamic effects.
China-based OLED lighting developer Yeolight Technology is starting to build a 4.5-Gen OLED lighting production line, in Huaibei City, Anhui Province, China.
The total investment in this new fab will reach 2 billion Yuan (around $300 million USD). Construction at the site has already began. When ready, the fab will have a yearly capacity of around 7 million OLED panels.
China-based OLED lighting developer Yeolight Technology published two new videos that demonstrate the company's latest OLED technologies. You can see the company's segmented triangular based modules, and also a module based on flexible red panels:
The triangular-based OLED, which the company refers to as digital OLED taillight (it reminds us of Audi's technology, produced by OLEDWorks, which goes by the same name), uses modules that use 50 segments (each a right-angled triangle with an area of 19 mm2). We do not have any information on the flexible panels.
China-based OLED lighting developer Yeolight Technology announced that its OLED panels were adopted by Hongqi in its latest H9 flagship sedan which is now being launched in the Chinese market. Hongqi is owned by FAW Car company and is actually the oldest Chinese passenger car brand.
The H9 uses 4 red OLED panels in each module. The panels are 131x32 mm in size and have 5 segments each. The color coordinate is CIY(0.69, 0.31).
Yeolight Technology (which was spun-off Visionox in May 2015) developed candle-shaped transparent OLED lighting panels. The segmented panels have five different lighting panels each with its own brightness. The total size is 11.26 x 26.26 mm (with a thickness of 1.05 mm).
Yeolight tells us that these new OLED candles has been developed for a customer that will soon ship its final product to the market. The panels are now in production.
The light emitting area is 13 cm2 and the whole panel weighs just 1 gram. Yeolight says that the panel uniformity is over 90%. The panel uses a "special organic polymer" that Yeolight developed and used new materials, package structure and processes in order to improve the lifetime and durability of its new panel.
Yeolight Technology (which was spun-off Visionox in May 2015) developed a new bright Amber OLED panel. The panel's size is 85x85 mm (active area 76.5x76.5 mm) and its color temperature is 2000K-2600K. The efficiency is >70 lm/W at 2,000 cd/m2 brightness. The lifetime is over 20,000 hours.
This new panel is still a prototype - but Yeolight says it can already be mass produced at the company's 2.5-Gen production line.
China's Yeolight has opened an OLED lighting exhibition center, located in GU’an city Hebei province, China. Yeolight says that at 431 sqm, this is the largest OLED lighting gallery in China. Most of the OLED panels on display are produced by Yeolight, but some are made by LG Display.
The exhibition center has six different "experience" areas that demonstrate a range of OLED installations, including commercial lighting, interior lighting and automotive lighting. The center also includes explanations of OLED lighting technology and fabrication processes.
