Yeolight Technology

Last month China-based Voyah announced a new international all-electric SUV called the Zhiyin, that includes several innovative technologies. The taillights of the car are OLED lighting based, with 33 individually controlled OLED units on both the upper and lower sections, creating unique light patterns. We assumed that Yeolight is the OLED panel supplier, and indeed now the company confirmed that.

In addition to the OLED taillights, the Zhiyin will also an AMOLED display - a "curved sliding screen" that can "slide to accommodate different user needs". While this is not confirmed, we assume that this is a similar display to the one Hongqi just revealed yesterday - a sliding rollable 14.2" AMOLED panel produced by Visionox.

China-based Voyah announced that it will launch an international all-electric SUV called the Zhiyin next month. The Zhiyin was specifically developed for the global market, with two distinct front-end designs and several innovative technologies.

The Zhiyin will sport customizable OLED taillights, consisting of 33 individually controlled OLED units on both the upper and lower sections, creating unique light patterns. It is not clear whether this is optional, or whether it will come standard in all of the Zhiyin models. We assume that Yeolight is the OLED panel supplier, but we're not 100% sure.

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.

Yeolight Technology (which was spun-off Visionox in May 2015) developed a 0.1 mm flexible OLED panel. This is a red OLED panel that is specifically designed for automotive applications.

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.
