Oled Display Panel.The world can be a manufacturer of screens. From the TV to the flat screen, and then to the mobile phone, the screen is getting smaller and smaller, and even made WiFI speakers for some time, so that there is no screen. I have a feeling that the screen market is too chaotic, so today let’s sum up the manufacturers who can make screens all over the world.

Ten years ago, if you had DIY desktop computers, you would have been familiar with Philips, BenQ BenQ, TPV AOC, YouPay, Acer Acer, Great Wall and Tsinghua Tongfang. I’m sorry, I’m not talking about these companies today. These brands are just display terminal manufacturers who buy screens from other places to assemble and produce their own displays. In the industry, the monitor is called Monitor in English and the monitor in Taiwan.

If you are a Display driver engineer, you may have come into contact with screens with various interfaces, such as LVDS,MIPI,RGB,SPI,Vby1. You may have adjusted the screens of various manufacturers, such as Lianchuang, Sinopec, Xinli, Helitai, Oufeiguang and other manufacturers, also known as screen makers. Ran Goose, there are hundreds of such companies in Shenzhen. In fact, these companies can not really make the screen, but also buy the screen from other places, plus the display driver IC and backlight, assembled into the above-mentioned LVDS,MIPI and other interfaces, making it easy for machine manufacturers to develop LCD modules that are easy to be mass-produced. What I am talking about today does not include these companies. The LCD module is called LCD Module in English in the industry.

The above two types of manufacturers, whether Monitor or LCD Module, do not have much core technology, and the threshold is very low, so as long as they have money, basically anyone can do it.

Next, I would like to talk about the real protagonist, but also the suppliers of the above two types of manufacturers-LCD panels, English name Panel, jokingly known as glass, can make glass is the real core technology. There are only a few places in the world that can make glass:

Samsung, LG, Innolux, Sharp, AUO, JDI, BOE, Huaxing Optoelectronics, Tianma Microelectronics, CLP Panda, Zhonghua Picture Tube, Longteng Optoelectronics, Huike.

(need to be clarified here, Lance Technology, Bourne Optics and Gorilla Corning also make glass. the glass here does not refer to the display screen, but only the protective glass on the display screen.).

Simply go through these manufacturers.

Samsung, LG, there is nothing to say, the LCD panel is absolutely the leader, note that the Chinese name of LG is LG Electronics.

Qunchuang: the English name is Innolux, a company owned by Foxconn, which acquired the famous Chi Mei Electronics in 2010. Chimei screen was also famous at that time, and the name of Qunchuang was still used after the merger.

Sharp: the English name is Sharp. It was originally a Japanese company and an Apple supplier. Xiaomi prided itself on using the same screen supplier as iPhone. Later, due to poor management, it was acquired by Foxconn in 2016 and should now belong to a Taiwanese company. Sharp not only makes screens, but also has Sharp TV, but Sharp TV does not necessarily use Sharp’s screen.

Youda: the English name is AUO, a major manufacturer of LCD panels in Taiwan and a supplier of Xiaomi mobile phones. The name Youda actually comes from Japanese. SHE has a song called “Friendship is above, lovers are not satisfied”.

JDI: Japanese manufacturer, whose full name is Japan Display Inc, has a long history. Jointly established by Sony, Hitachi and Toshiba in 2011, it is committed to the production and research and development of small-size displays. It’s also an Apple supplier. JDI currently only makes mobile phone screens, not large TV screens.

Beijing Oriental: its English name is BOE,Best On the Earth. State-owned enterprises, the leader of domestic LCD screens, is already the first company in the world in LCD panel shipments. BOE was originally called Beijing Dongfang Electron Tube Factory, but it only made some electronic components. In January 2003, BOE successfully acquired Hyundai’s TFT-LCD business of Korea for US $350 million and acquired all Hyundai’s intellectual property rights (including TFT-LCD application technology, design technology and manufacturing technology, etc.) and team, thus entering the LCD panel industry. At present, factories have been set up all over China: Beijing, Suzhou, Hefei, Chengdu, Mianyang, Chongqing, Fuzhou, Ordos. Local governments are scrambling to welcome BOE.

Huaxing Optoelectronics: the English name is China Star and the acronym is CSOT. It is a joint venture between TCL and the Shenzhen Municipal Government. TCL directly owns 85.71% of Huaxing Optoelectronics. It is currently the most profitable company under the TCL Group. In the past, it used to mainly make TV screens, but now Wuhan Construction Factory has also begun to make mobile phone screens.

The management of Huaxing Optoelectronics is mainly from Taiwan, and the following is excerpted from “Light change”:

In the leadership of Huaxing Optoelectronics, Senior Vice President Kim Hung-sik served as Executive Vice President of LG LCD production Technology Center headquarters, responsible for the construction of LG lines from 3.5th generation to 7.5th generation; Vice President Kingdom and former factory director of Qimei and Deputy General Manager of Longteng Optoelectronics are factory construction experts; Wang Xinglong, vice president of Huaxing, once served as senior associate of Youda, laying the foundation for quality management of Youda.
