Everdisplay Optronics (Shanghai) Co., Ltd.

Everdisplay Optronics (Shanghai) Co., Ltd. (EDO; Chinese: 上海和辉光电股份有限公司) is a Chinese manufacturer of AMOLED semiconductor display panels headquartered in Shanghai. Founded in October 2012, the company specializes in the research, development, production and sale of high-resolution AMOLED panels. It is one of the earliest domestic Chinese manufacturers to achieve mass production of AMOLED displays, having brought its 4.5-generation AMOLED line into mass production in December 2014, which broke the long-standing monopoly of foreign manufacturers in the AMOLED industry. The company operates two modern AMOLED production lines: a 4.5-generation line and a 6-generation line. The completion and production ramp of the 6th-generation AMOLED line significantly raised Everdisplay's enterprise level. Everdisplay focuses on medium- and large-size display products, positioning itself as a pioneer and leader in China's medium-size high-end AMOLED display segment. Its panels are used in mobile devices, laptops, automotive displays and aviation applications. Everdisplay listed on the Shanghai Stock Exchange STAR Market (科创板) on May 28, 2021, under stock code 688538. The IPO proceeds were mainly used to expand the capacity of the 6th-generation AMOLED production line from 30,000 large substrates per month to 45,000 large substrates per month, a project listed as a major construction project of Shanghai for 2022–2025. The company has a registered capital of 13.809 billion yuan. It is recognized as a high-tech enterprise, a national intellectual property advantage enterprise, a State-owned Assets Supervision and Administration Commission (SASAC) 'Science and Technology Reform Demonstration Enterprise', and a green factory demonstration unit, and has won the 'Shanghai Intellectual Property Innovation Award'. Everdisplay serves the national strategy with a forward-looking focus on AMOLED technology, emphasizing medium- and large-size display products. Its corporate spirit is described as brave, honest, wise and modest. The company aims to become a benchmark in the AMOLED display panel industry in the new era. In recent years it has achieved mass production shipments of Hybrid AMOLED displays (March 2024) and Tandem AMOLED displays (June 2024), and its fundraising project began mass production in March 2025.
