To meet the development needs of the optoelectronic market, the 24th China Western International Optoelectronic Expo (CWIOE2026/Western Optoelectronic Expo/Western Optoelectronic Expo) is scheduled to be held in Chengdu from April 27th to 29th, 2026. This expo is jointly organized by Dingnuo International Exhibition (Beijing) Co., Ltd. and other companies, with the participation of Chongqing Jiutian Yidi Exhibition Co., Ltd. It is larger in scale and higher in grade, gathering more new equipment, new products, new materials, new technologies, new processes and new trends in the optoelectronic industry, presenting cutting-edge application achievements, and witnessing the vigorous development and fruitful achievements of China's optoelectronic industry, especially in the western region, since the reform and opening up. The conference is committed to creating a professional platform that integrates business negotiations, international exchanges, and brand exhibitions, providing one-stop solutions for the fields of optoelectronics and related applications.
CWIOE2026, with the theme of "Quality Empowers Bright Innovation", has been successfully held for 23 consecutive sessions. It is the oldest comprehensive annual event in the central and western regions, covering the entire optoelectronic industry chain. As a one-stop efficient procurement platform for materials, devices, equipment, and solutions required for research and development and manufacturing, the conference is also committed to promoting precise business connections, expanding industry networks, and helping to grasp the cutting-edge dynamics and market opportunities in the field of optoelectronics.

Background of Optoelectronic Industry:

The Chinese optoelectronic industry started in the 1990s and has undergone decades of rapid development, forming an industrial system covering the entire industry chain. In recent years, the industry has maintained rapid growth, and optoelectronic technology has been widely applied in key fields such as modern technology, artificial intelligence, economy, military, culture, and healthcare, becoming a pillar industry and the main force of the information technology industry that is competing globally.

As an important agglomeration area of the photoelectric industry in the west, Sichuan has accumulated strategic opportunities from the "three line construction", the western development, the "the Belt and Road" initiative, to the current national positioning of Sichuan as a "strategic hinterland" and promoting the "western relocation of coastal enterprises". Under the multiple support of policies, resources, and technology, Sichuan's optoelectronic industry has flourished and formed a complete industrial system covering optics, optical communication, laser, infrared/ultraviolet, new display/LED, intelligent sensing and robot vision, instrumentation, chip semiconductors, energy/energy storage/photovoltaics, and other categories with a complete chain.

Core highlights of the Western Optoelectronics Expo:

Deeply cultivated for 23 years, service sets the industry benchmark

Since its first event in 2000, CWIOE has been deeply involved in the optoelectronic industry for 23 years, always focusing on service. It is known as a comprehensive event covering the entire industry chain in the optoelectronic field in the western region, and is highly recognized and trusted by industry professionals at home and abroad. To promote the prosperity and technological innovation of the optoelectronic industry in the western region, CWIOE2026 further upgrades its service system and works in both investment promotion and professional audience organization. The organizing committee relies on the resource advantages of the main and co organizers, innovates the activity mode, visits end-user units in advance, goes deep into the front line of enterprises, accurately grasps market demand and development trends, and builds a truly efficient and accurate supply and demand docking platform.

High end forums gather foresight and jointly draw a blueprint for the future of the industry

The conference will hold multiple high-quality and high standard special forums and symposiums at the same time, focusing on the forefront of world optoelectronics, gathering China's core forces, and monitoring industry development trends. Leaders from the Ministry of Science and Technology and the provincial government, representatives from the Chinese Optical Society, and senior executives from well-known optoelectronic companies at home and abroad will be invited to attend the "CWIOE2026" main forum to share forward-looking views, analyze policy directions, jointly explore industry trends, and provide direction for the development of the optoelectronic industry in western China.
