2 About company Company history Company Motto Create a company with dreams, which considers my future self with responsibility. With the know-how in semiconductor assembly accrued over 11 years since its foundation in 1998, our profits have been increasing as a professional company specializing in the production and sales of electronic communication devices and parts. With patents in parts such as the power IR LED, we have strengthened our capabilities in semiconductor (i.e., photo sensor) and core information and communication parts business, realizing stable growth and profitable management. Our stable management and excellence in quality of our products have been approved by Samsung Electronics, a Korean conglomerate, which has registered us as their primary vendor. Our LED lamps have been installed in the Samsung Electronics white goods such as washing machines and refrigerators. Also, the superiority of our products have been approved by the local Samsung factories, and this gave us the opportunity to reap profits from exports. Although continued increase in profits and sales capacity has provided Yoosol Electronics Co., Ltd. with the opportunity to grow, but the company has experienced limitations in expansion with just domestic business and sales. Therefore, under the motto international export is the future growth engine, we have expanded the business area into the LED lighting field using the superiority of the LED lamps, beginning Under the philosophy that the source of growth is concentrated R&D and continued international pioneering, we were able to focus on new business marketing overseas, and currently, we are providing service and goods to the US, Central and South Americas, Europe, and Asia. With more aggressive sales activities, we promise to provide goods and services to our clients to meet their needs, to become the world s best in the industry. Thank you.
