View of nature of science and technology (VNOST) was used to explain the phenomena of science and technology, and to explore the relation of science, technology, and society. Organic light-emitting diodes (OLED) technology was one of the latest technologies that contain the Nature of science and technology (NOST) aspect and can be used to improve the chemistry learning process. The purpose of this research was to validate the development of didactical design of OLED. The research method was the Model of educational reconstruction (MER). Validation involves 5 experts (lecturers) as validators using a validation sheet contains indicators of learning achievements, student activities, predictions of pre-service chemistry teacher responses, and the anticipation of educators. Validation was analyzed using the content validity index (CVI). The results showed that didactical design of OLED based on VNOST was appropriate for use in chemistry lectures that connecting the chemical concepts with the latest technology where the CVI value was 0.95.
