OLED display screens began to be commercialized in the 1990s. OLED (Organic Light-Emitting Diode) display technology, also known as organic light-emitting diodes, is a new type of display technology characterized by self-luminescence, wide viewing angle, high contrast, low power consumption and extremely fast response speed. This technology was first discovered by Ching W. Tang in the laboratory in 1979, and the first effective material that could be used as an organic light-emitting diode was discovered by Austen Frachetti and Steven Van Simpson in 1987. This discovery is considered an important milestone in OLED research. However, OLED was first put into commercial use in 1990, when Japan's Pioneer Company launched a car display equipped with an OLED panel, marking the earliest application of OLED screens to the market.
Over time, OLED technology continued to develop and gradually matured, and began to move towards commercialization. By the early 2000s, the application market of OLED expanded to mobile phones, cameras, handheld game consoles and other fields, mainly small-sized panels.
Subsequently, OLED began to mature and gradually achieved commercialization. Especially in the field of mobile phones, the application of OLED screens has gradually increased and become the mainstream of modern smartphone display technology.
In addition, the further development of OLED technology also includes the application of rollable and flexible display technology. For example, in May 2023, Samsung demonstrated a revolutionary 12.4-inch rollable OLED panel, demonstrating the potential of OLED technology in the future display field.
