Shortly after the opening of the Expo, in the global youth technology innovation tour pavilion on the Huangpu River, Japan's Sony and Germany's Merck showcased the latest OLED display technology, OLED notebook computers, which can be rolled into a shaft when not in use. On the screen, half of the space can be virtualized as a keyboard, or all of them can form a tablet touch computer.
Using this technique, the MP4 can be rolled into a wristband. In the Japan Pavilion, which is leading the technology in the Expo Park, all OLED lighting is used.
According to industry insiders, traditional LEDs use inorganic compounds, while OLEDs use plastic organic molecules as luminescent materials, and the particles are smaller and invisible to the naked eye. More critically, the OLED itself can emit light, does not require a backlight, uses different substrate materials, and has curlable physical properties.
However, as a new technology, there are still many technical problems that need to be improved, such as short life span and poor oxygen barrier.
It is understood that Yangzhou has already targeted the technology and has done a lot of homework. Yangnong Chemical has started research on OLED technology and has entered the trial phase.
