Bend light-emitting diode birth Ultra HD screen era is about to open

Recently, according to media reports, researchers from the Chemical Engineering Laboratory of the Federal Institute of Technology in Zurich recently invented an ultrathin flexible light-emitting diode (LED). According to researchers, the flexible LED can emit ultra-light. Pure green light, the researchers also used this fine color to show the three letters "ETH". According to Xiao Bian, Professor Chih-Jen Shih, the head of the research team, was very satisfied with his research and shared his views: “So far, no one has succeeded in producing a pure green light like ours. ”

At the same time, Prof. Shih also said that the research results of this flexible LED will provide a powerful impetus for the production of ultra-high resolution displays for next-generation TVs and smart phones. In the current rapid development of electronic devices, users are increasingly demanding the resolution of electronic devices. Take the television screen as an example. From 1080P to 4K, and the current 8K that TV brands are vigorously researching and developing, each time the screen changes, it reflects the changes in consumer demand for television screens. Insiders pointed out that after high resolution has become the main theme of the electronic device market, electronic device screens must be capable of producing ultra-pure red, blue, and green light to enable the display to produce clearer, richer, and finer color ranges. Adjust the image.

Prior to the development of flexible light-emitting diodes, the industry's technology has achieved corresponding results in achieving the purity production of red and blue light. However, the solid-colored green light has once encountered a bottleneck in technology, and it has been difficult to achieve a technological breakthrough due to visual constraints. Moreover, the change in the green hue is also difficult to distinguish with the naked eye, so the ultra-pure green also becomes very complicated in terms of technical production.

The ultra-thin flexible LED developed by Professor Shih is simple to operate and emits pure green light at room temperature. According to Prof. Shih, the LED technology developed by his team does not require high-temperature environments to operate normally. This will open up new industrial opportunities for ultra-pure green light-emitting diodes that are easy to operate and cost-effective.

According to home network editors, the team used perovskite as a semiconductor crystal for LED radiation in the development of flexible light-emitting diodes. It is the thickness of the perovskite material of less than 4.8 nm that allows the LED material to bend freely like paper. Therefore, the rapid roll-to-roll process of the light-emitting diodes can be realized, which can not only improve the production efficiency but also reduce the production cost.

According to Xiaobian, LED display industry as a semiconductor industry has now entered a new stage of development. This new development process can be summarized from three aspects at the same time. First of all, with the improvement of research and development technology, LED display's environmental protection, high brightness, high definition and other characteristics have gradually been highlighted. Compared with the previous situation of LED products, the LED display has become more practical. specialty. Secondly, in the increasingly mature environment of artificial intelligence technology, LED display screens will also be used on this train to show their talents. Insiders believe that in the near future, intelligent LED displays will infiltrate into homes and office buildings. As well as automobiles and other fields, and bring more advanced services to humanity. Finally, because of its low energy consumption and long service life, LED displays are widely recognized by users. With the improvement of user requirements for screen display, the LED display industry is also facing technological requirements such as technical improvement.

As an industry closely related to human life, the development of LED displays is highly valued within the industry. The development of ultra-pure green light has important guiding significance for the industry to further improve the display effect. Some experts predict that the display world will become clearer and later.
