       In Hubei science and technology supply chain“Link”Down,More and more scientific research results are emerging,Right from“laboratory”towards“production line”。for example,recently,Optics Valley Laboratory、Cooperation with Huazhong University of Science and Technology,Successfully developed high-performance quantum dot photoresist,Achieved global leadership in new display technology。

Lighting、light up,In Optics Valley Laboratory,R&D researchers are stepping up application testing of quantum dot photoresists,Its blue light conversion efficiency is determined by the industry’s30%Raise to near50%,Photolithography accuracy reaches1Micron,Achieved full-color display of the display screen and localized substitution of production raw materials。

Hubei Optics Valley Laboratory、Zhang Jianbing, associate professor at the School of Integrated Circuits, Huazhong University of Science and Technology:“OLED、LCDThis display technology,Its core patents are in the hands of countries such as Europe, the United States, Japan and South Korea.,Many technologies will get stuck,Or pay high patent fees。Through our development of some display technologies with our own intellectual property rights,Can break our current technological passivity in the display industry、This situation of being controlled by others。”

quantum dots,called artificial atoms,Is a semiconductor luminescent material,Widely used in display panel industry。Explore the technical path of quantum dot luminescence,Divided into printing and photolithography。Seeking success from difficulties,past three years,The R&D team of Optics Valley Laboratory chose a method with better accuracy、Better luminous efficiency、Photoresist technology is also more difficult to break through。

Hubei Optics Valley Laboratory、Zhang Jianbing, associate professor at the School of Integrated Circuits, Huazhong University of Science and Technology:“The combination of quantum dots and photoresist,Belongs to a new product form。Because we studied it earlier,So we choose the technical solution of photolithography,Realizing the initiative in new display technologies。”

Seize the initiative,It's a technical struggle,It is also a confrontation of perseverance。The Difficulty of Quantum Dot Photoresist,The first difficulty lies in accuracy,After the fusion of the two,How to get higher photolithography accuracy?Team chooses to add ligands to quantum dots,And the search for this key ligand,After thousands of tests,Haven't been able to break through,Even gave up for a time。

Hubei Optics Valley Laboratory、Zhang Jianbing, associate professor at the School of Integrated Circuits, Huazhong University of Science and Technology:“I've been through a lot of this frustration.,Sometimes I feel very depressed,With this kind of momentum,chew hard bones。If we don't solve the problem,It is very likely that the entire industry will advance very slowly.。At present, our photolithography accuracy reaches one micron.,Belongs to the most leading in the industry。”

technological breakthrough,It’s the first step to break out of the shell,put in the laboratory“fruit”Become what the market needs“Ripe fruit”,In addition to improving photolithography precision,Luminous efficiency is also critical。Based on the Optics Valley Laboratory Platform,A team from Huazhong University of Science and Technology has joined hands with Guangna Jiayuan Company, the first domestic company to produce quantum dots.,design、develop、verify,go hand in hand,Together, they increase the luminous efficiency of quantum dot photoresist to nearly50%。

Hubei Optics Valley Laboratory、Long Rui, a graduate student at the School of Integrated Circuits, Huazhong University of Science and Technology:“The company's quantum dots are more stable,But they lack this theoretical knowledge。After the company provides quantum dots,We improve quantum dots,Then he was immediately sent to Optics Valley Laboratory.,Photolithography by them,See if it meets the standards of our industry。”

at the moment,Based on the advantages of Optics Valley optoelectronic information industry cluster,The team is also accelerating the application of quantum dot photoresist in displays,Strive to put it into use within the year。

Hubei Optics Valley Laboratory、Zhang Jianbing, associate professor at the School of Integrated Circuits, Huazhong University of Science and Technology:“Optics Valley has a very complete upstream and downstream industry in optoelectronic display.,This technology can be pushed to industrialization faster,Use Huaxing Optoelectronics or Huayinxin toLEDgood foundation in,With our quantum photoresist,To realize this kind of display assembly display,I hope to get a dynamic display screen by the end of this year。”
