According to Hubei Daily, the first domestic new type of display printing equipment produced by Wuhan Guochuangke Optoelectronic Equipment Co., Ltd. (hereinafter referred to as "Guochuangke") is entering the testing stage and is expected to be put into use within this year.
It is reported that Guochuangke is located in the Optical Valley Intelligent Manufacturing Industrial Park, East Lake New Technology Development Zone, Wuhan City. It was jointly funded and established by TCL Group, Huazhong University of Science and Technology, Wuhan Digital Design and Manufacturing Innovation Center Co., Ltd. in December 2020, and Chen Jiankui from Huazhong University of Science and Technology served as the general manager.
Guochuangke focuses on the key common technologies and core equipment of new display printing and manufacturing, and develops large-area, high-precision, high-efficiency OLED, quantum dots, Micro LED and other related display devices. TFE and other series of inkjet printing equipment, as well as AOI measurement and defect detection equipment and other products.
On August 12, 2021, the new display printing manufacturing equipment project of Guochuangke was officially signed and settled in Wuhan Optics Valley Intelligent Manufacturing Park. Realize the independent and controllable development, production and application of new display manufacturing key equipment.
Chen Jiankui introduced that the display panel is composed of a substrate and a luminescent material. At present, the mainstream evaporation process used to manufacture the panel is to evaporate the luminescent material onto the substrate. The material utilization rate is low, and it is not suitable for large screens. The company piezoelectric jet printing technology is similar to ink jet printing, with fixed-point jet printing of luminescent materials, the material utilization rate is as high as 90%, and the screen-making cost is greatly reduced.
It is reported that the technical team of Guochuangke has been deeply involved in the field of panel functional layer film forming process, technology and equipment development for more than ten years, and has obtained nearly 60 national invention patents and software copyrights. The 200×200 type new display jet printing equipment has passed the process test and device preparation and lighting verification in the National Printing and Flexible Display Innovation Center.
At present, Guochuangke has completed the RD and design of G4.5 generation OLED display panel production-type inkjet manufacturing equipment, and will continue to tackle the development of large-size OLED display panel mass production equipment, as well as new technologies and new technologies for QLED and Micro LED manufacturing equipment. Product development and market development.
