报告摘要:
Display technology not only requires continuous exploration in material innovation, but more importantly, disruptive innovation in device structure can truly realize the vision of "Freedom to Operate" FTO. With the rapid development of OLED display technology towards large size, ultra-high definition and intelligence, higher requirements are placed on the integration and performance of pixel circuits. This report highlights two disruptive display device designs that have opened up new paths for the future development of display technology. Firstly, we have proposed a ferroelectric memory organic light-emitting transistor (Fe-OLET) that integrates switching, light-emitting, and storage functions. This original device structure design not only significantly simplifies the pixel circuit structure and increases integration density, but also reduces the cost of technology application and display product development through the FTO strategy, making full use of existing OLED material technology. Secondly, we introduce an AC-driven organic light-emitting tetrode with an open electrode structure. This device subverts the design paradigm of traditional closed electrodes, and forms a highly open and flexible device structure through the planar electrode layout. This innovation in the device structure not only improves the designability and adaptability of devices, but also brings new application opportunities and imagination to cutting-edge fields such as human-machine interface, flexible display, and smart devices. The two original display devices presented in this report together provide a new direction for the global innovation and application of display technology.
