This Small Business Innovation Research (SBIR) Phase I project will develop a new circuit for controlling micro light emitting diode (LED) and organic light emitting diode (OLED) flat panel displays with variable refresh rate. Variable refresh rate OLED displays are a rapidly growing area for the flat panel display industry and they currently sell for a 79% premium over standard OLED displays. The 2021 market for variable refresh rate OLED displays is currently estimated to be 191 million units with an average selling price of $125, for a total served market of roughly $22 billion. This innovation has the potential for broad societal impact because flat panel displays are now ubiquitous, and variable refresh rate technology enables them to reduce significantly power consumption while improving performance. The intellectual merit of this project stems from the novel pixel control circuit being developed to enable variable refresh rate operation of flat panel displays. This circuit uses amorphous metal non-linear resistor and amorphous metal thin-film transistor devices to reduce leakage current and simultaneously increase speed. The research objectives outlined in the project are focused on the development of a proof-of-concept prototype to demonstrate circuit performance. They include development of a prototype layout, process flow, simulations, as well as fabrication and testing of display prototypes. The anticipated technical result is a simple small-area low-resolution display that demonstrates the feasibility of the technology.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这项小型企业创新研究（SBIR）I期项目将开发一个新电路，用于控制微光发射二极管（LED）和有机光发射二极管（OLED）平板显示器，并具有可变刷新速率。 可变的刷新率OLED显示器是平板展示行业的快速增长区域，目前，它们以比标准OLED显示器的79％溢价出售。 2021年可变刷新率OLED显示器的市场估计为1.91亿台，平均售价为125美元，总服务市场约为220亿美元。 这项创新具有广泛的社会影响力，因为平板显示器现在无处不在，并且可变的刷新率技术使它们能够在改善性能的同时减少显着的功耗。 该项目的智力优点源于开发的新型像素控制电路，以启用平板显示器的可变刷新率操作。 该电路使用无定形金属非线性电阻和无定形金属薄膜晶体管设备来降低泄漏电流并同时提高速度。 该项目中概述的研究目标集中于开发概念验证原型，以证明电路性能。 它们包括开发原型布局，过程流，模拟以及显示原型的制造和测试。 预期的技术结果是一个简单的小区域低分辨率展示，证明了该技术的可行性。该奖项反映了NSF的法定任务，并且使用基金会的知识分子优点和更广泛的影响评估标准，被认为是值得通过评估来支持的。
