[IEEE 2018 14th IEEE International Conference on Solid-State and Integrated Circuit Technology (ICSICT) - Qingdao, China (2018.10.31-2018.11.3)] 2018 14th IEEE International Conference on Solid-State and Integrated Circuit Technology (ICSICT) - An accurate Current Scaling Circuit for Self-Emissive Microdisplay Driving circuit
摘要： This paper proposes an accurate current scaling circuit which is suitable for OLED or LED microdisplay driving circuit. By adding extra compensated transistor and bias circuit, current mirror transistors’ drain-source voltage (VDS) are almost equal when the new current scaling circuit copy the current to pixel circuit. Simulation results show the deviation error of current scaling ratio in proposed circuit ranges from -0.067% to 0.008% while the deviation error ranges from -9.11% to -1.11% in conventional current-mirror circuit. More accurate current scaling ratio will be benefits for improving the uniformity of the microdisplay’s luminance.

A study of the impact of VLC on the quality of lighting and display – EPSRC
摘要： Dr Wasiu Popoola of the University of Edinburgh talks about his research into visible light communication and shares the results of his latest work examining the underutilised optical spectrum as a potential pathway to wirelessly connect devices. The research investigates the impacts of visible light communication (VLC) on the fundamental properties of energy efficiency, light quality and life expectancy of a light-emitting diode (LED) that is primarily designed for lighting or display. It aims to deliver the required approach for optimising VLC and safeguard the LED’s reliability, durability and emitted light quality.
