Review of Display Technologies Focusing on Power Consumption

Producción CientíficaThis paper provides an overview of the main manufacturing technologies of displays, focusing on those with low and ultra-low levels of power consumption, which make them suitable for current societal needs. Considering the typified value obtained from the manufacturer’s specifications, four technologies—Liquid Crystal Displays, electronic paper, Organic Light-Emitting Display and Electroluminescent Displays—were selected in a first iteration. For each of them, several features, including size and brightness, were assessed in order to ascertain possible proportional relationships with the rate of consumption. To normalize the comparison between different display types, relative units such as the surface power density and the display frontal intensity efficiency were proposed. Organic light-emitting display had the best results in terms of power density for small display sizes. For larger sizes, it performs less satisfactorily than Liquid Crystal Displays in terms of energy efficiency.Junta de Castilla y León (Programa de apoyo a proyectos de investigación-Ref.

Sustainable User Interface Generation for Digital Devices: A Case Study

The internet has become an integral part of people’s lives. However, any digital activity results in energy consumption and greenhouse gas emissions, which are the prime drivers of global warming and climate change. The environmental cost calls for the practice of sustainable web design or green human-computer interaction. While there is substantial research on ways to reduce the energy consumption of the back-end information systems, such as data centers, few studies focus on the front-end information systems, such as web design. This study aims to analyze the impact of web design on energy consumption by conducting a case study on an institutional website. A set of major web tracking and performance metrics tools will be adopted to collect data on energy consumption, web performance optimization, web design, and user experience. Descriptive analysis of the data will help generate actionable insights into environmentally friendly user interface design strategies for digital devices.Master of Science in Information Scienc
