This technical report provides a structured overview of contemporary smartphone screen protection materials and systems, with a focus on their mechanical behavior, impact absorption, adhesion, and compatibility with modern display technologies such as OLED and AMOLED panels. The document examines screen protection as a materials engineering problem rather than a consumer product comparison. Key topics include rigid versus flexible protection systems, stress distribution under impact, adhesive interface behavior, optical performance, privacy screen technologies, and real-world usage conditions. Special attention is given to the challenges introduced by thin, curved, and flexible displays. Rather than promoting specific products, this report analyzes material classes and design principles that influence protective performance over time. The goal is to support a realistic understanding of how screen protection systems reduce risk, manage energy transfer, and interact with modern display structures in everyday use. The report is intended for technical readers, product designers, researchers, and informed users seeking a deeper understanding of screen protection technologies beyond surface-level specifications. For applied examples and real-world implementations of contemporary screen protection systems, additional information is available at:https://mobiilikauppa.com
