When choosing materials for screens, their ability to handle light plays a big role. This includes how they absorb, reflect, and bend light.

Absorption
Materials need to soak up light well so that the colors on the screen really pop. Take OLED screens, for example. They use special organic materials that can absorb specific light colors. This helps make the colors look accurate and bright. However, if a material absorbs too much light, it can waste energy. So, it's important to find a good balance for the best performance.

Reflection
How much light a material reflects is also very important. This affects how bright and clear the display appears. If you’re in a bright room, materials that reflect a lot of light can help you see the screen better. Sometimes, special coatings are added to improve how much light is reflected while still keeping the picture quality good. Think of mirrors or certain LCD screens that use these coatings to work well in various lighting conditions.

Refraction
Refraction is about how light bends when it goes through different materials. This affects how clear the image is and how the screen is designed. For example, materials like glass or plastic are chosen based on how they bend light. This bending helps in making filters and lenses in the display, which leads to a better experience for the user.

In summary, the way materials absorb, reflect, and bend light is key in choosing the right ones for display technology. This influences how well the screen works and how it looks. Picking the right mix is crucial for creating high-quality visuals that meet what users need in any situation.
