That’s a fascinating breakdown — it’s wild how many elements are packed into something we carry around every day. I started thinking about the actual display tech more seriously after noticing odd shadows on my screen. I ran an online screen test using this tool: https://allcolorscreen.com/black-screen . It helped me detect a couple of stuck pixels and appreciate how much goes into producing even a simple black background. Honestly, it also made me more mindful of screen strain and how often I overlook the science behind it.
