Where's the demand for it? What's the use case that would make me want one over a traditional LCD or OLED-based device?

What benefit do I get from turning off the backlight? Battery life? Why do I need that when batteries are so cheap/abundant?

It's far easier to just toss in a big battery. For example, the Odin 2 is a handheld gaming device where you can get about 8 hours of battery life playing extremely demanding emulated games like PS2 and GameCube, or play longer than you can stay awake with older games like Super Nintendo or Game Boy Advance.

Or look at your typical PC or Mac laptop, these devices are going the entire workday with the backlight on with no problem.

And of course you'd get even more run time with an external portable battery.

These devices are clever but just make less and less sense over time as our more prevalent technology improves.

Plus, we have more panel choices in the traditional space than ever. Mini-LED devices are fantastic in bright sunlight because the backlight is just so powerful. OLED is incredible for contrast and great color quality and accuracy.

What is transreflexive offering over those solutions?
