MIP display: why Garmin watches last for weeks

MIP (memory-in-pixel) is a type of LCD in which every pixel has its own tiny memory and can reflect outside light. Such a screen is easy to read in sunlight and uses very little power.

A MIP display reflects the sun and stays readable

In plain words

AMOLED is like a torch: it shines by itself and is bright, but it drains the battery all the time. MIP is like a small mirror reflecting the sun: the brighter it is around you, the better you can see it, and it needs almost no energy. But in the dark the mirror shows nothing without a backlight, and its colours are pale.

How it works

Each pixel has built-in memory, so the screen does not need constant redrawing.
The image is formed by reflected outside light.
Energy is only spent on changing pixels.
In the dark, a backlight turns on.
There are fewer colours and less contrast than AMOLED, but readability in sunlight is excellent.

A MIP watch for long hikes

Where you'll see it

MIP is used in sports and outdoor watches (Garmin Instinct, fenix Solar, earlier Forerunner generations), bike computers and some fitness trackers. In our watch comparisons it shows up in the Display row.

Does it matter when buying

Yes, if battery life and readability in sunlight matter to you: hiking, running, cycling, weeks away from a socket. If your watch is a smartphone accessory and you love bright watch faces, go for AMOLED. I would pick MIP for extreme hikes and AMOLED for everyday wear.

Myths

Myth: MIP is outdated technology. Reality: It just has a different purpose: battery life and sunlight, not brightness.
Myth: You cannot see anything on MIP at night. Reality: There is a backlight; it is just less bright than AMOLED.

FAQ

How is MIP different from E Ink?

Both are reflective, but MIP refreshes faster and suits watches better.

Why do MIP watches last so long?

The screen uses almost no energy when the image is not changing.

Can MIP be combined with solar charging?

Yes, MIP watches are often the ones with solar panels.
