The display is the part of a smartwatch you look at most, dozens of times a day. Most watches use one of two screen types, AMOLED or LCD, and the choice affects how the screen looks outdoors, how long the battery lasts and whether an always-on display makes sense.
How an LCD screen works
An LCD (liquid crystal display) has a backlight behind a layer of liquid crystals that let light through or block it for each pixel. Because the backlight is on whenever the screen is on, black areas look dark grey rather than truly black, which is most noticeable in a dark room. Power use depends mainly on how bright the backlight is, not on what is shown on the screen.
TFT and IPS are both types of LCD. A good IPS panel can look sharp, with wide viewing angles, and backlit LCDs are common on budget smartwatches. Some sports watches use a different, reflective kind of LCD that stays on all the time and is easy to read in sunlight; this guide is about the backlit LCDs used on most budget smartwatches.
How an AMOLED screen works
In an AMOLED (active-matrix organic LED) screen, every pixel produces its own light. A black pixel is simply switched off, so blacks are truly black, contrast is very high and colours look vivid. "Super AMOLED" is a name some brands use for their AMOLED panels.
Two practical benefits follow. Dark watch faces use less power, because unlit pixels draw almost nothing, and an always-on display (AOD) becomes practical, because the watch can show a dimmed clock with most pixels off.
Like any OLED screen, AMOLED can show burn-in if the same bright image stays on screen for very long periods. Screen timeouts, dimmed AOD faces and changing your watch face now and then all help.
AMOLED vs LCD side by side
| Feature | AMOLED | Backlit LCD |
|---|---|---|
| Blacks and contrast | True black, very high contrast | Dark grey blacks, lower contrast |
| Colours | Vivid and saturated | Depends on panel quality |
| Battery | Dark faces save power | Backlight uses power whatever is on screen |
| Always-on display | Common and practical | Less common on budget models |
| Burn-in | Possible with long-term static images | Not a concern in normal use |
What to check on a spec sheet
- Brightness (nits): higher peak brightness makes the screen easier to read in direct sun. The Fastrack Astor FS2 Pro lists a 1.96-inch Super AMOLED screen with 1000 nits brightness and an Always-On Display.
- Resolution and PPI: more pixels per inch means sharper text and watch faces. The Redmi Watch 5 Lite lists a 1.96-inch AMOLED at 410 x 502 pixels (332 PPI) with up to 600 nits peak brightness.
- Always-on battery cost: the Redmi Watch 5 Lite's listing shows it clearly, with up to 18 days in typical use but 7 days with the Always-On Display switched on.
- Panel type: not every listing names it. The Fastrack Limitless Glide describes an "UltraVU HD Display" (1.85-inch, 240 x 284) without saying AMOLED or LCD, so check the brand's specifications or ask us before ordering if it matters to you.
Which should you choose?
Choose AMOLED if you want an always-on display, rich colours and the best contrast. A backlit LCD is fine if you are on a tighter budget and don't need an always-on display; look for good brightness so it stays readable outdoors.
How to get the best from your watch screen
- Turn on auto-brightness, if your watch has it, so the screen brightens outdoors and dims indoors.
- Set a short screen timeout and use raise-to-wake instead of keeping the screen on.
- On an AMOLED watch, choose a dark watch face to save battery.
- Switch off the always-on display when you need the longest battery life.
- If you add a screen guard, choose one made for your exact model so the touch screen still responds well.
Quick answers
Does an AMOLED screen drain the battery faster?
Not necessarily. AMOLED uses less power on dark content, while bright, mostly white watch faces and the always-on display use more.
Is burn-in a real problem on smartwatches?
It is possible on any OLED screen if the same bright image is shown for very long periods. Screen timeouts, dimmed always-on faces and occasional watch-face changes help keep it at bay.
What does "nits" mean?
Nits measure screen brightness. A higher peak brightness figure means the screen can get brighter, which helps in direct sunlight.
