No PWM / No dithering smart phone. ChatGPT says ...

Best Current Option: Bigme HiBreak Pro (E‑Ink Display)

Features a 6.13-inch E Ink screen—completely flicker-free with no PWM dimming and no temporal dithering Android Central.
Comes with Android 14, modern specs, dual SIM, and NFC—practically a fully functional smartphone without the eye strain potential of traditional displays Android Central.
It's the most fail-safe pick if zero flicker and no dithering are non-negotiable.

No pwm no dithering Snapdragon LCD smart phone. ChapCPT says:

Reality Check:

No PWM on LCD Snapdragon phones:
Some Snapdragon-powered LCD phones are known to be PWM-free or have very low flicker due to DC dimming or similar tech.
No temporal dithering:
Very rare to find on LCD smartphones, since many manufacturers use temporal dithering (FRC) to simulate higher color depth and smooth gradients.
Combined “no PWM + no dithering” LCD Snapdragon phones:
Practically almost nonexistent in mainstream devices right now. This is mostly because manufacturers don’t advertise “no dithering” and dithering tests are rare.

Snapdragon LCD Phones Known for No or Minimal PWM

Phone Model	Snapdragon Chipset	PWM Status	Notes on Dithering
Nokia G60	Snapdragon 695	No PWM (tested)	Dithering not confirmed
Realme 9 Pro 5G	Snapdragon 695	No PWM (tested)	Dithering status unclear
Motorola G Stylus 5G (2023)	Snapdragon 4 Gen 1	No PWM above 50% brightness	Dithering unknown
Redmi 12	Snapdragon 685	No PWM reported	Dithering unknown

Why is No Dithering So Hard?

Most LCDs are 8-bit panels but use temporal dithering (FRC) to simulate 10-bit.
This reduces color banding but adds subtle flickering/artifacts.
Few manufacturers confirm or reveal this detail.

Recommendations:

For no PWM, pick phones from the list above or check reviews focused on flicker (like on ledstrain.org).
For no dithering, it's practically impossible to guarantee on LCD Snapdragon phones right now.
The closest you can get is a phone with PWM-free DC dimming and minimal dithering artifacts.

Final Notes:

If zero PWM and zero dithering are critical (especially for eye comfort), the only truly guaranteed option currently is an E Ink phone like the Bigme HiBreak Pro, but that’s not an LCD.

d_balon Moto G Play 2024 has no PWM and no dithering. It's a winner for sensitive individuals.

In my view, Motorola is the top North American mobile phone company today. I know they are owned by Lenovo but I consider North American the Motorola brand.

The G Play 2024 is a low end, entry-level device, and yet it's perfect for all my needs.

The reason I wrote snapdragon is because Mediatek causes heavy dithering (or something like that).

K-Moss ty for the comment.

Motorola G54 5G: LCD display without pwm

And with these instructions https://ledstrain.org/d/3423-success-in-disabling-temporal-dither-how-to/18

you can also eliminate dithering.

I suppose that Dithering and PWM aren't the only problems.
Same important as feature is the backlight illumination panel. New devices are so harsh on eyes with terrible blue intense light.

d_balon

Aquila This! You're right. There has to be safe front or back light panels as well.

d_balon

Aquila Hey. Just to ask, do you know any phone with a safe backlight illumination panel?

d_balon I have my Mate 20 since 2019. Rock solid until now.

Aquila Chatgpt says the Bigme HiBreak Pro phone is the best. While I agree, the sad thing is … their screens break easy. It's not even worth buying a Bigme phone. Read here everyone: https://www.reddit.com/r/Bigme/comments/1m9dbui/buyer_beware_broken_hibreak_pro_screen_means_game/
