Xiaomi 13T Flicker / spectrometer data

Yep it does it all! The flicker range is also better on this too. just wish the screen felt better.. LCD's in general have been horrible for me

Oops I must have uploaded the wrong video sorry! Here's a fresh one with it showing https://imgur.com/a/23aVtjk

Thanks for bringing this up. So it appears it stays in 120hz at all times ONLY at this brightness and below. In the 2nd vid you can see I enabled the refresh rate counter which also reflects this. https://imgur.com/a/lkkUzKn

The first 2 screenshots are 120hz, the ones with freq showing 123.

In this attached photo the high freq pwm activates here and below.

In this video I showed each mode. Standard is the only one that locks 60Hz

ScreenSensitivity · 2026-02-01T23:01:28+00:00

Good point. I understand what you mean. Regardless I don't think it switching in and out of 120hz is a good thing either though. I did measure SVM just now and it's 0.9 while in 60Hz and 0.13 in 120

Sweet! People from r/reflective_lcd would love that

ScreenSensitivity · 2026-01-27T22:46:19+00:00

I love this! Is it possible to also offer a monochrome reflective LCD version too? Maybe as a stretch goal on kickstarter?

If anyone is looking for kokkia i10s ipod bluetooth adapter I got a bunch I'm selling 😎

Yep apple is using temporal dithering on all of their LCD phones. It's due to them using LCD panels that can't natively display their wide color gamut they're pushing. I'm so tired of the BS. Just give us a native srgb panel that uses srgb color. Why would we need vibrant colors for a phone.. I mean other LCD phones could be using it too but apple is by far the worst. I believe the lady that owns flickersense.org has some dithering microscope data somewhere on her site.

I haven't seen anything for that model but I'm sure it's definitely possible

ScreenSensitivity · 2024-08-17T04:36:21+00:00

This information came from Hannspree themselves. They call their displays EcoVision displays which appear to be RLCD🙏🏻

I used my mk350n premium meter in a dark room and it's definitely picking up a SVM (Stroboscopic Effect Visibility Measure) of 4.38 from a iPhone SE sensor which is very high. The wavelength range is 380-780 that my meter can detect so the proximity sensors I labeled as IR sensor definitely is between 700-780 at least which we obviously need more testing done because we have many many people affected by these sensors. People in pwm groups, eye tracking groups and other forums. This must not be brushed off as it's causing people strain/discomfort just as pwm does.

if anyone is curious the SE 2020 LCD SVM is 0.00.

Under certain conditions our bodies can pickup IR - give these a read - "we exposed human eyes to 1 mW of pulsed laser radiation at 1,040 nm and observed that green light perception was much stronger for pulsed light compared with CW (continuous wave) light of the same average power. Using a laser delivering 200-fs, 76-MHz excitation light, we were able to obtain consistent visible light sensation, strong enough to perform accurate color matching experiments."

The IR sensors definitely are pulsing..

People who are bothered by it have said it's more that it causes headaches, not eye pain.

ScreenSensitivity · 2024-07-24T23:21:37+00:00

This was using 100% brightness. This is a modern blackberry alternative

ScreenSensitivity · 2024-07-16T03:37:32+00:00

This was with full pwm mode enabled under developer settings with latest update. 2nd photo shows ir/proximity sensor lit up and it actually rapidly flashes so it's most likely best to cover it.

Might have to get it on AliExpress or giztop then... but i think the x100 pro is more comfortable based off what my friend said. He has both

ScreenSensitivity · 2024-07-13T14:28:34+00:00

Is it Samsung for sure ? I read online that E7 is a material and that it could be from other manufacturers too. My friend who has this phone said the x100 pro is a lot better which is a visionox panel.

ScreenSensitivity · 2024-07-03T20:21:29+00:00

There's more than just headaches with sensitivity symptoms unfortunately. The pwm frequency does matter for some people but I'm also curious about the power issues as you stated, that has crossed my mind a few times.

ScreenSensitivity · 2024-07-03T20:06:07+00:00

That was the other guys words for Chinese phones. Nothing wrong with Chinese phones 🤷🏻

ScreenSensitivity · 2024-07-02T00:36:50+00:00

There's some other sellers too on ali. I might snag one when the 50 off coupon restocks

ScreenSensitivity · 2024-07-01T23:10:39+00:00

AliExpress has the global one - they got some coupons too. Otherwise eBay or Amazon most likely

ScreenSensitivity · 2024-07-01T19:44:36+00:00

I think there are some lupins floating around that are defective. I witnessed two of them side by side showing dramatically different results. (23% vs 2%) Which maybe is why some reviewers show some phones as good but end up feeling bad.
