Display manufacturer

[MechaNarutoSucks]

Hi again.

This time I'll touch into a very frustrating matter for the new users of poco f1. because of how the hardware test app on the new miui versions don't show the manufacturer of the lcd panel.


From what I've asked my friends it seems that the global versions ship with low quality displays such as ebbg panels and the models which got launched at first have the better tianma panels.

Its been like this for 3 of my friends 2 of them had the tianma panel because they were using the initial models and one of them had the global version.

So if you were thinking of overclocking your lcd you should choose the 65 hz option if you have the global version because ebbg panels and others are not that good in terms of quality.

To be honest ive tried the 65hz even then it had some weird glitch artifacts on the screen so i would advise you to stay at 60hz.

And if you are using the global version you should stay updated in terms of touch drivers and if you are not using the global try to use the old drivers.

Hope this helped you.

I have NVT screen and i never had problems even with 70hz, batch from 11
Also never use old driver cuz that's ruining your screen

my pocophone F1 Global is a 2018/10 Lot and use Tienma fhd nt36672a display... never heard of other display type...

Pocophones have been supplied with 3 LCD panels - EBBG, BOE and Tianma.

From what I've gathered so far- Tianma are superior since these are most likely LTPS IPS panels, while BOE/EBBG are regular IPS panels. Meaning - Tianma panels are consuming much less energy.
This is why some of the Pocophone users can easily surpass even 16 hours of SOT (without gaming, just watching youtube, movies, listening to the music, etc. with Wifi AND LTE data always enabled) while others can't get even past 8-12 hours (BOE/EBBG panels) in pretty much the same use-case scenarios.

You can find some Pocophone panel comparisons on youtube. In these videos EBBG has a yellowish tint (whites are yellow/brownish) and is overall darker, while BOE and Tianma are much brighter and also have much better color reproduction. Also - on these videos Tianma panels have no issues when it comes to touch detection on the edges, while BOE have some issues near top/bottom of the screen.

That's also why you can find conflicting opinions when it comes to the screen of Pocophone, in different reviews that are available on the internet. Some of them say that the screen of the Pocophone is mediocre at best, while other say that it's very good in its class, for the price. There are also different numbers when it comes to the measured brightness.
These reviewers got different Pocophones with different panels.

By going through the kernel notes of different custom kernels on XDA forums you can gather that Tianma screens can be overclocked up to 70 Hz, while BOE/EBBG are more limited (up to 65 Hz).

You've said that Tianma panels have been supplied initially and are not being supplied anymore. I can't confirm that information. My Pocophone (with Tianma panel) was manufactured in 2018-10. You can find the date at the bottom right side of the sticker which is located at the back of the original phone box.

When it comes to checking the panel model - you should be able to do that by going into: Settings->About phone->Full specification. Then touch the "kernel version" several times.. It should get you into the diagnostic mode.
There you should be able to pick the first available option - "Check version info". Next - just scroll down at the bottom and there you will find "LCM Information", in my case it says: "dsi tianma fhd nt36672a video display"

Just to add more recent infos My poco 6/128 Global Version manufactured 01/2019 have Tianma panel, perfect backlight but I can say sometimes fails when trying to type fast, it's not a problem with edges but seems more a problem with touch input recognition that is not uniform among the panel

In the new versions of the miui the option to see it is gone the only way to figure it out is by using root

And when it comes to your answer I've never said anything like
" this is the truth "
So this is just a conclusion I've came up with to help others who insist on not rooting.

From the results of my investigation this was the conclusion I've ended up with.

And if you've read it carefully you can see that i've said that me and my friends all had the global version. So this is just a conclusion based on me and my friend's experience.

Edit: mine was manufactured in 2019.01 just you let you know.

So you have 2019.01 and have problems? What screen you have? I have 2018.11 and never had problems even with 70hz

I haven't said that you did. Just that I can't confirm that Tianma panels have been used only initially (Tianma panels are also being used in the new Redmi Note 7) .
And I agree - it's good to exchange the information, by having more of these comments coming from different Pocophone users, we can get a better view on how Xiaomi is operating when it comes to using very different phone components in the same phone model.

I'm not trying to discourage that, it's just the opposite.

The other phones, like Xiaomi Redmi 6 are also using different panels from EBBG, BOE and Tianma.

Edit: mine was manufactured in 2019.01 just you let you know.

You can also try to enter: *#*#64663#*#* using your dial pad. It should bring up the same QC test menu. Check it out.

 

[mastermoon]

Use Device HW info app to check the panel manufacturer..

Nice write-up, all good to know - surprised that nobody else has liked the post. I checked and found I have a Tianma display so yay (imported mine on launch day, dunno about manufacture date).

Also concretely puts to rest the "But I don't have touch problems in PUBG so it's not a design flaw but might be software issue" arguments.

How u change hz of display?

You need to flash one of the custom kernels

Like i said in the new versions of the miui specifically beta versions the qc test menu doesn't show the display info like i said I've rooted my device and loaded pe for my taste and have a custom kernel I've just wanted to give my opinions on it for the users who want their devices to stay unrooted like you said. And I've said it before but I'll say it again i have the ebbg panel it's not like I'm not satisfied. For the price I'm more than satisfied with the poco.

For the unrooted users the app doesn't show the panel info.

Like you said the touch problems are software related some users reported that the new versions of the miui/firmware with the new touch drivers had problems such as touch lag multi touch not working and recent reports from the users are good poco team has kept their promise and fixed the issues so it should be okay for the users to flash the new firmware/miui updates without worrying.

And from what you are saying my conclusion got stronger the ones from launch mostly have the tianma panels and I'm gonna say it again this is not going to be true for every launch manufactured poco but if you are frustrated you can probably rest relieved because most likely you have one of the best panels poco f1 has shipped with.

@CosmicDan And thx for the reply I'm happy that users got what they wanted.

Edit: New reports from my friends show that the newly manufactured ones mostly have the nvt panels instead of tianma especially for the 64gb versions all the low quality panels stay the same.

 

[MechaNarutoSucks]

I too have an nvt screen. How's it in quality as compared to tianma?

It's generally same.

 

[joetong]

Tianma is LCD display ; NVT is touch panel

I am not using the Poco phone but the redmi note 7. I have the same tianma panel as some of the users of f1 do.
Seems to be also facing a touch latency problem. Any fixes yet other than custom roms.?
