I bought a mi 11 lite 5G a few days ago, and it's a great phone. On the other hand, I thought the screen was not great, I felt like everything was blurry compared to my old Samsung A5 2016 (also having a 1080p amoled).

After asking around on Reddit, it looks like Xiaomi is using two different screen suppliers, with two different technologies.
The video below explains it perfectly well.

So it is possible to come across a "PenTile" (or diamond) screen, a classic for AMOLED, or else a "RGB Delta" screen.

The problem with the "RGB Delta" is that it is not as sharp as a "PenTile" because of its pixel layout. We can clearly see a drop in terms of definition and display sharpness. It is especially visible on the text (see photo below, Rgb Delta on the right)

I'm really disappointed with Xiaomi, either you get a good screen or a not so good one... I tried to contact the support to have more information, but without more.

thanks for the information! That is unfortunate. Maybe these screens are split along regions? The 780G 5G mi 11 lite comes in China and global versions (former network bands are slightly different in both 4g and 5g). Is yours a global, EU version or the China version? Device name MZB08JXEU 5G EU or M2101K9G 5G Global or M2101K9C 5G China? Am not 100% clear on whether the EU actually differs from the global.

My device name is M2101K9G (from French Xiaomi Store)

I have the same model, i don't use it right now, but soon. I'll give you my feedback soon
The thing with your A5 (2016) is that the pixel density is a bit higher. Also i remember my dad has this A5 (2016), and I was impressed with the quality of the screen

Hi, I can't see evidence of what display model has my mi 11 lite 5g.

I ordered in mi.com (Spain), special edition (MFF, Mi Fan Festival edition) 8G/128G black.

I compared with my wife mi 9T and mi 11 lite 5g looks equal or better, not worse.

Don't know if i have the good display or simply I can't appreciate it.

on my M2101K9G i have a rgb delta, the definition is different than my pixel, but on a daily usage, like 20cm from your eyes, is unnoticable, maybe I have bad eyes.
Anyways, I wll return my device, the speakers are awful, the camera is below average, and the screen is too big for me, I have a pixel 3a... I prefer compact phones.

@vanpopel, ok it's like me, RGB Delta (there is no "dot" like with PenTile).
So it seems to be very common, well here in Europe...

EDIT: And now I see that my screen is already burned.... (by 1h 1/2 of Waze use, 75% brightness)... wtf?

You can see it at the top and bottom (it's faint but clearly visible IRL)

@Xelycs

I am seeing some reviews on the web of different smartphones and they say pentile matrix resolution when screen is showing blue or red pixels is smaller than RGB, and image in RGB displays is sharper.

I haven't deep knowledge of screen technologies, and I suspect not only pentile or RGB information is enough to measure display quality. I mean, there may be good or bad RGB displays and good or bad pentile ones ¿?.

Is the RGB implementation of our screen so bad? Or it can be considered good display, and pentile excelent display? Or our RGB display is completely trash?

    Gizmochina previewed new Mi 11 Lite 5G NE. SD778 is slower (GPU) but offers better battery life what is weird considering 6 nm instead 5 nm. Everything is the same besides SoC. Everything including... display. Delta RGB is BACK. :D Just can't believe it. They clearly don't check XDA forum to find out about issues. Let's see if all phones will be RGB Delta or lottery again. :D

    It must be explanation for this. I think one is weight, second is how thin this phone is. I assume that Tianma might not be able to design display with different pixel arrangement to meet above due to manufacturing limits while Huaxing have technology but HDR is f**** and could be impossible to fix that for other technical reasons. Hence two types of displays as no manufacturer could design for them exactly what they wanted at least in such price range. Not an expert but maybe how thin AMOLED is also affects its final quality.

    I'm still surprised they fit to that phone stereo speakers (loud!) and decent 4250 mAh battery. If Xiaomi launched NE version due to 5 nm shortage chipsets, Mi Lite 5G must be a success and as for now no competitor designed such light phone with large display. Coming back to 200 g brick would be really hard.

    I'm reading and reading... Have Tianma displays on 2 Poco X3 Pro. No blur what so ever. Not too bright as my old Nokia 8 screen, still very descent. Can someone show me a picture of a "faulty" tianma display cause i can't imagine your ptoblems?

    Somebody put here screenshots Tianma Vs Huaxing side by side.

    It's not necessary true that all displays made by Tianma. I don't think they only make Delta RGB displays. It's not a manufacturer, it's a pixel arrangement what causes problem. You might have Tianma Pentile display and those are much better (of course still worse than 1080p LCDs but that's normal. 1080p LCD = 1440p OLED in terms of resolution).

    It's like with SoCs. 5 nm could be less efficient than 7 or 8 nm. Samsung does disappointing 5 nm so our SD 780G is far from perfect in terms of efficiency. SD778 6 nm offers around 15% better battery life but GPU performance is affected. This SoC is not made by Samsung.

    Ok,I can't take better pictures with Iphone 8.Tianma display is 30% brighter and colour calibration is different and more yellowish(in the reality they are not yellow as on those black and white theme dialer pictures but they are still slightly different).Both displays are crisp and clear and I'm sorry I don't have a better camera to take a picture of it.Here are the pics...

    GOT HUAXING! YES!

    FOURTH phone. Green Mint from Xiaomi UK. Difference is DAY AND NIGHT.

    I consider this display clearer than Redmi Note 8 Pro while Tianma is clearly the worst performer. What an absolute joke. I wasn't convinced that difference is there but after displays side by side showed by one user I knew I couldn't go wrong with this last gamble.

    Hi. I got Mi 11 Lite 5G from Vodafone in UK. Black colour. Display is absolute disaster. Clarity is like in cheap phone 7 years ago. Additionally this display uses 3.8 TIMES more mAh in auto brightness then IPS in my Redmi Note 8 Pro causing much faster battery drain. It was in 90 Hz but now I'm testing in 60 Hz and it will be approximately around double what RM8 Pro needs for display.

    This is absolute joke Xiaomi. They sent reviewers good phones and scamming customers with cheap junk displays.

    For that reason I can't see any other choice than return this phone. I was so excited because of lightweightness and there we go... I feel Xiaomi scammed me. This is nowhere premium or midrange display. This is cheapest of the cheapest AMOLED. RN8 Pro IPS feels like Lamborghini compared to that junk. Mi Lite 5G screen is so unclear it causes huge discomfort for my eyes.

    Thanks for this thread.

    Just received my phone, ran the ADB command and found it's DisplayDxe: K9 42 02 0b amoled dsc cmd!! (Huaxing) :)
    Purchased it (the black color) on eBay from this USA seller page: https://www.ebay.com/itm/194143992052
