P1 Gen 2 - Small dots on OLED screen

2019-10-07, 20:46 PM

Hi everyone,

 

I got my P1 Gen 2 a couple of days ago. After configuring everything, I noticed that there are very small dots all over the screen. These seem to be part of the capacitive sensor for touch detection, but I am not sure.

 

The problem with the dots is that they add texture to all images. Clear colors become grayish. Also, the texture creates Moire patterns.

 

Is this normal? Does anybody else experience this issue? I tried to take a picture, but the dots are very small and they are not captured by the camera.

 

I requested a panel change to support, but if the new panel has the same issues this may be a no-go for OLED.

Thanks

Hmm... I have a 4K UHD multitouch display on my P1 Gen1 and I do not see any dots (this is not an OLED panel, however). My X1YogaGen2 with OLED display and multitouch looks clear and I do not see any dots. That said, my P53 is arriving soon with the 4K OLED Multitouch display so I'll be on the lookout for what you've described. Have you talked to technical support to determine if the panel is correct with the dots? Please report back if you could.

They don't know anything about it. They said that 'it may be normal', but they delivered another panel for replacement.

 

I also tested the screen test of the bios, and the dots are still there.

 

The best description I have for the problem is that you are looking at a piece of very fine fabric. The dots are barely perceptible, but overall they generate the patterns described above.

So, you haven't yet installed the replacement panel. correct? The touchscreen technology incorporates a transparent grid under the top glass layer. It should not, IMO, alter the color rendition of the panel elements. My P1Gen1 UHD multitouch LCD panel does not exhibit perceptible dots, but I know that the grid must be there. I have always found the OLED panels to be sharper than the corresponding UHD 4k panels as the latter seem to always come with a matte screen which, itself, introduces some light scatter distortion. I'll report back on my P53 when it arrives later this week with the OLED multitouch panel. I believe that the panel in the P53 is the same as for the P1Gen2.

I haven't installed the replacement panel yet. I am waiting for it to arrive. I'll update the thread after installing the new panel.

 

Thanks for the quick reply.

I'm just setting up my P53 with the OLED display panel. I can confirm that if I look really hard and almost have my face into the display, I can see very faint dots/grid on an overall white screen. With anything else it is extremely hard to see them. I agree that it is part of the touch panel, but it's not annoying at all. If you don't want a touch panel, then you have the option of selecting at 4K UHD display without the multitouch capability.The grid is a part of the WACOM touch application in conjunction with the Active Pen. The pointing accuracy of the pen is quite good, better than the previous implementation that I used in the past.

 

UPDATE: I really can only see the dots/grid when the display is a maximum brightness. Turning the display brightness down 1 or two notches makes the dots/grid almost disappear at least to my eyes. Again, I can only see them on a continuous white background. I cannot distinguish them on any color or grayscale.

Re: P1 Gen 2 - Small dots on OLED screen

Hi everyone,

 

I have the same issue than fclad on my P1 Gen 2: a very thin diagonal grid covers all the screen and gives a fabric-like texture.

It is especially visible over light colors background. It's really annoying, any application with a white/light grey background looks horrible.

 

Lenovo sent a technician to change the screen but the new one has the same issue.

 

When looking very closely, I can see that the pattern is visible even when the screen is turned off, and it indeed seems to come from the touch layer, not the actual OLED panel underneath.

 

Has your new screen the same issue fclad?

 

I would like to change to a non-touch screen but the only available options in France are IPS FHD panels (400 or 500 nits) but I need a higher resolution than FHD (at least QHD). There is a non-touch IPS UHD option available on the US website though.

GM!

 

I agree that the lines/dots are the artifacts of the touch screen grid. If you also look very closely at the top of the panel, you can see a couple of rows of the grid. These are visible even when the panel is turned off so it is a part of the touch layer. Interestingly, I looked at my P1Gen1 4K UHD IPS screen and I can see the SAME artifacts on the top of the panel (also visible when the panel is off). So, there is no defect in either panel, but the lines are the limitation of the touch screen technology. If I look very closely at the P1 panel, I can also see additional lines/dots in a white screen, but the subpixel pattern on that panel does not create the same interference artifacts that I can see on my P53 OLED panel. Sigh!

Re: P1 Gen 2 - Small dots on OLED screen

Sorry I didn't bother to get a better image, but the subpixel array makes it look like there are holes in it.  The blues are arranged in pairs with gaps.  I guess maybe it's just a perfectly aligned touch screen thing but I don't really think so.  I really wanted the 500 nit IPS display with the touchscreen...  but the touchscreen is more of a 'just in case I ever want it' sort of thing.  Anyways, the point of OLED is to have a really nice display so this is pretty bad.  For reference, I can see the dots within about an 18" range of the display.  They are present in Windows and in Linux with the display set at either 4k or 2k. Now to decide if I return it.  :[

I believe that the negative space between the blue pixels is what causing the visual effect even at a distance of 18". I have had touch screens in the past and I've never seen this type of artifact due to the overlays. However, other manufacturers are using the same Samsung OLED panel albeit w/o the touch overlay and I've not seen anything noted in any review that calls out these lines/dots. So, there must be an interaction with the touch panel as well that is exacerbating the artifacts. I've learned to live with it as the issue is most visible on 100% white backgrounds or within web-pages. The color gamut is awesome and the panel is quite bright as well.

yep I noticed it with mine imediatly it really effects the image quality.  My thinkpad yoga has a 3k touchscreen and built in pen and it looks fine.  Its a real shame from a distance watching movies look great but up close it is extremly frustrating and effects the fidelity of the image.

Agreed. I too have an X1YogaGen2 with the OLED panel. NO artifacts at all. Disappointing for certain.

Re: P1 Gen 2 - Small dots on OLED screen

i'm so stress out about this.. should I ask for refund because when i called they didnt told me it was a known defect..

 

they told me " you want a replacement or not..?? not no worries it's a known defect we will sent you a perfect one!

 

they said the same with my gamma problem in dark scene (gray shading) on my yoga gen2.. they sent it back from repair without repairing it and i was out of warranty afterward..

 

I don't understand why they can't understand what their customer want.. we want a perfect laptop oled screen with 0 issue!! right gamma even in dark gamma scale with no touch layer that create a haze over.. and no matte all .. certainly no small dot spanning all the screen.. 


who would have tought that somebody would do a matte oled..

 

wow adding any layers of possible haze over a should be perfect technology is really .....
and matte stuff is the worst because with time it become worst and worst the more you clean the screen.

if i get a refund now i'm stuck with 64gb of ram + 1000$ of ssd drive for nothing. cant believe this

I do not believe that what you are seeing is a defect. It does appear, however, to be an artifact of the combination of the digitizer and the OLED subpixel arrangement. The fact that more than a few people have noted this in the forum should be evidence that what you are seeing is not out the the ordinary for this P1 display. You have a choice to make; either live with the dots/lines and enjoy the wonderful color gamut and a multi-touch capability or return the unit and get a 4k UHD matte display panel instead with no multi-touch. An OLED replacement panel, unfortunately, will exhibit the same characteristics that you have called out. Personally, I've learned that if I'm using my P53 at a normal viewing distance, then the dots are almost invisible in my normal usage. However, if you are doing photo editing the effect on the texture might not be acceptable. Your choice.

Re: P1 Gen 2 - Small dots on OLED screen

2019-11-27, 20:57 PM

i didnt even boot windows with it.. i knew from the start all the DEFECT of that screen. it's not because everybody have that defect that it's not a defect.. it's actually a known defective product sold by lenovo and you encourage them to do so.

 

i had the yoga 2 oled on the side of it and i have oled phone..

 

I even tried washing the screen to see if it was dirty because of the colored haze..  

 

saying it's not a defect to have any type of artefact on an oled screen is crazy ... like small black dots.. what is the difference of this and having 10000 small half size dead pixels?

 

as crazy as saying it's normal not to have any shades of gray in dark scene (on the yoga 2) .. for the gamma bug i had to find a tool to confirm that it wasnt normal and it wasnt fixable either.. 

who cares that you can live with defective oled.. hahha as long as you stay at normal viewing distance.. you are kidding me.. are you a lenovo employe? i paid 3500$ for this ... i'm gonna get a refund and wait for gen 40 maybe after 40 iteration they can do something even bordeline decent.. personnaly if i was them i would block the sale and recall them all.. the one who made that screen everybody should be fired.. everybody.. 

we just want a perfect oled screen with no artefact and no layer over it just a perfectly clear glass... nobody care about touch on it certainly not if it destroy the screen.. it's not a phone.. it's a 3.500$ desktop replacement for work

This forum is user to user and not a Lenovo technical forum. My suggestions have already been made. Your recourse is to either  return the unit and select another option combination or request a refund.

Yeah, I think this is garbage on a top end display on a high end laptop.  Based on no actual knowledge it seems to me like a design defect as opposed to a manufacturing defect which seems like a useful thing to distinguish.  That said, I used it in the car with direct sun today and it was really impressive in that regard.

 

Anyways, no need to start accusing and insulting.

not accusing or insulting just stating the truth.. 

it's unnaceptable from companies like lenovo to steal money from people who don't know what oled screen are and might keep them without knowing they have duds.. and unnaceptable for any who protect them doing it.

 


they still ship them.. and it's freaky
