190PPI triple laptop panel build for a PC monitor

post #1 of 5
Thread Starter 
I was looking into doing this a while back but never got around to it. I was thinking of taking three 11.6" panels at 1080p and making a custom bezel. This would result in a 19" monitor running at 3240x1920. The in between of each screen would be almost none existent compared to normal triple monitor builds due to the small size of the panel rim. Also the pixel density would be something we really only see in cell phones.

This thread recently went over something very similar:
http://www.overclock.net/t/1389756/custom-screen-31-3600x1600-cost-250

I was thinking of using one of the following panels.

https://www.laptopscreen.com/English/model/ASUS/TAICHI~21/
https://www.laptopscreen.com/English/model/Acer/ASPIRE~S7-191-6447/

These are the only monitors i could find that are IPS, 1080p, 11.6" and happen to all be touchscreen(not a requirement but could be a bonus if i can get it working biggrin.gif )
If anyone has any suggestions of other screens that fit the idea let me know

I was also going to use this controller board for connecting

I was planning on starting the project in a week or so and would like to here any advice you guys would like to offer.

Let me know what you guys think thumb.gif

I think that, in order to determinetthe true validity and market value of such a concept, it is quite imperative, nay, necessary, to send me the working prototypes, in order for them to be properly evaluated.

It's only right...

This IPS panel looks interesting LP125WH2(SL)(B3) It's only 1366x768 resolution but that means you can get it for a lot cheaper?
If you linked 3 of them together it would have the same dimensions as a 22" 16:9 monitor with 2304 x 1366 pixels.

However I dont think the project is worth doing as there is just too many negatives. First those cheap electronics boards don't look reliable, do they introduce input lag? Is the panel 6 bit or 8 bit, how does the lvds dithering work. With 3 seperate panels do you end up with 3 times the amount of backlight bleed from the edges. Those panels you mentioned can really be had for that price? Make sure you get an IPS and not some "compatible" version which will basically be a cheap TN.

You need the IPS technology if you are thinking of turning widescreen panel to use in portrait mode because TN panels have such poor vertical view angles. I tried turning my 22" TN panel sideways and looked at a flat colour, its horrible how much banding there was.

Also laptop screens are not as good as desktop monitors for brightness and contrast ratios. Desktops are typically 350 cd/m2 and 1000:1 where as laptops are 200 cd/m2 and 600:1

Overall it would be better to buy a proper e-ips monitor for desktops, with known response times, a guarantee incase it breaks, and best of all without 2 black bars running down the screen and lots of lose wires hanging around.

Most of these concerns are mute in the fact that the listed panels are an exact replacement of the panels that come in these ultrabook products. They are 8 bit panels, Backlight bleed is a warranty covered defect since they are A+ and factory direct, they are IPS(same as the original panels. I am also fully aware of IPS VS TN tech. The one good point you made was about the dithering in the controllers. While i know they do not have internal scalers in them and the input lag would be low i do not know about the dithering.

I have gone over the reviews regarding the ultrabooks and specifically in regards to the display quality and brightness has never been brought up as an issue(although after you mentioned the brightness i am now on a mission to find out the exact spec for it)

Your last point is not a factor since i already have a Qnix IPS panel running at 2560x1440@120hz. This project is for PPI bragging rights and just some fun engineering. Wires hanging around would be bad engineering something i don't plan on doing which is specified in the original post about the custom bezel. And it would not be better to get an e-ips panel as the project is related to PPI and this clearly would destroy any desktop monitor on the market in relation to PPI (therefor NOT better by the scope of work).

Thanks for all the input though you did make some good points thumb.gif

EDIT: I don't want to use a 720p panel since that would be a major hit on the PPI. Overall your comment was helpful but i think you missed the underlining point.

Well now i might wait till i can find this panel direct from manufacturer.
