P50-B UHD 3840x2160 Screen Panel Model Number

Has anybody taken one of the 3840x2160 P50-Bs apart and noted down the exact model number of the screen?

Also, is the screen a true and proper 3840x2160 RGB or is it a useless cheating pentile RGBW piece of crap like on the Lenovo Y50? I got one of those Lenovos and I am deeply disappointed in the screen - any single pixel wide line in a colour other than black or white looks like it was printed on a dot matrix printer with every other pixel missing, which makes small font rendering unusable with any kind of color coding. So if the Toshiba happens to have a proper full pixel count 3840x2160 screen in it, I would very much like to know the part number for it so I can look into retrofitting it into my Lenovo.

 

I know this post is a bit old, but I found it in a Google search, so I suspect that responding to it will not only help you, but also anybody else who may find this post via Google.

I have the Toshiba P50t-B, and the display is true 3840x2160, not pentile. Each pixel is capable of independently producing the full range of colors that the display can produce.

EDIT: Also the model is the Sharp LQ156D1JX01. It says so in the screen resolution dialog.

EDIT2: Also you might hear some things about the IGZO displays, despite not being pentile (i.e. having all RGB components per pixel), having white subpixels in addition to RGB (in a square arrangement. Well I placed a water drop on my screen for magnification and can confirm that it is a 100% standard RGB matrix, no white subpixels and no resolution cheating.
