    Default Inside the L702x FHD 3D 1080p Display Panel Assembly

    Since there are many questions being asked about the L702x FHD display, I thought I would share with you what makes this beautiful new Dell display tick. I will add more pictures as I edit them, but for now I submit the following for your review.

    I hope this helps you become more aware of the technology within the L702x.



    The panel itself is a LP173WF2 (TP)(A1) [see basic specs below], which performance wise in 2D is on par with the AU Optronics B173HW01 v.4. In other words, it is a very nice panel that is sharp and bright and offers above average viewing angles. I cannot test 3D performance yet as I am still waiting on the 3D glasses like many others.

    Although 1mm or so thicker, the physical panel will work as a direct fit for the Dell 1747/49 and L701x and looks to use the same standard 40pin connector. The LVDS cable looks similar as well to the other Dell 17" system cables, but this specific cable has the additional 3D/IR lead. If no 3D is used or needed, it looks like a standard L701x LVDS cable could be used for both 900p and 1080p use.

    The 8bit IR module at the base is interesting and in theory could support other IR functions in addition to the 3D glasses.

    More data/pics to follow-

    Regards,
    Scott

    Here is a view of what is behind the panel along with the part numbers of the casing and LVDS cable. Note the cable says 50-pin. This is the 3D display LVDS cable. To confirm, the panel uses a 50-pin connector.

    The pictures below show the 3D glasses IR module both with the bezel on and off. I can't wait to see if there are some other uses for this IR port in addition to the glasses. Hmmmmmm.....

    Awesome thread Scott did you have any sure news about the L702x's 900p screen swapping (with the AUO B17HW01 v4)?

    Interesting... it seems the LP173WF2 shows up as a LGD02C5 in the hardware string. Below, is the info as SIW sees it.

    Great info there, thanks Scott!

    On the other hand, if you want to upgrade your L701x with such panel and have the 3D, you'll have to change the front bezel too.

    Scott, first off, thanks for the thread and all. I have some comments/questions...

    That's quite an optimistic comparison Unfortunately I had no luck finding any datasheet for the LG panel, but one thing I know is that it has a color gamut of 72%, while the AUO panel (being B+RGLED or RGBLED, not sure) has 90%...

    Does that mean we only need the glasses and can skip the USB IR emitter? I have no idea, what Dell ships, but apparently these are sold as a kit or separately.

    Interesting indeed. Same with B156HW01 V.7 on the L502X showing as AUO17ED...

    And the GPU, right? I mean, how would you connect the 50-pin cable and/or take advantage of the 120Hz refresh rate?
