BillI have fair knowledge that Sony and Samsung actually co-owns the
factories that manufacture the TFT panels that both use for thei computer
displays and televisions. When these two launch their respective products in
the market, the key differentiating point will be in the software as well as
the logic controls (processors, chipsets etc) they use to drive the panel
and the images it outputs.
So, yes, in this day and age, there's a lot of joint-manufacturing as a
means to cut development as much as assembly costs but the final
differentiator will still be there. This is similar to how Sony licenses the
use of its sensors to Nikon but the resulting image control and output
quality are different.

Apart from Sony-Samsung, there is also IBM-Lenovo-Toshiba who shares
identical manufacturing of their TFT panels for the ThinkPads and Toshiba's
Satellite etc products.

I'm sure there are other partnerships too.
