In review: Lenovo ThinkPad T490 with IGZO Low Power FHD screen

[Redaktion]

Notebookcheck is reviewing the Lenovo ThinkPad T490 at the moment. Our review sample contains a FHD screen that Lenovo markets as "Low Power". As we found out, the screen used here is not a normal a-SI IPS LCD, but a higher quality IGZO IPS panel.

Thank you for reviewing this panel! Since it is the same one found in the upcoming T495 and since the T490 has only a 50 mW/h battery, I think it will be a very popular option.

This was a helpful primer on IGZO:

Hopefully this will translate to 10+ real world hours on these new Thinkpads.

IGZO didn't save Sharp, but how did IGZO fall into the hands of BOE?

AFAIK, it's owned by another Japanese company. Sharp and LG (?) licensed for Apple production. How it got from there to China, I don't know.

With only 50Whr of battery, chances are slim. It may just pip 10 hours in the WiFi test, but the downside of smaller batteries still remains: it all lasts a long time until some system process or devices (or OS...) decides to drain 25Whr out of the blue. On a 74Whr battery, ~>1/3 of the battery is gone, the world isn't over. On a 50Whr battery, 1/2 of the battery is gone.

The point is, I'm still wondering why we couldn't get both in a Thinkpad? Of course, the Dell Latitude 7400 has both, but I'd rather not get a Dell Latitude again.

...Indeed! It says that the patent belongs to Japan Science and Technology Agency! Sharp was the one to first achieve mass production.

I'm interested in ordering one low-power 400nit fhd panel that's present on T490(s) to upgrade my T480.
Would you please check if either of these two panels you guys found on T490(s), AUO B140HAN05.7 and BOE NE140FHM-N61, is compatible with T480, to be specific a T480 with fhd panel of which eDP connector is also a 30-pin?
