Intel is showing a new concept laptop design called the Ambient at Computex Taipei 2019. The new laptop has a flexible OLED panel integrated into the touchpad, that is visible when the laptop is closed.
The idea is that you can see information and control some basic functions (like Spotify music) even when the laptop is closed. The touchbar is controlled by its own Atom CPU which means it does not draw much power. This is just a prototype at this stage, it'll be interesting to see whether any laptop maker will adopt this design in future devices.
