Dell's latest innovation focuses on better repairability and sustainability. Concept Luna showcases a laptop that can be fully disassembled in only 30 seconds using a simple push-pin tool. It signifies a new hope for the industry to produce laptops that are easy to maintain and have a longer lifespan.

Microsoft has been playing safe when it comes to hardware. The boldest product that the company recently launched could be the Surface Duo which is a dual-screen device. However, this patent filed by the company earlier has shown that it still has an adventurous spirit for putting out innovative products.

This year, we have seen smartphone manufacturers proposed some ideas on how to make their own under-display camera. As we've heard, the feature is a challenging one to put on smartphones considering photo quality and some other technical problems. That's why we have to wait this long for it to become a mainstream feature in the smartphone market. Now, Samsung has been spotted with an idea as well as it involves a sub-display to hide the camera.

Smartphone manufacturers always show their innovative or sometimes crazy design ideas through the patents that they've submitted. This time, LetsGoDigital has dug up something interesting that comes from Samsung. It looks like the Korean tech giant has a plan to manufacture a sliding phone that is also equipped with two screens.
