What Does Lay-On-Table Design Mean?

A lay-on-table design is a design where a smartphone, or a case or accessory, provides a lip or edge around the screen, so that if the device is placed face down, the screen does not actually contact the surface beneath it. Modern smartphones are being designed this way, in order to avoid scratches on the surface of the touchscreen.

Techopedia Explains Lay-On-Table Design

In many cases, the phone itself does not have a lay-on-table design, so users have to buy shells or cases that raise the face of the phone above the table surface. For example, some older iPhones are completely flat, and the lay-on-table design is provided by the case.
