On August 22, Patently Apple posted a report titled "At the IMID-24 Conference, Samsung announced that they’re working to reduce Power Consumer of mobile devices by 50% for the AI Era." Lee Cheong, Vice President of Small and Medium Business Division at Samsung Display, said in a keynote speech at the IMID opening ceremony held in Jeju on the 21st, that "We are developing technology to eliminate all factors affecting power consumption or replace them with other technologies in order to lower pane included in all displays, and have improved power consumption by more than 30%." He added that we're also "developing various form factor products, such as double-foldables, multi-foldables and rollables."

That same day a Samsung patent was published in Europe titled "Electronic Device including Rollable Display."

Samsung's patent covers a method is provided for improving touch usability of a display by detecting the sensitivity of the touch panel associated with the bending or lifting of the display in an expanded state and correcting the sensitivity.

A rollable electronic device is provided that is improved in touch usability of a display by detecting the sensitivity of the touch panel associated with the bending or lifting of the display in an expanded state and correcting the sensitivity.

According to an aspect of the invention, a method is provided for compensating for changed touch sensitivity of a touch panel of an electronic device. It is detected whether a rollable display of the electronic device is expanded. It is detected whether the touch sensitivity of the touch panel of the rollable display is changed, in case that the rollable display is expanded.

A rolling direction and a length of extension of the rollable display is changed, in case that the touch sensitivity is changed. It is detected whether a resistance of an expansion area of the rollable display is changed. The touch sensitivity of the touch panel is compensated for, in case that the resistance is changed.

According to an aspect of the disclosure, a rollable display including a touch panel is provided. The rollable display includes a first insulting layer, and an electrode layer disposed on the first insulating layer and including a first electrode and a second electrode configured in a form of a metal mesh. The rollable display also includes a second insulating layer disposed under the first insulating layer, and at least one strain gauge sensor disposed in a dummy section of the first insulating layer. The rollable display further includes a first bridge for connection of the electrode layer, disposed on the second insulating layer, and a second bridge for connection of the at least one strain gauge sensor, disposed on the second insulating layer. The electrode layer is connected to the first bride using a first via. The at least one strain gauge sensor is connected to the second bridge using a second via.

A method and a rollable electronic device are provided for effectively detecting a change in touch sensitivity due to bending and lifting of a display.

 Samsung's patent  FIGS. 5A and 5B below are diagrams illustrating the electronic device in a state in which the flexible display area is contracted; FIGS. 6A and 6B are diagrams illustrating the electronic device in a state in which the flexible display area is expanded.

Samsung's patent FIG. 4 above is a diagram illustrating an exploded perspective view of a flexible display mounting structure of an electronic device that is expanded; FIG. 7 is a flowchart illustrating a method of detecting and compensating for a change in touch sensitivity of an electronic device.

The patent figures appears to cover both a smartphone and a tablet. Below is the CEO of Samsung Display presenting a demo of a tablet with a rollable/scrollable display that expands the display to 17".
