Samsung patents foldable phone display that speeds up when opening
This patent describes a foldable device where the screen runs at a lower speed when folded to save power. When you unfold the phone, the processor temporarily increases the screen's refresh rate to make the transition smoother before settling back to the lower speed.
In the filing’s own words
An electronic device is provided. The electronic device includes a first housing, a second housing movable and superimposed with respect to the first housing, a display of which a first area is exposed to the outside, wherein the display has a second area extended from the first area, upon switching from a first state to a second state, the second area is drawn out from inside the first housing and is exposed to the outside, and upon switching from the second state to the first state, the second area is inserted into the first housing, and a processor coupled to the display and configured to control the display such that the first area operates at a first scan rate in the first state, upon switching from the first state to the second state, the display operates at a second scan rate higher than the first scan rate.
What exactly they claim (claim 1)
1. An electronic device comprising: a first housing; a second housing movable and at least partially superimposed with respect to the first housing; a display of which at least a first area is exposed to outside of the electronic device through a front face of the electronic device, wherein the display has a second area extended from the first area of the display such that, when the electronic device switches from a first state to a second state, the second area is drawn out from inside the first housing and is exposed to the outside of the electronic device together with the first area, and when the electronic device switches from the second state to the first state, the second area is inserted into the first housing; one or more processors; and memory storing one or more computer programs including computer-executable instructions that, when executed by the one or more processors, cause the electronic device to: display dynamic content at the first area of the display and control the display such that the first area of the display operates at a first scan rate in the first state, while the electronic device switches from the first state to the second state, display the dynamic content at the first area and at least a portion of the second area and control the display such that the display operates at a second scan rate higher than the first scan rate at the first area and the at least the portion of the second area, and control the display such that, in response to completion of the switching to the second state, the display operates at the first scan rate with respect to the first area and the second area.
