Samsung patents display tech that saves battery in always-on mode

Samsung has filed a patent for a display system that manages power more efficiently during 'always-on' modes, such as when a screen shows the time or notifications. The invention uses a processor to cut power to internal components like the display driver while keeping the screen itself lit.

Why it mattersThis could help phones and other devices last longer between charges by using less energy when the screen is only showing basic information.

In the filing’s own words

A display device includes a display panel, a display driver electrically connected to the display panel, a panel processor that transmits a driving signal to the display driver, and a power supply that supplies power to the display panel, the display driver, and the panel processor. The panel processor controls the power supply to maintain power supplied to the display panel and reduce power supplied to at least one of the display driver or the panel processor in an always on display (AOD) mode.

What exactly they claim (claim 1)

1. A display device, comprising: a display panel; a display driver electrically connected to the display panel; a panel processor configured to transmit a driving signal to the display driver; and a power supply configured to supply power to the display panel, the display driver, and the panel processor, wherein the panel processor is configured to control the power supply to maintain power supplied to the display panel and reduce power supplied to at least one of the display driver or the panel processor in an always on display (AOD) mode.
