Samsung patents display that turns on screen sections one by one to save battery

Patent drawing
Patent drawing from the official filing.

Samsung has been granted a patent for a display device that manages power by turning on different sections of the screen at slightly different times. When the battery is low, the device uses this staggered startup method during screen changes to reduce the immediate power spike required to light up the entire panel at once.

Why it mattersThis technique could help extend the usable time of devices like tablets or monitors when the battery is running low, offering a subtle but effective way to conserve energy during critical moments.

In the filing’s own words

A display device may include: a display panel including a plurality of display blocks; a battery configured to supply electric energy to the display panel; a plurality of driver integrated circuits (ICs) respectively connected to the plurality of display blocks; at least one processor including processing circuitry; and a memory storing instructions and including at least one storage medium, wherein, when individually or collectively executed by the at least one processor, the instructions cause the display device to: identify a state of charge of the battery; identify a remaining charge of the battery as being in a first range based on the state of the charge; and based on a screen transition event of the display panel and the remaining charge of the battery being in the first range, control the plurality of driver ICs to turn on the plurality of display blocks at different times in a first order.

What exactly they claim (claim 1)

1. A display device comprising: a display panel comprising a plurality of display blocks; a battery configured to supply electric energy to the display panel; a plurality of driver integrated circuits (ICs) connected to the plurality of display blocks; at least one processor comprising processing circuitry; and memory storing instructions and comprising at least one storage medium, wherein the instructions, when executed by the at least one processor individually or collectively, cause the display device to: identify a state of charge of the battery; identify a remaining charge of the battery as being in a first range based on the state of the charge; and based on a screen transition event of the display panel and the remaining charge of the battery being in the first range, control the plurality of driver ICs to turn on the plurality of display blocks at different times in a first order.
