Samsung patents display method that lights up screen rows across columns

Patent drawing
Patent drawing from the official filing.

This filing describes a display setup where the screen is divided into small sections called dimming blocks. Instead of controlling each column separately, the system uses drivers to light up all the blocks in a single row at the same time, even if those blocks are in different columns.

Why it mattersThis approach could help manage the power and brightness of large screens more efficiently by simplifying how the display hardware is controlled.

In the filing’s own words

A display apparatus includes a substrate; a plurality of dimming blocks arranged in a plurality of rows and a plurality of columns on the substrate, each of the plurality of dimming blocks including a plurality of light-emitting devices; a plurality of driving devices configured to drive at least two of the plurality of dimming blocks, each of the plurality of driving devices being configured to drive at least two dimming blocks arranged in different columns; memory storing instructions; and at least one processor configured to control the plurality of driving devices. The instructions, when executed by the at least one processor individually or collectively, cause the at least one processor to control the plurality of driving devices to drive the plurality of dimming blocks arranged in a single row simultaneously.

What exactly they claim (claim 1)

1. A display apparatus comprising: a substrate; a plurality of dimming blocks arranged in a plurality of rows and a plurality of columns on the substrate, each of the plurality of dimming blocks comprising a plurality of light-emitting devices; a plurality of driving devices configured to drive at least two of the plurality of dimming blocks, wherein each of the plurality of driving devices is configured to drive at least two dimming blocks arranged in different columns; memory storing instructions; and at least one processor configured to control the plurality of driving devices, wherein the instructions, when executed by the at least one processor individually or collectively, cause the at least one processor to control the plurality of driving devices to drive the plurality of dimming blocks arranged in a single row simultaneously.
