Samsung patents display tech that fades privacy filters at the edges

Samsung has been granted a patent for an electronic device that can adjust the viewing angle of specific parts of its screen. The system applies a privacy filter to a central area while gradually reducing the effect on the surrounding pixels to create a smooth transition.

Why it mattersThis could make privacy screens look less jarring by blending the restricted view into the normal display rather than using a hard line.

In the filing’s own words

An electronic device is provided. The electronic device includes a display panel configured to adjust a viewing angle of at least a portion of an image displayed on the display panel, display driver circuitry, memory, including one or more storage media, storing instructions, and at least one processor, including processing circuitry, communicatively coupled to the display driver circuitry.

What exactly they claim (claim 1)

1. An electronic device comprising: a display panel configured to adjust a viewing angle of at least a portion of an image displayed via a display area of the display panel; and display driver circuitry, wherein the display driver circuitry is configured to: when a filter for user privacy is applied to a first area of the display area: perform a first pixel-processing to apply the filter to the first area, wherein the first pixel-processing is performed for controlling a viewing angle, and perform a second pixel-processing to apply the filter to a second area of the display area surrounding the first area, wherein the second pixel-processing is performed for controlling a viewing angle, and wherein an intensity of the filter applied to the second area by the second pixel-processing spatially decreases as a distance from the first area increases.
