Samsung patents screen that narrows viewing angle for privacy

1. An electronic device comprising: at least one processor including processing circuitry; memory including one or more storage mediums storing instructions; and a display, the display including: first light emission groups each including a first light emission region; second light emission groups alternatively disposed with the first light emission groups, the second light emission groups each including a second light emission region; first pixel definition portion surrounding the first light emission region; second pixel definition portion surrounding the second light emission region; first opaque portion disposed above the first pixel definition portions to define a first opening, the first opening allowing light from the first light emission region to be observable at a narrower viewing angle than a viewing angle at which light from the second light emission region is observed; and second opaque portion disposed between the first pixel definition portion and the first opaque portion to define a second opening, wherein the first opening and the second opening are substantially center-aligned with each other, wherein a first width of the first opening is substantially equal to or narrower than a second width of the second opening, and wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to: based on a state of the electronic device being in a normal display mode, control the first light emission groups and the second light emission groups to display a screen; and based on a state of the electronic device being changed from the normal display mode to a privacy display mode, control the first light emission groups to narrow a viewing angle of the screen displayed via the display.
