Abstract
An apparatus includes a display screen including a first array of first light-emitting diodes for emitting visible light and a second array of second light-emitting diodes for emitting ultraviolet light, wherein the second light-emitting diodes are interspersed among the first light-emitting diodes. A method includes a computing device receiving input from a remote server indicating that a surface of the computing device should be disinfected, the computing device detecting that a display screen is in a closed positioning facing the surface, wherein the display screen includes an array of light-emitting diodes for emitting ultraviolet light, and controlling operation of the light-emitting diodes to disinfect the surface in response to the input received. The surface may, for example, be selected from a keyboard, a touchpad, and a cover.
