Abstract
According to an aspect, a display device includes: a display panel including a display surface; a sensor configured to detect an external object in proximity to or in contact with the display surface; an ultraviolet light emitter configured to emit ultraviolet light to the display surface; and a controller configured to control an operation of the ultraviolet light emitter. The controller increases an emission amount of ultraviolet light from the ultraviolet light emitter as the object approaches the display surface, and reduces the emission amount of ultraviolet light from the ultraviolet light emitter as the object recedes from the display surface.

A display device comprising:
- a display panel including a display surface;
- a sensor configured to detect an external object in proximity to or in contact with the display surface;
- an ultraviolet light emitter configured to emit ultraviolet light to the display surface;
- and
- a controller configured to control an operation of the ultraviolet light emitter, wherein
- the controller gradually increases an emission amount of ultraviolet light from the ultraviolet light emitter with respect to the distance between the object and the display surface as the object approaches the display surface, and gradually reduces the emission amount of ultraviolet light from the ultraviolet light emitter with respect to the distance between the object and the display surface as the object recedes from the display surface.
A sterilization device comprising:
- a sensor configured to detect proximity or contact of an external object;
- an ultraviolet light emitter configured to emit ultraviolet light;
- and
- a controller configured to control an operation of the ultraviolet light emitter, wherein
- the controller gradually increases an emission amount of ultraviolet light from the ultraviolet light emitter with respect to the distance between the object and the display surface as the object approaches the sensor, and gradually reduces the emission amount of ultraviolet light from the ultraviolet light emitter with respect to the distance between the object and the display surface as the object recedes from the sensor.
A display device comprising:
- a display panel including a display surface;
- a sensor configured to detect an external object in proximity to or in contact with the di splay surface;
- an ultraviolet light emitter configured to emit ultraviolet light to the display surface;
- and
- a controller configured to control an operation of the ultraviolet light emitter, wherein
- the controller increases an emission amount of ultraviolet light from the ultraviolet light emitter as the object approaches the display surface, and reduces the emission amount of ultraviolet light from the ultraviolet light emitter as the object recedes from the display surface,
- wherein a rate of decrease in the emission amount of ultraviolet light with respect to the distance between the object and the display surface as the object recedes from the display surface is smaller than a rate of increase in the emission amount of ultraviolet light with respect to the distance between the object and the display surface as the object approaches the display surface.
A sterilization device comprising:
- a sensor configured to detect proximity or contact of an external object;
- an ultraviolet light emitter configured to emit ultraviolet light;
- and
- a controller configured to control an operation of the ultraviolet light emitter, wherein
- the controller increases an emission amount of ultraviolet light from the ultraviolet light emitter as the object approaches the sensor, and reduces the emission amount of ultraviolet light from the ultraviolet light emitter as the object recedes from the sensor,
- wherein a rate of decrease in the emission amount of ultraviolet light with respect to the distance between the object and the display surface as the object recedes from the display surface is smaller than a rate of increase in the emission amount of ultraviolet light with respect to the distance between the object and the display surface as the object approaches the display surface.
