Abstract
The invention has a display device and a control method for generating anions, having a dust-proof net in front of an enclosure. A fan in the enclosure drives an air flow toward the dust-proof net facing the front of the display device. The anion generator is placed in the air flow to disperse anions through the dust-proof net. At least one speaker fixed by the side of the fan diffuses anions by its vibration wave. An anion sensor is placed on the dust-proof net to detect anion concentration for controlling anion quantity. Those positive ions and harmful particles around the user can be cleared instantly.
Claims10
A display device comprising:
- an enclosure having an inside, which a dust-proof net is disposed at the front surface;
- a fan fixed on the inside of the enclosure, which blows an air stream toward the dust-proof net;
- at least one speaker disposed at the side of the fan;
- and
- an anion generator disposed in the air stream to generate anions, wherein the anions disperse along the air stream.
A control method of a display device with an anion generator, comprising steps:
- (1) starting the display device;
- (2) starting the anion generator at the same;
- (3) detecting anion concentration to determine if the anion concentration is greater than a predetermined value;
- (4) if the anion concentration is greater than a predetermined value, stop the anion generator;
- and
- (5) if the anion concentration is not greater than a predetermined value, continue operating the anion generator.
