Abstract
A display device includes a display panel and an ion generator for generating positive ions and negative ions. The display device kills microorganisms or decomposes and removes harmful organic substances (e.g., sources of odor or environmental hormones), which exist either on the screen or in the air surrounding the display device, by utilizing the action of the positive and negative ions.
Claims27
A display device comprising:
- a display panel;
- and
- an ion generator for generating positive ions and negative ions,
- the positive ions include H+(H2O)m (where m is an arbitrary natural number), the negative ions include O2−(H2O)n (where n is also an arbitrary natural number), and the positive and negative ions react with each other to produce H2O2 or an OH radical.

A display device comprising:
- a display panel;
- and
- an ion generator for generating positive ions and negative ions, the positive and negative ions are supplied onto a screen of the display panel.
A display device comprising:
- a display panel;
- and
- an ion generator for generating positive ions and negative ions further comprising an environment analyzer for performing a quantitative analysis on the atmosphere,
