Provided are a virtual optical input device and a method of controlling the same. In the method, a portion of an input means such as a finger, and a portion of a shadow of the input means generated by a light source are detected through image processing. Physical variations formed between them are used to detect the touch contact of the input means, calculate the position of the input means, and input the corresponding command. Accordingly, it is possible to provide various input patterns.

An air conditioner includes a cabinet positioned on an indoor ceiling. The air conditioner also includes a front panel that is coupled to the cabinet and has an air inlet. The air conditioner further includes a suction panel coupled to the front panel and configured to move to open or close the inlet. In addition, the air conditioner includes a sensor unit positioned on the suction panel, configured to detect a position of an indoor person, and configured to move downward with respect to the suction panel in response to an operation instruction.

A surface discharge type air cleaning device including an insulating dielectric body formed in the shape of a sheet, a discharge electrode formed at the upper surface of the insulating dielectric body, and a ground electrode formed at the lower surface of the insulating dielectric body. The discharge electrode is formed of a closed pattern having a predetermined area on the upper surface of the insulating dielectric body. The discharge electrode has a non-pattern part disposed in a pattern part where the pattern is formed. The electrode is not formed at the non-pattern part. The ground electrode is formed at a predetermined position corresponding to the non-pattern part. The area of the non-pattern part is reduced to decrease generation of ozone, and the area of the pattern part is enlarged to increase generation of negative ions and hydroxyl radicals. Consequently, the number of negative ions and hydroxyl radicals is increased while the amount of ozone is decreased, and therefore, air cleaning efficiency is improved.

A concept of improving a resolution by using human's visual characteristics is provided. Bu the present invention, an image can be displayed at a more improved resolution than an actual physical resolution, thereby obtaining the same effect that the resolution is physically improved. An image signal corresponding to one frame is split into a first image signal and a second image signal, and a first image and a second image are formed based on the first image signal and the second image signal. Then, the first image and the second image are respectively displayed at a first location and a second location. As a result, a viewer can view the image at an improved resolution.
