Description

Ink jet head cleaning method Technical Field The present invention relates to an inkjet head cleaning system and an inkjet head cleaning method, and more particularly, to an inkjet head cleaning system and an inkjet head cleaning method that improve cleaning efficiency. Background In recent years, with the development of technology, display products having more excellent performance while achieving miniaturization and weight reduction have been produced. Heretofore, among display devices, a conventional Cathode Ray Tube (CRT) television has many advantages in terms of performance and price, and is thus widely used, but in terms of miniaturization or portability, a display device (for example, a plasma display device, a liquid crystal display device, an organic light emitting display device, and the like) which overcomes the disadvantages of the CRT and has advantages of miniaturization, light weight, low power consumption, and the like has been attracting attention. In manufacturing the display device, an inkjet printing method having an effect of reducing costs or the like is used. In the inkjet printing method, cleaning of the inkjet head is necessary, and thus various apparatuses for cleaning the inkjet head have been developed.
