(US6113708-A)   NOVELTY - Cleaning a component of a flat-panel display includes subjecting the component to a fluid whose absolute pressure exceeds the absolute pressure at the triple point and is at least 20% of that at the critical point of a mole-fraction dominant constituent.    USE - The invention is used for cleaning components of flat-panel cathode-ray tube displays.    ADVANTAGE - The invented cleaning technique is utilized to remove a substantial portion of the damaging organic residue, thus avoiding performance degradation. The cleaning fluid used has a quite higher solvency at elevated pressure compared to that at standard pressure, and lower viscosity and surface tension compared to that of the standard, which all in turn lead to rapid wetting of, and good penetration into the material that comes in contact with the fluid, thus providing excellent cleaning performance. The dominant component of the cleaning fluid is carbon dioxide which does not cause significant damage to the environment. The invention, as a whole, thus provides an efficient, environmentally safe way for cleaning components of a flat-panel display.
