RELATED APPLICATIONS 
     This application claims priority to Taiwan Application Serial Number 98216141, filed Sep. 1, 2009, which is herein incorporated by reference. 
     FIELD OF THE INVENTION 
     The present invention relates to a holding device, and more particularly to a two-in-one screen cleansing device that holds a cleansing fluid dispenser and a cleansing unit together as an integral body for cleansing a screen conveniently and efficiently. 
     BACKGROUND OF THE INVENTION 
     Generally, a display screen, such as a television screen, a computer screen or a monitor screen, after being used for a period of time, would have dust, particles, or other impurities attached thereto due to electrostatic attraction. Smudges and grease might also attach to the screen due to contact of the user&#39;s hand with the screen. The dust, particles, impurities, smudges and grease attached to the screen would have adverse influence on the clarity of screen and the viewing quality. 
     The dust, particles, smudges or grease on the screen must be cleansed. To do so, cleansing fluid is usually used to enable effective cleansing. 
     In a conventional way of cleansing the screen, cleansing fluid is dispensed onto a piece of cleansing cloth and the cleansing cloth is then used to wipe the screen surface, in order to remove the dust and other smudges from the screen. 
     In the past, the cleansing fluid and the cleansing cloth for cleansing screen are usually separately positioned at different places. The user has to troublesomely locate them one by one for use. There are times the user could find the cleansing fluid but not the cleansing cloth or vice versa. Moreover, with the conventional cleansing cloth, it is not easy for the user to apply adequate and uniform force to wipe the screen; and, due to the uneven surface of the user&#39;s hand, the cleansing cloth handled by the user&#39;s hand might not be able to fully and uniformly contact with the screen. Under these conditions, it is uneasy to thoroughly cleanse the screen. 
     Due to the above-mentioned causes, the conventional screen cleansing elements, that is, the cleansing cloth and the cleansing fluid, has relatively poor applicability.
