Abstract

A method, system, and computer program product for determining a level of cleanliness of a multi-touch screen display, characterizing objects that make contact with the screen, and initiating a specific maintenance action on the screen, based on screen cleanliness and the object(s) characterization(s). A screen diagnostic and maintenance (SDM) utility initiates a number of procedures to determine the type of object(s) and a set of characteristics of object(s) that make contact with the touch screen. Based on the results of the procedures, the SDM utility characterizes/identifies the object(s). In addition, the SDM utility initiates maintenance screen check(s) based on information stored in maintenance configuration file(s). Based on the results of the maintenance check(s), configuration file(s) data and type and characterization of the object(s) that have made contact with the screen, the SDM utility determines the type of maintenance that is performed and the timing/schedule of the maintenance action(s).

(7) an application of a transparent film to the screen surface; and

(8) a utilization of a wiper mechanism that dispenses cleaning material across the screen surface.

7. The device of claim 6, said SDM utility further providing the functions of:

displaying a list of maintenance tasks to be completed by a user to execute a maintenance action;

enabling execution of the maintenance action via the displayed list, wherein a user is able to interact with said list to indicate a completion of one or more tasks on the list;

providing a maintenance action via an external screen protection device, wherein said screen protection device has a blue-tooth capability, which enables communication between the protection device and the electronic device in order to provide an appropriate set of details of the affected area of the screen to the protection device; and
