ABSTRACT:
A touchscreen system is provided that incorporates a simplified sealing system around the bezel. The touchscreen system includes a planar touchscreen coupled to a display device having a planar display surface, the touchscreen having a touch sensitive region on a touchscreen surface. A frame is positioned above the touchscreen. The frame includes a central opening that substantially provides an outer border for the touch sensitive region, a rigid portion comprising an outer periphery of the frame, a flexible resilient portion connected to the rigid portion, the flexible portion comprising an inner periphery of the frame, and a sealing portion interposed between the touchscreen surface and the flexible portion. The flexible portion of the frame is directed out of a plane defined by the rigid portion toward the touchscreen prior to bringing the frame into contact with the touchscreen. Upon installation into the touchscreen, the flexible portion is displaced such that flexible portion exerts pressure on the touchscreen through the sealing portion. The simplified sealing system around the bezel can be used with any type of display having a planar display surface or any type of touchscreen technology.
