Actuation Force of Touch Screen
Korean H Company, based in Korea, is a manufacturer of touch screens used for mobile, navigation and portable media player applications.
The company wanted to know the actuation force of the touch screen, used in a navigation device, to ensure proper manufacture and a consistent high quality end product for their customers. Their main priority was to establish that the screen required a uniform level of pressure to activate controls.
Mecmesin supplied a MultiTest 1-i computer-controlled test system, combined with an intelligent loadcell (ILC), an adjustable X-Y table and compression probes.
A decisive factor in the company‘s decision to buy the system was the software‘s ‘event‘ input facility, enabling signals from external devices to be incorporated into EmperorTM. In this case, the touch screen is monitored to register when a switch is activated during the compression test, thereby providing reliable information regarding the actuation forces involved.
