20130093732 | METHOD FOR DETECTING A TOUCH-AND-HOLD TOUCH EVENT AND CORRESPONDING DEVICE - Methods for determining a touch-and-hold touch event on a touch sensitive interaction surface of a touch sensing device are provided and comprise the steps of: a) determining a touch location of the touch event based on vibrations, such as bending waves, propagating through the interaction surface and b) determining whether the touch event comprises a hold touch event based on a sensed airborne signal. A device configured to carry out such methods is also provided. | 04-18-2013 |
20140035881 | TOUCH SENSITIVE DISPLAY WITH ACOUSTIC ISOLATION - Provided is a touch sensitive display, for integration into an electronic device configured to function in a predetermined temperature range, comprising a display panel and an acoustic isolating means. The acoustic isolating means is configured and arranged such that it presents a damping ratio of 5% or less with a variation of this damping ratio of 2 percentage points or less in the predetermined temperature range. Also provided is a touch sensitive display comprising a display panel and an acoustic isolating means. The acoustic isolating means comprises an elastic material in a first region on the front side of the display panel, with the front main side of the display panel being the displaying side, and an elastic material in a second region on the back side of the display panel and a compression controlling means for compressing the first and/or second region by a predetermined amount. | 02-06-2014 |
