摘要： An assembly for holding and controlling curvature of a glass plate for an optical touch sensitive system is described. The assembly comprising a first frame element extending in a first plane and configured to extend at least partially around a panel; at least one second frame element extending in a second plane and forming a support portion for the plate, and at least one spacing element positioned at least partially between the support portion and the first frame element. The spacing element us configured to control a curvature of the first frame element and wherein the at least one second frame element is configured to engage the plate at the support portion, is attached to the first frame element, and is tiltable, by controlling the curvature of the first frame element with said spacing element, to control a curvature of the plate.

摘要： A touch sensing apparatus is disclosed comprising a panel that defines a touch surface, a plurality of light emitters and detectors arranged along a perimeter of the panel. The light emitters are arranged to emit a respective beam of emitted light that travels above the touch surface, wherein the light detectors are arranged to receive detection light from the emitted light. The plurality of light emitters and detectors are arranged above the touch surface and are connected to a substrate extending in a direction parallel with a normal axis of a plane in which the panel extends. A method of assembling a touch sensing apparatus is also disclosed.

摘要： A touch sensing apparatus is disclosed, comprising a light transmissive panel that defines a touch surface, an opposite rear surface, and panel sides extending between the touch surface and rear surface. The panel sides define a perimeter of the light transmissive panel. The touch sensing apparatus comprises a plurality of light emitters and detectors arranged along the perimeter and adjacent the panel sides, a light guide arranged along the perimeter and having a first reflective surface comprising a diffusive light scattering element. The light emitters are arranged to emit a respective beam of light onto the diffusive light scattering element so as to generate propagating light that diffusively propagates above the touch surface, wherein the light detectors are arranged to receive detection light generated as said propagating light impinges on the diffusive light scattering element, and wherein the diffusive light scattering element is arranged at least partly outside the panel sides and extending at least partly above the touch surface.
