    摘要: This invention relates to an improved design for the transmit and receive optical elements of a waveguide-based optical touch screen sensor, where at least one converging lens is incorporated within the body of each transmit and receive element. The optical elements of the improved design are more mechanically robust, easier to incorporate into the touch screen assembly, and are less susceptible to stray light and the ingress of foreign matter. In one embodiment the converging lens collimates the light into a plane wave. In another embodiment the converging lens focuses the light to an external point. In yet another embodiment, each transmit and receive element also includes at least one diverging lens. The transmit and receive elements and associated waveguides preferably comprise photo-patternable polymers.

    摘要: The invention provides a method for operation of a touch input device comprising a touch input area. The method comprises the steps of (i) detecting a touch or near-touch of an object on or near said touch input area; (ii) determining a parameter indicative of the size and/or shape of said object; (iii) comparing said parameter with at least one predetermined value; and (iv) enabling an operational state of said touch input device in response to said comparison. The parameter may be compared with one or more threshold values which delimit the operational state of the input device. Such operational states include a sleep mode or active mode, the use of a full QWERTY or reduced keyboard, translation or rotation of graphical elements, etc. The method is particularly suitable for differentiating between a touch by a stylus or touch by a finger.

    摘要: Planar lenses for integrated optics applications, in particular for use in optical touch screen sensors are disclosed. The disclosed planar lenses include a slab waveguide and an optical waveguide, preferably formed in unitary fashion, wherein the slab waveguide has a curved end face to focus light into or out of the optical waveguide, and wherein at least one additional lens is included within the slab waveguide. In one aspect of this disclosure, the additional lens is a diverging lens. In a second aspect the additional lens is a converging lens. The additional lens may match the acceptance angle of the optical waveguide to the curved end face of the slab waveguide. Alternatively, it may improve the tolerance of the planar lens to design or assembly errors and/or temperature variations. Preferably, the planar lenses are composed of a photo-patternable polymer, and the additional lenses are composed of air.
