Each of the light source(s) is disposed within the top plate in a recess for that light source, wherein the recess has refracting input face(s) such that light from a light source is coupled into the body of the top plate through the refracting input face(s).

Abstract: A packaged light emitting diode comprises a light emitting diode die and a cylindrical lens. The cylindrical lens is provided directly over a light emitting surface of the light emitting diode die. The cylindrical lens is advantageously provided as a truncated substantially oblate ellipsoidal lens in a body having two first truncations and one second truncation. As an alternative, the cylindrical lens is provided as an aspherical lens in a modified ellipsoidal body having again two first truncations and one second truncation. Light emitted through the lens has a narrow angular distribution along a first axis and a broad angular distribution along a second axis, orthogonal to the first axis. A touch sensitive apparatus comprising one or more such packaged light emitting diodes, being integrated within a top light-guiding plate of said apparatus, is also described.

Abstract: A touch sensitive screen arrangement includes an optically dispersive base plate and structures for transmitting light onto the base plate in response to an external body touching the screen at a touch point such that the location of incident light on the surface of the base plate is representative of the relative position of the touch point on the screen. The base plate captures and disperses light that is incident on it. The decrease in incident light intensity with distance from the location of incidence on the base plate approximates a substantially exponential function. A sensor detects intensity of light at a respective edge of the base plate. The arrangement calculates the relative position of the touch point on the screen from the detected light intensity and the exponential function and generates a control signal representative of a control input derived from the position of the touch point.
