Abstract
An LED switch device and a matrix thereof are disclosed. There is an electroluminescent semiconductor element with a first polarity contact and a second polarity contact. There is also a first polarity LED lead frame, to which the electroluminescent semiconductor element is mounted. The first polarity contact of the electroluminescent semiconductor element is electrically connected to the first polarity LED lead frame. The LED switch device has a second polarity LED lead frame electrically connected to the second polarity contact of the electroluminescent semiconductor element. The LED switch device also has a touch sensor lead frame that is electrically connected to a touch sensor lead.
Claims20
A combination light emitting diode and electrical switch device, comprising:
- at least one electroluminescent semiconductor element with a first electrode connectible to ground and a second electrode connectible to a light emitting diode driver circuit;
- a touch sensor detecting a capacitance change at a single electrode from a touch input and connectible to an input port of a touch input controller;
- and
- a case encapsulating the electroluminescent semiconductor element and at least a portion of the touch sensor, light emitted from the at least one electroluminescent semiconductor element being at least partially unobstructed by the touch sensor.
A control switch, comprising:
- a light emitting diode driver integrated circuit with one or more output lines;
- a touch input controller integrated circuit with one or more input lines;
- and
- a multi-segment light emitting diode switch device, each segment including at least one electroluminescent semiconductor element with a light driver electrode connected to one of the output lines and a touch sensor detecting a capacitance change on a single electrode from a touch input and connected to one of the input lines, the electroluminescent semiconductor element and at least a portion of the touch sensor being encapsulated within a case and located in respective positions thereof;
- wherein the touch input controller is receptive to a continuous sequence of touch inputs to the touch sensor over a predetermined time interval.
