Infrared light-emitting diode and touch screen
This invention discloses an infrared light-emitting diode. The infrared light-emitting diode comprises: only one core for emitting infrared light; a packaging body which at least comprises a first surface that is convex and in front of the core and a second surface that is plane and on one side of the core; and leads connected to the core and extending to outside of the packaging body; wherein the infrared light emitted by the core forms at least two beams of infrared light in different directions after being emitted from the packaging body through the first surface and the second surface. With such infrared LED and the touch screen, touch system and interactive display based on the LED, at least two beams of infrared light in different directions can be emitted requiring only one core.
