  • Head-mounted eye tracking system
    Patent number: 11803052
    Abstract: A head-mounted eye tracking system including an optical combiner, an eye tracker and a signal processor is provided. The optical combiner includes an optical coupler. The eye tracker is at least partially disposed on the optical combiner and is suitable for sensing an eyeball movement of a wearer. The eye tracker includes a plurality of light-emitting devices and a plurality of sensing devices. The plurality of light-emitting devices are suitable for emitting tracking beams. The plurality of sensing devices are suitable for receiving the tracking beams reflected by the eyeball of the wearer. The signal processor is signally connected to the eye tracker.

  • Substrateless light emitting diode (LED) package for size shrinking and increased resolution of display device
    Patent number: 10134709
    Abstract: A light emitting diode package including a circuit layer, a light-shielding layer, a plurality of light emitting diodes and an encapsulation layer is provided. A thickness of the circuit layer is less than 100 ?m. The light-shielding layer is disposed on a first surface of the circuit layer and the light-shielding layer has a plurality of apertures. The light emitting diodes are disposed on the first surface of the circuit layer and in the apertures of the light-shielding layer. The light emitting diodes are electrically connected to the circuit layer. The encapsulation layer covers the light-shielding layer. A refractive index of the encapsulation layer is 1.4 and to 1.7. The Young's modulus of the encapsulation layer is larger than or equal to 1 GPa. A thickness of the encapsulation layer is greater than thicknesses of the light emitting diodes.
