  • Patent number: 10790414
    Abstract: A light emitting diode includes an N-type semiconductor layer, a P-type semiconductor layer, and a light emitting layer. The P-type semiconductor layer is located on the N-type semiconductor layer. The light emitting layer is located between the N-type semiconductor layer and the P-type semiconductor layer. The N-type semiconductor layer has a first region and a second region connected to each other. The first region is overlapped with the light emitting layer and the P-type semiconductor layer in a first direction. The second region is not overlapped with the light emitting layer and the P-type semiconductor layer in the first direction. A sheet resistance of the P-type semiconductor layer is smaller than a sheet resistance of the N-type semiconductor layer.

  • Patent number: 10036928
    Abstract: A liquid crystal display (LCD) panel includes a first substrate, electrode patterns, a second substrate, and a liquid crystal (LC) layer. The electrode patterns are located on the first substrate, and a lateral electric field is generated via the electrode patterns according to a driving voltage. The second substrate is located opposite to the first substrate. The LC layer is located between the first and second substrates and includes a voltage driven LC layer and an induced LC layer. The voltage driven LC layer is located on the electrode patterns and is driven by the driving voltage to be optically anisotropic or optically isotropic. The induced LC layer is located between the voltage driven LC layer and the second substrate and induced to be optically anisotropic when the voltage driven LC layer is driven to be optically anisotropic. A thickness of the LC layer is larger than 4 ?m.
