  • Patent number: 8666204
    Abstract: An optical transmission module includes a semiconductor substrate, a first film layer, an electronic component layer and a waveguide structure. The electronic component layer is used for converting a first electrical signal into an optical signal. The waveguide structure is formed on the first film layer, and includes a first reflective surface, a waveguide body and a second reflective surface. After the optical signal is transmitted through the semiconductor substrate and the first film layer and enters the waveguide structure, the optical signal is reflected by the first reflective surface, transmitted within the waveguide body and reflected by the second reflective surface. After the optical signal reflected by the second reflective surface is transmitted through the first film layer and the semiconductor substrate and received by the electronic component layer, the optical signal is converted into a second electrical signal by the electronic component layer.

  • Patent number: 8644654
    Abstract: The optical coupler module for converting and transmitting electrical/optical signals includes a semiconductor substrate, a first film, a second film, an electrical transmission unit, at least one signal conversion unit and an optical waveguide structure. The first film and the second film are formed on opposite surfaces of the semiconductor substrate.

The optical signal generated from the signal conversion unit sequentially passes the first film, the semiconductor substrate and the second film and enters the optical waveguide structure. Then, the optical signal is reflected by the reflector and transmitted in the waveguide body to be outputted. Alternatively, the optical signal is transmitted in a reverse direction from the optical waveguide structure to the signal conversion unit.

  • Patent number: 8174754
    Abstract: An electrophoretic display includes a plurality of pixels. A display method applied to the electrophoretic display includes the following steps. Firstly, a first frame is displayed on the pixels at a first time. Next, a difference amount between the pixels at the first time and the pixels at a second time predetermined for displaying a second frame is calculated. The second time is later than the first time. Next, whether the difference amount is larger than a predetermined value is determined. Next, corresponding part of the second frame is displayed on part of the pixels corresponding to the difference amount at the second time if the difference amount is not larger than the predetermined value.
