Patents by Inventor Chang-Ming Chiu

Chang-Ming Chiu has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11127669
    Abstract: A flexible display screen and a flexible device are provided by the present application. The flexible display screen includes a bending area. The bending area includes at least one wiring layer. The at least one wiring layer includes a plurality of conducting wires arranged at intervals. Each of the plurality of conducting wires includes at least two current paths. The at least two current paths are configured to transmit an identical current signal passing through corresponding conducting wire. Since each of the plurality of conducting wires has at least two current paths, the plurality of conducting wires can continue to provide an electrical current when the plurality of conducting wires are damaged during bending. Therefore, the flexible display screen has strong stability and long service life.

  • Patent number: 9773852
    Abstract: An organic electroluminescence display includes a plurality of scan lines, a plurality of data lines, at least one first pixel circuit, and at least one second pixel circuit. The scan lines and the data lines cross. Each of the first and second pixel circuits is electrically connected to one of the scan lines and one of the data lines. The first pixel circuit includes at least one first driving transistor having a first channel in a first channel direction. The second pixel circuit includes at least one second driving transistor having a second channel in a second channel direction. The second channel direction is different from that of the first channel direction.

  • Patent number: 8358261
    Abstract: A liquid crystal display (LCD) device is provided. The LCD device includes a LCD panel, which further includes a plurality of scan lines, a gate driving circuit, a clock circuit. The clock circuit includes a clock generator and an adjusting circuit. The clock generator generates a clock signal having a first high voltage level and a first low voltage level. The adjusting circuit, coupled to the clock generator, receives the clock signal and generates an adjusted clock signal having the same period as the clock signal. The adjusted clock signal has a second high voltage level and a second low voltage level. The gate driving circuit, coupled to the clock circuit, receives the adjusted clock signal as a gate driving signal in order to drive the scan lines.

  • Patent number: 7368956
    Abstract: A data slicer with a source-degeneration structure is described. In particular, this invention can be implemented in a FM demodulation system. It located at the end of the demodulator. The data slicer can slice a signal transmitted through air and demodulates the same with a demodulator to produce a frequency-shifted modulation (FSK) signal. The signal is a perfect square-wave and is transmitted to a base band circuit. The data slicer with a source-degeneration structure obtains the exact reference voltage. The reference voltage is not affected by noise and doesn't need the coupling capacitor, so it can reduce the difficulty of manufacture and cost. The present invention has a common-source unit with a source-degeneration resistor for producing an input signal and a reference voltage, and a comparator unit for comparing the input signal and the reference voltage and outputting a square-wave signal that corresponds to the input signal.
