  • Patent number: 7719486
    Abstract: A voice circuit is arranged on a chassis member. The voice circuit comprises a voice output amplifier and a high-frequency bypass unit. An output terminal of the voice output amplifier is connected to one end of a voice coil in a speaker through an interconnection, and is grounded through a high-frequency bypass unit. The voice output amplifier supplies a voice current to the voice coil through an interconnection. The resonance frequency of the high-frequency bypass unit is set to the same frequency as that of a discharge current flowing in the chassis member. A high-frequency induced current generated in the voice circuit due to the discharge current flowing in the chassis member flows to a ground terminal through the high-frequency bypass unit.

  • Patent number: 7714832
    Abstract: A display screen is capable of having regions having different switching speeds as well as regions that are not switched. One region having a first switching speed may be for colour mode display and the other region having a second switching speed different from the first may be for monochrome mode display. Other regions may be off and not switched. In alternative versions, three or more switched regions may be established on a display screen. For example, a monochrome region may be nested inside a colour region, in which the colour region may be nested between off regions.

  • Patent number: 7714803
    Abstract: This invention describes procedures for writing data to a spatial light modulator (SLM) to achieve the purpose of “sub-frame method”, i.e. increasing effective frame rate of the SLM, without the need of additional color switching means or modulation at illumination source. The purpose is to improve the resolution of V3D displays based on projectors. The method divides the pixels of the SLM into a number of groups and defines each group as a sub-panel. Frames of image data are then written in sequence to each of the sub-panels in a fixed order. An image frame written to a sub-panel is called a “sub-frame” when displayed on the sub-panel. The method then displays one sub-frame on one sub-panel at a time, with the rest sub-panels displaying blank (black). If the SLM has no memory buffer and image is displayed when it is written, then all data on the SLM must be erased after a sub-panel is being displayed and before the next sub-panel is written.

    Abstract: A single clock driven shift register comprising multiple stages is provided. The (M)th stage comprises a latch unit, a logic unit, and a non-overlap buffer. The latch unit latches an input signal from the (M?1)th stage according to a clock signal. The logic unit connecting to an output terminal of the latch unit deals with an output signal of the latch unit and the clock signal with an NAND logic calculation. The non-overlap buffer connecting to the output terminal of the logic unit comprises at least three inverters connected in a serial, and an output signal of the first inverter coupled to the output terminal of the logic unit is input to an latch unit of the (M+1)th stage. Meanwhile, an output signal of the non-overlap buffer of the (M?1)th stage is input to the non-overlap buffer or the logic unit to delay the output signal of the non-overlap buffer.
