  • Patent number: 9960766
    Abstract: The present disclosure provides an IGBT driving circuit, including an optocoupler chip and a power amplification circuit. The optocoupler chip includes an isolation amplification unit and a fault protection unit, and the fault protection unit includes a desaturation module and a fault feedback module. The desaturation module is configured to transmit a warning signal to the fault feedback module when detecting that a potential of a collector of the IGBT is overhigh or the potential of the collector of the IGBT changes overfast. The fault feedback module is configured to transmit a fault control signal to the external controller after receiving the warning signal so as to control the external driving signal outputted by the external controller and enable the isolation amplification unit to output an IGBT driving signal for controlling a shutdown of the IGBT.

  • Patent number: 9946085
    Abstract: An embodiment of the present invention provides a 3D panel. The 3D panel includes a first substrate, a second substrate, and liquid crystals configured to be filled between the first substrate and the second substrate, wherein both the first substrate and the second substrate are provided with a common electrode and a signal electrode. Since the substrates at two sides of the 3D panel of the present invention have electrodes which can be independently controlled, the switching of a grating electrode function between the upper and lower substrates can be achieved by switching the signal to the two substrates, thereby improving the application range of the 3D panel and the compatibility and versatility of the 3D panel. In addition, the embodiments of the present invention also disclose a method for producing the 3D panel and a 3D display apparatus having the 3D panel.

    Abstract: A light guide plate (LGP) and a method for fabricating the same are disclosed, the LGP is electro-conductive. The fabrication method including the following steps: preparing an electro-conductive solution; making one or more surfaces of a regular LGP adsorb the electro-conductive solution uniformly; drying the LGP which adsorbs the electro-conductive solution to form an electro-conductive film on the one or more surfaces. A method for fabricating the LGP is also disclosed in which electro-conductive organic macromolecular compound is used as a raw material. The effect of static charge on the LGP is avoided by the electro-conductive property of the LGP.
