  • Patent number: 11443667
    Abstract: The disclosure provides a display apparatus and a data driving integrated circuit thereof for removing the interference patterns caused by radio wave interference. In the disclosure, a data driving integrated circuit includes a gamma voltage generating circuit, power terminals for receiving power voltages of the gamma voltage generating circuit. The data driving integrated circuit couples dummy terminals to the power terminals, so as to decrease the equivalent impedance of the power terminals through a parallel connection between the I/O ESD protection circuits. Therefore, the DC offset of the power voltages caused by the radio wave interference may be decreased.

  • Patent number: 9875700
    Abstract: A source driver utilized for a display device and switching between two operational modes includes a reception module for receiving a plurality of display information and a plurality of transmission channels. Each transmission channel includes a register module for receiving one of the plurality of display information; a voltage level transformer for determining a voltage level of the one of display information; a polarization digital-to-analog converter for processing a digital-to-analog operation for the voltage level of the one display information; and an output module for outputting a plurality of voltage levels of the display information. The voltage levels of every two adjacent transmission channels include different polarization of voltage levels, and the output module processes an odd-number switching operation before outputting the plurality of voltage levels.

  • Publication number: 20140043065
    Abstract: A driver architecture includes multiple drivers connected in series. An (i)th driver includes a reading circuit, a configuration circuit, a clock generator and a data input/output start pulse (DIO) generation circuit. The reading circuit reads an (i)th DIO outputted from an (i?1)th driver according to multiple reading pulses. The (i)th DIO includes an (i?1)th configuration of an (i?1)th driver and an (i)th trigger pulse. The (i)th trigger pulse is for activating the (i)th driver. The configuration circuit configures an (i)th configuration of the (i)th driver. The clock generator generates an (i+1)th trigger pulse for activating an (i+1)th driver. The DIO generation circuit outputs an (i+1)th DIO to the (i+1)th driver. The (i+1)th DIO includes the (i)th configuration and the (i+1)th trigger pulse.
