Integrated driving apparatus for display apparatus
View Patent ↗An integrated driving apparatus having an elongated shape mounted at a peripheral portion of a display apparatus comprising a display section on a panel substrate comprises a logic section, a power supply circuit section, and a D/A converter. The logic section comprises a digital display data processor and a timing signal generator which generates a timing control signal necessary for the display apparatus and the D/A converter converts digital display data obtained by the digital display data processor into analog data. The power supply circuit section generates a power supply voltage used in the display apparatus using a signal from the timing signal generator. The power supply circuit section and the D/A converter are provided on left and right of the logic section with the logic section therebetween so that the power supply circuit section and the D/A converter are placed adjacent to the logic section along a long side direction of the elongated shape of the integrated driving apparatus.
1. An integrated driving apparatus for a display apparatus having a display section in which a plurality of pixels are arranged in a matrix form on a panel substrate, the integrated driving apparatus comprising:
a logic section which comprises a digital display data processor which processes digital display data and a timing signal generator which generates a timing control signal necessary for the display apparatus based on a timing signal from outside, and having a logic circuit element;
a digital-to-analog converter which converts digital display data obtained by the digital display data processor into analog data; and
a power supply circuit section which generates a power supply voltage used in the display apparatus using a signal from the timing signal generator, wherein
the integrated driving apparatus has an elongated shape extending along a row direction or a column direction of the display section so that the integrated driving apparatus can be mounted on a peripheral portion of the display section on the panel substrate; and
the power supply circuit section and the digital-to-analog converter are provided on left and right of the logic section with the logic section therebetween so that the power supply circuit section and the digital-to-analog converter are placed adjacent to the logic section along a long side direction of the elongated shape.
