Patent ID: 7932886

Claim:
An active matrix substrate, comprising: a plurality of scan lines; a plurality of data lines; a plurality of transistors corresponding to an intersection of the plurality of scan lines and the plurality of data lines; a plurality of analog video signal lines providing a plurality of first analog video signals; a plurality of digital video signal lines providing a plurality of digital video signals; a first data line driving circuit that is electrically connected to a plurality of first ends of the plurality of data lines and that drives a part of the plurality of the data lines simultaneously, the first data line driving circuit having a first physical circuit structure that includes a first shift register and a plurality of switches, the plurality of switches electrically connecting the plurality of analog video signal lines to output a part of the plurality of first analog video signals to the part of the plurality of data lines simultaneously by a plurality of first output signals from the first shift register; and a second data line driving circuit that is electrically connected to a plurality of second ends of the plurality of data lines and that drives all of the plurality of the data lines simultaneously, the second data line driving circuit having a second physical circuit structure that is different from the first physical circuit structure of the first data line driving circuit and that includes a second shift register, a plurality of circuits, and a D/A converter, the plurality of circuits electrically connecting the plurality of digital video signal lines to output the plurality of digital video signals to the D/A converter, the D/A converter converting the plurality of digital video signals into a plurality of second analog video signals and output the second analog video signals to all of the plurality of data lines simultaneously.
