<P>PROBLEM TO BE SOLVED: To provide a data driver for a panel display device that enables a uniformity inspection of dynamic characteristics between outputs and the like to be carried out even in a structure where correction resistors for correcting resistance differences between lead wires are provided in the data driver. <P>SOLUTION: A data driver for a panel display device comprises: a plurality of driver output terminals connecting to a plurality of data lines of a display panel, and a plurality of output circuits each outputting output signals from the plurality of driver output terminals. Each of the plurality of output circuits comprises: an output buffer that outputs the output signal; a first resistor one end of which connects to one driver output terminal; a first switch and a second resistor connecting between the output node of the output buffer and the other end of the first resistor in series; and a second switch connecting between the output node of the output buffer and the other end of the first resistor in parallel with the first switch and the second resistor. <P>COPYRIGHT: (C)2013,JPO&INPIT |
