Abstract:
A semiconductor device for supplying a first group of drive signals to a first group of signal electrodes and a second group of drive signals to a second group of signal electrodes of an image display apparatus that displays a two-dimensional image, the semiconductor device comprising:a first group of output terminals that are arranged in a first region along a first edge in a longitudinal direction of the semiconductor device, and that are adapted to output a specified number of drive signals among the first group of drive signals to the image display apparatus; a second group of output terminals that are arranged in a second region along the first edge and adjacent to the first region, and that are adapted to output the second group of drive signals to the image display apparatus; a third group of output terminals that are arranged in a third region along the first edge and adjacent to the second region, and that are adapted to output the remaining drive signals among the first group of drive signals to the image display apparatus; a first bi-directional register that is adapted to supply the first group of drive signals, which are successively input, to the first group of output terminals, respectively, in an order determined by a control signal; a second bi-directional register that is cascade-connected to the first bi-directional register and that is adapted to supply the first group of drive signals, which are successively input, to the third group of output terminals, respectively, in an order determined by a control signal; a first group of dummy terminals arranged corresponding to the first group of output terminals along a second edge in the longitudinal direction of the semiconductor device; and a second group of dummy terminals arranged corresponding to the third group of output terminals along the second edge.
