Drive chip and display apparatus

摘要

This drive chip has a configuration that is provided with: a base main body; two terminal groups that are respectively disposed along the base main body sides in the longitudinal direction of the base main body, said sides facing each other; a narrow-pitch section in one terminal group wherein terminals are disposed in a zigzag manner in two or more rows, said narrow-pitch section having a narrow terminal pitch in the longitudinal direction; a rough pitch section in the one terminal group, said rough pitch section having a terminal pitch in the longitudinal direction wider than that of the narrow pitch section; and a dummy bump that is disposed between the two terminal groups, said dummy bump being disposed parallel to the rough pitch section.

主权项

1. A drive chip comprising:
a base body; two groups of terminals that are arranged respectively along opposite sides of the base body in a lengthwise direction thereof; a narrow-pitch portion in which, with respect to one of the two groups whose terminals are arranged in two or more rows in a staggered formation, terminals are arranged at a narrow lengthwise-direction pitch; a rough-pitch portion in which, with respect to said one group of terminals, terminals are arranged at a broader lengthwise-direction pitch than in the narrow-pitch portion; and a bump that is provided between the two groups of terminals, in the rough-pitch portion.
