Abstract
An MOS integrated circuit chip for both addressing and driving display devices in display panels. The chip includes low-level logic devices for receiving and manipulating data for energizing a selected number of devices in the display panel. An output driver portion is coupled to the display devices and energizes the devices in response to the data received by the input logic. The output driver portion includes a transistor in which the drain region extends deeper into the substrate than the source region of the transistor, as well as the remainder of the active regions in the integrated circuit chip. Accordingly, the integrated circuit chip can withstand a high breakdown voltage at its driver output, while also providing high density logic devices thereby minimizing discrete components and their associated separate electrical interconnections.
