SOURCE DRIVER INTEGRATED CIRCUIT IN WHICH THE HIGH-VOLTAGE POWER GROUND AND THE LOW-VOLTAGE POWER GROUND ARE SEPARATED

摘要

The present invention relates to a technique for separating the grounds of a source driver integrated circuit in a liquid crystal display device, and more particularly, to a source driver integrated circuit in which the high-voltage power ground and the low-voltage power ground are separated from each other in a liquid crystal display device having a chip-on-glass (COG) cascade structure.
