Abstract: A bandgap reference circuit generates a PTAT voltage and a CTAT voltage having a different temperature characteristic from the PTAT voltage and generates a reference voltage based on the PTAT voltage, the CTAT voltage, and a compensation voltage. The bandgap reference circuit generates a CTAT current having a different temperature characteristic from the PTAT voltage based on the CTAT voltage and determines the compensation voltage based on the CTAT current.

Abstract: Provided are a source driver configured to drive a data line of a display panel and a liquid crystal display (LCD) device including the same. The source drive configured to compare whether data of consecutive gate lines in the display panel and data of adjacent data lines in the display panel are identical or not, and selectively disable output amplifiers connected to the data line having identical data.
