Abstract
The present disclosure is directed to systems and methods for determining sheet resistance values in a liquid crystal display (LCD) panel. In certain embodiments, a system for determining sheet resistance values in an LCD panel may include a display driver integrated circuit (IC). The display driver IC may include a first switch coupled to a first input/output (I/O) pad and a second I/O pad such that the first I/O pad is configured to couple to a voltage source and the second I/O pad is configured to couple to a current source. The display driver IC may also include a second switch coupled to a third I/O pad and the second I/O pad such that the second switch has substantially the same geometry as the first switch and the third I/O pad is configured to couple to a thin-film transistor (TFT) layer of the display panel.
