    摘要: 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 pa 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.

    摘要: A charge pump driver circuit has a first charge switch that couples a first node of a flying capacitor to a first power supply node, and a second charge switch that couples a second node of the capacitor to a second power supply node. Control circuitry is coupled to open the second charge switch and discharge the second node of the capacitor, in response to a control signal. Other embodiments are also described and claimed.
