Driver circuit for detecting panel status

Abstract

This invention provides a driving circuit for detecting panel status, comprising: a display module; a first driving module electrically connected to the display module; a first comparator electrically connected to both the first driving module and the display module; and an arithmetic module electrically connected to the first comparator. The first driving module charges the display module from a first voltage to a second voltage. The first comparator detects the detected voltage of the display module and compares it with the first voltage and the second voltage, then outputs a comparison result. The first comparator transmits the comparison result to the arithmetic module. The arithmetic module generates an arithmetic result based on the comparison result, an open-circuit signal, and a short-circuit signal. The arithmetic result corresponds to the circuit status of the display module, thereby determining whether an electrical defect exists.
