Abstract:
1. A driver circuit for reducing IC malfunction, the driver circuit comprising: a source driver IC, a gate driver IC, and a wire on array, wherein the source driver IC and the gate driver IC connect through the wire on array and the source driver IC provides a driver signal to the gate driver IC through the wire on array; the driver circuit further comprising a negative feedback module electrically connected with the wire on array to be configured to keep the wire on array voltage constant; wherein an input terminal of the negative feedback module electrically connects with the wire on array near to the gate driver IC, and the input terminal receives a signal of the gate driver IC from the wire on array to be configured to an input signal of the negative feedback module; an output terminal of the negative feedback module electrically connected with the wire on array near to the source driver IC to be configured to send an output signal of the negative feedback module to the wire on array; the negative feedback module including a comparing unit, an amplifier unit, and a feedback unit electrically connected with each other; wherein the comparing unit receives the input signal of the negative feedback module to be configured to compare the input signal and a feedback signal of the feedback unit to generate a differential signal and then amplifier unit amplifies the differential signal to output to the wire on array.
