DISPLAY DRIVING CIRCUIT AND SEMICONDUCTOR DEVICE INCLUDING THE SAME

摘要

A display driving circuit includes a fault detector circuit which detects a fault in a circuit device and outputs a fault signal about the fault, a polarity selector circuit which stores polarity selection information and outputs a mode selection signal based on the polarity selection information, and a feedback circuit, wherein the feedback circuit includes an OR gate which receives an inverted signal of the mode selection signal and an inverted signal of the fault signal, an AND gate which receives the inverted signal of the mode selection signal and the fault signal, a first P-type transistor which is turned on or off by an output signal of the OR gate; and a first N-type transistor which is turned on or off by an output signal of the AND gate.

主权项

1. A display driving circuit comprising:
a fault detector circuit configured to detect a fault in a circuit device and generate a fault signal in response to the detection of the fault; a polarity selector circuit configured to store polarity selection information and generate a mode selection signal based on the polarity selection information; and a feedback circuit including,
an OR gate configured to receive both an inverted signal of the mode selection signal and an inverted signal of the fault signal;an AND gate configured to receive both the inverted signal of the mode selection signal and the fault signal;a first P-type transistor configured to selectively activate based on an output signal of the OR gate; anda first N-type transistor configured to selectively activate based on an output signal of the AND gate.
