Abstract
A display device and a driving circuit are discussed. According to an embodiment of the present disclosure, it is possible to stably maintain the output signal of the driving circuit when the lock signal indicating the synchronization state of the clock signal is changed due to an operation error such as overcurrent in a display device using a point-to-point interface. In addition, according to an embodiment of the present disclosure, it is possible to prevent damage to the display panel due to an overload generated in the output signal of the driving circuit by an operation error. In addition, according to an embodiment of the present disclosure, it is possible to prevent overload of the driving circuit and damage to the display panel by controlling the operation of the driving circuit through a differential input voltage between the timing controller and the driving circuit.
