Abstract

The invention discloses a display driving circuit, a driving method of the display driving circuit, and a display device. A power source detection circuit is additionally arranged in the conventional display driving circuit, and determines whether a voltage reference signal, outputted by a power source management circuit, is abnormal or not according to a standard voltage reference signal outputted by a logic circuit; the power source management circuit is controlled to stop outputting the voltage reference signal when the condition that the voltage reference signal is abnormal is determined, so that the power source management circuit is in a static mode, at the moment, a display panel is in a normally white mode or a normally black mode, the possible condition that a gate drive control signal, mismatched with a voltage required by a shifting register, is inputted in the shifting register of the display panel is eliminated, and the phenomenon that an assembled display product is abnormal, which is caused by the fact that a signal outputted by the display driving circuit is mismatched with the display panel, is avoided.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display driving circuit, a driving method thereof and a display device. Background technique [0002] In recent years, with the vigorous development of semiconductor technology, portable electronic products and flat panel display products are also emerging. A flat-panel display is generally composed of a matrix of pixels arranged in both horizontal and vertical directions. When the flat-panel display is displayed, a gate input signal is generated through a shift register, and each row of pixels is scanned sequentially from the first row to the last row. When designing a flat panel display, it is necessary to design an appropriate shift register to ensure its stable operation. Usually, the shift register is composed of multiple stages of shift register units connected in series, and the output signal of the shift register unit of the previous stage is used as the input signal ...
