Abstract

The invention provides a driving circuit, a display device and a detection method by using a time schedule controller. The driving circuit comprises: N pairs of chip pins, wherein each pair of chip pins comprises an input pin and an output pin, after the driving circuit is bound with a display panel through a COF, each pair of chip pins form a path through a pair of connected panel pins on the display panel, and N is a positive integer larger than or equal to 1; a detection circuit which comprises a detection signal generator which is connected with an input pin of at least one pair of chip pins in the N pairs of chip pins and is used for loading a detection signal to the input pin connected with the detection signal generator; and an output node which is directly connected with the outputpin of at least one pair of chip pins in the N pairs of chip pins or indirectly connected with the output pin of at least one pair of chip pins through the detection circuit. The binding condition ofthe display panel can be rapidly and accurately detected.

Description

technical field [0001] The invention relates to the field of electronic circuits, in particular to a driving circuit, a display device and a detection method using a timing controller. Background technique [0002] Chip On Film (COF) is a grain soft film that fixes the chip (IC) on the flexible circuit board (FPC). This packaging technology is used in many displays such as LCD, OLED, etc. chip. This kind of chip is mostly used as the source driver (Source Driver) and gate driver (Gate Driver) of the display driver. In the driving circuit, one end of the COF is connected to the chip, which is responsible for receiving the signal transmitted by the chip, and the other end of the COF is connected to the display panel (Panel), which is used to transmit the signal output by the IC to the Panel, and drive the display panel for display. [0003] The chip is bound to the display panel (Panel) through COF. If the binding is abnormal, it will cause various display failures of the di...
