Abstract

The invention provides a display device and a current protection method therefor. The device comprises a drive chip, an integrated control circuit, and a current protection circuit located between the drive chip and the integrated control circuit. The current protection circuit is used for controlling a drive control signal outputted by the drive chip to be outputted to a grounding end through a second drive control signal output end and a third drive control signal input end when a current generated by a voltage signal outputted by the integrated control circuit is greater than or equal to a threshold current, so as to enable the integrated control circuit to reset, and to stop the voltage signal, thereby preventing the voltage signal outputted by the integrated control circuit from generating an excessively large current so as to protect the drive chip and the signal lines of the display panel from being burnt up.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, and more specifically, to a display device and a current protection method thereof. Background technique [0002] Existing display devices include a display panel, a driver chip IC, and an integrated control circuit P, wherein the integrated control circuit P can control the normal display of the display panel after being connected to the display panel and powered on; the driver chip IC passes COG (Chip OnGlass, The chip is directly bound on the glass) and the process is bound on the display panel, which realizes the electrical connection between the display panel and the driver chip IC, so that the display panel can be driven by the driver chip IC for image display. In addition, the integrated control circuit P is also bound to the display panel through the COG process, so as to realize the electrical connection between the integrated control circuit P, the display panel and the d...
