Display device, driver chip, and displaying method

A driver chip, comprising:

• a driver circuit to detect whether there is abnormal transmission between the driver circuit and a processor circuit in a display device;
• and
• a first pin, wherein the driver circuit is to output a control signal to a shift register circuit in the display device through the first pin,
• wherein when there is the abnormal transmission in a first display period of a first frame, the control signal comprises a disable level in the first display period to control the shift register circuit not to operate,
• wherein the driver circuit comprises:
• a gate controller coupled to the shift register circuit to output the control signal to the shift register circuit through the first pin;
• and
• a timing controller coupled to the gate controller to control the gate controller.

A displaying method, comprising:

• detecting, by a driver circuit, whether there is abnormal transmission between a processor circuit and the driver circuit;
• controlling, by a timing controller of the driver circuit, a gate controller of the driver circuit;
• and
• when there is the abnormal transmission in a first display period of a first frame, outputting, by the gate controller of the driver circuit, a control signal to a shift register circuit, wherein the control signal comprises a disable level in the first display period to control the shift register circuit not to operate in order to stop updating an image on a display array.
