Display system and display device

A display system applied to a display device comprising a plurality of display partitions, comprising:

• a multi-scenario trigger circuit, configured to determine, according to a usage scenario in which the display device is triggered, a display partition for high-definition display among the plurality of display partitions;
• a display content generation circuit, configured to render each frame of a partition image of the display partition for high-definition display, and fuse a partition identifier of the display partition for high-definition display into each frame of the rendered partition image to form a corresponding frame image data stream;
• a display drive control circuit, configured to generate a control instruction stream to drive the display partition for high-definition display so that the display partition for high-definition display displays each frame of an image in the frame image data stream;
• wherein, each control instruction in the control instruction stream carries a same time identifier as the corresponding rendered partition image;
• a drive circuit, configured, for the frame image data stream and the control instruction stream which have a same partition identifier, to form control instructions which have a same time identifier, and rendered partition images into a group, and in chronological order, drive, group by group and according to a control instruction in a current group, the corresponding display partition to display the rendered partition image in the current group;
• wherein all chips in the display device are connected in parallel with a same signal bus which is used to transmit data or instructions;
• different chips time-multiplex the signal bus;
• a separate signal line is provided in the display system applied to the display device for transmitting an enable signal, which is a pulse signal;
• the chips connected with the signal bus are configured to cache received control instructions simultaneously upon receipt of the enable signal.
