- the LSI 102 displays a scene design on the liquid crystal panel 7 by executing a main event based on an instruction from the CAN microcomputer 103 (step SI 1).
- the LSI 102 determines whether or not there is a sub-event execution instruction included in the control signal from the CAN microcomputer 103 (step S12). Here, if there is an instruction to execute a sub-event, it is determined whether or not the instructed sub-event is a sub-event included in the scene design currently displayed on the liquid crystal panel 7 (step S13).
- step S13 it is determined whether or not the SEN included in the control signal from the LSI 102 power CAN microcomputer 103 is the SEN included in the currently displayed scene design.
- LSI 102 determines that the SEN does not exist in scene design A and does not perform processing. In other words, only sub-events that exist in the currently displayed scene design A are not processed.
- the display information on the LCD panel 7 can be divided into main events and sub-events so that only the necessary display can be changed, reducing the layout change process. It can be made possible.
- the layout information can be compressed, the memory capacity of the display system can be reduced and the device can be downsized. It can be done.
- the memory capacity means the memory capacity in comparison with the memory capacity required when full screen rewriting is performed each time without partial screen rewriting. In other words, a small amount of memory means that it is less than the memory capacity required for full screen rewriting every time.
- the memory capacity when not using a sub-event is (number of main events + number of sub-events) X full screen memory capacity.
- the memory capacity is the number of main events X full screen memory.
- Capacity + number of subevents X Memory capacity for subevent images. In this case, if the memory capacity of the image to be rewritten by the sub-event is 20% of the total screen ratio, the memory capacity is reduced by the number of sub-events X (100%-20%).
- the multi-display real-time processing circuit 8 which is a display control means is provided with a screen layout table, and screen layout data is generated using this screen layout table, and each information is stored. The point that the processing load of the multi-display real-time processing circuit 8 is reduced by displaying the displayed images as a list was described.
- the instrument panel display image includes a still image and a moving image, and each is displayed at a display position determined by the screen layout.
- these image data are generated by being shared by each processor (the processor provided in the vehicle system 3, the vehicle system 4, and the safety system 5), and are displayed on the display platform unit via the in-vehicle LAN 31. Sent to 6.
- the display platform 6 side should have image data for the still image that constitutes the instrument panel display image. You could think so.
- the still image is a background image of the meter portion (the meter portion of the meter portion is a moving image), or
- a background image of the fuel system can be considered.
- the liquid crystal controller 11 in the display platform unit 6 includes the display data memory 15 and the display data memory 15 has a background.
- a background image storage unit 15a for storing data for displaying an image and a screen layout table 15b for generating screen layout data are included.
- the instrument panel display system 1 shown in FIG. 18 has a configuration in which a background image is stored on the display platform unit 6 side.
- image data for generating a still image is stored in the display data memory 15 described above, and a moving image is displayed.
- the image data for generating the image is also obtained by each processor.
- the instrument panel display system 1 uses the display platform section 6 to generate image data (background image data) for generating a still image used in the main event and sub-event for generating the instrument panel display image.
- image data background image data
- the background image data used in the main event and sub-event is stored in the display data memory 15, but only the background image data used in the main event is stored in the display data memory 15. And use it in subevents
- the background image data may be included in each processor. Further, only the background image data used in the sub-event may be stored in the display data memory 15, and the background image data used in the main event may be provided in each processor.
- the display system can display a plurality of information as an image, and can be expressed as a display system characterized in that data for displaying the image is generated by sharing a plurality of processors. .
- the display system of the present invention can be widely used as an information display system in vehicles such as automobiles and trains, aircraft, ships and the like.
