Description

The present invention relates to information display system, particularly, is suitably applied to the information display sheet, such as electronic paper.

Regarding printing of information on paper (so-called hard copy), since it has been used for a long time and has been improved, an excellent printing technique has been established.

Further, when the high-speed CPU 23 captures content data or the like via the data interface 22, the content data or the like can be sent to the information display sheet 1 via the connection units 10 and 28 and stored in the data storage unit 4. Further, the high-speed CPU 23 sends parameters and the like about the processing progress 6a (display page, data development necessary for display, etc.) performed on the host display processing device 21 side to the information display sheet 1 to the data storage unit 4. You may make it memorize | store. Further, when processing is performed in the media mode, the battery 5 may be charged via the connection units 10 and 28.

  On the other hand, when processing is performed in the stand-alone mode, the signal buses B1 and B2 are disconnected from each other and the power supply lines L1 and L2 are disconnected from each other by disconnecting the connection units 10 and 28 from each other. When the signal buses B1 and B2 are disconnected from each other, the connection control unit 9 connects the data storage unit 4, the low-capacity ROM / RAM 6 and the display drive unit 7 to the low-speed CPU 8 and the battery 5.

  Then, when the data storage unit 4 of the information display sheet 1, the low-capacity ROM / RAM 6, the display drive unit 7, the low-speed CPU 8 and the battery 5 are connected to each other, the low-speed CPU 8 reads the document data based on an instruction from the operation unit 3.

It is possible to give the information display sheet 1 advanced information processing capability.

  However, the content that can be processed by the low-speed CPU 8 by itself may be limited due to limitations on resources and processing speed. For example, processing such as tracing hyperlinks on the memory display panel 2 may not be continued because the linked content data is not in the information display sheet 1. For this reason, the low-speed CPU 8 can store the processing request 6b in the low-capacity ROM / RAM 6 when the processing request 6b that cannot be processed autonomously on the information display sheet 1 side is generated.

  As a result, when the information display sheet 1 is operated alone, the information display sheet 1 is connected to the host display processing device 21 even when an operation requesting a process that cannot be executed by the information display sheet 1 alone is performed. The host display processing device 21 can be made to perform processing corresponding to the operation performed on the information display sheet 1 in accordance with the timing when the information is displayed. Therefore, in order to cause the host display processing device 21 to perform processing that cannot be executed by the information display sheet 1 alone, it is not necessary to keep the information display sheet 1 connected to the host display processing device 21 at all times. While maintaining the convenience of carrying 1 and the like, it is possible to cope with various processing of document data on the premise of advanced information processing.

However, when a processing request 6b that cannot be processed autonomously on the information display sheet 1 side is generated, it is preferable to display a message for prompting connection with the host display processing device 21 on the memory display panel 2.
When processing is performed again in the media mode, the high speed CPU 23 can refer to the low-capacity ROM / RAM 6 to check whether the processing request 6b is stored in the low-capacity ROM / RAM 6. Then, when the processing request 6b is stored in the low-capacity ROM / RAM 6, the high-speed CPU 23 performs various processes on the document data 4a based on the processing request 6b, and transmits content data and the like via the data interface 22. Can be taken in. Then, when drawing data is generated by the graphic accelerator 25, the drawing data can be written in the drawing data writing unit 7a. When the drawing data is written in the drawing data writing unit 7a, the display driving unit 7 drives the X driver and Y driver of the memory display panel 2 to display the drawing data on the memory display panel 2. Can be made. Also, high-speed CPU23 includes a write-free take such as content data based on the processing request 6b, can be stored like the data storage unit 4 the content data.

Note that, when the high-speed CPU 23 performs processing based on the processing request 6 b stored in the low-capacity ROM / RAM 6, the high-speed CPU 23 may display that effect on the memory display panel 2. Moreover, you may make it request | require approval by a user as needed.
