Abstract

A dual-screen electronic reading apparatus includes a memory storing files, a non-volatile display unit, a volatile display unit, and a microprocessor. The microprocessor includes a file determining module configured for determining whether text and at least one image exist in one opened file, and for generating a text file and an image file if both text and at least one image exist in the opened file. The microprocessor also includes a display controlling module configured for displaying the text file on the non-volatile display unit and displaying the image file on the volatile display unit.

Claims

1. A dual-screen electronic reading apparatus, comprising:

a memory storing a plurality of files;

a non-volatile display unit;

a volatile display unit; and

a microprocessor comprising;

a file determining module determining whether text and at least one image exist in one opened file, generating a text file if text exists in the opened file, and generating an image file if at least one image exists in the opened file, wherein the text file records the text of the opened file and at least one marker, the at least one marker indicating a display position of the at least one image in the opened file, and the image file records the at least one image and at least one identifier, the at least one identifier corresponding to the at least one marker; and

a display controlling module displaying the text file on the non-volatile display unit and the image file on the volatile display unit simultaneously, wherein displaying the text file comprises displaying the text and the at least one marker, and wherein displaying the image file comprises displaying the at least one image on the volatile display unit according to the presence of the at least one marker on the non-volatile display unit and a relationship between the at least one identifier of the image and the at least one marker.

2. The electronic reading apparatus as described in claim 1, wherein if the file determining module determines that only text exists in the opened file, the display controlling module displays the opened file on the non-volatile display unit.

3. The electronic reading apparatus as described in claim 1, wherein if the file determining module determines only the images exist in the opened file, the display controlling module displays the opened file on the volatile display unit.

4. The electronic reading apparatus as described in claim 1, wherein the non-volatile display unit is an electrophoretic display, and the volatile display unit is an Liquid Crystal Display or a Cathode-Ray Tube.

5. The electronic reading apparatus as described in claim 1, further comprising an interface unit transmitting files from an external storage device to the memory.

6. A display method applied in a dual-screen electronic reading apparatus, comprising:

providing the dual screen electronic reading apparatus comprising a non-volatile display unit and a volatile display unit;

opening and reading one file in response to an opening signal generated in response to a user operation;

determining whether text and at least one image exist in the opened file;

generating a text file if text exists in the opened file, and generating an image file if at least one image exists in the opened file, wherein the text file records the text of the opened file and at least one marker, the at least one markers indicating a display position of the at least one image in the opened file, and the image file records the at least one image and at least one identifier, the at least one identifier corresponding to the at least one markers; and

displaying the text file on the non-volatile display unit and the image file on the volatile display unit simultaneously, wherein displaying the text file comprises displaying the text and the at least one marker, and wherein displaying the image file comprises displaying the at least one image on the volatile display unit according to the presence of the at least one marker on the non-volatile display unit and a relationship between the at least one identifier of the image and the at least one marker.

7. The display method as described in claim 6, further comprising:

determining if only the text exists in the opened file; and

displaying the opened file on the non-volatile display unit if only the text exists in the opened file.

8. The display method as described in claim 6 further comprising:

determining if only the at least one images exists in the opened file; and

displaying the opened file on the volatile display unit if only the at least one images exists in the opened file.

9. The display method as described in claim 6, wherein the non-volatile display unit is an electrophoretic display, and the volatile display unit is an Liquid Crystal Display or a Cathode-Ray Tube.
