Abstract

A method for screen display on a touch screen is disclosed. The method is used on a touch screen, wherein the touch screen comprises a display area, and the display area has a first display boundary. The method includes: displaying a first document area of an electronic document within the display area, wherein the electronic document comprises a first document boundary; detecting a traveling path of an object; if the traveling path is determined as an “instruction of moving the electronic document in a first direction”, moving the electronic document in the first direction, and displaying a second document area of the electronic document within the display area; if the instruction exists and the first document boundary reaches the first display boundary, displays a deformed electronic document; and if the instruction no longer exists, stops the deformation.

when the third document area is deformed, the background color of the third document area is mixed with the first background color and the second background color.

4. The screen display method applicable on a touch screen as claimed in claim 2, wherein the third document area of the electronic document in original size and the fourth document area of the electronic document in the original size are displayed at the same magnification.

5. The screen display method applicable on a touch screen as claimed in claim 3, wherein the second background color is black, gray, or a dark color.

6. The screen display method applicable on a touch screen as claimed in claim 3, wherein the first background color is visually distinct from the second background color.

7. The screen display method applicable on a touch screen as claimed in claim 1, wherein moving the electronic document in the first direction prior to reaching the first display boundary has an associated moving distance that corresponds to a distance of the traveling path of the object.

8. The screen display method applicable on a touch screen as claimed in claim 1, wherein moving the electronic document in the first direction prior to reaching the first display boundary has an associated moving speed that corresponds to a speed of the traveling path of the object.

9. The screen display method applicable on a touch screen as claimed in claim 1, wherein the first document boundary appears to be elastically attached to the first display boundary.

10. A screen display method applicable to a touch screen, the touch screen having a display area, the display area having a first display boundary and a second display boundary opposite to each other, the method comprising:

displaying a first document area of an electronic document within the display area, wherein the electronic document comprises a first document boundary and a second document boundary opposite to each other;

detecting a plurality of movement trajectories of a plurality of objects touching or being close to the touch screen;

when the plurality of movement trajectories are determined as an “

instruction of zooming out the electronic document”

, zooming out the electronic document, and displaying a second document area of the electronic document within the display area, wherein the second document area includes the first document area;

when the “

instruction of zooming out the electronic document”

exists and the first document boundary reaches the first display boundary and the second document boundary reaches the second display boundary, executing the following step;

displaying a third document area of the electronic document with extending deformation toward the center of the electronic document, the first document boundary simultaneously matching the first display boundary, and the second document boundary simultaneously matching the second display boundary, wherein the third document area being a portion of the electronic document adjacent to one of the first document boundary and the second document boundary, and

displaying a fourth document area of the electronic document with compression deformation toward the center of the electronic document, wherein the fourth document area being a portion of the electronic document distant from the first document boundary and the second document boundary;
