Abstract

A display apparatus includes: a display device that displays a plurality of images in a first row, an operation of an application program being assigned to each of the images; a rearrangement device that rearranges the plurality of images, when a portion of the first row is specified, such that the specified portion is at an opened facing page section; an execution device that executes the operation of the application program corresponding to an image located at the opened facing page section when the opened facing page section is specified; and a display control device that controls the display device, when the operation is executed by the execution device, to perform a display according to the operation executed.

Claims

1. A display apparatus comprising:

a display device that displays a plurality of images in a first row, an operation of an application program being assigned to each of the images;

a rearrangement device that rearranges the plurality of images, when a portion of the first row is specified, such that the specified portion is at an opened facing page section;

an execution device that executes the operation of the application program corresponding to an image located at the opened facing page section when the opened facing page section is specified; and

a display control device that controls the display device, when the operation is executed by the execution device, to perform a display according to the operation executed.

2. A display apparatus according to claim 1, wherein the operation of the application program is an operation of newly displaying a plurality of images, each being assigned with an operation of an application program, in a second row different from the first row.

3. A display apparatus according to claim 2, wherein, when a portion among the second row is specified, the display control device displays a plurality of images, each of the images being assigned with an operation of an application program, in a third row in a predetermined direction with respect to the first row as viewed from the second row.

4. A display apparatus according to claim 1, wherein each of the plurality of images to be displayed according to the operation executed corresponds to an application program or contents.

5. A display apparatus according to claim 1, wherein

the display device includes a plurality of pixels,

the gray level of the plurality of pixels is changed by a write operation of applying a voltage to each of the pixels a plurality of times,

the display control device compares image data indicative of an image to be newly displayed at the display device with scheduled image data indicative of an image scheduled to be displayed at the display device by the write operation in progress, thereby judging as to which pixels among the plurality of pixels are to change the gray level,

when pixels that are judged to be those of the pixels whose gray level is to be changed are not in the write operation, the display control device starts the write operation on the pixels to have a gray level specified by the image data, and

when pixels that are judged to be those of the pixels whose gray level is to be changed are in the write operation, the display control device starts the write operation on the pixels to have a gray level specified by the image data upon completion of the write operation in progress.

6. An electronic apparatus comprising the display apparatus recited in claim 1.

7. A display control method comprising the steps of:

displaying a plurality of images, each of the images being assigned with an operation of an application program, in a first row at a display device;

rearranging the plurality of images, when a portion of the first row is specified, such that the specified portion is at an opened facing page section;

executing the operation of the application program corresponding to an image located at the opened facing page section when the opened facing page section is specified; and

controlling the display device, when the operation is executed, to perform a display according to the operation executed.
