INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## Abstract A PC includes: a desktop display management section causing a display device to display, among desktops, a main or sub desktop by switching between these desktops, the sub desktop being associated with the main desktop; and an application program execution process section executing application programs and displaying images on the main and sub desktops, the images being generated by execution of the application programs, respectively. The desktop display management section switches the main desktop to the sub desktop by a start instruction to start the application program of the image on the sub desktop. ## Claims ### Claim 1 An image display control device, comprising: a desktop display switching section for causing a display device to display, of a plurality of desktops, a first desktop or a second desktop by switching between the first desktop and the second desktop, the second desktop being associated with the first desktop; and an application program execution processing section for (i) executing a first application program for the first desktop and a second application program for the second desktop and (ii) displaying a first image on the first desktop and a second image on the second desktop, the first and second images being generated in response to execution of the first and second application programs, respectively, the desktop display switching section switching the first desktop to the second desktop in accordance with a selection instruction to select the second application program of the second image displayed on the second desktop. ### Claim 2 (depends on 1) The image display control device according to claim 1, wherein the desktop display switching section switches the second desktop to the first desktop in response to end of display of the second image on the second desktop. ### Claim 3 (depends on 1) The image display control device according to claim 1, wherein: the display device is a liquid crystal display device including a touch panel; the second application program is a screen-saver program; the desktop display switching section switches the first desktop to the second desktop upon receipt of, as the selection instruction, an instruction to turn off a backlight provided in the liquid crystal display device, the instruction being generated in a case where the touch panel is not touched for a certain time period; the application program execution processing section executes the screen-saver program, so as to cause the second desktop to display a screen-saver image, and the application program execution processing section ends the second application program after touching to the touch panel carried out while the screen-saver image is displayed is released. ### Claim 4 An image display control device which causes a liquid crystal display device to display an image generated in response to execution of an application program, the liquid crystal display device including (i) a liquid crystal display panel provided with a backlight and (ii) a touch panel stacked on the liquid crystal display panel, said image display control device, comprising: a desktop display switching section for switching, of a plurality of desktops, a first desktop to a second desktop which is associated with the first desktop and displaying the second desktop, in response to turning-off of the backlight, the turning-off occurring in a case where the touch panel is not touched for a certain time period; a screen-saver display control section for causing the second desktop to display a screen-saver image; and a backlight control section for recognizing, in a case where the touch panel is touched while the backlight is off and the screen-saver image is displayed, the touching as an instruction to turn on the backlight. ### Claim 5 (depends on 4) The image display control device according to claim 4, wherein: the desktop display switching section switches the second desktop, which is displayed, to the first desktop in response to end of display of the screen-saver image; and the screen-saver display control section ends display of the screen-saver image, immediately after or a certain time period after the touching to the touch panel is released while the screen-saver image is displayed. ### Claim 6 (depends on 4) The image display control device according to claim 4, wherein: in a system including a plurality of liquid crystal display devices each including the liquid crystal display panel, the backlight, and the touch panel, the screen-saver display control section causes each of the liquid crystal display panels to display the screen-saver image, and causes each of the liquid crystal display panels to end display of the screen-saver image.
