No. 13/112,164, filed May 20, 2011 and U.S. application Ser. No. 12/318,604, filed Dec. 31, 2008 (now U.S. Reissue Pat. No. Re. 42,616). The present application is a continuation application of U.S. application Ser. No. 12/318,604, filed Dec. 31, 2008 now U.S. Pat. No. Re. 42,616.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates method and apparatus for controlling a display mode in a portable computer.
2. Background of the Related Art
Tablet computers have been developed on the basis of advantageous effects of desktop, notebook and handheld computers. A notebook computer is referred to as a mobile computer. But, when the notebook computer is used, its main body must be positioned on a fixed base surface. Meanwhile, a tablet computer can be easily used on a user's hand like a personal digital assistant (PDA). The tablet computer enables the user to directly take notes on a monitor using an electronic pen in place of a keyboard. Since an input unit in the tablet computer is based upon a touch screen, a special input unit such as a mouse is not necessary, and hence, the tablet computer can be conveniently used. Thus, the tablet computer has excellent mobility and convenience. Furthermore, since the tablet computer includes the computer's basic components inside the monitor, its exterior is simple. A portable computer can implement the notebook computer function and the tablet computer function in a single system in order for the user to conveniently and selectively use a notebook computer function and a tablet computer function.
A prior art portable computer automatically converts a display mode of its display to a landscape or portrait mode, which is a corresponding default display mode for a converted system mode when the system mode is converted from a notebook mode into a tablet mode or vice versa, or when a docking device is connected. For example, a display operation of the display is carried out in the landscape mode when the system mode is converted into the notebook mode as shown in FIG. 2, and the display operation of the display is carried out in the portrait mode when the system mode is converted into the tablet mode as shown in FIG. 3. When the docking device is connected to the prior art portable computer, the display operation of the display is carried out in the landscape or portrait mode set appropriately to an application program of the connected docking device. Thus, the default display mode predetermined to be the most appropriate for the system mode is automatically set.
Since the prior art portable computer automatically forces the display to carry out the display operation in only one display mode previously determined for a system mode or a docking device when the system mode is converted or the docking device is connected, the display mode of the display cannot be arbitrarily changed to the user-desired display mode. For example, the display operation of the display cannot be automatically carried out in the portrait mode when the system mode is converted into the notebook mode. Further, the display operation of the display cannot be automatically carried out in the landscape mode when the system mode is converted into the tablet mode. Consequently, the user cannot change the LCD display mode automatically to various display modes other than the previously determined display mode.
In addition, the prior art portable computer outputs a wallpaper image of a predetermined aspect ratio such as a landscape mode having an aspect ratio of ‘1024×768’ to the display as shown in FIG. 4. The wallpaper image may consist of a logo of a portable computer manufacturer, a particular background picture, etc.
When a user requests, for example using a touch screen digitizer or a keyboard (not shown), a display mode of the display to be converted from the landscape mode into the portrait mode or a 90 degree rotational mode in which the display operation of the display is carried out in a direction rotated by 90 degrees, the display mode of the display is changed to the requested portrait mode or 90 degree rotational mode. However, the landscape wallpaper image having the aspect ratio of ‘1024×768’ is converted into a resized portrait wallpaper image having an aspect ratio of ‘768×1024’ or ‘600×800’ or a wallpaper image that is rotated by 90 degrees and resized to have an aspect ratio of ‘1024×768’ by a video controller, and then, the converted wallpaper image is outputted to the display. Accordingly, there is a problem in that a logo, a background pattern, or/and a background picture included in the wallpaper image are all displayed in a distorted state as shown in FIG. 4.
The above references are incorporated by reference herein where appropriate for appropriate teachings of additional or alternative details, features and/or technical background.

In order to set the display mode of a liquid crystal display (LCD), the booted OS can search for display mode information previously set for the currently booted system mode, for example by a user (block S11). The display mode information previously set by the user can be LCD display mode information set for the sake of the user preference, task convenience or the like. The display mode information previously set can be stored in a storage medium such as an electrically erasable and programmable read only memory (EEPROM), hard disc or the like. Where the user does not set the display mode information previously, the OS can search for information of a default display mode for the currently booted system mode stored in the storage medium provided in the portable computer.
Then, the OS can determine whether or not the system can start while the LCD display mode is set to an arbitrary display mode previously set by the user rather than the default display mode for the currently booted system mode (block S12). If the LCD display mode cannot be set to the arbitrary display mode previously set by the user, the OS preferably sets the display mode of the LCD 13 to the landscape mode, the portrait mode, or the rotational display mode predetermined for the currently booted system mode or a docking device 16 connected to the portable computer (e.g., the default display mode) so that the LCD 13 can carry out the display operation in the set display mode (block S13). On the other hand, if the LCD display mode can be set to the arbitrary display mode previously set by the user, the OS sets the LCD display mode to an arbitrary display mode corresponding to the searched display mode information so that the LCD 13 can carry out the display operation in the set display mode (block S14).
The user can make a display mode change request when using the portable computer (block S15). When the user makes a display mode change request while the portable computer is used (block S15), the LCD display mode can be set to an arbitrary display mode selected by the user, the LCD 13 can perform the display operation in the set display mode, and information of the display mode changed by the user can be stored (block S16).
For example, where the user changes the display mode to the portrait mode when the LCD display mode is set to the landscape mode, which is the default display mode for the notebook mode of the current system mode, the display operation can be carried out in the portrait mode as shown in FIG. 6. In another example, where the user changes the display mode to the landscape mode in a state in which the LCD display mode is set to the portrait mode, which is the default display mode for the tablet mode of the current system mode, the display operation can be carried out in the landscape mode as shown in FIG. 7. Thus, upon a next transition to the tablet mode or system re-boot, the initial LCD display mode can be the landscape mode. Where the user arbitrarily changes the LCD display mode to the landscape or portrait mode through an input unit, the changed display mode information can be stored being associated with the current system mode in the EEPROM or hard disc.
Where the system is rebooted, where the system mode is converted from the notebook mode into the tablet mode or vice versa, or where the docking device is connected, in a state in which the display mode information is stored being associated with each system mode as described above (block S17), the OS can repeat the above blocks S11 to S14. The above-described operations can be continuously performed until the system is terminated (block S18).
FIG. 8 is a flow chart illustrating a method for controlling the display mode in the portable computer in accordance with another embodiment of the present invention. As shown in FIG. 8, the method for controlling a display mode in a portable computer will be described using and can be applied to various portable computer systems such as a notebook computer, a tablet computer, etc. that can be configured by the components shown in FIG. 1. However, the present invention is not intended to be so limited.
An operating system (OS) corresponding to a system mode selected by a user, for example, an OS for a notebook mode or an OS for a tablet mode can be directly or automatically booted in the portable computer when system power is turned on or enabled (block S10). The booted OS can determine whether or not the system can start while the LCD display mode is set to another display mode previously stored in storage medium (e.g., by a user) rather than a default display mode for the currently booted system mode (block S20). If the LCD display mode cannot be set to said another display mode previously stored in the storage medium for the currently booted system mode, the booted OS can set the LCD display mode to the default display mode for the currently booted system mode such that the LCD 13 can carry out the display operation in the set display mode (block S23). On the other hand, if the LCD display mode can be set to said another display mode previously stored for the currently booted system mode, the booted OS can search for information of the another display mode (e.g., by the user) stored in the storage medium (block S21) and set the LCD display mode to a display mode corresponding to the searched display mode information, such that the LCD 13 can carry out the display operation in the set display mode (block S22). As remaining processes in FIG. 8 were previously described, a description is omitted here.
As described above, block S12 shown in FIG. 5 and block S20 shown in FIG. 8 for allowing the OS to determine whether or not the system can start while the LCD display mode is set to another display mode previously stored in the storage medium (e.g., by a user) rather than the default display mode for the currently booted system mode are not necessarily required. In other words, embodiments according to the present invention can include only searching for the display mode information for the currently booted system mode from the storage medium; setting the LCD display mode to the searched display mode; and enabling the LCD to carry out the display operation in the set display mode. Thus, the block S12 and S13 shown in FIG. 5 as well as blocks S20 and S23 shown in FIG. 8 can be omitted.
Further in embodiments for controlling a display mode in the portable computer, a first display mode or the landscape mode can have an aspect ratio of ‘1024×768’. Another display mode can have an aspect ratio of ‘768×1024’, ‘600×800’, etc. other than the aspect ratio of the landscape mode. Said another display mode may be called a portrait mode. Also, there may be a rotational display mode. In the rotational display mode, an image displayed on the LCD 13 can be rotated, from a direction of the landscape mode, by 90 degrees, 180 degrees, or 270 degrees and resized to have the same aspect ratio of ‘1024×768’ as that of the landscape mode.
The rotational display mode in which an image displayed on the LCD 13 is rotated by 90 degrees and resized to have the same aspect ratio of the landscape mode can be called a 90 degree rotational mode. In order for a logo, a background pattern, or/and a background picture included in a wallpaper image displayed on the LCD 13 not to be distorted after the display mode is converted from the landscape mode into another display mode such as the portrait mode or the rotational mode, an original ratio of a horizontal width to a vertical length of the logo, the background pattern, or/and the background picture included in the wallpaper image must be maintained. According to embodiments of the present invention, a respective wallpaper image, in which the original ratio of the horizontal width to the vertical length of the logo, the background pattern, or/and the background picture is maintained, can be separately stored in a converted state for each display mode.
When a user makes a request for a conversion of the display mode of the LCD 13, for example, a display mode conversion from the landscape mode into the portrait mode or the rotational mode, or vice versa, the video controller 11 preferably can retrieve a wallpaper image for the requested display mode among every wallpaper image for each display mode, and output the retrieved wallpaper image to the LCD 13. Accordingly, as shown in FIG. 9, the wallpaper image in which the logo, the background pattern, or/and the background picture is not distorted can be displayed, irrespective of the converted display mode.
As described above, embodiments according to the present invention were described using an LCD as a display. However, the present invention is not intended to be so limited.
Various software of firmware layers (formed of modules or routines, for example), including applications, operating system modules, device drivers, BIOS modules, and interrupt handlers, may be stored in one or more storage media in the portable computer system. The storage media includes the hard disk drive, CD or DVD drive, floppy drive, non-volatile memory, and system memory. The modules, routines, or other layers stored in the storage media contain instructions that when executed causes the system to perform programmed acts.
The software or firmware layers can be loaded into the system in one of many different ways. For example, code segments sorted on floppy disks, CD or DVD media, the hard disk, or transported through a network interface card, modem, or other interface mechanism may be loaded into the system and executed as corresponding software or firmware layers. In the loading or transport process, data signals that are embodied as carrier wave (transmitted over telephone lines, network liens, wireless links, cables, and the like) may communicate the code segments to the system.
