Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mobile phone capable of browsing information such as characters and images, and more particularly to an information display method thereof.
[0002]
[Prior art]
A mobile phone capable of browsing information such as characters and images has a limit on the size of the display device due to the nature of the mobile phone, and generally has a number of characters of several hundred characters or less.
[0003]
FIG. 2 is a block diagram illustrating a configuration example of a mobile phone capable of generally browsing information.
[0004]
In the figure, 1 is an RF circuit that receives radio waves transmitted from a wireless network, 2 is an information receiving circuit that processes signals obtained by the RF circuit 1 as information, and 3 is a liquid crystal that controls a liquid crystal for displaying information. A liquid crystal driver 4 for transferring information to a liquid crystal display 4 is a liquid crystal display device for displaying information.
[0005]
When browsing information such as characters and images, the information received by the RF circuit 1 is processed as information matched to the display screen size by the information processing circuit 2 and is sent to the liquid crystal display device 4 via the liquid crystal driver 3. Is displayed.
[0006]
[Problems to be solved by the invention]
However, if a large display device is installed due to the nature of a cellular phone, the portability is impaired, so the maximum is about 2 inches. In a display device of about 2 inches, characters and images cannot be recognized even if a display in which an image and character information are mixed as seen on a normal Internet homepage is performed. Therefore, in many cases, only characters are displayed or images and characters are displayed separately.
[0007]
Also, the standard number of characters displayed in the horizontal direction is 10 characters or less, which is not suitable for reading a sentence.
[0008]
In addition, there are homepages and the like that limit the number of characters in the horizontal direction using only characters in consideration of connection from a mobile phone, but not all homepages are supported.
[0009]
[Means for Solving the Problems]
In order to solve the above problems, a mobile phone with an information display function according to the present invention is provided.
A display device for displaying information;
It has a monitor output terminal that can be connected to an external monitor and display information.
The monitor output terminal is configured to output information in a wider range than the display range of the display device.
[0010]
Further, in the mobile phone with an information display function according to claim 1, the connection to the monitor output terminal is detected and the output to the display device and the output to the monitor output terminal are changed.
[0011]
The mobile phone with an information display function according to claim 1, wherein a display size of the monitor output can be arbitrarily set.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram illustrating a configuration example of a mobile phone with an information display function according to the present invention.
[0013]
In the figure, 1 is an RF circuit that receives radio waves transmitted from a wireless network, 2 is an information receiving circuit that processes signals obtained by the RF circuit 1 as information, and 3 is a liquid crystal that controls a liquid crystal for displaying information. A liquid crystal driver 4 for passing information to 4, a liquid crystal display device 4 for displaying information, and a monitor driver 5 for transferring information to an external monitor.
[0014]
When browsing information such as characters and images, the information received by the RF circuit 1 is processed as information matched to the display screen size by the information processing circuit 2 and is sent to the liquid crystal display device 4 via the liquid crystal driver 3. Is displayed.
[0015]
At this time, if an external monitor is connected, it is processed by the information processing circuit 2 as information in accordance with the display screen size of the external monitor, and the external monitor is connected via the monitor driver 5 and a monitor output terminal (not shown). Is displayed. The display size of the external monitor output can be changed to an arbitrary size such as a full screen size by an operation input means and a control means (not shown) of the mobile phone. The control means (not shown) detects whether or not an external monitor is connected to the monitor output terminal, and if it is connected, performs processing according to the large screen size set for viewing on the external monitor. When the information receiving circuit 2 is not connected, the information receiving circuit 2 performs processing corresponding to a normal small screen size for viewing on the built-in liquid crystal display device 4.
[0016]
【The invention's effect】
As described above, the present invention includes a display device for displaying information and a monitor output terminal that can be connected to an external monitor such as a television, and the monitor output terminal has a wider range than the display range of the display device. It is configured to output information.
[0017]
Accordingly, when an external monitor is connected, a TV monitor, a personal computer monitor, and the like can be considered as the external monitor, so that a display equivalent to that obtained when a personal computer is connected to the Internet can be obtained.
[0018]
In addition, it is possible to browse all homepages without stress as well as homepages that consider connections from mobile phones.
[0019]
In addition, since it is a mobile phone and does not require a personal computer or the like, it is not necessary to connect a telephone line or the like. Therefore, in an environment with an external monitor such as a home, a full-screen Internet connection can be enjoyed very easily.
[0020]
Further, with the configuration as shown in claim 2, since the display size is automatically changed simply by connecting the external monitor terminal, the mobile phone with an information display function is more convenient.
[0021]
Furthermore, when configured as shown in claim 3, in the case of a monitor with a relatively low resolution such as a television monitor or a small monitor, visibility can be improved by increasing the size of characters to be displayed. In the case of PC monitors and large TV monitors, the amount of information that can be displayed on a single screen can be increased by reducing the character size. It becomes.
