Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable telephone capable of browsing information such as characters and images, and more particularly to a method of displaying the information.

[0002]

2. Description of the Related Art In a portable telephone capable of browsing information such as characters and images, the size of a display device is limited due to the nature of the portable telephone, and the number of characters is generally less than several hundred characters.

FIG. 2 is a block diagram showing an example of the configuration of a generally conceivable mobile phone capable of browsing information.

In FIG. 1, reference numeral 1 denotes an RF circuit for receiving a radio wave transmitted from a wireless network, 2 denotes an information receiving circuit for processing a signal obtained by the RF circuit 1 as information, and 3 denotes a liquid crystal for displaying information. A liquid crystal driver 4 for controlling and transferring information to the liquid crystal is a liquid crystal display device for displaying information.

When browsing information such as characters and images, R
The information received by the F circuit 1 is processed by the information processing circuit 2 as information corresponding to the display screen size,
The image is displayed on the liquid crystal display device 4 via the liquid crystal driver 3.

[0006]

However, when a large display device is mounted on the portable telephone, the portability is impaired. Therefore, the maximum limit is about 2 inches. In a display device of about 2 inches, characters and images cannot be recognized even when 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 separately displayed.

The number of characters displayed in the horizontal direction is typically 10 characters or less, which is not suitable for reading text.

There are also homepages and the like in which the number of characters in the horizontal direction is limited only by characters in consideration of connection from a mobile phone, but not all homepages are compatible.

[0009]

A portable telephone with an information display function according to the present invention comprises a display device for displaying information and a monitor output terminal connected to an external monitor and capable of displaying information. The monitor output terminal is configured to output information in a range wider than the display range of the display device.

In the portable telephone with an information display function according to the present invention, the connection to the monitor output terminal is detected to change the output to the display device and the output to the monitor output terminal. is there.

The mobile phone with an information display function according to claim 1, wherein the display size of the monitor output can be arbitrarily set.

[0012]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a block diagram showing a configuration example of a mobile phone with an information display function according to the present invention.

In FIG. 1, reference numeral 1 denotes an RF circuit for receiving a radio wave transmitted from a wireless network, 2 denotes an information receiving circuit for processing a signal obtained by the RF circuit 1 as information, and 3 denotes a liquid crystal for displaying information. A liquid crystal driver for controlling and transferring information to the liquid crystal; 4, a liquid crystal display device for displaying information;
Is a monitor driver for transferring information to an external monitor.

When browsing information such as characters and images, R
The information received by the F circuit 1 is processed by the information processing circuit 2 as information corresponding to the display screen size,
The image is displayed on the liquid crystal display device 4 via the liquid crystal driver 3.

At this time, if an external monitor is connected, the information processing circuit 2 processes the information as information corresponding to the display screen size of the external monitor.
And is displayed on an external monitor via a monitor output terminal (not shown). 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 unit and a control unit (not shown) of the mobile phone. The control means (not shown) detects whether or not the external monitor is connected to the monitor output terminal. If the external monitor is connected, the control means performs processing according to the large screen size set for browsing on the external monitor. The information receiving circuit 2 causes the information receiving circuit 2 to perform a process according to a normal small screen size for browsing on the built-in liquid crystal display device 4 when not connected.

[0016]

As described above, the present invention comprises a display device for displaying information and a monitor output terminal connectable to an external monitor such as a television, and the monitor output terminal has a display range of the display device. It is configured to output a wider range of information.

Accordingly, when an external monitor is connected, a television monitor or a monitor for a personal computer can be used as the external monitor, so that a display equivalent to that when the personal computer is connected to the Internet can be obtained.

Further, it is possible to browse not only the homepage in consideration of the connection from the mobile phone but also all the homepages without stress.

Also, since a personal computer or the like is not required, and since it is a mobile phone, there is no need to connect a telephone line or the like, it is extremely easy to enjoy a full-screen Internet connection in an environment with an external monitor such as at home. it can.

In addition, with the configuration according to the second aspect, the display size is automatically changed only by connecting the external monitor terminal, so that a mobile phone having an information display function that is more convenient to use is obtained.

Further, with the configuration according to the third aspect, in the case of a monitor having a relatively low resolution such as a television monitor or a small monitor, the size of characters to be displayed is increased. Increasing the visibility and increasing the amount of information that can be displayed on one screen at a time by reducing the font size for PC monitors and large TV monitors, and with an information display function that supports all situations Mobile phone.
