Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid crystal display device with a built-in strobe and a digital camera. More specifically, the present invention relates to a liquid crystal display device with a digital camera used for a display of a portable information terminal such as a mobile phone.

[0002]

2. Description of the Related Art Since a conventional image display device such as a cellular phone has no function other than displaying information, a digital camera or a strobe light source is separately connected or used when taking a digital image. I had to. As a result, there has been inconvenience in portability as a mobile phone or a portable information terminal.

[0003]

FIG. 2 shows a configuration of a conventional portable telephone. Reference numeral 11 denotes a mobile phone, 12 denotes a digital camera, 13 denotes a connection cable for them, and 14 denotes a liquid crystal module of the mobile phone. The configuration of the conventional mobile phone configured as described above will be described below. When sending a digital camera image using a morphological information terminal such as a mobile phone, the connection cable 13 is usually connected to the mobile phone 11.
, The digital camera 12 needs to be connected. Further, when the subject is too dark, there is a case where the shooting quality is deteriorated due to insufficient exposure.

As described above, the conventional technique has a problem that it is inconvenient for portability such that an external strobe or the like needs to be prepared for photographing in darkness.

An object of the present invention is to solve the above-mentioned conventional problems, and an object of the present invention is to provide a liquid crystal display device using a backlight of the liquid crystal display device as a strobe light source.

[0006]

In order to achieve the above object, a liquid crystal display device with a digital camera according to the present invention comprises a liquid crystal module, a digital camera built in the liquid crystal module, and a flash built in the liquid crystal module. It is characterized by being composed of light sources, which are integrated.

It is preferable that the digital camera is provided inside a panel or a backlight of the liquid crystal module, and has a function of photographing the liquid crystal module.

The strobe light source has a common structure with a backlight module of a liquid crystal module.
It is preferable that the backlight itself has a function as a strobe light source.

It is preferable that a lens unit of the digital camera is provided on the back of a liquid crystal display screen, and that the digital camera has a function of improving image quality by adjusting image display on a liquid crystal panel between the digital camera and a subject.

It is preferable that the digital camera-equipped liquid crystal display device also serves as a portable information terminal display.

As described above, according to the present invention, a backlight in a liquid crystal display device is used also as a strobe light source, and a digital camera is incorporated in the liquid crystal device.
Thus, a mobile phone or a portable information terminal having excellent portability can be provided.

(Embodiment 1) Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG.
FIG. 1 is a schematic explanatory diagram in which a digital camera and a strobe light source according to an embodiment of the present invention are integrated with a liquid crystal display device. In FIG. 1, reference numeral 21 denotes a backlight module;
2 is a liquid crystal panel, 23 is a backlight / strobe light emitting surface, 24 is a digital camera, 25 is a mobile phone, and 26 is a subject. A digital camera 24 is embedded in the backlight module 21, and when taking a picture, the picture can be taken through the liquid crystal panel 22. For example, when taking a picture, the digital camera 24 takes a picture through the liquid crystal panel 22, so that it is somewhat affected by the image displayed on the liquid crystal panel. However, when the display around the lens portion of the digital camera 24 or the entire range of the liquid crystal panel 22 is made a single color such as white, a higher quality image can be obtained.

The backlight module 21 functions as a strobe light source, and can use the light to brighten the subject 26 when taking a picture. That is, by simply pointing the liquid crystal display unit to the subject 26 at the time of shooting, both the lens unit of the camera and the strobe light source are directed to the subject. The brightness of the backlight module 21 is preferably in the range of 100,000 to 50,000 Cd (candela) in order to function as a strobe light source.

[0014] Also, when used in a videophone format,
By performing the conversation while watching the image of the other party reflected on the liquid crystal display unit, it is possible to realize a conversation without discomfort because their eyes are aligned with the image. 1000C in this case
Use in the range of d (candela). Note that the brightness is switched by controlling the amount of current supplied to the backlight.

As described above, according to the embodiment of the present invention, a digital camera and a strobe light source can be integrated into a liquid crystal display device, so that the portability as a portable information terminal is improved. It has the effect of doing.

The same effect can be obtained by arranging the charge-coupled device (CCD) of the digital camera 24 in or on the liquid crystal panel.

[0017]

As described above, according to the present invention, since a digital camera and a strobe light source can be integrated into a liquid crystal display device, the portability as a portable information terminal can be improved. Play.
