DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable electronic device, and more particularly to an illuminated electronic device whose display portion is illuminated so as to be easily viewed.

[0002]

2. Description of the Related Art Heretofore, there has been known a portable electronic device in which a display unit composed of a liquid crystal screen is provided in an apparatus main body. By the way, the lighting of this type of display is
For example, as shown in Japanese Patent Application Publication No. 60-501181, a back lighting is known in which a lighting is provided on the back side of a display unit and the lighting unit illuminates the display unit from the back side.

[0003]

However, this type of backlight has the following problems. A first problem is that, as shown in FIG. 4, the thickness of the device main body 1 increases as the thickness of the display unit 2 of the device main body 1 of the electronic device increases. The reason is that when lighting is performed from the back of the LCD, an element for lighting such as an EL or an LED module is required on the back of the LCD. The second problem is that
The point is that the contrast of the LCD is reduced. The reason is that when lighting is done from the back of the LCD,
This is because it is necessary to transmit light, and the reflecting plate attached to the back surface of the LCD needs to be a semi-transmitting plate. A third problem is that the cost of the apparatus is increasing. The reason is,
This is because if the lighting is built into the device, it is necessary for a person who does not need the lighting to bear the cost for the lighting.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to provide an illuminated electronic device in which a display unit capable of suppressing an increase in thickness and reducing costs can be easily viewed. And

[0005]

In order to achieve the above object, an illuminated electronic device according to the first aspect of the present invention has a liquid crystal display.
A device body having a display unit is provided comprising, openably provided in the apparatus main body, the electronic apparatus having a lid for protecting the display unit, to the lid, capable Lighting is provided the display unit It is characterized by that. An electronic device with illumination according to a second aspect is the electronic device with illumination according to the first aspect, wherein the lid is provided with an illumination circuit for driving the illumination. According to a third aspect of the present invention, there is provided the electronic device with illumination according to the first aspect, wherein the illumination includes a surface-emitting element.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of an illuminated electronic device according to the present invention. In FIG. 1, reference numeral 1 denotes an apparatus main body constituting an electronic apparatus, and the apparatus main body 1 is provided with a display unit 2 formed of a liquid crystal screen. Further, a lid 3 is attached to the apparatus body 1 so as to be openable and closable, and the display unit 2 is protected by closing the lid 3. A lamp (illumination) 4 is provided on a lid 3 constituting the electronic device. The lamp 4 is driven by an illumination circuit 5 provided on the lid 3, and is turned on by being driven by the illumination circuit 5 to illuminate the display unit 2.

When it is desired to illuminate the display unit 2 of the electronic apparatus, the display unit 2 can be illuminated very easily by operating the illumination circuit 5 provided on the lid 3. As described above, the display unit 2 attached to the apparatus main body 1
According to the electronic device in which the cover 3 for protecting the display is provided with the illumination, the cover 3 for protecting the display unit 2 is provided with the illumination including the lamp 4, so that the thickness of the display portion of the display unit 2 can be reduced. Thus, unlike the conventional backlight-type electronic device, the device main body 1 provided with the display portion does not become thick, and the electronic device can be made more compact.

Further, the reflecting plate provided on the back surface of the display unit 2 can be a total reflecting plate without being a translucent plate,
Thereby, the contrast of the display unit 2 can be improved. In the case where lighting is not required, as shown in FIG. 3, an electronic device having an inexpensive lid 3 having no lighting function can be provided.

Next, an electronic device with illumination according to another embodiment will be described. As shown in FIG. 2, the electronic device with illumination includes a cover 3 of the electronic device provided with illumination including a surface light-emitting element 11, and the illumination circuit 5 provided on the lid 3 provides the surface light-emitting element. 11 is driven as needed. Then, according to the electronic device in which the surface light emitting element 11 is provided on the lid 3, the entire display unit 2 of the apparatus main body 1 can be illuminated, and the display portion of the display unit 2 can be further easily viewed.

[0010]

As described above, according to the electronic device with illumination of the present invention, the following effects can be obtained. According to the illuminated electronic device of the first aspect, the illumination is provided on the lid that protects the display unit, so that the thickness of the display unit by the display unit can be reduced. In addition, the thickness of an apparatus main body provided with a display portion, unlike a backlight-type electronic device in which illumination is provided on the back of a liquid crystal screen, does not increase, and the electronic device can be made more compact. Also, as in the case of the back-lit type,
The reflection plate provided on the back surface of the crystal screen can be a total reflection plate without being a translucent plate, whereby the contrast of the display unit can be improved. In the case where lighting is not required, an electronic device having an inexpensive lid without a lighting function can be provided.

According to the electronic device with illumination according to the second aspect, when it is desired to illuminate the display section of the electronic apparatus, the display section can be illuminated extremely easily by operating the illumination circuit provided on the lid. . That is, the display unit can be illuminated by the illumination as needed. According to the electronic device with illumination according to claim 3, since the illumination provided on the lid is made of a surface light emitting element, the entire display section of the apparatus main body can be illuminated, and the display section of the display section can be further illuminated. It can be easier to see.
