    Illuminated display device and electronic device provided with the same
    BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an illumination type display device that displays names such as operation keys using dimming from light sources such as light emitting diodes, and an electronic device having the display device.
    First, with reference to FIGS. 4 to 7, an illumination display device according to the related art and an electronic device having the device will be described.
    4A is a plan view showing a display state as an example of a display device combined with a cabinet of a known electronic device, and FIG. 4B is another plan view showing another state in which the displayed item is partially turned off. FIG. 5A is a plan view showing a display state as another example of a display device combined with a cabinet of a known electronic device, and FIG. 5B is another plan view showing another state in which the displayed item is partially turned off. 6 is a partial cross-sectional view of an illuminated display device mounted on a known electronic device, and FIG. 7 is a plan view illustrating an inner surface of a transparent sheet used in the illuminated display device of FIG. 6.
    4A and 4B, reference numeral 20 denotes a cabinet of an electronic device such as a video camera (hereinafter simply referred to as a video camera) with a video tape recorder. The video camera has a camera shooting function as a main function and a recording / playback function as a sub function. The video camera may be selectively changed to a camera shooting mode or a recording / playback mode by a selection switch (not shown), and the selected mode is mounted on the front panel 21 of the cabinet 20 and the front portion of the cabinet 20. It is displayed on the display surface 11 of the illuminated display device (hereinafter, simply referred to as a display device).
    The item 22 displayed for the camera shooting function has a name of an operation key 23 having a start / stop mode switch, an AE lock switch button, a fader switch button, and a backlight compensation switch button. The name of the key is printed on the front panel 21 of the cabinet 20 by letters, marks or numbers.
    The item 12 displayed for the recording / playback function has a name of an operation key having a recording, playback, stop, fast forward, and rewind switch. The name is shown in letters, marks or numbers on the display surface 11 of the display device 10 in parallel with the item 22 described above. In the case of the item displayed in the video camera shown in Figs. 5A and 5B, the operation key 13 of the display item 12 for the recording / playback function and the operation key 23 of the display item 22 for the camera shooting function Are shown in parallel on the display surface 11 of the display device 10 as in the case described above. However, the difference from the above-described display method shown in FIGS. 4A and 4B is that instead of being displayed on the front panel 21 of the cabinet 20, the display item 22 of the camera shooting function is described as described later. It is printed on the surface of the display surface 11.
    The device 10 for displaying the name of the operation key 13 uses a light emitting diode L, for example, a light source for emitting dimming, and has a structure as shown in FIG. The light emitting diode L mounted on (1) and the transparent sheet 2 arrange | positioned at predetermined intervals from the light emitting diode L are included. On one side (inner side) of the transparent sheet 2 facing the light emitting diode L, a black character cutout backing layer 3 indicates the names of the operation keys 13 and the like of the recording / playback function, which are sub-functions. It is formed by printing the display item.
    According to the display method shown in Fig. 5, the display item 22 indicating the name of the operation key 23 of the camera shooting function as the main function is a transparent sheet at a position not overlapping with the position of the display item 12 of the recording / playback function. Is printed on the surface of (the opposite side to the light emitting diode L).
    The transparent sheet 2 may be made of, for example, a transparent polystyrene resin, a polycarbonate resin, an acrylic resin, a vinyl chloride resin, or the like.
    In Fig. 6, reference numeral 7 denotes a lens for diffusing dimming from the light emitting diode L, and also serves as a switch button. When the upper portion of the lens 7 is pressed down, the lens 7 is lowered to compress the switch button 8 disposed on the printed circuit board in the vicinity thereof to activate each function of the video camera.
    In the display device 10 having the above-described structure, a selection switch, which is not shown normally, is set on the camera shooting function side so that the display item 12 on the display surface 11 is turned off as shown in FIG. 4B or 5B. It seems to be nothing. The reason for this disappearance is that when the operation key 13 of the recording / playback function is displayed, since many operation keys are always displayed, there is a concern that a general user may give a false impression that the operation of the video camera is very complicated and difficult. Because there is.
    When a video camera is used as the video recording / reproducing apparatus, first the video camera is switched to receive power, and a selection switch (not shown) is changed from the camera shooting function side to the recording / playback function side, thereby to FIG. 4B or 5B. As shown, the display item 12 in the off state on the display surface 11 is lit as shown in Figs. 4A and 5A, and thus the display item 12 of the operation key 13 of the recording / playback function. ) Is displayed. In this case, the light emitting diode L is turned on when the selection switch (not shown) is changed to the recording / playback function side, so that the display item 12 of the recording / playback function is cut out in black lines as shown in Figs. 4A and 5A. It is lit and displayed on the transparent sheet 2 through the exclusive layer 3.
    However, in the display device 10, the cutout character is shown even when the light emitting diode L is turned off as shown in FIGS. 4B and 5B, and it is difficult to completely remove the appearance of the display item 12.
    If the surface of the cabinet 20 of a video camera, which is one of the electronic devices, is of metal or similar color, for example silver or gold, the video camera may have high quality sensitivity, but because the bottom color of the display device 10 is black, In the case where the front panel 21 of the cabinet 20 around the display surface 11 is of a predetermined metal color or similar color, for example silver or gold, the user may feel incompatibility with the color difference. The overall appearance of the camera is poor, and the camera cannot achieve the desired high quality sensitivity.
    SUMMARY OF THE INVENTION An object of the present invention is to provide a display device suitable for use in an electronic device in which the displayed characters and the like are completely invisible when dimming disappears, and when a color is displayed, the electronic device is harmonized with a predetermined metallic color or a similar color of a cabinet around the display surface.

    Hereinafter, preferred embodiments of the present invention will be described with reference to FIGS.
    1 is a partial cross-sectional view of an illuminated display device mounted on an electronic device that seals the present invention. FIG. 2A is a plan view showing one display state of the illuminated display device of the first embodiment assembled in the cabinet of the electronic device of FIG. 1, and FIG. 2B is a plan view of the first embodiment in another display state where the display item is partially turned off. . 3A is a plan view showing one display state of the illuminated display device of the second embodiment assembled in the cabinet of the electronic apparatus of the present invention, and FIG. 3B is a plan view of the second embodiment with the display item partially in another display state. .
    In the drawings, components corresponding to those in the aforementioned display device 10 of the prior art are denoted by the same reference numerals.
    First, the configuration of the display device according to the present invention will be described.
    1 and 2, reference numeral 10A denotes a display device of the present invention. The display device 10A further includes a light emitting diode L mounted on the printed circuit board 1 and a transparent sheet 2 spaced apart at a predetermined interval. On one surface (inner surface) of the transparent sheet 2 facing the light emitting diode L, a thin film colored layer 4 made of aluminum is formed by, for example, a thin film forming technique such as vapor deposition or sputtering. The colored layer 4 is made of an appropriate thickness of 0.01 to 0.05 μm. Further, on the surface of the colored layer 4, a black character cutout exclusive layer as shown in FIG. 7 having a display item 12 indicating the names of the operation keys 13 and the like of the recording / reproducing function, which are the above-described sub-functions. (3) is printed.
    The basic color of the character cutout exclusive layer 3 is not limited to black only.
    2A and 2B show the display surface 11 of the display device 10A having the above structure seen from the surface of the transparent sheet 2. And on the front panel 21 of the peripheral cabinet 20 around the display surface 11, the display item 22 which shows the operation key 23 of a camera photography function is printed in parallel with the display item 12. As shown in FIG. 2A and 2B correspond to FIGS. 4A and 4B, respectively.
    In the above-described method of FIG. 5, the display item 22 representing the operation key 23 or the like of the camera shooting function as the main function is the display item 12 associated with the recording / playback function as in the display device 10B of FIG. It is printed on the surface of the transparent sheet 2 (opposite side to the light emitting diode L) in a position not overlapping with the light emitting diode.
    In addition, in the present invention as in the known apparatus of the prior art, the transparent sheet 2 may be composed of, for example, a transparent polyethylene resin, a polycarboate resin, an acrylic resin or a vinyl chloride resin.
    Therefore, in the display devices 10A and 10B having the above-described configuration, respectively, when the light emitting diode L is turned off, that is, when the video camera is driven in the camera photographing mode, the display items 12 of the cutout characters are shown in Figs. 2B and 3B. As exemplified in FIG. 2, the advantage is that the mirror layer of the aluminum deposited thin film surface of the colored layer 4 is completely invisible. In addition, the display surface 11 has a color substantially the same as that of the front panel 21 of the cabinet 20, for example, a silver metal color, thereby eliminating the disharmony that exists in the known display device 10 of the prior art. . In addition, since a metallic feeling can be added, a high quality appearance of a video camera equipped with the display device 10A or 10B can be realized.
    On the other hand, when the light emitting diode L is turned on, that is, when the video camera is driven in the recording / reproducing mode, characters such as the operation key 13 are displayed as the display item 12 which can be recognized by the user.
    In the present invention, the urethane resin layer 5 is also formed on the surface of the transparent sheet 2 for the purpose of providing a high quality feeling. In the absence of the urethane resin layer 5, fine lines derived from aluminum deposition of the colored layer 4 were seen on the surface of the transparent sheet 2, so that a low-cost tin plate or the like was deposited on the transparent sheet. It can give you bad sensitivity. For this reason, presence of the urethane resin layer 5 has the effect that this bad sensitivity can be avoided.
    In addition, when the display surface is pressed, a soft feel can be provided, thereby providing a high quality feeling.
    While the present invention has been described with respect to some preferred embodiments, it is apparent to those skilled in the art that the present invention is not limited to the above embodiments and that there are other changes and applications within the scope without departing from the scope of the present invention.
    Accordingly, the scope of the invention should only be determined by the appended claims.
    According to the display device of the present invention, since it appears in a place such as a fairly small video camera (electronic device), it can give a considerably good impression when used for a user, and can display silver and gold metal colors. It is in harmony with the metallic color of the surrounding cabinets and has the effect of giving a higher sense of quality.
