Description

  The present invention relates to a display device used for electronic devices and the like, and a display device including the display device.

  2. Description of the Related Art Conventionally, a segment display (7-segment display) or dot capable of displaying characters, symbols, pictures, and the like, such as Arabic numerals, by arranging a plurality of segment regions that function as a display unit and combining segment regions that emit light with LEDs or the like. Matrix displays are known. As an example, the LED is mounted on a printed circuit board, and a light guide hole is formed at each position corresponding to the LED among the covers arranged so as to cover the LED, and the light from the LED is diffused on the surface of the cover. There is a segment display to which a diffusion sheet is attached.

  In the case of a segment display device in which LEDs are arranged directly below such light guide holes, it is necessary to set the thickness of the cover to a certain value or more in order to obtain an appropriate diffusion effect by the diffusion sheet. That is, when a cover having a thickness smaller than a certain value is applied, light from each LED cannot be appropriately diffused, and uniformity of luminance in each light emitting segment region cannot be secured. Therefore, in a mode in which the segment display section constituted by the light guide holes and the diffusion sheet is disposed at a position facing the LED, it is not possible to achieve both the reduction in thickness of the entire segment display and the uniformity of luminance in each light emitting segment region. .

  Patent Literature 1 discloses that seven LEDs arranged on a printed circuit board correspond to each side of a frame-shaped portion in which one side of two rectangular frame-shaped portions is shared so as to represent an Arabic numeral 8. A seven-segment display capable of illuminating the three display units, seven light-transmitting light-transmitting units arranged opposite to the printed circuit board corresponding to the display units, and a light-shielding frame arranged opposite to the printed circuit board; The light-shielding frame includes a housing section having a light guide section arrangement section in which the light guide sections are individually arranged and an LED arrangement section capable of accommodating the LED, which are continuous with the light guide section. There is disclosed a configuration in which one provided is applied and LEDs are arranged inside or outside a frame-shaped portion.

  According to the document, "Since the LED arrangement portion is provided inside or outside the frame-shaped portion, the LED can be arranged at a position deviated from directly below the display portion (omitted), and the light guide portion is configured to be thin. In addition, since the distance between the LED and the display unit can be ensured, and the unevenness in brightness of the display unit due to direct light from the LED can be reduced, uniformity of luminance in the display unit can be ensured (omitted). It is possible to reduce the thickness of the entire device while ensuring the uniformity of the luminance in each display unit. "

  By the way, in the conventional segment display including the configuration described in Patent Document 1, the lit segment display can be visually recognized from one surface side (front side) of the segment display, that is, from the display unit side. It is not at all assumed that it is visible from the opposite side (back side). This can be easily understood from the fact that a substrate having substantially the same size as the light-shielding frame is entirely disposed behind the display unit.

  Also, in the conventional segment display, since the color lit on the display unit is determined by the emission color of the LED mounted on the substrate, for example, a pattern or a pattern is reflected (mixed) in the color (color lit). It is impossible or extremely difficult to increase the variation of the expression.

  Such a problem is not limited to a segment display, but is also a problem common to a matrix display or a dot matrix display that can display characters, symbols, pictures, and the like by arranging a plurality of display units in rows and columns.

  The present invention has been made in view of such a point, and a main object is to provide a display device that can be visually recognized from both directions of a front surface and a back surface while reducing the thickness, and such a display device. It is an object of the present invention to provide a display device which can display not only luminescent colors but also special contents such as patterns on a display unit simultaneously with the luminescent colors.

  That is, the present invention relates to a display device capable of displaying a plurality of display units by individually lighting the display units. The display device according to the present invention includes a substrate on which a light emitting source is mounted, and a transparent or translucent resin mixed with a diffusing material, and a plurality of display units capable of surface light emission. A display, and a light-shielding cover having a light-shielding portion that defines a surface light-emitting area of each display unit in the transparent display, and a unit is formed by laminating a substrate, a transparent display, and a light-shielding cover in this order. As the substrate, a substrate in which a light emitting source is mounted at a position that does not overlap with the display unit in the stacking direction and that is close to each display unit in a unitized state is applied to each display unit in the stacking direction of the substrate. An opening is formed in an overlapping portion.

  As the light emitting source, a light emitting diode (LED) can be mentioned, but in the present invention, a light emitting source other than the LED can be applied. The display device according to the present invention is a unit in which a substrate, a transparent display, and a light-shielding cover are unitized in a stacked configuration in this order, in other words, a unit in which a transparent display unit is disposed between the light-shielding cover and the substrate.

In particular, in the case of the display device according to the present invention, the first layout condition that the light emitting source mounted on the substrate does not overlap (do not face) each display unit of the transparent display body in the stacking direction, and the position close to each display unit Based on a configuration that satisfies the second layout condition of disposing a light emitting source in the display device, it is possible to reduce the overall thickness of the display as compared with a configuration in which the light emitting source and the display unit face each other in the stacking direction. Furthermore, since the display device according to the present invention has openings formed in portions of the substrate that overlap each display portion in the stacking direction, the illuminated display can be visually recognized from the display portion side (front side) of the display device. Also, the illuminated display can be visually recognized from the substrate side (the back surface side) of the display.

  Furthermore, in the display according to the present invention, by using a transparent or translucent resin display unit, the rear side (the other side) of the display unit can be seen through, which is not possible with conventional displays. Possible use forms, for example, disposing a display unit different from the display unit according to the present invention at the back of the display unit, or arranging an appropriate image or the like on the display unit of the display unit according to the present invention. It is possible to use such a method of displaying them (display contents and images of the display device arranged at the back of the display device), and to increase and diversify the display patterns.

  If the display device according to the present invention is such that the surface on the substrate side is set as a mirror surface in the stacking direction among the display portions, the illuminated display with a sense of depth by reflecting surface light of the display portion on the mirror surface. become. By performing the mirror processing, it is possible to set the mirror surface. Further, by adopting a configuration in which the mirror is arranged between each display unit and the substrate with the mirror surface facing each display unit, a display device having the same operation and effect can be realized.

In addition, by repeating the surface light emission of the display unit on the mirror surface or the mirror and the half mirror surface, an illuminated display with a more sense of depth is provided. Here, as a specific mode for setting the half mirror surface, a mode in which a half mirror processing process is performed or a deposition process is performed can be given. In addition, by adopting a configuration in which a half mirror is arranged between each display unit and the light-shielding cover, it is possible to realize a display device having the same operation and effect.

  In the display device according to the present invention, when a printed film on which an arbitrary pattern is printed at least at a portion corresponding to each display unit is disposed at a position farther from the substrate than the transparent display body in the stacking direction, the display of the display unit is displayed. Printed film patterns can be superimposed on the contents, increasing the variety of expressions. Further, by adopting a configuration in which a print film on which an arbitrary pattern is printed at least at a portion corresponding to each display unit is disposed at a position farther from the display unit than the substrate in the stacking direction, the same operation and effect can be obtained. be able to.

  The display according to the present invention has a configuration in which a back cover is provided on the back surface side of the display, that is, a display including a back cover disposed at a position sandwiching the transparent display body and the substrate between the display and the light-shielding cover. Is also included. Such a display can improve impact resistance and design compared to a configuration without a back cover, and in particular, in a mode in which a half mirror, a mirror, or a print film is not provided, By forming a back cover opening in a portion of the back cover facing each display in the stacking direction, the illuminated display of each display can be displayed on the display unit side (front side) and the back cover side (back side) of the display. Side) can be secured.

The display according to the present invention can be used as a segment display when an elongated segment display section is applied as each display section, and a dot matrix when a circular or spherical dot display section is applied as a display section. Can be used as a display.
In addition, the display device according to the present invention mainly includes the display having the above-described configuration, and further displays an arbitrary symbol on the back surface side of the display by a second light source different from the light source of the display. It is characterized in that a possible second display is arranged.
