Description

  The present invention relates to various electronic devices having a light emitting unit that presents information by controlling a light emitter such as a navigation device, a microwave detector, and a drive recorder.

  2. Description of the Related Art Conventionally, there are many electronic devices that have a light emitting screen that presents information by controlling a light emitter such as a liquid crystal display or an organic EL display, and that has a front panel larger than the light emitting screen on the front of the light emitting screen. (For example, Patent Document 1). In these electronic devices, in order to conceal an internal electronic board and wiring, a front panel front surface other than a region corresponding to a light emitting screen is generally colored such as black that does not transmit light.

  On the other hand, since the front panel front surface of the area corresponding to the light emitting screen presenting information such as a liquid crystal display or an organic EL display needs to transmit light, it is colored the same color as the front panel front surface other than the area corresponding to the light emitting screen. However, the area is transparent, or the area is pulled out to directly expose the display to the front.

JP 2010-151664 A

  However, since the light-emitting screen does not emit light when the power is turned off and no electronic device is used, such a configuration causes the front panel front surface of the area corresponding to the issuance screen and the front other than the area corresponding to the light-emitting screen. The outline of the border with the front of the panel was clearly visible, and it looked bad and made me feel cheap.

  The present invention solves the above-described conventional problems, and provides an electronic device in which the outline of a region corresponding to a light emitter is less visible from the front surface of the front panel when the electronic device is not used. With the goal.

  In order to solve the above-described conventional problems, an electronic device according to the present invention includes (1) a light emitting unit that presents information by controlling a light emitter, and a coloring unit that is disposed in front of the light emitting unit. In an electronic device comprising a front panel portion having a curved surface, the colored surface of the front panel portion is colored at least within a range where the light of the light emitting portion is projected. And a light-transmitting portion that transmits the light and is formed in a predetermined pattern. With this configuration, the front surface of the front panel unit can be visually less noticeable at the boundary with the region corresponding to the light emitting unit, so that the appearance can be improved and the electronic device can have a high-class feeling. it can. Here, “controlling the light emitter” is not limited to controlling a light emitting element such as an LED, but also controlling a light transmission amount from a backlight such as a liquid crystal. Including.

  (2) The predetermined pattern is a pattern in which the sizes of the plurality of holes are substantially the same, and the intervals in the arrangement direction of the plurality of holes are substantially the same. For example, the predetermined pattern may be a pattern in which a plurality of holes are randomly sized, and a plurality of holes are randomly spaced. A pattern in which the intervals in the arrangement direction of the holes are substantially the same is preferable. In this way, the light from the light-emitting portion is transmitted uniformly, so that it is particularly preferable that the light does not become uneven when viewed from the front surface of the front panel. The intervals in the arrangement direction of the holes are, for example, when the holes are arranged in the up-down direction and the left-right direction, all the intervals in the up-down direction are set to the first predetermined value a and all the intervals in the left-right direction are set to the second predetermined value. The value b is good.

  (3) The predetermined pattern is a lattice pattern in which the plurality of holes are provided in the colored portion at equal intervals. The predetermined pattern may be, for example, a pattern in which a plurality of holes are randomly provided in the colored portion, but by forming a plurality of holes in a lattice pattern provided in the colored portion at equal intervals, the light of the light emitting portion is emitted. Since it permeates uniformly, it is particularly good that it does not become uneven when viewed from the front of the front panel. In particular, when the light emitting portion is formed by a dot matrix display as described later (6), unevenness can be further prevented.

  (4) The hole is circular. The shape of the hole may be any shape such as a polygon such as a triangle, a quadrangle, and a hexagon, and an ellipse, but a circle is preferable. For example, as described later in (9), the light emitting section is formed by a dot matrix display, and as the “determination corresponding to the pixel configuration” in (10), for example, the aspect ratio of the pixels of the dot matrix display is 1: 1. In this case, when the hole is circular, the degree of translucent length and width is the same, and it can be visually recognized without unevenness. For example, the translucent part can be formed by a method such as (6) as compared with other shapes. Easy to do.

  (5) The translucent portion is formed from a plurality of non-colored transparent holes. Therefore, since the light of the light emitting part is transmitted without changing, when the light emitting part emits light with a predetermined color, the predetermined color can be visually recognized from the front panel front as it is.

  (6) The translucent portion is formed by laser processing. Therefore, fine holes can be easily formed by laser processing, and the manufacturing cost can be reduced.

  (7) The coloring of the front panel portion is performed by printing. For printing, for example, a photograph or a picture may be printed in multiple colors, but it is desirable that the color and content of the printing be used so that the light transmitted through the light emitter can be easily seen. Therefore, monochromatic printing is preferable, and a dark color is particularly desirable. Most desirable is black printing. The printed content is most desirably plain, and then a predetermined repeating pattern that is as simple as possible is desirable. The predetermined repetitive pattern is a pattern in which a certain range of patterns appears repeatedly, and examples thereof include a check pattern.

  (8) A logo of the electronic device is printed by the printing. Conventionally, a logo for an electronic device has been printed on the end of the front panel that does not interfere with information presentation. However, in the present invention, it can also be printed on the center of the front panel.

  (9) The light emitting section is formed by a dot matrix display. According to the dot matrix display, the display content of the display can be easily changed to an arbitrary content by controlling the light emitters arranged in the matrix. For example, various information can be easily switched and displayed. Further, by causing only a part of the dot matrix to emit light, it is possible to easily display as if the light emitter exists only in that part. Therefore, it becomes difficult to visually recognize the outline of the region corresponding to the light emitting unit. Note that various displays such as a liquid crystal display and an EL display may be used as the dot matrix display.

  (10) The size and interval of the holes are determined according to the pixel configuration of the dot matrix display. For example, unevenness in the amount of transmitted light can be reduced by determining the size and interval of the holes corresponding to the pixel configuration as shown in the modes (11) to (13) described later.

  (11) As a configuration for determining the size and interval of the holes corresponding to the pixel configuration of the dot matrix display, the pixel size of the dot matrix display and the size of the holes are substantially the same, and the dot matrix The pixel interval of the display is substantially the same as the interval of the holes. In this way, by aligning the positions of the holes in the front panel section with the positions of the pixels in the dot matrix display, most of the light of each pixel is transmitted from the front surface of the front panel, and unevenness in the amount of transmitted light of each pixel. Also disappear.

  (12) As a configuration for determining the size and interval of the holes corresponding to the pixel configuration of the dot matrix display, the size of the holes is made smaller than the size of the pixels of the dot matrix display, and the dot matrix display It is characterized in that the interval between the holes is smaller than the size of the pixel. If (11) is used, optimum transmitted light cannot be obtained unless the positions of the holes in the front panel and the positions of the pixels in the dot matrix display are matched. Therefore, it is better to do (12). In this way, alignment is unnecessary and light of all pixels can be transmitted. In particular, the size of the hole is preferably less than half of the size of the pixel.

  (13) As a configuration for determining the size and interval of the holes corresponding to the pixel configuration of the dot matrix display, the size and interval of the holes are set so that the number of holes is larger than the number of pixels of the dot matrix display. It is characterized by setting. By doing so, information can be presented on a clear screen corresponding to the number of pixels of the dot matrix display.

  (14) The hole is circular and has a diameter in a range of 10 μm to 300 μm. By setting the size within this range, it becomes difficult to recognize the presence of a hole from the front surface of the front panel. Further, for example, holes corresponding to the pixel size of the dot matrix display can be easily formed by the laser processing.

  In the electronic device according to the present invention, since the front surface of the front panel portion is less likely to be visually recognized at the boundary with the region corresponding to the light emitting portion, the appearance can be improved and the electronic device can have a high-class feeling. it can. Further, by forming a plurality of holes in a lattice pattern provided in the colored portion at equal intervals, the light from the light emitting portion is uniformly transmitted, so that unevenness when viewed from the front surface of the front panel can be eliminated.

  In addition, fine holes can be easily formed by laser processing, and the manufacturing cost can be reduced. Furthermore, by determining the size and interval of the holes corresponding to the pixel configuration, it is possible to reduce unevenness in the amount of transmitted light.

  FIG. 1 is a perspective view showing an electronic apparatus according to a first embodiment of the present invention, and FIG. 2 is an explanatory diagram showing a first embodiment of a front panel constituting the present invention. As shown in FIG. 1, the electronic device 10 includes a light emitting unit 2 that presents information by controlling a light emitter, such as a navigation device, a microwave detector, and a drive recorder. Further, a front panel portion 1 having a surface colored by printing is disposed in front of the light emitting portion 2.

  Further, as will be described later, the front panel portion 1 is a colored surface, and is provided in the colored portion and the colored portion in a range 3 where the light of the light emitting portion 2 is projected. Further, a light transmitting portion that transmits light composed of a plurality of holes is formed in a predetermined pattern.

  In addition, the entire surface of the front panel unit 1 is colored, and the light transmitted through the colored portion and the plurality of holes provided in the colored portion is transmitted in a range 4 where the light of the light emitting portion 2 is not projected. It is good also as a structure which forms an optical part with a predetermined pattern, and this is also contained in this invention.

  The light emitting unit 2 is preferably formed by a dot matrix display. According to the dot matrix display, the display content of the display can be easily changed to an arbitrary content by controlling the light emitters arranged in the matrix. For example, various information can be easily switched and displayed. Further, by causing only a part of the dot matrix to emit light, it is possible to easily display as if the light emitter exists only in that part. Therefore, it becomes difficult to visually recognize the outline of the region corresponding to the light emitting unit 2. Examples of the dot matrix display include various displays such as a liquid crystal display and an EL display.

  Moreover, it is suitable to perform the coloring to the front panel part 1 by printing. For printing, for example, a photograph or a picture may be printed in multiple colors, but it is desirable that the color and contents of the print are easy to see the light transmitted when the light emitter of the light emitting unit 2 emits light. Therefore, monochromatic printing is preferable, and a dark color is particularly desirable. Most desirable is black printing. The printed content is most desirably plain, and then a predetermined repeating pattern that is as simple as possible is desirable. The predetermined repetitive pattern is a pattern in which a certain range of patterns appears repeatedly, and examples thereof include a check pattern.

  FIG. 3 is a partially enlarged view of the front panel portion 1 constituting the present invention. As shown in this figure, the front panel portion 1 includes a colored portion 5 that is colored and a translucent portion 7 that transmits light including a plurality of holes 6, 6, and 6 provided in the colored portion 5. It is formed with a predetermined pattern.

  Here, the hole 6 may be an arbitrary shape such as a polygon such as a triangle, a quadrangle, or a hexagon, or an ellipse, but a circle is preferable as shown in FIG. The diameter c of the hole 6 is preferably in the range of 10 μm to 300 μm. By setting the size within this range, it becomes difficult to recognize the presence of a hole from the front surface of the front panel. Further, for example, the holes 6 corresponding to the pixel size of the dot matrix display can be easily formed by laser processing.

  Moreover, it is preferable that the light transmitting portion 7 is formed from a plurality of non-colored transparent holes 6 and 6. With this configuration, the light color of the light emitting unit 2 is transmitted without changing. Therefore, when the light emitting unit 2 emits light with a predetermined color, the predetermined color is visually recognized from the front surface of the front panel unit 1 as it is. can do.

  In addition, as an example of the predetermined pattern formed by the colored portion 5 and the light transmitting portion 7, the sizes c of the plurality of holes 6 and 6 are made substantially the same, and the holes 6 and 6 have the same size. It is preferable that the distances a and b in the arrangement direction are substantially the same. In this way, since the light of the light emitting unit 2 is transmitted uniformly, it is particularly preferable that the light does not become uneven when viewed from the front surface of the front panel unit 1. The intervals in the arrangement direction of the holes 6 and 6 are, for example, when the holes are arranged in the vertical direction and the horizontal direction, all the vertical intervals are a, and all the horizontal intervals are b. .

  Further, as another example of the predetermined pattern formed by the colored portion 5 and the light transmitting portion 7, a lattice pattern (a = b) in which a plurality of holes 6 and 6 are provided in the colored portion 5 at equal intervals. It is also suitable. In this way, since the light of the light emitting unit 2 is transmitted uniformly, it is particularly preferable that the light does not become uneven when viewed from the front surface of the front panel unit 1. In particular, when the light emitting unit 2 is formed of a dot matrix display, it can be made more difficult to be uneven.

  The size c of the plurality of holes 6 and 6 and the intervals a and b may be determined according to the pixel configuration of the dot matrix display. For example, by determining the size c of the hole 6 and the distances a and b corresponding to the pixel configuration as shown in the embodiments 1 to 3 described later, unevenness in the amount of transmitted light is reduced. be able to. When the vertical and horizontal aspect ratios of the pixels of the dot matrix display are 1: 1, if the holes 6 are circular, the vertical and horizontal light transmission levels are the same, so that they can be visually recognized without unevenness.

  (Embodiment 1) The pixel size of the dot matrix display and the size c of the hole 6 are made substantially the same, and the pixel interval of the dot matrix display and the intervals a and b of the hole 6 are made substantially the same. In this way, by matching the position of the hole 6 of the front panel unit 1 and the position of the pixel of the dot matrix display, much of the light of each pixel is transmitted from the front surface of the front panel unit 1, and the light of each pixel is transmitted. The unevenness of the transmission amount is also eliminated.

  (Embodiment 2) The size c of the hole 6 is made smaller than the size of the pixel of the dot matrix display, and the distances a and b of the hole 6 are made smaller than the size of the pixel of the dot matrix display. According to the first embodiment, optimal transmitted light cannot be obtained unless the positions of the holes 6 of the front panel unit 1 and the positions of the pixels of the dot matrix display are matched. Therefore, it may be performed as in the second embodiment. In this way, alignment is unnecessary and light of all pixels can be transmitted. In particular, the size c of the hole 6 is preferably less than half the size of the pixel.

  (Embodiment 3) Size c of holes 6 and intervals a and b are set so that the number of holes 6 is larger than the number of pixels of a dot matrix display. By doing so, information can be presented on a clear screen corresponding to the number of pixels of the dot matrix display.

  FIG. 4 is an explanatory view showing a method of manufacturing the front panel portion 1 constituting the present invention. The manufacturing method of the front panel part 1 is demonstrated using this figure. First, in the front panel portion 1, a colored portion 5 colored by printing is formed on the upper surface of a transparent plate 8 that transmits light. The coloring unit 5 is irradiated with laser beams 11 and 11 by a laser device 9. Then, the colored surface of the colored portion 5 irradiated with the laser beam 11 is heated and sublimated, whereby the hole 6 is formed. Thus, by manufacturing the translucent portion 7 of the front panel portion 1 by laser processing, the fine holes 6 can be easily formed, and the manufacturing cost can be reduced.

  FIG. 5A shows a state where the front panel unit 1 constituting the present invention is viewed when the light emitting unit 2 emits light, and FIG. 5B shows a case where the light emitting unit 2 does not emit light. The example of the state which looked at the front panel part 1 which comprises this invention is shown. FIG. 6 shows a state in which the conventional front panel portion is viewed when the light emitting portion is not emitting light.

  As shown in FIG. 5A, when the light emitting unit 2 emits light, light is transmitted from the light transmitting unit 7 formed by the plurality of holes 6 and 6 formed in the front panel unit 1. Thus, the displayed contents can be clearly recognized. On the other hand, when the light emitting unit 2 is not emitting light, no light is transmitted from the light transmitting unit 7 formed by the plurality of holes 6 and 6 formed in the front panel unit 1. The colored state of the colored portion 5 is visually recognized as it is. Therefore, as shown in FIG. 5B, if the colored portion 7 in which the logo related to the electronic device is printed in white is formed on the black background, the logo can be clearly recognized and the light emitting portion 2 can be visually recognized. It becomes difficult to visually recognize the boundary with the corresponding area. On the other hand, in the conventional front panel unit shown in FIG. 6, since the region corresponding to the light emitting unit is transparent, the boundary is clearly visible when the power is turned off.
