Detailed Description
Hereinafter, a display device according to an embodiment of the present invention will be described in detail with reference to the drawings. The present invention is not limited to the embodiments.
Fig. 1 is a perspective view of a display device according to embodiment 1 of the present invention. Fig. 2 is an exploded perspective view of the display device according to embodiment 1. The display device 1 is, for example, a servo amplifier. The display device 1 includes a housing 2, a substrate 3, and a display surface sheet 4. The housing 2 is a box body that accommodates the substrate 3 therein. One of the outer surfaces of the housing 2 serves as a display surface 21. In embodiment 1, the display surface 21 has a rectangular shape. In the following description, a direction along the longitudinal direction of the display surface 21 is referred to as a vertical direction, and a direction along the short-side direction of the display surface is referred to as a width direction. In addition, a direction perpendicular to the vertical direction and the width direction is a depth direction. Note that the concept of directions such as the vertical direction, the width direction, and the depth direction is introduced for convenience of description, and the directions thereof also change according to the posture of the display device 1.
Fig. 3 is an enlarged partial oblique view of a portion a shown in fig. 2. A plurality of holes 22 penetrating the outside and the inside of the housing are formed in the display surface 21. In embodiment 1, 7 holes 22 are formed. The 7 holes 22 are formed in a configuration capable of 7-segment display by light transmitted through the holes 22.
Returning to fig. 2, the structure of the substrate 3 will be described. The substrate 3 has a 1 st mounting surface 31 on which electronic components not shown are mounted. The 1 st mounting surface 31 of the substrate 3 is a quadrangular shape. The substrate 3 is accommodated in the housing 2 with the 1 st mounting surface 31 perpendicular to the display surface 21 of the housing 2. The substrate 3 is disposed at a position overlapping with a region where the plurality of holes 22 are formed, when viewed in the depth direction. The back side of the 1 st mounting surface 31 is the 2 nd mounting surface 32.
Fig. 4 is an enlarged partial oblique view of a portion B shown in fig. 2. A plurality of 1 st light-emitting elements 5 are mounted on the 1 st mounting surface 31 of the substrate 3. The 1 st light emitting elements 5 are arranged in upper and lower rows along a side closest to the display surface 21 among the 1 st mounting surface 31. Each of the 1 st light-emitting elements 5 is disposed at a position overlapping any one of the plurality of holes 22 in the vertical direction when viewed in the depth direction.
The 1 st light emitting elements 5 are mounted on the 1 st mounting surface 31 in such directions as to emit light toward the holes 22. The 1 st light Emitting element 5 is, for example, a right angle type led (light Emitting diode).
Fig. 5 is an enlarged partial oblique view of a portion B shown in fig. 2, and shows a 2 nd mounting surface of the substrate. A plurality of 2 nd light emitting elements 6 are mounted on the 2 nd mounting surface 32 of the substrate 3. The plurality of 2 nd light emitting elements 6 are arranged in the upper and lower rows along the side closest to the display surface 21 among the 2 nd mounting surface 32. Each of the plurality of 2 nd light emitting elements 6 is disposed at a position overlapping any one of the plurality of holes 22 in the arrangement direction of the plurality of 2 nd light emitting elements 6.
The plurality of 2 nd light emitting elements 6 are mounted on the 2 nd mounting surface 32 in such a direction that they emit light toward the holes 22. The 2 nd light emitting element 6 is, for example, a right angle type LED.
Fig. 6 is an enlarged partial oblique view of a portion C shown in fig. 2. The display surface sheet 4 is a sheet-like member that covers the display surface 21 of the housing 2. The display surface sheet 4 has a plurality of light-transmitting portions 41 formed in a portion overlapping with the holes 22 formed in the display surface 21 and transmitting light therethrough. The transmission portion 41 is formed of a transparent or translucent material. The display surface sheet 4 does not transmit light in the region other than the transmission portion 41. For example, the entire display surface sheet 4 may be formed of a transparent or translucent material, and the regions other than the transmission portion 41 may be coated so as not to transmit light in the regions other than the transmission portion 41. The plurality of transmission portions 41 are provided in an arrangement capable of 7-segment display, similarly to the arrangement of the plurality of holes 22. In the following description, the transmissive portion 41 having a shape extending in the vertical direction among the plurality of transmissive portions 41 is referred to as a 1 st transmissive portion 41a, and the transmissive portion 41 having a shape extending in the width direction is referred to as a 2 nd transmissive portion 41 b. In the display surface sheet 4, 41 st transmission portions 41a and 32 nd transmission portions 42b are formed for 7-segment display.
Fig. 7 is a front view of the display device according to embodiment 1 as viewed from the display surface side. Fig. 8 is a sagittal cross-sectional view taken along line VIII-VIII shown in fig. 7. Fig. 9 is a sagittal sectional view taken along line IX-IX shown in fig. 8.
On a rear surface 27 of the housing 2, which is a rear surface of the display surface 21, a protruding portion 7 protruding in the depth direction is formed in a region where the hole 22 is formed. The convex portion 7 has a 1 st wall 23, a 2 nd wall 24, and a connecting wall 26.
Fig. 10 is a view of the housing in embodiment 1 as viewed from the back of the display surface, and is a partially enlarged view of a portion where the convex portion is formed. Fig. 11 is a perspective view of the housing in embodiment 1 as viewed from the back of the display surface, and is a partially enlarged perspective view of a portion where the convex portion is formed.
The 1 st wall 23 extends from the periphery of the hole 22 toward the 1 st light emitting element 5. The 1 st wall 23 covers a region of a part of the 1 st mounting surface 31 of the substrate. The 1 st wall 23 separates the plurality of holes 22 from each other on the back of the display surface 21. As shown in fig. 9, the 1 st wall 23 forms a plurality of 1 st accommodation chambers 28 that partition the plurality of 1 st light-emitting elements 5 from each other when viewed from the rear surface 27 side. In embodiment 1, 1 st light-emitting element 5 is provided in 1 st housing chamber 28 so as to overlap with each other. 5 1 st light emitting elements 5 are mounted on the 1 st mounting surface 31. That is, 5 first accommodation chambers 28 are provided on the back surface of the display surface 21.
The 2 nd wall 24 extends from the periphery of the aperture 22 towards the 2 nd light emitting element 6. The 2 nd wall 24 covers a region of a part of the 2 nd mounting surface 32 of the substrate. The 2 nd wall 24 separates the plurality of holes 22 from each other on the back of the display surface 21. As shown in fig. 9, the 2 nd wall 24 forms a plurality of 2 nd accommodating chambers 29 that partition the plurality of 2 nd light emitting elements 6 from each other when viewed from the rear surface 27 side. In embodiment 1, 1 nd light emitting element 6 is provided in 1 nd 2 nd housing chamber 29 so as to overlap each other. On the 2 nd mounting surface 32, 5 2 nd light emitting elements 6 are mounted. That is, 5 2 nd accommodation chambers 29 are provided on the back surface of the display surface 21.
The connecting wall 26 connects the 1 st wall 23 and the 2 nd wall 24. The connecting wall 26 projects from the back surface 27 by a smaller amount than the 1 st wall 23 and the 2 nd wall 24. Thus, a gap 25 is formed between the 1 st wall 23 and the 2 nd wall 24.
The substrate 3 is positioned by inserting the end of the substrate 3 into the gap 25. That is, the gap 25 between the 1 st wall 23 and the 2 nd wall 24 functions as a positioning portion for positioning the substrate 3 in the width direction. The inserted substrate 3 abuts against the connecting wall 26. That is, the connecting wall 26 functions as a positioning portion for positioning the substrate 3 in the depth direction.
In the display device 1 according to embodiment 1, the 1 st light-emitting element 5 emits light toward the hole 22, and the 2 nd light-emitting element 6 emits light toward the hole 22. Therefore, even if the substrate 3 is accommodated in the housing 2 with the 1 st mounting surface 31 being perpendicular to the display surface 21 of the housing 2, the light emitted from the 1 st light-emitting element 5 and the 2 nd light-emitting element 6 can be directed toward the hole 22 provided in the display surface 21.
Therefore, the light emitted from the 1 st light emitting element 5 and the 2 nd light emitting element 6 can be transmitted through the hole 22 and the transmission portion 41 of the display surface sheet 4, and 7-segment display can be performed in the display device 1. At this time, the light-emitting elements of the 1 st light-emitting element 5 and the 2 nd light-emitting element 6 emit light, so that the desired transmissive portion 41 appears to emit light, whereby the display device 1 can display numerals of 0 to 9, for example. In the following description, the case where the transmissive portion 41 appears to emit light for displaying a numeral or the like is simply referred to as the case where the transmissive portion 41 emits light, and the case where the transmissive portion 41 does not appear to emit light is simply referred to as the case where the transmissive portion 41 does not emit light.
In addition, since the 1 st mounting surface 31 on which electronic components other than the 1 st light-emitting element 5 are mounted is not parallel to the display surface 21 but perpendicular to the display surface 21, the display surface 21 can be formed smaller than the 1 st mounting surface 31. In addition, even when the display surface 21 is reduced in size, a region for mounting other electronic components can be secured on the 1 st mounting surface 31 which extends in the depth direction.
Further, since the plurality of 1 st light emitting elements 5 are housed in the 1 st housing chamber 28 and the plurality of 2 nd light emitting elements 6 are housed in the 2 nd housing chamber 29, light from the 1 st light emitting elements 5 and the 2 nd light emitting elements 6 is less likely to leak into the other housing chambers. Therefore, light is not easily leaked to the transmission portion 41 other than the transmission portion 41 facing the 1 st and 2 nd housing chambers 28 and 29 housing the 1 st and 2 nd light emitting elements 5 and 6 emitting light. Therefore, the difference between the light-emitting transmissive portion 41 and the non-light-emitting transmissive portion 41 becomes clear, and the display on the display surface 21 can be made clearer. Further, since the substrate 3 inserted into the gap 25 between the 1 st wall 23 and the 2 nd wall 24 also serves as a part of the wall surrounding the 1 st accommodation chamber 28 and the 2 nd accommodation chamber 29, light leakage to the transmission portion 41 where no light is emitted is also suppressed by the substrate 3.
Further, since the substrate 3 can be positioned by inserting the substrate 3 into the gap 25 provided between the 1 st wall 23 and the 2 nd wall 24, it is possible to prevent the 1 st light emitting element 5 and the 2 nd light emitting element 6 from being displaced, and light from not sufficiently reaching the transmission portion 41 and becoming unclear.
Further, since the substrate 3 can be positioned only by inserting the substrate 3 into the gap 25, it is not necessary to use a jig or the like for positioning the substrate 3. Since the substrate 3 can be easily positioned without using a jig or the like, the assembling property of the display device 1 can be improved.
The transmissive portion 41 of the display surface sheet 4 may be configured to diffuse light. For example, the incident surface of the transmission portion 41 may be formed of a rough surface to diffuse light. The transmission section 41 may be formed of a material that easily diffuses light. This allows the entire transmissive portion 41 to emit light uniformly, thereby realizing an easily observable display with suppressed luminance unevenness.
The opposite surface of the display surface sheet 4 to the surface facing the display surface 21 of the housing 2 may be a half mirror. This allows the non-light-emitting transmissive portion 41 to be visually recognized similarly to the other regions, and the non-light-emitting transmissive portion 41 does not appear to be provided. On the other hand, when the 1 st light emitting element 5 or the 2 nd light emitting element 6 is caused to emit light, the half mirror is transmitted by the light, and the transmitting portion 41 emits light. Therefore, the difference in appearance between when the light is emitted and when the light is not emitted can be increased.
In embodiment 1, the projection 7 is provided on the back surface 27 of the housing 2, but the display device 1 may be provided without the projection 7. In the case where the convex portion 7 is not provided, although light leakage to the transmission portion 41 which does not emit light is slightly generated without the 1 st wall 23 and the 2 nd wall 24, or positioning of the substrate 3 is slightly complicated without the gap 25, if the 1 st mounting surface 31 is perpendicular to the display surface 21, an effect of making the display surface 21 smaller than the 1 st mounting surface 31 can be obtained. When the projection 7 is not provided, a projection may be formed on one of the substrate 3 and the back surface 27 of the housing 2, a recess into which the projection is fitted may be formed on the other, and the projection may be fitted into the recess to position the substrate 3.
In embodiment 1, an example has been described in which the transmission portion 41 is caused to emit light and a numeral can be displayed by 7-segment display, but the shape and arrangement of the transmission portion 41 are not limited to this, and the transmission portion 41 may be caused to emit light and a figure or a character can be displayed.
Fig. 12 is a perspective view of the 1 st wall, the 2 nd wall, and the substrate in the display device according to modification 1 of embodiment 1, and is a view showing a state before the substrate is inserted into the gap. Fig. 13 is a perspective view of the 1 st wall, the 2 nd wall, and the substrate according to modification 1 of embodiment 1, and is a view of a state where the substrate is inserted into the gap.
In modification 1, a notch 33 is formed in a region of the substrate 3 that is 1 side and inserted into the gap 25. When the substrate 3 is inserted into the gap 25, the connecting wall 26 of the projection 7 is fitted into the notch 33. In addition to the positioning of the substrate 3 in the short direction by inserting the substrate 3 into the gap 25, the positioning of the substrate 3 in the vertical direction by fitting the connecting wall 26 into the notch 33 is also performed. That is, the convex portion 7 is inserted into the substrate 3, thereby more accurately positioning the substrate 3.
Fig. 14 is a partially enlarged view of the substrate in which the mounting portion of the 1 st light emitting element in the display device according to modification 2 of embodiment 1 is enlarged. In modification 2, 21 st light emitting elements 5 among the 5 1 st light emitting elements 5 mounted on the 1 st mounting surface 31 are different in distance from the other 1 st light emitting elements 5 from the display surface 21.
Specifically, the distance D1 between the 1 st light-emitting element 5 emitting light toward the 1 st transmissive section 41a of the plurality of transmissive sections 41 formed in the display surface sheet 4 and the display surface 21 is larger than the distance D2 between the 1 st light-emitting element 5 emitting light toward the 2 nd transmissive section 41b of the plurality of transmissive sections 41 extending in the width direction and the display surface 21.
Fig. 15 is a cross-sectional view of the display device according to modification 2, which corresponds to a sagittal cross-sectional view taken along line VIII-VIII shown in fig. 7. When the 1 st light-emitting element 5 and the transmission portion 41 are viewed in the vertical direction, an angle formed by a line perpendicular to the rear surface 27 of the display surface 21 and a line along the incident direction of light from the 1 st light-emitting element 5 to the transmission portion 41 is defined as an incident angle θ. As the incident angle approaches the obtuse angle, the brightness of the transmission portion 41 through which the light from the 1 st light-emitting element 5 is transmitted tends to be uneven.
As shown in fig. 15, the distance D1 > the distance D2 allows the incident angle θ 1 > the incident angle θ 2. This makes it possible to set the incident angle θ 2 to a sharper angle, suppress unevenness in brightness of the transmissive portion 41, and make display easier to observe.
Fig. 16 is a sagittal sectional view taken along line XVI-XVI shown in fig. 7. Fig. 16 is a view showing a 2 nd transmissive part 41b partially cut in a shape extending in the width direction.
As shown in fig. 14, the distance D2 between the 1 st light-emitting element 5 emitting light toward the 2 nd transmissive part 41b and the display surface 21 is smaller than the distance D1 between the 1 st light-emitting element 5 emitting light toward the 1 st transmissive part 41a and the display surface 21. However, since the distance D4 between the incident position of the light from the 1 st light emitting element 5 to the 2 nd transmissive portion 41b and the short side direction of the 1 st light emitting element 5 shown in fig. 16 is smaller than the distance D3 between the incident position of the light from the 1 st light emitting element 5 to the 1 st transmissive portion 41a and the width direction of the 1 st light emitting element 5 shown in fig. 15, the incident angle θ 3 is less likely to be an obtuse angle even if the distance D2 is smaller than the distance D1. Therefore, even if the 1 st light emitting element 5 emitting light toward the 2 nd transmission part 41b is provided at a position closer to the display surface 21 than the 1 st light emitting element 5 emitting light toward the 1 st transmission part 41a, unevenness in luminance of the 2 nd transmission part 41b can be suppressed. By being closer to the display surface 21 than the 1 st light-emitting element 5, sufficient luminance can be easily obtained by the 2 nd transmission part 41b even if the light amount of the 1 st light-emitting element 5 is suppressed.
For the same reason as that of the 1 st light emitting element 5, the 2 nd light emitting element 6 emitting light toward the 1 st transmission part 41a is provided at a position farther from the display surface 21 than the 2 nd light emitting element 6 emitting light toward the 2 nd transmission part 41 b. More specifically, the 1 st light-emitting element 5 and the 2 nd light-emitting element 6 are disposed at symmetrical positions with the substrate 3 interposed therebetween.
The configurations described in the above embodiments are only examples of the contents of the present invention, and may be combined with other known techniques, and some of the configurations may be omitted or modified without departing from the scope of the present invention.
