Description

  The present invention relates to a display panel that notifies the operating state of an apparatus by light emitted from a light emitter, and an electric device provided with the display panel.

  Generally, a display panel is provided on a front plate of a casing constituting an electric device. The display panel has a light emitting portion that shines in red, green, or the like, for example, so that the user can easily recognize the operation state of the device.

  In Japanese Patent Laid-Open No. 10-160521, uniform and bright transmitted illumination can be obtained without being affected by the instrument body, and color and design changes that are completely different between daytime and nighttime can be obtained. An instrument display device including a display panel provided is disclosed.

  Japanese Unexamined Patent Application Publication No. 2005-3391 discloses a vehicle display device that can increase the light emission brightness of a dial without enlarging the size of the light guide.

  Furthermore, Japanese Patent Application Laid-Open No. 7-282677 discloses an illuminating panel switch having a thin operation panel with small light unevenness and illuminated over a wide range.

  Japanese Patent Application Laid-Open No. 2010-67551 discloses that the number of component parts can be reduced to reduce the thickness and weight, and further, the assembly man-hours of the component parts can be reduced to assemble the component parts. There is disclosed a backlight device that can easily reduce the cost of components and the assembly cost.

  Endoscopes used in the medical field or the like include a light source device, a video processor, and the like as electrical devices that are external devices. A display panel is also provided on the front plate of the casing constituting these devices.

  In display panels of electrical equipment used in dark spaces such as endoscope rooms, the display unit should be illuminated with a wide variety of colors, such as red and yellow-green, so that the user can instantly recognize the operating state. The relationship between the operation content and the display color of the display panel is defined by the standard.

  For display panels of electrical equipment used in dark spaces, when the panel surface (also referred to as the front of the panel) is made flat, the entire surface of the display panel shines when strong light strikes the front of the panel from the front. There is. Then, it may be difficult to recognize the display characters and numbers on the panel and confirm the operation state.

For this reason, in an electric device used in a dark space, for example, the surface side of the display substrate of the electrical component is formed into a convex curved surface with a radius of 1000 mm or the like, and the panel is attached to the convex curved surface to constitute a display panel. According to the display panel of this configuration, when strong light hits the front of the panel from the front, the highlight line appears on a part of the surface of the display panel, but the invisibility due to the entire surface of the display panel shining is eliminated Is done.
However, when adhering a display panel having a display substrate of an electrical component to a front plate, the entire surface is made to be an adhesive surface by making the substrate hard by forming a light-transmitting region of a predetermined shape on the substrate. There is a risk that the bonding area will be insufficient.

  Further, when the substrate is made of a base material that is difficult to bend, if a convex curved surface having a radius of 1000 mm or the like is formed on the surface side, the entire surface cannot be made an adhesive surface, and the adhesive area may be insufficient.

  In addition, when transported by an aircraft or the like, the electrical equipment is exposed to an environment under high temperature and high humidity, an environment in which the temperature changes greatly, or an environment in which the humidity changes greatly. Then, there is a possibility that the adhesive force of the adhesive that bonds the display panel to the front plate is reduced at a stretch.

  For this reason, various measures are taken to form a thin display panel so as to suppress the force with which the display panel is peeled off from the front plate. However, as a result, the cost is increased, the number of work steps is increased, and there is a possibility that the display panel has to be difficult to check the operation state.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide an inexpensive display panel excellent in visibility and an electric device provided with such a display panel on a front plate.

  FIG. 5A is a diagram for explaining the relationship between the illumination plate 22 and the flexible substrate 31, and the opening 28 m of the recess 28 is set larger than the outer diameter of the LED illumination 36 by a predetermined dimension. The depth dimension of the recess 28 is set to a predetermined dimension.

Specifically, the vertical and horizontal dimensions of the LED illumination 36 are 1.6 mm × 0.8 mm, for example, the diameter dimension of the opening 28 m of the recess 28 is φ3 mm, and the depth dimension of the recess 28 is 3 mm.
In addition, the recessed part 28 is a reflection part which serves as an accommodating part .

Emitted.

The print sheet 32 will be described with reference to FIGS. 3, 6, and 7.
The printing sheet 32 shown in FIGS. 3 and 6 is a transparent plate having a flexible thickness dimension of, for example, 0.5 mm. The print sheet 32 is a display member. The print sheet 32 has a flat surface 32a and another flat surface 32b that is the opposite surface of the flat surface 32a. The one plane 32 a is disposed to face the second surface 31 b of the flexible substrate 31.

In this embodiment, the one plane 32a shown in FIG. 6 is a silk-printed surface, for example. On the other hand, the other plane 32b shown in FIG. 3 is an operation surface. A sheet-side embossing section 38 and an operation display section 39 are provided on the operation surface.
The sheet-side embossed portion 38 constitutes various switches. The operation display unit 39 is provided in the vicinity of the sheet-side embossing unit 38. In the operation display section 39, switch operation contents, switch names, operation states, and the like are described.

  The one plane 32a shown in FIG. 6 is configured to be opaque except for the light transmission part 32e. The light transmission part 32 e is a light emitting part that emits light by the light transmitted through the flexible substrate 31. In other words, an opaque portion 32n, a plurality of light transmitting portions 32e, and a sheet-side embossed portion 38, which are indicated by oblique lines that are non-transmissive surfaces, are provided on one plane 32a of the print sheet 32.

  The opaque part 32n is colored with a predetermined color. The opaque portion 32n is a light shielding portion, and blocks orange transmitted light that has passed through the flexible substrate 31 from entering the print sheet 32 from the one plane 32a side.

  Further, the opaque portion 32n is provided with a double-sided tape affixing region 33B for a printing sheet indicated by a two-dot chain line. A double-sided tape having a glue surface having a predetermined adhesive strength is applied to the double-sided tape application region 33B for the printing sheet. The double-sided tape is also affixed to a predetermined location in the affixing area 33B.

The light transmission part 32e is a transparent part other than the opaque part 32n and the sheet-side embossed part 38 provided on one plane. The light transmission part 32e is formed in a predetermined shape, for example, a circle.
The light transmission part 32e is configured so that the orange transmitted light transmitted through the flexible substrate 31 having a natural color of orange is colored in a desired color by passing from the one plane 32a side to the other plane 32b side. .

  Specifically, when it is desired to color the light transmitting portion 32e with, for example, orange light that is transmitted light, the transparent sheet is maintained in a transparent state without being colored.

  On the other hand, when the light transmitting portion 32e is colored with, for example, green, a predetermined color is colored on the transparent plane 32a shown in FIG. 7 and the complementary color filter portion 32f is provided in the light transmitting portion 32e.

Specifically, the one color plane 32a of the light transmission portion 32e is colored with the first complementary color 5BG that changes the orange color 5YR to the green color 5GY with reference to, for example, the Munsell color system shown in FIG. 32f is provided.
When the light transmitting portion 32e is colored with, for example, reddish purple 5RP, referring to the Munsell color system shown in FIG. 8, the orange 5YR is changed to reddish purple 5RP on one plane 32a of the light transmitting portion 32e. The complementary color filter portion 32f is provided by coloring the second complementary color 5PB.
It should be noted that by finely adjusting the color of the complementary color filter unit 32f while adding the color to the complementary color, it is possible to meet sensory demands such as a slightly darker green color.

  As a result, when the orange transmitted light that has passed through the flexible substrate 31 passes through the transparent light transmitting portion 32e, the light transmitting portion 32e emits orange light.

On the other hand, when the orange transmitted light passes through the light transmitting portion 32e provided with the complementary color filter portion 32f having the first complementary color, the light transmitting portion 32e emits green light.

  The orange transmitted light passes through the light transmitting part 32e provided with the complementary color filter portion 32f having the second complementary color, so that the light transmitting part 32e emits reddish purple.

  As described above, for example, white light is emitted from the LED illumination 36, and the light transmitting portion 32e is colored with a desired color with respect to the orange transmitted light transmitted through the flexible substrate 31, so that each light transmitting portion 32e is desired. A complementary color filter unit 32f corresponding to the color is provided.

  According to this configuration, the light transmission part 32e is easily desired as compared with the case where the light transmission part 32e is transparent and the color is set for each LED illumination 36 and the light transmission part 32e is colored with a desired color. Color can be developed.

  Moreover, since there is only one type of LED illumination 36, the number of components can be reduced and workability can be improved as compared with the case where a plurality of types of LEDs with colors set are used.

  Although the LED illumination 36 is white light, the LED illumination may be capable of changing the color of the emitted light.

Here, affixing to the affixing surface 27 of the display panel 30 will be described.
In this embodiment, the operator first applies a double-sided tape (not shown) provided in advance on one plane 32a of the printing sheet 32 to the second surface 31b of the flexible substrate 31 as indicated by an arrow Y3A in FIG. The display panel 30 is configured by pasting.

  As a result, the filter portion 32 f provided on the one plane 32 a of the print sheet 32 is disposed so as to close the opening 28 m of the recess 28 with the flexible substrate 31 interposed therebetween.

  As a result, the light transmission part 32e faces the back surface of the LED illumination 36 mounted on the first surface 31a of the flexible substrate 31.

  Next, the operator applies a double-sided tape (not shown) provided in advance on the first surface 31a of the flexible substrate 31 of the display panel 30 to the affixing surface 27 of the front plate 22 as shown by an arrow Y3B in FIG. paste.

As a result, as shown in FIG. 9, the display panel 30 is pasted on the convex curved pasting surface 27 of the front plate 22 constituting the casing 21, and the CCU 3 shown in FIG. 1 is constructed.
At this time, the LED illumination 36 mounted on the first surface 31 a of the flexible substrate 31 is housed in the recess 28 provided on the pasting surface 27 and faces the bottom surface 28 d of the recess 28.

  Thus, in the structure which affixes the display panel 30 which has flexibility on the sticking surface 27 comprised by the convex curve, the display panel 30 is comprised with the flexible board | substrate 31 and print sheet 32 which set thickness thinly.

  Then, the LED illumination 36 is mounted on the first surface 31a facing the pasting surface 27 of the flexible substrate 31, while the pasting surface 27 accommodates the LED lighting 36 mounted on the first surface 31a. And the recessed part 28 which functions as a reflection part is provided.

  As a result, in spite of mounting the LED illumination 36 on the affixing surface 27 side of the flexible substrate 31, the display panel 30 set to be thinner than the conventional one is adhered and fixed to the affixing surface 27 formed of a convex curved surface. Can do.

  In addition, the thickness of the display panel 30 is set to be thinner than a conventional display panel having a relatively thick thickness, which may be peeled off due to the force of returning to a flat state even when pasted on a conventional convex curved surface. It is. For this reason, the display panel 30 can be more reliably and easily attached and fixed to the convex curved surface.

Further, since the thickness of the flexible substrate 31 constituting the display panel 30 is set thin, the bending stress of the flexible substrate 31 is greatly reduced. As a result, the force to peel off the panel 30 that always works on the display panel 30 in a state of being stuck and fixed to the convex curved sticking surface 27 is greatly reduced.
As a result, the display panel 30 is stably stuck and fixed to the sticking surface 27.

  Furthermore, by setting the thickness dimension of the display panel 30 to be small, the deformation amount of expansion or contraction when the temperature difference changes greatly or when the humidity difference changes greatly becomes small. For this reason, the malfunction which the display panel 30 peels from the sticking surface 27 by temperature change or humidity change can be prevented.

  Note that the assembly order of the display panel 30 is not limited to the above-described procedure. That is, the flexible substrate on which the double-sided tape on the first surface 31 a of the flexible substrate 31 is attached to the attaching surface 27 of the front plate 22, and then the double-sided tape on one plane 32 a of the printing sheet 32 is attached to the attaching surface 27. The CCU 3 may be configured such that the display panel 30 is provided on the front plate 22 by being attached to the second surface 31 b of the 31.

  In the above-described embodiment, the flexible substrate 31 and the print sheet 32 are each provided with a double-sided tape in advance. However, the flexible substrate 31 and the print sheet 32 may be provided with a glue surface having a predetermined adhesive strength. Specifically, a configuration in which an adhesive surface is provided at a predetermined position on the flexible substrate 31 or a configuration in which an adhesive surface is provided at a predetermined position on the print sheet 32 may be employed.

  In the CCU 3 described above, when the LED illumination 36 is turned on based on an instruction from the control unit, white light is emitted from the LED illumination 36 toward the bottom surface 28d of the recess 28 as indicated by an arrow Y8A in FIG.

  The white light emitted toward the bottom surface 28d is reflected by the white reflecting surface of the bottom surface 28d, and then reflected directly or again by the white reflecting surface of the inner peripheral surface 28s, and then the LED of the flexible substrate 31. It goes toward the portion where the illumination 36 is mounted and its periphery.

  The reflected light toward the flexible substrate 31 reaches the first surface 31a of the flexible substrate 31 directly or as indicated by the arrow Y8B or around the LED illumination 36 as indicated by the arrow Y8C. It penetrates into the substrate 31.

  The reflected light that has entered the flexible substrate 31 is emitted from the second surface 31b of the flexible substrate 31 directly or around the wiring 31l electrically connected to the LED electrical contact 31c.

  The reflected light emitted from the second surface 31b, that is, the orange transmitted light transmitted through the flexible substrate 31, passes through the filter portion 32f provided on the one plane 32a side of the light transmitting portion 32e of the print sheet 32. Then, it goes to the light transmission part 32e. The orange transmitted light is changed to a desired color by passing through the filter portion 32f, and is emitted to the outside from the other plane 32b of the light transmitting portion 32e. As a result, the light transmission part 32e emits light in a desired color.

  Note that the amount of light that wraps around can be increased by increasing the amount of light of the LED illumination 36.

  In this way, the white light emitted from the LED illumination 36 is emitted toward the bottom surface 28d that is the reflection surface of the recess 28 that is spaced apart from the LED illumination 36 by a predetermined distance. As a result, the light transmitting portion 32e does not emit light by the white light directly emitted from the LED illumination 36 toward the print sheet 32, but the reflected light reflected by the bottom surface 28d and the reflected light reflected by the inner peripheral surface 28s. Emitted by light.

For this reason, in this embodiment, the distance from the LED illumination 36 to the printing sheet 32 becomes a long distance. As a result, only the central light transmitting portion 32e is brighter, it is possible to color the grayed La Defense Shon from the center toward the outer diameter to prevent hot spots phenomenon occurs.

  Further, the LED illumination 36 and the wiring 31l that can be a projected object are disposed between the bottom surface 28d that is a reflection surface and the print sheet 32, so that there is a possibility that a shadow may be generated. However, the problem of the occurrence of this shadow is solved by not only making the bottom surface 28d of the recess 28 a reflective surface, but also reflecting the inner peripheral surface 28s and making the reflective surface a diffuse reflective surface. That is, the reflected light is circulated to the LED illumination 36 and the wiring 31l to prevent the occurrence of shadows. In addition, a wraparound space for the thickness of the double-sided tape and the thickness of the polyimide film 31p is provided on the back side of the LED illumination 36.

  As a result, the reflected light wraps around the LED illumination 36, and as shown in FIG. 10, the LED illumination 36 and the wiring 31l indicated by the broken line are prevented from being shaded and adversely affecting the light emission state of the light transmitting portion 32e.

  As described above, the display panel 30 composed of the flexible substrate 31 and the print sheet 32 is attached to the convex curved attachment surface 27 provided on the front plate 22 of the housing 21. As a result, an electric device provided with the display panel 30 having excellent visibility can be provided at low cost.

  In the above-described embodiment, the electric device is a CCU to which an endoscope is connected. However, the electrical equipment is not limited to the CCU, and has a housing such as an image processing equipment such as a video equipment, a computer such as a personal computer, various control boxes such as a signal processing equipment, and a communication equipment such as a wireless signal processing machine. It is the electric equipment which is comprised by this and operate | moves with an electrical energy or an electrical signal.

  The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the invention.

  This application is filed in Japanese Patent Application No. 2014-066591 filed in Japan on March 27, 2014 as a basis for claiming priority, and the above disclosure includes the present specification, claims, It shall be cited in the drawing.
