Disclosure of Invention
Technical problem to be solved by the invention
In the operation display device of patent document 1, the liquid crystal panel is a simple liquid crystal display based on a segment method. Thus, the displayed content and its position are fixed. Therefore, in order to include a plurality of displays within a limited range in the liquid crystal panel, the number of displays and the size of each display are limited. Therefore, it is difficult to improve visibility of display in the liquid crystal panel.
In the liquid crystal panel as in patent document 2, various display states can be switched and displayed. Therefore, visibility can be easily improved. However, the liquid crystal panel having a high degree of freedom of display as in patent document 2 is expensive.
The invention aims to improve the visibility of an operation display device at low cost.
Technical solution for solving technical problem
One embodiment of the present invention is an operation display device for operating an apparatus, including an operation display panel, a light guide plate, a light source, and a control section. The operation display panel includes an operation section for operating the device and a display section for displaying information related to the device. The light guide plate is made of a light-transmitting material and is disposed to overlap the operation display panel. The light source irradiates light from the end face of the light guide plate toward the inside of the light guide plate. The control unit controls the light source. The light guide plate includes a plurality of prisms. The plurality of prisms reflect light from the light source to display a predetermined pattern on the surface of the light guide plate. The control unit controls the light source to switch the display of a predetermined pattern.
In the operation display device of the present embodiment, a predetermined pattern can be displayed on the surface of the light guide plate disposed to overlap with the operation display panel. Further, the operation display panel can be easily visually recognized by not displaying a predetermined pattern when not necessary. Therefore, the degree of freedom in the size and position of the pattern displayed on the light guide plate is high. Therefore, visibility can be easily improved. The predetermined pattern displayed on the light guide plate can be adjusted by the shape and arrangement of the prisms. Therefore, the cost can be reduced compared to the case of using a liquid crystal panel having a high degree of freedom in display.
The predetermined pattern may be displayed so as to overlap at least a part of the display unit. In this case, regardless of the arrangement of the display unit, the pattern can be displayed in a conspicuous manner and in a large size.
The control unit may switch between display and non-display of a predetermined pattern. In this case, when display is not necessary, the pattern is not displayed, thereby preventing visibility of the operation display panel from being impaired.
The control unit may switch the display of the predetermined pattern in accordance with an operation of the operation unit. In this case, the user can visually and easily understand the operation of the operation unit.
The predetermined pattern may be a pattern that highlights at least a part of the display unit. In this case, the visibility of at least a part of the display portion can be improved by the predetermined pattern displayed on the light guide plate.
The predetermined pattern may include characters, symbols, or icons that are larger than the characters, symbols, or icons included in the display unit. In this case, the characters, symbols, or icons having higher visibility than the characters, symbols, or icons included in the display portion can be displayed on the light guide plate.
The prescribed pattern may include a plurality of mode displays representing the operational modes of the device. The control unit may switch the mode display according to the operation mode of the device. In this case, the user can visually and easily grasp the operation mode of the apparatus.
The prescribed pattern may include a plurality of warning displays. The control unit may switch the warning display according to the state of the device. In this case, the user can visually and easily grasp the state of the apparatus.
The prescribed pattern may include a parameter display representing a prescribed parameter associated with the device. The control unit may switch the parameter display according to a change in the parameter. In this case, the user can easily grasp the change of the parameter visually.
The parameter display may include a plurality of sections. The plurality of prisms may be arranged to correspond to the plurality of segments, respectively. The control unit may display the parameter by switching between display and non-display of each of the plurality of segments. In this case, the user can visually and easily grasp the change in the parameter by the display and non-display of the plurality of segments.
The parameter display may include a seven segment display. The control unit may display the parameter numerically by seven-segment display. In this case, the user can easily visually grasp the change in the parameter from the numerical value displayed in the seven steps.
The prescribed pattern may include a 1 st parameter display representing a 1 st parameter related to the device and a 2 nd parameter display representing a 2 nd parameter different from the 1 st parameter. The control unit may switch between displaying the 1 st parameter display and the 2 nd parameter display. In this case, the 1 st parameter display and the 2 nd parameter display which are different from each other can be switched and displayed as necessary.
The display portion may also include a liquid crystal display. The predetermined pattern may be displayed in superimposition with the liquid crystal display. In this case, the display of the liquid crystal display can be assisted by a predetermined pattern. Therefore, even if a liquid crystal display with low cost is used, the degree of freedom of display can be improved.
The display unit may include a plurality of print displays. The predetermined pattern may include a plurality of irradiation patterns corresponding to a plurality of print displays. The control unit may be configured to display at least one of the plurality of irradiation patterns to irradiate at least one selected from the plurality of print displays. In this case, at least one selected from the plurality of print displays can be highlighted. Further, the cost can be reduced as compared with a device in which a light source such as a diode corresponding to the selected indicator is caused to emit light from the back side of the printed display.
The light source may emit light of a color different from the display color of the display unit. In this case, the display of the display unit can be assisted by the color of the predetermined pattern. Therefore, even if a display unit with low cost, for example, a monochrome display unit is used, the degree of freedom of display can be improved.
Effects of the invention
According to the present invention, the visibility of the operation display device can be improved at low cost.

Detailed Description
Hereinafter, an operation display device according to an embodiment will be described with reference to the drawings. Fig. 1 is a schematic diagram showing a configuration of an operation display device 1. The operation display device 1 includes an operation display panel 2 and a light guide panel display 3. The operation display panel 2 includes an operation unit 4 and a display unit 5. The operation unit 4 is a switch for operating the device provided with the operation display device 1. The display section 5 displays information related to the device.
The light guide panel display 3 includes a light guide panel 10, a plurality of light sources 11 and 12, a control unit 13, and a storage unit 14. The light guide plate 10 is disposed to overlap the operation display panel 2. The light guide plate 10 is disposed to overlap the display unit 5. The light guide plate 10 is formed of a light transmissive material. The light guide plate 10 is made of a transparent resin such as polymethyl methacrylate (PMMA), polycarbonate, or cycloolefin polymer.
The plurality of light sources 11 and 12 irradiate light from the end surface of the light guide plate 10 toward the inside of the light guide plate 10. The plurality of light sources 11,12 includes a 1 st light source 11 and a 2 nd light source 12. The light sources 11,12 are for example light emitting diodes. However, light sources other than light emitting diodes may be used. The light sources 11 and 12 are turned on and off in accordance with a control signal from the control unit 13.
The control Unit 13 includes a processor such as a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), and the like. The storage unit 14 is an auxiliary storage device such as a hard disk drive or a solid state disk. The control unit 13 controls the light sources 11 and 12 based on the program and data stored in the storage unit 14.
The light guide plate 10 includes a plurality of prisms 20 that display a predetermined pattern on a surface of the light guide plate 10. Fig. 2 is a schematic diagram showing an example of the structure of the light guide plate 10. As shown in fig. 2, the prism 20 is disposed on the rear surface 15 of the light guide plate 10. The arrangement of the prisms 20 is: the light from the light source 11 or 12 is reflected to the surface 16 of the light guide plate 10, whereby a predetermined pattern is displayed on the surface 16 of the light guide plate 10. In the drawings, the prism 20 is shown in a highlighted manner, and therefore is different from the actual size.
Fig. 3 is a diagram showing an example of the prism 20. In the example shown in fig. 3, the prism 20 is a groove in the shape of a triangular pyramid. The prism 20 includes a reflective surface 201 and diffusing surfaces 202, 203. The reflecting surface 201 is arranged to totally reflect light from a specific light source (one of the light sources 11 and 12) and emit the light from the surface 16 of the light guide plate 10 into a predetermined visual field range. The predetermined visual field range is a predetermined angular range with respect to the normal direction of the surface 16 of the light guide plate 10, and is a range in which a user operating the display device 1 can visually confirm the pattern of the light guide plate 10. The diffusion surfaces 202 and 203 are arranged so as to reflect in a direction outside a predetermined visual field range, so that a user cannot visually recognize light from a light source other than a specific light source.
The light guide plate 10 can display a plurality of patterns. The plurality of patterns include, for example, a 1 st pattern 31 shown in fig. 4 and a 2 nd pattern 32 shown in fig. 5. The plurality of prisms 20 of the light guide plate 10 include a plurality of 1 st prisms 21 shown in fig. 4 and a plurality of 2 nd prisms 22 shown in fig. 5. The 1 st prisms 21 are arranged along the 1 st pattern 31. The plurality of 2 nd prisms 22 are arranged along the 2 nd pattern 32. In the drawings, reference numerals are given to only a part of the 1 st prism 21 and the 2 nd prism 22.
The 1 st prism 21 is arranged in such a manner as to reflect light from the 1 st light source 11 and display the 1 st pattern 31 on the surface 16 of the light guide plate 10. The 2 nd prism 22 is arranged in such a manner as to reflect the light from the 2 nd light source 12 and display the 2 nd pattern 32 on the surface 16 of the light guide plate 10.
The control unit 13 controls the turning on and off of the 1 st light source 11 and the 2 nd light source 12 to switch the display of the 1 st pattern 31 and the 2 nd pattern 32, and the control unit 13 turns on the 1 st light source 11 and turns off the 2 nd light source 12, for example. Thereby, as shown in fig. 4, only the 1 st pattern 31 is displayed on the light guide plate 10. When the controller 13 turns on the 2 nd light source 12 and turns off the 1 st light source 11, only the 2 nd pattern 32 is displayed on the light guide plate 10 as shown in fig. 5.
When the control unit 13 turns off both the 1 st light source 11 and the 2 nd light source 12, both the 1 st pattern 31 and the 2 nd pattern 32 are not displayed. When the controller 13 turns on both the 1 st light source 11 and the 2 nd light source 12, both the 1 st pattern 31 and the 2 nd pattern 32 are displayed on the light guide plate 10. In the example shown in fig. 4 and 5, the 1 st pattern 31 and the 2 nd pattern 32 are disposed at positions overlapping each other in the light guide plate 10. However, in the light guide plate 10, the 1 st pattern 31 and the 2 nd pattern 32 may be separately disposed.
Fig. 6 is a view showing a 1 st display example of the operation display panel 2 and the light guide panel display 3. The operation unit 4 includes a plurality of operation switches 17 and 18. The operation switches 17 and 18 are, for example, push-button switches. The operation switches 17 and 18 may be mechanical switches such as slide switches or rotary switches. The operation switches 17 and 18 may be touch panel switches. The operation switches 17 and 18 include switches for starting the device process or inputting the device setting. The plurality of operation switches 17, 18 include a 1 st switch 17 and a 2 nd switch 18.
The display section 5 includes a liquid crystal display 19. The liquid crystal display 19 is, for example, a seven-segment display. The display section 5 displays the parameters relating to the device in numerical values on the liquid crystal display 19. The liquid crystal display 19 displays parameters related to the time of the apparatus, for example, in numerical values. The liquid crystal display 19 displays a parameter relating to the amount of a substance used in the apparatus, for example, in numerical values.
The display unit 5 includes a plurality of print displays 33 and 34. The print displays 33, 34 correspond to, for example, settings assigned to the operation switches 17, 18, respectively. The plurality of printed displays 33, 34 includes a 1 st display 33 and a 2 nd display 34. The 1 st display 33 corresponds to the 1 st setting assigned to the 1 st switch 17. The 2 nd display 34 corresponds to the 2 nd setting assigned to the 2 nd switch 18.
As shown in fig. 6(a), the light guide plate 10 is disposed to overlap the display unit 5. Since the light guide plate 10 is transparent, if the controller 13 does not display the pattern of the light guide plate 10, the user can visually recognize the entire display of the display unit 5.
When the control unit 13 turns on the 1 st light source 11, the 1 st pattern 31 is displayed on the light guide plate 10 as shown in fig. 6 (B). The 1 st pattern 31 is displayed overlapping the liquid crystal display 19. Therefore, the 1 st pattern 31 can be displayed in a large area of the display unit 5.
When the controller 13 turns on the 2 nd light source 12, the 2 nd pattern 32 is displayed on the light guide plate 10 as shown in fig. 6 (C). Like the 1 st pattern 31, the 2 nd pattern 32 is displayed in superimposition with the liquid crystal display 19. Therefore, the 2 nd pattern 32 can be displayed in a large conspicuous manner in a wide range of the display unit 5.
For example, the 1 st pattern 31 is a display showing the 1 st setting. When the user presses the 1 st switch 17 to select the 1 st setting, the controller 13 displays the 1 st pattern 31 on the light guide plate 10. The 1 st pattern 31 is displayed larger than the 1 st display 33. The 2 nd pattern 32 is a display showing the 2 nd setting. When the user presses the 2 nd switch 18 to select the 2 nd setting, the controller 13 displays the 2 nd pattern 32 on the light guide plate 10. The 2 nd pattern 32 is shown larger than the 2 nd display 34.
Fig. 7 is a view showing a 2 nd display example of the operation display panel 2 and the light guide panel display 3. In fig. 7(a), as in fig. 6(a), both the 1 st pattern 31 and the 2 nd pattern 32 are not shown in the light guide plate 10. When the control unit 13 turns on the 1 st light source 11, the 1 st pattern 31 is displayed on the light guide plate 10 as shown in fig. 7 (B). In this example, the 1 st pattern 31 is displayed on the light guide plate 10 instead of the 1 st display 33 printed in the 1 st display 33 example. The 1 st pattern 31 is displayed at a position not overlapping the liquid crystal display 19. Therefore, the 1 st pattern 31 can be displayed without obstructing the display of the liquid crystal display 19.
When the controller 13 turns on the 2 nd light source 12, the 2 nd pattern 32 is displayed on the light guide plate 10 as shown in fig. 7 (C). In this example, the 2 nd pattern 32 is displayed on the light guide plate 10 instead of the printed 2 nd display 34 in the 1 st display 33 example. Like the 1 st pattern 31, the 2 nd pattern 32 is displayed at a position not overlapping the liquid crystal display 19. In addition, the 2 nd pattern 32 is displayed at a position different from the 1 st pattern 31. However, as in the case of the 1 st display example, the 2 nd pattern 32 may be displayed at a position overlapping the 1 st pattern 31.
Fig. 8 is a diagram showing a third display example of the operation display panel 2 and the light guide panel display 3. In fig. 8 (a), as in fig. 6(a), both the 1 st pattern 31 and the 2 nd pattern 32 are not shown on the light guide plate 10. When the control unit 13 turns on the 1 st light source 11, the 1 st pattern 31 is displayed on the light guide plate 10 as shown in fig. 8 (B). In this example, the 1 st pattern 31 highlights the 1 st display 33 that is printed. The 1 st pattern 31 highlights the 1 st display 33 by irradiating a position corresponding to the 1 st display 33.
When the controller 13 turns on the 2 nd light source 12, the 2 nd pattern 32 is displayed on the light guide plate 10 as shown in fig. 8 (C). The 2 nd pattern 32 highlights the 2 nd display 34 that is printed. The 2 nd pattern 32 highlights the 2 nd display 34 by irradiating a position corresponding to the 2 nd display 34. The light sources 11 and 12 may emit light of a color different from the display color of the display unit 5.
Fig. 9 is a diagram showing an example of the display 4 of the operation display panel 2 and the light guide panel display 3. In the 4 th display example, the control unit 13 switches the mode display according to the operation mode of the device. The operation modes include, for example, the 1 st mode and the 2 nd mode. In fig. 9 (a), as in fig. 6(a), both the 1 st pattern 31 and the 2 nd pattern 32 are not shown in the light guide plate 10.
When the device operation mode is the 1 st mode, as shown in fig. 9(B), the controller 13 turns on the 1 st light source 11 and displays the 1 st pattern 31 on the light guide plate 10. When the device operation mode is the 2 nd mode, the controller 13 turns on the 2 nd light source 12 to display the 2 nd pattern 32 on the light guide plate 10, as shown in fig. 9 (C). In this example, the 1 st pattern 31 and the 2 nd pattern 32 are characters indicating an operation mode, but may be symbols or icons.
The control unit 13 may display a pattern corresponding to the operation mode selected by the operation unit 4 on the light guide plate 10. Alternatively, the control unit 13 may automatically switch the operation mode and display a pattern corresponding to the currently executed operation mode on the light guide plate 10.
Fig. 10 is a diagram showing an example of the 5 th display of the operation display panel 2 and the light guide panel display 3. In the 5 th display example, the control unit 13 switches and displays a plurality of warning displays on the light guide plate 10 according to the state of the device. In fig. 10 (a), as in fig. 6(a), both the 1 st pattern 31 and the 2 nd pattern 32 are not shown in the light guide plate 10.
When the state of the device becomes the predetermined 1 st state, the controller 13 turns on the 1 st light source 11 to display the 1 st pattern 31 on the light guide plate 10 as shown in fig. 10 (B). The 1 st pattern 31 is a warning display corresponding to the 1 st state. When the state of the device is in the predetermined 2 nd state, the controller 13 turns on the 2 nd light source 12 to display the 2 nd pattern 32 on the light guide plate 10 as shown in fig. 10 (C). The 2 nd pattern 32 is a warning display corresponding to the 2 nd state. An example of the warning display is a display that prompts the user to deal with according to the state of the device. The warning display may also be an error code. The warning display is not limited to characters, but may be symbols or icons.
In addition, in the 1 st to 5 th display examples, the number of patterns is not limited to two, and may be one. Alternatively, the number of patterns may be three or more.
Fig. 11 is a view showing an example of display No. 6 of the operation display panel 2 and the light guide panel display 3. In the 6 th display example, the predetermined pattern constitutes a seven-segment display. Specifically, the predetermined pattern includes the 1 st to 7 th patterns 41 to 47. A plurality of 1 st to 7 th prisms 51 to 57 are provided on the light guide plate 10 corresponding to the 1 st to 7 th patterns 41 to 47, respectively. The control unit 13 displays the parameters of the device as numerical values by switching between the display and non-display of the 1 st to 7 th patterns 41 to 47, respectively. Although not shown, the light guide panel display 3 includes a plurality of light sources corresponding to the 1 st to 7 th patterns 41 to 47, respectively.
As shown in fig. 11(a), when the controller 13 turns off all of the plurality of light sources, all of the patterns on the light guide plate 10 are not displayed. As shown in fig. 11(B), when the controller 13 displays a part or all of the 1 st to 7 th patterns 41 to 47, the numerical value corresponding to the lit pattern is displayed on the light guide plate 10. The control section 13 displays a pattern corresponding to a numerical value representing a parameter of the device on the light guide plate 10. When the value indicating the parameter changes, the controller 13 changes the pattern displayed on the light guide plate 10 in accordance with the changed value. In fig. 11, a numerical value of 1 digit is displayed on the light guide plate 10, but a numerical value of 2 digits or more may be displayed on the light guide plate 10.
Fig. 12 is a diagram showing a 7 th display example of the operation display panel 2 and the light guide panel display 3. In the example shown in FIG. 7, the plurality of patterns 41 to 43 form a plurality of strip-shaped sections.
