Description

  The present invention relates to a display device that can be used for, for example, a vehicle meter unit that displays instruments such as a speedometer and a tachometer, and more particularly to a display device that can perform graphic display.

  Conventionally, as a meter unit for a vehicle, an analog meter that displays information indicating a vehicle state such as a vehicle speed and an engine rotational speed by physically moving a pointer, or a digital meter that displays information by digital display of numerical values and characters. It has been known.

  In recent years, a liquid crystal display panel or the like that can display an arbitrary image graphically by combining a large number of pixels whose display modes can be individually controlled is available at a relatively low cost. For this reason, attempts have been made to realize display of instruments and the like in the meter unit using various graphic displays.

  For example, in Patent Document 1, various instruments can be displayed by displaying an image on the screen of a liquid crystal display panel.

  By the way, when the graphic display is adopted in the meter unit, the contents to be displayed can be freely expressed in various forms. However, even if a graphic display is adopted, it is required to display the same content as a conventional analog meter having a pointer on the display screen of the meter unit in order to emphasize visibility during driving. Tend to be.

  In this way, when using an expression method equivalent to that of an analog meter, the vehicle user recognizes that the display is the same as the old visual display, even though it employs a highly functional graphic display. There was a risk of it. That is, since the user cannot feel a novelty or a special high-class feeling, there is a possibility that a special added value corresponding to the graphic display cannot be generated even if the graphic display is adopted.

  The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a display device with improved display mode.

The above object of the present invention is achieved by a display device having the following configuration.

According to the display device having the configuration (1), at least the outline is blurred on the first display element (for example, speedometer) for presenting information (for example, vehicle speed) regarding the vehicle state. The circular second display element that changes in size and is displayed in the state guides the user's gaze position to the first display element when the display device transitions to the normal display state. For this reason, at the start of operation (that is, at the start of display), the user can be prompted to view the first display element, which is a meter, for example. Further, since the second display element is displayed with the outline being blurred, the display content in the first display element is not complete (not the display content in the normal display state) to the user. It can also be recognized. In addition, the display contents rich in change can give the user a novel impression different from that of a general analog meter.
According to the display device having the configuration of (2) above, the display in the normal display state is similar to the display of the conventional analog instrument, and the display at the start of display is different from the conventional display while ensuring the visibility during operation. It can be innovative. Further, at the start of the change in the display state of the second display element, only the display elements having the circular outer shape (outer frame and second display element) are displayed, and thereafter, according to the change in the display state of the second display element. , Other display elements are displayed. For this reason, a display with a sense of unity can be realized.
According to the display device having the configuration (3), the display density or brightness of the second display element displayed on the first display element changes, so the display state of the first display element changes. This makes it easier for the user to recognize that the user is doing.
According to the display device having the configuration (4), the display color of the second display element is changed when the change in the display state of the second display element is switched from enlargement to reduction. You can attract the user's attention to the element.

  According to the display device of the present invention, it is possible to provide a display device with improved display mode.

  The microcomputer 111 is a control unit, and performs processing for realizing various functions required for the meter unit 100 by executing a control program prepared in advance. Specifically, the latest vehicle data including vehicle speed, cooling water temperature, fuel remaining amount, engine rotation speed, etc. is collected via the I / O unit 114, necessary calculations are performed, and data to be displayed is displayed. Generate. Then, the obtained information is reflected in the display contents of each display unit on the display screen 50 of the liquid crystal display 121. That is, the microcomputer 111 (control unit) has a function of controlling the display content of the liquid crystal display 121 (display unit).

  The CPU power supply 112 receives DC power (+ B) supplied from a power circuit on the vehicle side, and generates a stable DC voltage (Vcc) necessary for the circuit of the microcomputer 111 and the like to operate. Further, the CPU power source 112 can generate a reset signal and supply it to the microcomputer 111, or can control the voltage according to a sleep control signal output from the microcomputer 111.

  The I / O unit 113 performs signal processing for converting the ignition signal (IGN +) output from the vehicle side into a voltage that can be input by the microcomputer 111.

  The I / O unit 114 performs signal processing necessary for connecting the microcomputer 111 to a communication network (CAN: Controller Area Network) on the vehicle. The microcomputer 111 has a built-in communication function corresponding to the CAN standard. Therefore, the microcomputer 111 communicates with various electronic control devices (ECU: Engine Control Unit, not shown) on the vehicle via the I / O unit 114 and the communication network on the vehicle. Can do. By this communication, for example, vehicle data such as a vehicle speed and an engine rotation speed can be acquired.

  The non-volatile memory 116 is configured by an EEPROM, and is used to hold various fixed data used by the meter unit 100. Specifically, programs executed by the microcomputer 111 and fixed data such as various constants are written in the nonvolatile memory 116 in advance.

  The liquid crystal display 121 (display unit) is, for example, a TFT-LCD, and has a two-dimensional array display screen 50 composed of a large number of pixels arranged in the horizontal (X) direction and the vertical (Y) direction. This is a device capable of displaying various images graphically by combining the pixels. By controlling from the outside, the density (or brightness) and display color of each of the large number of pixels can be switched individually.

<Operation of display device>
<Overview>
FIG. 3 and FIG. 4 show state transitions at the start of display of the display screen 50 shown in FIG. FIG. 5 shows a processing procedure at the start of display of the display device shown in FIG.

  That is, when the microcomputer 111 starts the display of the display screen 50 by executing the processing procedure shown in FIG. 5, the display contents are sequentially changed as shown in FIGS. That is, the display screen 50A shown in FIG. 3 is first displayed, and the display contents change to the display screens 50B and 50C as time passes. Furthermore, after the display screen 50C is displayed, the display screen 50D is changed to the display screen 50D shown in FIG.

<Specific operation>
A processing procedure of the microcomputer 111 shown in FIG. 5 and a specific change in display contents on the display screen 50 will be described below. In the processing procedure described below, the microcomputer 111 controls the liquid crystal display 121 to explain the content of the processing to change the display content of the liquid crystal display 121. However, the description is simplified and understood. For ease of description, the microcomputer 111 may be described in a simplified manner that the display content is changed (or changed).

  In step S11, the microcomputer 111 identifies on / off of the ignition (IGN), and when detecting that the ignition has been switched on, the microcomputer 111 proceeds to processing in step S12 and subsequent steps. That is, when the user turns on the ignition switch in order to start driving the vehicle, the microcomputer 111 executes the processing from step S12 onward in order to start the display operation of the meter unit 100. That is, the operation described below is an operation executed at the start of display before transitioning to the normal display state.

  In step S12, the microcomputer 111 displays on the display screen 50 of the liquid crystal display 121 the outer frame 51a of the speedometer 51, the tachometer 52, the fuel gauge 53, and the water temperature gauge 54, which are the first display elements. Only 52a, 53a, and 54a are displayed as the initial state. In this initial state, on the display screen 50, the outer frame 51a disposed on one end side, the outer frame 52a disposed on the other end side opposite to the outer frame 51a, and the outer frame 51a. An outer frame 53a arranged to have a portion overlapping with the outer frame 51a on the other end side, and an outer frame 54a arranged to have a portion overlapping with the outer frame 52a closer to one end side than the outer frame 52a. Is displayed. Further, the outer frame 51a is displayed in the overlapping portion between the outer frame 51a and the outer frame 53a, and the outer frame 52a is displayed in the overlapping portion between the outer frame 52a and the outer frame 54a.

  In step S13, the microcomputer 111, in addition to the speedometer 51, the tachometer 52, the fuel gauge 53, and the water temperature gauge 54, as in the display screen 50A shown in FIG. , 54a, a blur display element (second display element) having a circular shape that is similar to the outer shape of the outer frames 51a, 52a, 53a, 54a is displayed in a small state. In the present embodiment, the blur display elements 71A, 72A, 73A, and 74A are displayed on the outer frames 51a, 52a, 53a, and 54a, respectively, in a state where the entire outline including the outline is blurred.

  Since each of the blur display elements 71A, 72A, 73A, and 74A has been subjected to blurring processing, the contour shape, the coloring inside the area, and the boundary of brightness are displayed in an unclear situation. For example, such blur display elements can be displayed by preparing in advance data of elements subjected to blur processing and pasting this data on the screen (writing on the image memory). Alternatively, such a blur display element can be displayed by performing a blur process for each display process of image data corresponding to the blur display elements 71A, 72A, 73A, and 74A.

  In step S14, the microcomputer 111 gradually enlarges the display of each blur display element 71A, 72A, 73A, 74A displayed in step S13 as time passes. For example, the enlarged blur display elements 71B, 72B, 73B, and 74B are displayed as in the display screen 50B shown in FIG.

  The blur display elements 71B, 72B, 73B, and 74B are elements similar in shape to the blur display elements 71A, 72A, 73A, and 74A, respectively, and are different only in size. Actually, the display size of the display is reduced by gradually expanding the display elements 71A, 72A, 73A, and 74A to be displayed step by step or continuously with time. It can be enlarged like 72B, 73B, 74B.

  Further, in parallel with increasing the size of the blur display elements 71A, 72A, 73A, 74A in step S14, the microcomputer 111 gradually increases the display density of these elements or increases the brightness. To change the display state.

  In step S15, the microcomputer 111, as with the display screen 50B shown in FIG. 3, like the display screen 50B shown in FIG. 3, the scales 51b, 52b are arranged on the outer periphery of the outer frames 51a, 52a, 53a, 54a. , 53b, 54b are displayed. The scales 51b, 52b, 53b, 54b are further moved to a predetermined position in a predetermined order in the next step S16.

  For example, for the speedometer 51 in the display screen 50B shown in FIG. 3, after each of the plurality of scales 51b of the speedometer 51 is displayed at the outer peripheral position of the outer frame 51a, the scale position in the normal display state (that is, The two move together to draw an arc toward the position shown in FIG. This also applies to the other scales 52b, 53b, 54b. Here, as shown in FIG. 3, the scale 51b and the scale 53b, and the scale 52b and the scale 54b are different in the moving direction so as to draw an arc. That is, they move so that the movement trajectory is the target in the left-right direction in the figure.

  In step S17, the microcomputer 111 switches the display color of the blur display elements 71B, 72B, 73B, and 74B already displayed in the area of each instrument to a different color.

  In step S18, the microcomputer 111 displays the remaining display elements as in the display screen 50C shown in FIG. That is, the symbol elements 51c, 52c, 53c, 54c, the pointers 51d, 52d, 53d, 54d, and other display elements are displayed.

  In step S19, the microcomputer 111 gradually increases the size of the blur display element already displayed in the area of each instrument as time elapses, as in the display screen 50B to the display screen 50D shown in FIG. To be finally erased from the screen.

  That is, the blur display elements 71B, 72B, 73B, and 74B in the display screen 50B shown in FIG. 3 are reduced in size like the blur display elements 71C, 72C, 73C, and 74C in the display screen 50C, and further FIG. Is finally erased through the states of the blur display elements 71D, 72D, 73D, and 74D in the display screen 50D.

  In addition, the hands 51d, 52d, 53d, and 54d displayed in step S18 are gradually displayed as time passes. That is, from the state shown in the display screen 50C, the area displayed like the display screen 50D increases little by little, and the whole is displayed in the state of the display screen 50E. That is, in the present embodiment, the blur display element has a portion overlapping with the pointers 51d, 52d, 53d, and 54d displayed at the center at the center of each outer frame 51a, 52a, 53a, and 54a. Arranged and a blur display element is displayed in the overlapping portion. Then, as the blur display element is reduced, the overlapping portion is reduced, whereby the pointers 51d, 52d, 53d, and 54d are displayed so that the display area gradually increases, and the display is started.

  Further, in parallel with reducing the blur display elements 71A, 72A, 73A, and 74A in step S19, the microcomputer 111 gradually displays the display density so that the display density of these elements becomes lighter or the brightness becomes darker. To change.

  In step S19, the microcomputer 111 displays a vehicle image 61 that simulates the outer shape of the host vehicle at substantially the same timing as the deletion of the blur display element. Specifically, as shown in the vehicle image 61A shown in FIG. 4, a part of the vehicle appears from the periphery of the display screen 50D, and the vehicle moves while traveling upward as shown in the display screen 50E. Displayed as an image 61B, and further moves to the center of the display screen 50F as a vehicle image 61C to complete the display.

  In step S20, the microcomputer 111 performs display control so that the display content of the display screen 50 functions as a normal meter unit for automobiles. That is, the latest vehicle speed information is acquired, and the display content is updated so that this vehicle speed is reflected in the display position and orientation of the pointer 51d of the speedometer 51. In addition, the latest engine rotation speed information is acquired, and the display contents are updated so that the engine rotation speed is reflected in the display position and orientation of the pointer 52 d of the tachometer 52. The same applies to other display elements such as the fuel gauge 53 and the water temperature gauge 54.

  As described above, when the user (vehicle driver) tries to start driving the vehicle, the display screens 50A, 50B shown in FIG. 3 and FIG. The user visually recognizes display states such as 50C, 50D, 50E, and 50F in order.

  That is, at the beginning of the display, as an initial state, only the annular outer frames 51a, 52a, 53a, 54a of the speedometer 51, the tachometer 52, the fuel gauge 53, and the water temperature gauge 54, which are the first display elements, are provided. After that, the blurred display element (second display element) is displayed in a small size in the center of these outer frames 51a, 52a, 53a, 54a. These blur display elements are enlarged and reduced after time, and then erased. In conjunction with the change in the display state of the blur display element, the display mode of the speedometer 51, the tachometer 52, the fuel gauge 53, and the water temperature gauge 54 changes from the initial state to the display mode in the normal display state. More specifically, the scales 51b, 52b, 53b, and 54b, the symbol elements 51c, 52c, 53c, and 54c, the pointers 51d, 52d, 53d, and 54d are displayed as described above according to the change in the display state of the blur display element. Are started sequentially. Accordingly, the user's line of sight is guided to each blur display element, and the user sees the speedometer 51, the tachometer 52, the fuel gauge 53, and the water temperature gauge 54 displayed while being gradually changed. Therefore, according to the meter unit 100 according to the embodiment, in the normal display state, even when the display screen 50 having the same display form as that of a general analog meter is employed as shown in FIG. The novel display mode described above allows the user to feel that the meter is a highly functional meter that is completely different from the analog meter.

  Below, the effect | action and effect of the display apparatus which concern on this embodiment are demonstrated.

The display device according to the present embodiment includes a liquid crystal display 121 (display unit) capable of displaying an arbitrary image by combining a large number of pixels whose display modes can be individually controlled, and can present information on the state of the vehicle. It is a display device. The liquid crystal display 121 has a circular speedometer 51, a tachometer 52, a fuel gauge 53, and a water temperature gauge 54 (first display element) for presenting information related to the state of the vehicle, and at least the outline is blurred. It is possible to display a circular blur display element (second display element) displayed on the first display element in a state of being displayed. Further, when the display device is in the normal display state, the liquid crystal display 121 displays the first display element in a predetermined state and does not display the second display element (see FIG. 1). Then, at the start of the display before the display device transitions to the normal display state, the liquid crystal display 121 enlarges the second display element with the passage of time, reduces it, and then erases it. In conjunction with the change in the display state of the second display element, the first display element is transitioned from the initial state to the predetermined state.
Thereby, for example, the user's gaze position at the start of the display is displayed on the speedometer 51 for presenting the vehicle speed, which is information related to the state of the vehicle. 51. For this reason, the user can be prompted to look at the speedometer 51 at the start of operation. Moreover, since the blur display element is displayed with the outline being blurred, it is possible to make the user recognize that the display content on the speedometer 51 is not complete. The same applies to the tachometer 52, the fuel gauge 53, and the water temperature gauge 54. In addition, the display contents rich in change can give the user a novel impression different from that of a general analog meter.

And a plurality of scales (51b, 52b, 53b, 54b) constituting the scale together with the outer frame, and arranged near the center of the outer frame, pointing to a part of the scale and And pointers (51d, 52d, 53d, 54d) for presenting the state quantities. Then, the liquid crystal display 121 displays only the outer frame of the first display element as the initial state before the change of the display state of the blur display element at the start of display, and displays the blur display element. In accordance with the state change, the display of the scale and the pointer is started sequentially.
As a result, the display in the normal display state can be made a display that is similar to a conventional analog instrument to ensure visibility during operation, and the display at the start of display can be made different from the conventional display. Further, at the start of the change in the display state of the second display element, only the display elements having the circular outer shape (outer frame and second display element) are displayed, and thereafter, according to the change in the display state of the second display element. , Other display elements are displayed. For this reason, a display with a sense of unity can be realized.

In the display device according to the present embodiment, the liquid crystal display 121 displays both the display density and the brightness of the blur display element according to the change in the display state both when the blur display element is enlarged and when the blur display element is reduced. Is changed (step S14, step S19).
Thereby, it can make it easy for a user to recognize that the display state of the speedometer 51, the tachometer 52, the fuel gauge 53, and the water temperature gauge 54 is changing.

In the display device according to the present embodiment, the liquid crystal display 121 changes the display color of the blur display element at the time when the change in the display state of the blur display element is switched from enlargement to reduction (step S17).
Thereby, the user's attention can be attracted to the blur display element.

  The technical scope of the present invention is not limited to the embodiment described above. The above-described embodiments can be accompanied by various modifications and improvements within the technical scope of the present invention.

  For example, in the present embodiment, four meters, that is, a speedometer 51, a tachometer 52, a fuel meter 53, and a water temperature meter 54 are displayed as the first display element, but at least one of these is displayed. Any other configuration may be used, and another instrument may be displayed as the first display element.

  Further, in the present embodiment, the blur display element is configured to be displayed in a state where the entire outline including the outline is blurred. However, at least the outline may be blurred, for example, only the outline is blurred. It may be configured to be displayed in a state.

  In the present embodiment, the speedometer 51 in the display screen 50B shown in FIG. 3 is displayed in the normal display state after each of the plurality of scales 51b of the speedometer 51 is displayed at the outer peripheral position of the outer frame 51a. Although it is configured to move so as to draw an arc toward the scale position (that is, the position shown in FIG. 1), each of the plurality of scales 51b that enter the display screen in order from the lower center of the display screen It may be configured to move to the scale position in the normal display state so as to draw an arc along the frame 51a. Alternatively, each of the plurality of scales 51b displayed in the central portion of the outer frame 51a may be configured to move radially to the scale position in the normal display display state. In the embodiment, each of the plurality of graduations is configured to move together, but may be configured to move sequentially from the end.

  In the present embodiment, both the display density and the brightness of the blur display element are changed according to the change in the display state both when the blur display element is enlarged and reduced. Any structure may be used as long as at least one of the display density and the brightness of the blurred display element is changed when enlarging or reducing the element.

  In the present embodiment, the speed indicator 51, the tachometer 52, the fuel gauge 53, and the water temperature gauge 54, which are the first display elements, have a circular shape, but may have a substantially circular shape, for example, an elliptical shape. It doesn't matter. That is, the outer shape of the annular outer frames 51a, 52a, 53a, 54a may be elliptical. In this case, if the blur display element as the second display element is similarly formed into an elliptical shape, the first display element and the second display element are similar to each other to provide a uniform display. Can do.
