Description

  The present invention relates to a vehicle display device that displays a warning image.

  Conventionally, various vehicle display devices for displaying various warning lights have been proposed, and for example, disclosed in Patent Document 1. Such a vehicle display device has a normal information display area in which normal information necessary for normal operation is displayed and a warning in which various warning displays are displayed on a display screen of a display panel installed in the instrument panel. And a display area. Furthermore, the display screen of the display panel is provided with an abnormality occurrence display area to notify the occurrence of abnormality in a predetermined area other than the normal information display area and the warning display area. The display area lights up or blinks in a predetermined emission color.

  On the other hand, Patent Document 2 discloses a vehicle display device including a liquid crystal display panel and a light source unit disposed on the back side of the liquid crystal display panel. This vehicle display device transmits and illuminates a liquid crystal display panel when emitted from a light source unit. The light source unit includes a first light source that emits light in a display color of a single color display or a predetermined color close to the display color, and a single color. And a second light source that is turned on when switching to a display other than the display.

JP-A-11-78611 Japanese Patent No. 3998575

The vehicle display device disclosed in Patent Document 1 has an advantage that when an abnormality occurs, almost all of the abnormality occurrence display area is lit or blinks, so that the occurrence of the abnormality can be recognized quickly. There is a possibility that it becomes difficult for the driver to visually recognize the warning content displayed in the warning display area.
Further, the vehicle display device disclosed in Patent Document 2 has a problem that the light source unit is expensive because the light source unit includes the first light source and the second light source.
The present invention has been made in view of these problems, and an object of the present invention is to provide an inexpensive vehicle display device capable of displaying a warning with excellent visibility.

  According to the present invention, the display panel 31 capable of displaying the warning images 74 and 75 and the control means 50 for displaying the warning marks 74a, 74b, 75a and 75b on the display panel 31, as described in claim 1. The control device 50 displays the warning marks 74a, 74b, 75a, and 75b in a first color, and borders of the warning marks 74a, 74b, 75a, and 75b. 74c, 74d, 75c, and 75d are blinked and displayed in the second color.

  According to a second aspect of the present invention, the control means 50 includes the warning image 74, 75 comprising the warning marks 74a, 74b, 75a, 75b and the edge portions 74c, 74d, 75c, 75d. Is displayed in black.

  According to a third aspect of the present invention, the control means displays the border portions 74c, 74d, 75c, and 75d so that the brightness of the second color gradually changes. .

  By displaying only the edge portion in a blinking manner without blinking the warning mark, a warning image with excellent visibility is obtained.

The front view which shows 1st embodiment of this invention. The block diagram which shows embodiment same as the above. Screen explanatory drawing which shows embodiment same as the above. Explanatory drawing which shows 2nd embodiment of this invention.

  Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. 1 to 3 show a first embodiment. The vehicle display device includes pointer-type meters 10 and 20 and a liquid crystal display 30.

  The pointer-type instrument 10 is a speedometer that displays the vehicle speed, and the pointer-type instrument 20 is a tachometer that displays the engine speed. The pointer-type meters 10 and 20 have dial plates 11 and 21 and pointers 12 and 22 and stepping motors 13 and 23, respectively. The dial plates 11 and 21 have indicator portions 11a and 21a indicated by the hands 12 and 22, respectively. The pointers 12 and 22 are rotated by the stepping motors 13 and 23 to indicate the indicator portions 11a and 21a of the dial plates 11 and 21.

  The turning member 40 is formed with circular openings 41 and 42 corresponding to the pointer type instrument 10 and the pointer type instrument 20 and a rectangular opening 43 corresponding to the liquid crystal display 30.

  FIG. 3 is a block diagram showing an electrical configuration of the vehicle display device. The microcomputer 50 has a CPU 51, ROM 52, and RAM 53. The speed sensor 61 detects the vehicle speed and outputs speed data to the microcomputer 50. The rotation sensor 62 detects the rotation speed of the engine and outputs the rotation speed data to the microcomputer 50. The microcomputer 50 drives the stepping motors 13 and 23 and the liquid crystal display 30 based on a predetermined program stored in the ROM 52.

  The liquid crystal display 30 includes a liquid crystal display panel (display panel) 31 formed of a TFT (Thin Film Transistor) type liquid crystal display element, and a light emitting element 32 that transmits and illuminates the liquid crystal display panel 31.

  On the screen 30a of the liquid crystal display 30, an image 71 indicating the remaining fuel, an image 72 indicating the shift position, an image 73 indicating the travel distance, a warning image 74, and the like are displayed. The warning image 74 includes a warning graphic (warning mark) 74a and a warning character (warning mark) 74b, and border portions 74c and 74d.

  The warning graphic 74a is a graphic imitating a vehicle engine and is displayed in red. The warning character 74b is composed of a character string “CHECK ENGINE” and is displayed in red so as to be adjacent to the warning graphic 74a. The border 74c is displayed blinking in white so as to border the warning graphic 74a. The border 74d is displayed blinking in white so as to border the warning character 74b. The border portions 74c and 74d are displayed so that the brightness gradually decreases from the warning graphic 74a and the warning character 74b to the outside. That is, the borders 74c and 74d are displayed so that the brightness gradually increases from the surroundings toward the warning graphic 74a and the warning character 74b, and the outermost lines of the warning graphic 74a and the warning character 74b have the maximum lightness. The background of the warning image 74 is displayed in black.

  FIG. 4 shows a second embodiment. In the second embodiment, only the warning image 75 is different from the first embodiment, and other configurations are the same as those in the first embodiment.

  The warning image 75 includes a warning graphic (warning mark) 75a, a warning character (warning mark) 75b, and borders 75c and 75d. The warning graphic 75a is a graphic imitating a vehicle engine and is displayed in white. The warning character 75b consists of a character string “CHECK ENGINE” and is displayed in white so as to be adjacent to the warning graphic 75a. The border 75c is displayed blinking in red so as to border the warning graphic 54a. The border 75d is displayed blinking in red so as to border the warning character 75b. The background of the warning image 75 is displayed in black.

  According to the first and second embodiments, the occurrence of an abnormality can be quickly recognized by blinking the borders 74c, 74d, 75c, and 75d. Moreover, the visibility of the warning images 74 and 75 is improved by not blinking the warning graphics 74a and 75a and the warning characters 74b and 75b.
