Description

DETAILED DESCRIPTION OF THE INVENTION The present invention collects a plurality of data necessary for driving a vehicle,
The present invention relates to a display device that displays the area on a display panel in which a plurality of display segments each forming a quadrilateral with two opposing sides are provided in the vertical and horizontal directions.

Conventionally, the meters mounted on vehicles include tachometers, speedometers, fuel meters,
There are temperature meters, etc., and these are located near the driver's seat, but if you want to read multiple data at the same time, for example, if you want to read the tachometer and speedometer at the same time, you need to read each meter sequentially. I didn't have to.

In view of these conventional problems, the present invention makes it possible to instantly and accurately read a plurality of data necessary for vehicle travel.
An object of the present invention is to display arithmetic outputs of a plurality of coded data on a display panel in which a plurality of display segments each forming a quadrilateral with two opposing sides are provided vertically and horizontally. The present invention provides a novel display device that displays area continuously from the left and right directions.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a circuit diagram of a display device configured to display the running speed of a vehicle and the rotational speed of an engine. In the figure, 1 is a conventional running speed sensor installed in a vehicle, 2 is a rotational speed sensor, and on the output side of these is an interface circuit 3 for data input that takes in and encodes each speed data. A calculation processing circuit 4 for calculating and distributing each data is connected to the output side thereof. Further, a display panel 5 is connected to the output side of the arithmetic processing circuit 4. This display panel 5 is made up of a plurality of display segments 6 arranged vertically and horizontally in the form of quadrilaterals with two opposing sides that are equal to each other. A speed display scale 7 and a traveling speed display scale 8 are written around the display panel 5. It should be noted that each display segment 6 may be further divided into smaller segments so that detailed data between each of the display scales 7 and 8 can be displayed. In this case, the display scales 7 and 8 Fill in more details.

According to the display device having such a configuration, speed data from each speed sensor is inputted to the input interface circuit 3 as the vehicle travels, converted into a digital code, and inputted to the arithmetic processing circuit 4. The arithmetic processing circuit 4 performs arithmetic operations on each of the digitized data to control the temporal relationship, and is added to the display panel 5 and output to each display segment 6 as data that changes in two axes. Display is performed sequentially and continuously. Panel 5 of the diagram
In this example, the area displayed with diagonal lines indicates that the vehicle's running speed is 122 km/h and the engine speed is 122 km/h.
4000 rpm is displayed, and these two data can be directly read instantaneously and accurately as the value at the position where the contour of the area-displayed portion intersects the horizontal and vertical axes. Note that a shaded area 9 in the display panel 6 is an area that displays the rotational speed of the engine when the vehicle is stopped.

FIG. 2 shows another embodiment of the display panel 5. In FIG. This display panel 5a has a plurality of square display segments 6a arranged in parallel in the vertical and horizontal directions.
Traveling speed scale section 11, fuel display scale section 1
2, temperature display scale section 13, voltage display scale section 14,
As the oil display scale section 15 and other appropriate display scale sections 16 and 17, sensing information corresponding to each of these modes is added to the display panel 5 from the arithmetic processing circuit 4 similar to the above, and continuous and changing data is displayed one after another. can be displayed simultaneously.

In this way, a plurality of pieces of data can be displayed simultaneously and clearly on one compact display panel by varying the display area of the display segment. In addition,
In this case, the display segments 6a can be arranged in different colors to indicate the limit values of each data. Furthermore, light emitting elements such as light emitting diodes can be used as the display segments 6 and 6a, and when a cathode ray tube is used, the number of dots is controlled by the arithmetic processing circuit 4 using a dot crosshatch generator. It is also possible to display data in this manner.

In summary, according to the present invention, data necessary for running the vehicle is input to the interface circuit,
These data are encoded and input into an arithmetic circuit to perform arithmetic processing, and the output is sent to the opposing two
By displaying a plurality of quadrilateral display segments with equal sides on a panel arranged vertically and horizontally, the above-mentioned plurality of data related to vehicle travel can be read instantaneously and accurately. At the same time, since the entire display body can be made compact, the space near the dash board can be used effectively, which not only improves the design, but also shows the area, so the ratio of the above multiple data expressed on the vertical and horizontal axes can be improved. For example, in the above embodiment where the vehicle speed and engine speed are set on the horizontal and vertical axes, respectively,
It has various practical effects, such as being able to easily recognize whether the engine speed is appropriate for the vehicle speed, contributing to engine stall prevention, energy-saving driving, etc.
