DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display element, and more particularly, to a display element having a number display section composed of a plurality of segments arranged in the shape of a sun.

[0002]

2. Description of the Related Art Conventionally, there is a liquid crystal display element 2 having a number display section 1 comprising a plurality of segments a to g (FIG.
reference). The liquid crystal display element 2 is provided with four sets of numeral display units 1, and these numeral display units 1 display four-digit numbers. As shown in FIG. 6, the numeral display section 1 is composed of seven segments a to g arranged in the shape of a date, and the numerals are displayed by appropriately setting each of the segments a to g to a transparent state or a non-transparent state. I do. For example, when the liquid crystal display element 2 is of a positive display type, "4" is displayed by making the segments b, c, f, and g non-transmissive and making the segments a, d, and e transparent. reference).

[0003]

The above-mentioned numeral display section 1
Has the advantage that "0" to "9" can be displayed with a small number of segments a to g. However, the numbers displayed in the segments a to g of the number display unit 1 are not numbers having beautiful contours as shown in FIG. For example, the right central part 3 of the numeral display unit 1 is preferably a round outline when displaying “2”, “5”, and “6”, while the right central part 3 is a contour having two obtuse angles. Has become. The lower left corner 4 of the numeric display 1 is "0", "3",
When displaying "5", "6", "8", and "9", it is desirable to use a round outline, and when displaying "2", it is preferable to use an acute outline. It has an outline. Further, “1” and “7” displayed in the segments a to g of the numeric display section 1 have a contour having two triangular constrictions at the right center position 3. Also, "0"
Has such a contour that the right center part 3 and the left center part 5 are confined. The present invention provides a display element having a number display section capable of displaying a number with a beautiful contour.

[0004]

In order to solve the above-mentioned problems, the present invention provides a display element having numeral display portions 8 , 9 for displaying numerals by a plurality of segments arranged in the shape of a date.
6 , segments G and P surrounded by two first outlines formed of outwardly convex curves and one second outline formed of straight lines are represented by Right center part 11
And at the center 12 on the left .

[0005]

DETAILED DESCRIPTION OF THE INVENTION, the numeral display unit 8,9, one consisting of two first outline and the straight line of the form of the convex curved outwardly disposed right center point 11 and the left central point 12 The segments G and P surrounded by the second outline are provided.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to a liquid crystal display element used for a vehicle instrument will be described below with reference to the accompanying drawings. FIG. 1 is an explanatory view of a numeral display section, and FIG. 2 is a front view of a liquid crystal display element.

Reference numeral 6 denotes a liquid crystal display element, and the liquid crystal display element 6 is of a negative display type. The liquid crystal display element 6 displays the speed of the vehicle and the like.
And a bar graph 10 having an arc shape. Numeric display 7
Can display “1”, and the number display sections 8 and 9 can display “0” to
"9" can be displayed. The bar graph is composed of a number of segments arranged in a row, and the speed is displayed by a bar that expands and contracts according to the speed (ie, a segment in a transparent state).

As shown in FIG. 1, the numeral display sections 8 and 9
It consists of 21 segments A to U arranged in the shape of a sun, and includes an upper horizontal band portion composed of segments A to D,
Right vertical band consisting of segments EK, segment L,
M has a lower horizontal band composed of segments NT, a left vertical band composed of segments N to T, and a middle lateral band composed of segments U. As shown in FIG. 3, the numeric display units 8, 9 display “0” to “9” by appropriately setting each of the segments A to U to a transparent state or a non-transparent state. As described above, the liquid crystal display element 6 is of a negative display type, and the numerals are displayed in the color of light transmitted through the liquid crystal display element 6, but in FIG. 3, the numerals are shown in black. .

The right central part 11 and the left central part 12 of the numeral display parts 8 and 9 have inwardly convex portions facing the outer lines formed of outwardly convex curves of the segments F, G, I, O, P and R, respectively. Segments F, H, I, O,
Q and R are provided, right center point 11 and left center point
12 can display a round outline. For example, as shown in FIG. 4, the right center portion 11 has outer lines H1 and I1 formed of inwardly convex curves opposed to outer lines F1 and G1 formed of outwardly curved segments F and G, respectively. Segments H and I
When segments "2" are displayed, the segments F and G are set to the transparent state and the segments H and I are set to the non-transmissive state, so that a rounded contour projecting obliquely downward to the right can be displayed. In addition, segments F and H having outer lines F2 and H2 each having an inner convex curve opposed to outer lines G2 and I2 each having an outward convex curve of the segments G and I are provided. When “6” is displayed, by making the segments G and I transparent and the segments F and H non-transparent, it is possible to display a round outline that is diagonally upper right and convex.

The upper right corner 13,
The lower right corner point 14, the lower left corner point 15, and the upper left corner point 16 include an outer line formed by an inwardly convex curve facing the outer line formed by the outwardly convex curves of the segments C, J, L, S, and a straight line. Segments D, K, and
M and T are provided, and a round outline and a corner outline can be displayed. For example, a segment M is provided at the lower left corner point 15, and when displaying "2", the segments L and M are displayed.
By displaying in a transparent state, an outline of an acute angle is displayed,
When “0”, “3”, “5”, “6”, “8”, and “9” are displayed, a round outline can be displayed by setting the segment L to the transparent state and the segment M to the non-transparent state.

[0011] Segments G, H, P, and Q surrounded by three outlines are provided at the right center portion 11 and the left center portion 12 of the numeric display portions 8 and 9, respectively. H
Are in a transparent state when displaying "0", "1", and "7", and the segments P and Q are in a transparent state when displaying "0". Can be displayed without numbers.

According to the above-described embodiment, by forming the number display sections 8 and 9 with the segments A to U, it is possible to display numbers having beautiful contours. In this embodiment, the present invention is applied to the liquid crystal display element 6, but the display element may be, for example, a fluorescent display tube (VFD).

[0013]

According to the present invention, there is provided a display element having a number display portion for displaying a number by a plurality of segments arranged in the shape of a date, wherein two first external shapes each having an outwardly convex curve are provided. A segment surrounded by a line and one second outline formed of a straight line is referred to as a right center portion and a left center portion of the numeral display portion.
It is provided in the place and can display numbers with beautiful outlines.
