Abstract

PROBLEM TO BE SOLVED: To provide a display device having a display part capable of displaying with a color other than black. SOLUTION: The display device is provided with a fixed display part 13 consisting of letters, figures, or marks, or the like on a display board 9, and a liquid crystal display element 10 having a segment 18 in the place corresponding to the fixed display part 13 is arranged in front of the display board 9. The segment 18 of the liquid crystal display element 10 is made to be changed over from a transmittable condition to a nontransmittable condition, and vice versa. When the segment 18 is made to be the nontransmittable condition, the fixed display part 13 of the display board 9 becomes invisible, and when the segment 18 is made to be in a transmittable condition, the fixed display part 13 is displayed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a display device, and more particularly to a display device having a liquid crystal display element.

[0002]

2. Description of the Related Art Hitherto, various display devices using liquid crystal display elements have been proposed. For example, there is a speed display device for displaying the speed of a motorcycle (see FIG. 6). The liquid crystal display element 2 of the speed display device 1 has a liquid crystal cell in which liquid crystal is sealed between a pair of transparent substrates 3 and a polarizing plate (not shown) attached to both front and rear surfaces. The liquid crystal display element 2 has a number display section 5 composed of a plurality of segments 4 for displaying numbers, and a unit display section 7 composed of a plurality of segments 6 for displaying a unit of speed. The segment 4 is arranged in the shape of a date, and the numeral display unit 5 can display the numerals 1 to 9 by appropriately setting the segment 4 to an opaque state.

[0003]

However, the display units 5 and 7 cannot be displayed in colors other than black, and the liquid crystal display element 1 has a problem that various displays cannot be performed. That is, when the segments 4 and 6 are in the opaque state, the display units 5 and 7 are displayed in black. For example, the numeric display unit 5 and the unit display unit 7 are displayed in different colors, or the display units 5 and 7 are displayed in different colors. 7 cannot be displayed in a color other than black. The present invention has been made in view of the above problems, and provides a display device having a display unit that can display a color other than black.

[0004]

The display plates 9 and 21 are provided with fixed display portions 11 and 22 having at least eight characters, and the liquid crystal display device 10 has a plurality of segments 17 at locations corresponding to the fixed display portions 11 and 22.
Are disposed in front of the display boards 9 and 21. The segment 17 of the liquid crystal display element 10 can be switched between a transmissive state and a non-transmissive state, respectively, and a number is displayed by appropriately setting the segment 17 to a transmissive state or a non-transmissive state.

[0009]

An embodiment of the present invention will be described below with reference to the accompanying drawings. 1 to 3 show the first embodiment.

Reference numeral 8 denotes a speed display device, which has a display panel 9 and a liquid crystal display element 10 disposed in front of the display panel 9. The display plate 9 is formed by printing fixed display portions 11, 12, 13, and 14 on the surface of a transparent resin substrate (for example, a polycarbonate substrate). The fixed display portion 11 is composed of orange 1 and 8 characters. The fixed display section 12 is composed of white characters and symbols, and displays a unit of speed. The fixed display sections 13 and 14 are each composed of yellow characters and graphics. Reference numeral 15 denotes a black portion, which is printed on the surface of the display panel 9 excluding the fixed display portions 11, 12, 13, and 14.

The liquid crystal display element 10 has a structure in which a nematic liquid crystal is sealed between a pair of transparent substrates 16 and a polarizing plate (not shown) is attached to both front and rear surfaces of the liquid crystal cell. The liquid crystal display element 10 includes a segment 17 arranged in the shape of a sun at a location corresponding to the fixed display section 11, and rectangular segments 18 and 19 arranged at locations corresponding to the fixed display sections 13 and 14, respectively. (See FIG. 2).

The speed display device 8 can display a numeral by appropriately setting the segment 17 in a transparent state or a non-transparent state. For example, as shown in FIG.
By properly setting 17 to a non-transparent state, a numeral 30 can be displayed (see FIG. 3). In addition, the speed display device 8 can display the fixed display portions 13 and 14 by setting the segments 18 and 19 to the opaque state, making the fixed display portions 13 and 14 invisible, and setting the segments 18 and 19 to the transparent state respectively. For example, as shown in FIG. 1, the fixed display section 13 can be made invisible by making the segment 18 non-transparent, and the fixed display section 14 can be displayed by making the segment 19 transparent (see FIG. 3).

According to the above-described first embodiment, an orange numeral can be displayed by appropriately setting the segment 17 to a transparent state or a non-transparent state. Also, segment
The fixed display sections 13 and 14 can be set by making the 18 and 19 opaque.
Is invisible, and the segments 18 and 19 are made transparent so that the yellow fixed display sections 13 and 14 can be displayed.

FIGS. 4 and 5 show a second embodiment. The liquid crystal display element 10 is the same as that of the first embodiment.

Reference numeral 20 denotes a rotation speed display device, which has a display panel 21 and a liquid crystal display element 10 disposed in front of the display panel 21. The display plate 21 is fixed on the surface of the resin substrate.
3, 24 are printed. The fixed display section 22 is composed of orange figures of 8 and 0. Fixed display unit 23
Is composed of white characters and indicates the unit of the number of rotations. The fixed display section 24 is formed of a yellow figure. Reference numeral 25 denotes a black portion, and the black portion 25 is formed by printing on the surface of the display plate 21 excluding the fixed display portions 22, 23, and 24.

The number-of-revolutions display device 20 can display a number by appropriately setting the segment 17 to a transparent state or a non-transparent state. For example, as shown in FIG. 4, by making the segment 17 appropriately opaque, a numeral 2560 can be displayed (see FIG. 5). In addition, the rotation speed display device 20
Can make the segment 19 opaque, make the fixed display unit 24 invisible, and make the segment 19 transparent, and display the fixed display unit 24. For example, the fixed display unit 24 can be made invisible by making the segment 19 in an opaque state as shown in FIG. 4 (see FIG. 5).

According to the above-described second embodiment, orange numbers can be displayed by appropriately setting the segment 17 to a transparent state or a non-transparent state. Also, segment
The fixed display portion 24 can be made invisible by setting the 19 to the opaque state, and the yellow fixed display portion 24 can be displayed by setting the segments 18 and 19 to the transparent state. Further, the liquid crystal display element 10 of the first and second embodiments does not have the unit display section 12 as described in the conventional example, and the same liquid crystal display element 10 as the speed display device 8 and the rotation speed display device 20 is used. Can be used.

As in the first and second embodiments, it is desirable to provide a black portion 15 around the fixed display portions 11, 12, 13, 14, 22, 23, 24 of the display plates 9, 21. The opaque segments 17, 18, and 19 can be made inconspicuous. In addition, it is sufficient that the color is not particularly black but a dark color, or when the color of the polarizing plate is used as the ground color, the color may be the same as this color. If desired, a light source such as a cold cathode fluorescent lamp may be provided behind the display plates 9 and 21.
By printing 12, 13, 14, 22, 23, and 24 in a transparent color, illumination display of the fixed display units 11, 12, 13, 14, 22, 23, and 24 can be performed.
