Description

DETAILED DESCRIPTION OF THE INVENTION (a) TECHNICAL FIELD OF THE INVENTION The invention relates to the development of a multicolor display element for displaying a display surface in different colors as a display element for a graphic display device or the like.

(b) Technology background One type of mechanically operated display device is a multi-sided display device.

Multi-sided displays are used for specific displays with little information, such as conventional destination display or content display, which are used alone. 2. Description of the Related Art Since there is a demand for a multi-panel display device that can display on a display surface such as a graphic display and adapt to the diversification of information, the development of display elements that are miniaturized and display multiple colors is progressing.

(c) Prior Art and Problems To drive the display surface of a multi-sided display, the display surface is generally rotated to display a predetermined display surface by changing the direction of magnetization of an electromagnet, but the structure of the drive unit is complicated. However, there is a limit to the miniaturization of the device, and the display is generally cylindrical and the display area efficiency of the display window is poor. On the other hand, a display device that transports and moves a large number of polygonal display elements and displays graphics by color-coding and selectively arranging the multiple display surfaces of the display elements is advantageous in increasing its size and can display a wide variety of information. On the other hand, it has many mechanical elements and is not easy to configure.

Moreover, in either case, the viewing angle is narrow and it is not suitable for display in a dark place.

(d) Purpose of the Invention In view of the above points, the present invention incorporates a lamp light source, rotates a triangular prism outer display body and a cylindrical inner display body by motor drive, and overlaps the display surfaces of each display body. The object of the present invention is to provide a display means using subtractive color mixture, and to obtain a display element that is effective in miniaturization.

(e) Structure of the Invention The above-mentioned object according to the present invention is to provide a triangular prism outer display body with one side transparent and the other two sides forming a colored transparent plate, and a colored transparent panel divided into three parts by a flexible partition plate and color-coded. A display element is constructed by incorporating a hollow cylindrical inner display body and a lamp light source, and the outer display body and the inner display body are individually driven to rotate, and the display color of the outer display body and the inner display body are changed. This is achieved by displaying multiple colors through subtractive color mixing with the display body colors.

(f) Embodiments of the Invention Embodiments of the invention will now be described in detail with reference to the drawings. FIG. 1 is a perspective view showing a display element according to an embodiment of the present invention, FIG. 2 is a perspective view showing a drive system, and FIG. 3 is a plan view showing the Fi display element. A hollow cylindrical inner display body 2 is housed within an external display body 1 having the shape of a triangular prism, and a lamp 3 is built therein. The A side la, the B side lb, and the C side 1ci of the outer display body 1 are each used as a display surface. For example, the A side 1a is a transparent plate, and the B side lb and C side IC are colored transparent plates. Each display surface is obtained by rotationally driving a gear 4 provided on the bottom surface of the outer display panel 1 via a motor 5. A flexible partition plate 6 made of, for example, a rubber sheet is attached to the inner display body 2 so as to divide the outer periphery of the cylindrical portion into three parts as shown in the figure. Each cylindrical area divided into three is used as a display surface, and A' surface 2a,
The B' plane 2b and the C' plane 2c. In this case A′ face 2a
The white 37 surface 2b and the C' surface 2C are colored and transparent. ○Each display surface has a gear 8 attached to the shaft 7 attached to the bottom of the inner display board 2 and is driven by a motor 9 to obtain a predetermined display surface. Therefore, the outer display body 1 and the inner display body 2 are configured to be rotated by independent drive systems to obtain a predetermined display surface.

The partition plate 6 of the inner display body 2 is colored to match the same display color as each display surface, but it is suitable to use an aluminum-based paint containing aluminum particles, which has good reflection efficiency. FIG. 3 is a diagram for explaining a display procedure that is an example.

In (1), if the display surface is the input direction of the outer display 1, the display surface of the outer display 1 is the A side, and the inner display 2 is the display surface of the outer display 1, as shown in the figure.
There are six display screens and subtractive color mixture is used. This display element is displayed at night, for example, and the outer display body 20B
When it is desired to display the display surface, the display surface of the inner display body 2 needs to be an a-plane display with a white display body color. The display body is rotated to obtain this display surface. First, the outer display body 1 is rotated counterclockwise to move the B side to the display surface, and the inner display body 2 is rotated clockwise to stop the rotation of the 8th side to the display surface, thereby displaying one screen and displaying the lamp 3. A desired display can be obtained by lighting the . The partition plate 6 of the inner display body 2 is attached to the cylindrical inner display body 2 using flexible and highly elastic silicone rubber or the like in order to rotate and slide on the inner surface of the outer display body 1. To install it, as shown in FIG. 5, a groove 10 is formed in the cylindrical portion of the inner display body 2, and the partition plate 6 is inserted and fixed by adhesive. Further, the positioning of the display surface can be selectively achieved by applying a predetermined rotation by driving a pulse motor. In this embodiment, the outer display body 1 is rotated counterclockwise, and the inner display body 21 is rotated clockwise, but it goes without saying that it may be rotated in either direction. By using such a display element, it is possible to create multiple colors by subtractive color mixing by overlapping the display surfaces of the outer and inner display bodies.

For example, the display surface of the outer display body 1 may be transparent or colored transparent (red).

If the display surface of the inside display body 2 is made of white, blue, green, etc., the display colors shown in the following table can be obtained.

In this way, it is effective to obtain a graphic display device by using a large number of 9 display elements capable of displaying 9 colors.

(g) Effects of the Invention As explained in detail above, the display element of the present invention has the great effect of being advantageous for miniaturization and enabling multicolor display without reducing display area efficiency.
