Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a display unit used for monitoring various plants.

[Prior art]

A conventional device of this type is shown in FIG. In the figure, 1 is the case body, 2 is a plurality of cells arranged vertically on the side wall of the case body 1.
It is an LED display element.

Next, the operation will be explained. In the conventional display unit, when a drive circuit (not shown) built into the case body 1 receives an external signal, it lights up a plurality of LED elements 2 attached to the case body 1 one by one from the bottom. By changing the lighting state at this time, a movement display from the bottom to the top, that is, a dynamic display is performed.

Conventional display units are configured as described above, and if the front pattern differs, a corresponding number of display elements is required, and the layout of the display elements is also required, and in this case, it is difficult to assemble the elements. However, there was a drawback that the finish was not necessarily good.

[Summary of the invention]

This invention has been made in order to eliminate the drawbacks of the conventional ones as described above, and includes one of a plurality of design filters having different display patterns configured to be removably attached to the display body. The display surface is constructed by arranging a plurality of unit display elements each having a strip-shaped display surface in a direction perpendicular to the longitudinal direction thereof, and further, the longitudinal dimension of the element is larger than the longitudinal dimension of the element of the design filter. The purpose of this setting is to enable dynamic display of various display patterns with one type of display body, and to provide a display unit that is easy to assemble and has a high degree of completeness.

[Embodiments of the invention]

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

2 and 3 show a display unit according to one embodiment of the invention. In the figure, 1 is case, 3
is a plurality of ECDs, which are display elements, provided on the surface of case 1 and arranged in the vertical direction shown in the figure.
(Electrochromic Display) 4, and the display surface of each ECD 4 is formed into a band shape. 5 to 7 are each arbitrary display pattern 5
One of the design filters 5 to 7 is removably attached to the display surface of the display body 3.

Here, ECD is constructed by disposing a color-forming material between a transparent electrode and a counter electrode and filling it with an electrolyte.The color of the color-forming material is reversibly changed by oxidation and reduction reactions caused by voltage application. This is a non-emissive display element that uses this change to display information.

Next, the display method will be explained.

In this display unit, the display body 3 is colored one element at a time from top to bottom or from bottom to top, and the state of color development is determined by design filters 5 to 5.
7 can be seen from the outside through the transparent display patterns 5a to 7a, thereby creating an optical illusion as if the display is changing with the various patterns 5a to 7a printed on the design filters 5 to 7. For example, the display patterns 5a to 7a of the design filters 5 to 7 shown in FIGS. 2 and 3 express an aquarium, a water surface, and bubbles, and by combining the design filters 5 to 7 and the striped pattern display 3, , it is possible to display changes in the water surface.

In the display unit of this embodiment as described above, the display pattern can be changed by converting the design filter, so it is possible to dynamically display various display patterns with one type of display body. Changing the display pattern is also very easy, and as a result, costs can be reduced, and the finish is good and the degree of completion is high. Also, since it uses an ECD, it does not require much power even if the display screen is large.

Although the above embodiment describes a dynamic display of the water surface, the present invention can be similarly applied to an instrument display such as a bar graph, and in this case as well, various measurement displays are possible as in the above embodiment. Further, the display element may be a display element other than ECD. Furthermore, the design filter may be a film-like filter, and in this case, parallax (pattern shift) due to the thickness of the design filter can be minimized and visibility can be eliminated.

〔Effect of the invention〕

As described above, according to the present invention, one of a plurality of design filters having different display patterns is configured to be removably attached to a display body, and the display surface of the display body is formed into a plurality of units having strip-shaped display surfaces. Since the display elements are arranged in a direction perpendicular to the longitudinal direction thereof, and the longitudinal dimension of the elements is set larger than the longitudinal dimension of the design filter, even one type of display body can be used easily. It is possible to dynamically display various display patterns, and it is easy to assemble, is inexpensive, and has a high degree of completeness.
