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, ■ is a case in which a circular hole is formed in the surface wall, 2 is a display element disposed inside the case 1 and has a circular display surface 2a, and 3 is a display element installed in the surface hole of the case 1. It is a transparent acrylic board.

Next, the display method will be explained. In the conventional display unit, when the display element 2 displays a display on the display surface 2a having the desired shape, the display state can be seen from the outside through the transparent acrylic plate 3 on the surface of the case 1 having the same shape. This allows the pattern to be displayed.

Conventional display units are configured as described above, and the display pattern is engraved or printed directly on the surface of the case, making it impossible to change the display pattern. Further, since the element pattern (the shape of the display surface) of the display element was the same as or similar to the display pattern, if the display pattern was different, a display element having a display surface of a shape corresponding to the different display pattern was required.

[Summary of the invention]

This invention was made in order to eliminate the above-mentioned drawbacks of the conventional devices, and in addition to forming a wide display surface of a display element, a designed filter having an arbitrary display pattern is removably superimposed on the display surface. It is an object of the present invention to provide a display unit in which it is possible to display various display patterns with a single display element, and the display pattern can be easily changed.

[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 an embodiment of the present invention. In the figure, 1 is a case, 2 is an ECD (electro-chromatic device) which is a display element provided on the surface of the case 1, and whose almost entire surface is formed on the display surface 2b.
mic Display), -4 to 7 are design filters each having an arbitrary display pattern 4a to 7a, and the design filter 4 is placed on the display surface 2b of the ECD 2.
One of the items 7 to 7 is attached freely.

Here, ECD is constructed by disposing a coloring material between a transparent electrode and a counter electrode and filling it with an electrolyte.
It is a non-emissive display element that uses the oxidation/reduction reaction caused by the application of voltage to reversibly change the color of the color-forming material to display images.

Next, the display method will be explained. In this display unit, when the display surface 2b of the ECD 2 develops a color, the color development state can be seen from the outside through the transparent display patterns 4a to 7a of the design filters 4 to 7 superimposed on the display surface 2b. This will display the
At that time, if the design filters 4 to 7 are appropriately selected, a desired pattern can be displayed.

In the display unit of this embodiment as described above, the display pattern can be changed by replacing the design filter, so a single ECD can display various display patterns, and changing the display pattern is also very easy. It is.

Also, since we decided to use ECD, the display surface is thick (
It doesn't require that much power though.

Note that in the above embodiment, a case-shaped display element was described, but this display element may be a mosaic tile.
The same effects as in the above embodiment are achieved.

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, since the display element and the design filter having an arbitrary display pattern are interchangeably superimposed, it is possible to display various display patterns with one element, and the display This provides the effect that patterns can be easily changed.
