segments and any of the light or combination of Yet a further embodiment comprises a display system wherein the seven segments of the digi tal play are light three light bulbs of the colors blue and green being provided behind the light means being provided for actuating any desired combination of the light valves of the seven segment valve wi th the tion of one or more of the colored light There are known various digi tal display devices which provide a sharpy hi numeric These known incandescent devices permi t the use of fil ters to obtain a display of any desired It is that once the color of the filter is the color can only be changed by the change of the filter in front of the display I t i s clear that dual segments of such devices may be addressed to provide symbol or alphabe ti c such as le The known digi tal display devi ces compri se seven segments of The present invention provides a possibility to present a variety of The human memory for various and thus it is easy for a person to remember and assiociate a tain color with a certain By indicating certain meaeu in varying and distinct it is possible to use one indicating mechanism for indicating information relating to The color indicates in this case the kind of the digits appearing by means of the digital display device indicate the quantity associated with the given For it is easy to associate a certain color with each of the multiplication and when the result the color confirms that the correct operation has been carried As further the same indicator panel may be used for cating varying as for example each of these being associated with a given seven distinct colors being According to the it is thus possible to convey by one numerical display device seven times the information veyed by a conventional device of this According to the present a similar device is the difference being the provision of three parallel incandescent wires instead of each of the seven incandescent wires of the conventional a composite color filter of the three basic red and green being one color in front of each of the three parallel incandescent means being provided for actuating any combination of the

leads to the wires 12 and are designated by numerals 15 and the color filter comprises a blue middle section and two adjacent sections and of green and red In front of the color filter there is provided a frosted screen of glass or plastic On the frosted either on its front or its back or in close vicinity of there is provided a mask which is This mask of the seven segments and the width of each of these sections is preferably less than the width of the three colored sections of colored The provision of the narrow transparent strips in front of the colored filter results in sharp and clear image of the dea red when one or more of the wires are The entire assembly is encased in a glass bulb which may flat in front of the display the wires being held in posi tion by means of the support member As shown in wi th respe ct to two groups of three each there i s provided a common lead 23 for each group of wi res II and and one common lead and respectively for each of the three there is vided a total of seven common leads 23 as E for each of the seven wire groups and three common leads for each the color By means of these i t i s possible to obtain a display of of the desired figures 0 to and each of the figures may be obtained in a desired by actuating the wires located behind the color filter a red display i s by that behind a blue one behind 17 a green one the simultaneous actuation of red and green a yellow all three whi te In actual practi ce and for a size of about that of di splay the three parallel wires are spaced at a distance of about I mm eech the distance from the wi re to filter in front of it being about I the di stance from the color filter to the frosted screen and mask in front of same being of the same order of magni tude The width of the parallel colored strips compri sing the fil ter i s also about I mm for each the of the Due to geome tri c configuration of the color fil the light emanating from any portion thereof is projected onto the frosted screen in front of the mask resul ting in the desired mixed non transparent mask result a sharp and bright image of desired color and intensi According to a modification of the present there may be used instead of the wi res and the corresponding a combination of three di fferently colored light emitting diodes red blue and in the form of narrow parallel close to each other
