    Electrochromic display device employed in a liquid EC system in which an electrode and electrochromic material applied thereon are segmented to define segments corresponding to elements of a displaying pattern and electrode segment portions in excess of the area required to define the displaying pattern are coated with an insulator material, excess area portions of electrochromic material also being similarly coated if necessary, whereby there is reduced build-up of reverse EMF upon activation of the cell and longer color persistence is achieved without use of a complicated drive circuit. To simplify device manufacture for mass-production purposes electrochromic material may be applied in a single layer on an electrode and the display pattern is defined by insulator material applied on selected areas of the electrochromic material.

    (5t) ELECTROCHROMIC INDICATOR
    one
    The invention relates to automation and computing and can be used to display information.
    Electrochromic indicators are known, containing a substrate-base, a flat control electrode that interacts through an electrolyte with electrochromic electrodes attached to a transparent control electrode attached to a transparent cover.
    A disadvantage of the known electrochromic indicators is the instability of the controlled staining, since in them there is a spontaneous erasure of the recorded information.
    Closest to the proposed technical entity is an electrochromic indicator comprising a housing filled with electrolyte and .20 made of a base, face gaskets and a transparent cover in which a flat control electrode, located on the base, is installed, transparent control electrodes 25
    connected to the master circuit and located on a transparent ring, and electrochromic segmented electrodes mounted on transparent control electrodes 2j.
    The disadvantage of this indicator is the gradual dissolution of the electrode in the electrolyte, since the electrodes are usually formed by thin layers of conductive materials.
    The purpose of the invention is to increase the reliability of the device and increase its durability.
    The goal is achieved by the fact that the electrochromic indicator, content-. craving case filled with electrolyte. and made of a base, face gaskets and a transparent cover, in which a flat control electrode is installed, located on the base, transparent control electrodes connected to the driver circuit and located on the transparent cover, and electrochromic segmented electrodes attached on transparent control electrodes, contains a layer of insulating material deposited on transparent control electrodes, with a layer of insulating material located along the periphery uu working surface of each of zlektrohromnyh segmented electrodes. FIG. 1 is a schematic representation of an electrochromic indicator, a plan view; in fig. 2 and 3 is the same cross section (options). The electrochromic indicator comprises a housing filled with electrolyte 1, the housing consisting of a base 2, face gaskets 3 and i and transparent. covers 5. Inside the case on the base 2 there is a flat control electrode 6. On the transparent cover 5 also inside the case there are fixed control electrodes 7, on the inner surface of which electrochromic segmented electrodes 8 are fixed. The end pads 3 and t are arranged so that the end sections the flat control electrode 6 and the transparent control electrode 7 could be connected to an excitation circuit (not shown). A layer 9 of insulating material is applied on the transparent control electrodes 7 and on the end surfaces of the electrochromic segmented electrodes 8. In the proposed electrochromic indicator, transparent control electrodes 7 are made, for example, of indium oxide or tin oxide. The BpOs are formed by spraying or printing on a transparent lid 5 formed of glass, or a transparent plastic plate, or using a film of transparent resin. The transparent control electrodes 7 are divided into segments 7o and / d by etching or other known methods. Segmented electrochromic electrodes 8a and BS are 0.5-1 microns thick, made of vanadium trioxide WO-j or oxide of another transition metal and deposited on each segment of the transparent control electrode 7. Each electrochromic segmented 8q or 86 electrode should completely cover the end face a portion of the etched segment 7a and 76, which is easily achieved by applying electrochromic layers through a mask that creates depressions in the transparent control electrode 7. The material of the insulating layer 9 must react with the electrolyte 1. Silicon oxide SiOj or SiO, or alumina, organic substances, such as epoxy resin, photoresistive material or paints and varnishes, are practically suitable. If the base 2 is made of a sheet of glass, or a transparent plastic, or a transparent film of resin, then the flat control electrode 6 can be made of indium oxide 3, or tin oxide SnOrt. If the base 2 is made of stainless steel sheet, then the flat control electrode can be made in the form of a carbon electrode. The electrolyte 1 used must be stable with respect to the segmented electrode electrodes 8 and the insulating material layer 9. It may contain acetonitrile as a solvent and lithium perchlorate LiCtQj added to a content of 1 mole per liter of electrolyte. In another embodiment, the use of propylene carbide as a solvent creates an advantage, since it allows the indicator to operate in a wider temperature range. A solvent can also be used, which is a mixture of glycerol SLNdO and a saturated solution of tungsten trioxide WOj in 2N. sulfuric acid. If the flat control electrode 6 is made of stainless steel, it is advisable to add a light-scattering material, such as titanium dioxide, to the electrolyte to provide a white background for the contrast of the image on the indicator. The device works as follows. When a potential difference of 1-2 V is applied to control electrodes. moreover, the transparent control electrode 7 or one of its 7cf segments is negative, the portions of the electrochromic segmented electrodes 8 that are in 8 contact with the electrolyte 1 show a blue color. The staining effect can be removed with an erasure potential equal in magnitude but opposite to
