The institute was run from 1980 to 1989 by the USSR Ministry of Communication Techniques and the Ukraine Academy of Sciences for the following purposes:

Since the disintegration of the Soviet Union, the institute and the Korolyov Industrial Corporation have been trying to reorient their efforts towards civil applications of both LC and EL devices that can be used, for example, in avionics. The corporation has all of the facilities needed to produce LC indicators and EL devices, but domestic financial resources are currently insufficient.


The institute has a department of LC and EL displays, with 35 staff members; a few years ago there were 150 people on the staff.

Equipment includes: (a) two clean rooms purchased in Japan two years ago (class 1,000, area 220 m2, and class 10,000, area 320 m2), which are at the installation stage; and (b) lines for manufacturing liquid crystal and electroluminescent indicators, equipped with all facilities for chemical treatment, photolithography, vacuum deposition, heat treatment, mounting, and control.

The institute's production capacity is 10,000 LC segment indicators per year.

Liquid Crystal Indicators

Six types of LC segment indicators based on TN cells have been developed in the institute. The coating consists of ITO conducting material and polyimide for orientation of liquid crystal. Azimuth orientation is provided by the brush rubbing technique. LC materials are provided by the Monocrystal Institute (Kharkiv). The size of the indicator is 80 x 120 lines (80 mm2 x 100 mm2). The operating voltages are 3-4 V.

The technology of the ITO deposition on the polymeric (thermally unstable) substrate has been developed. The maximal size is 30 cm2 x 30 cm2. The surface coating (thickness 800 ) is transparent in the visible and IR parts of the spectrum (90% of the intensity); surface resistance is less than 100 Ohm/ģ. These coatings can be used also as antistatic coatings for polymeric optical details.

The technology is developed also for coating that is transparent (>85%) in the range from 0.4-20 mm. The substrate should be thermally stable (melting temperature approx. 250-350 degrees centigrade). The development of matrix LC indicators (80 x 120 pixels, size 60 mm2 x 86 mm2, and 120 x 160 pixels, size 90 mm2 x 115 mm2) and of color matrix LC indicators have been started.

EL Devices

The material is ZnSMn (yellow color). The number of pixels are 40 x 56 (size 38 mm2 x 54 mm2); 32 x 64; 128 x 168 (78 mm2 x 100 mm2); 256 x 256 (140 mm2 x 140 mm2). The lifetime is 2,000 hrs. The problem is to reach 10,000-15,000 hours using pure materials. In the past it was possible to purchase these pure materials from Zelenograd (Russia). In Ukraine the source of the pure materials is located in Odessa.

EL indicators have rigid vibro-stable construction. The temperatures range from -50 to 80 degrees centigrade. The institute sells these indicators to the Antonov industry complex, Kyyiv, where the indicators are used in avionics (they are stable and it is not necessary to provide high information density). The price of one indicator is $60-70.

Basic technical parameters of the EL indicators are as follows:


The institute has a well-developed program in traditional LCD and ELD technologies. The manufacturing process is based mainly on Ukrainian materials. Collaboration with other centers in Ukraine and abroad can result in successful manufacturing of LC- and EL- based devices. The institute is seeking ways to establish cooperation with U.S. companies.
