| dc.description.abstract | The design of an analog-discrete device is developed. Its feature is the absence of external voltage sources, converters and voltage dividers, and thus protected from leakage of side electromagnetic radiation. Since the electro-optical effects in liquid crystals have a threshold character, this property will lie at the basis of the use of liquid crystals to create indicators with a low level of radiation. These indicators are distinguished by a low power consumption, high reliability, simple design and low cost. The transformation of an electrical signal into an optical counting occurs in a liquid crystal display. This is achieved due to the fact that the reference electro- optical elements are connected with a voltage divider, whose role is performed by a high-level electrode, which is contained inside the indicator. The electro-optical reference elements are formed by mutually penetrating combing electrodes placed on the same glass substrate of the indicator. This greatly simplifies the technology of manufacturing the device, because the thickness of the layer of liquid crystal becomes insignificant and there is no need to strictly withstand it. The measured voltage is applied to contact pads, which are located at the ends of high-level electrode, which acts as a voltage divider. From the divider, the voltage is fed to one part (upper) of the comb electrodes, and to the second part (lower) of the electrodes, mutually penetrating with the help of a low-anode electrode. The topology of electrodes, including comb, is performed by milling fine films with an argon laser. In the study, we found out the criterion of the possibility of constructing a reference device with different degrees of reference, which uses the electro-optical effect in a liquid crystal with threshold voltage. And it has been shown that if such equality is not fulfilled, it is necessary to change the levels of voltage reference. The results of studies and calculations of the device on the twist effect and the effect of dynamic light scattering are presented. The results of experimental studies are quite consistent with the calculations, which testifies to the possibility of practical application of an analog-discrete display unit. | uk_UA |
