К сожалению, создание гребенки металлических электродов усложняет и удорожает технологический процесс и вызывает ухудшение контрастности изображения. В то же время экспериментальные результаты и расчеты, основанные на классической электрооптике кристаллов, свидетельствуют, что электрооптическое переключение в режиме IPS является естественной и неотъемлемой особенностью обычной (со сплошными электродами) дисплейной ячейки с планарно-ориентированным слоем сегнетоэлектрического жидкого кристалла (СЖК), в котором реализуется эффект деформированной электрическим полем спиральной наноструктуры СЖК (DHF-эффект). В такой ячейке переориентация главной оптической оси под воздействием слабого электрического поля тоже происходит в плоскости подложек, если СЖК имеет малый шаг (около 100 нм и менее) и большой угол наклона молекул в слое (около 38 ° и более). Измеренные в данной работе зависимости коэффициента пропускания света СЖК-ячейкой подтвердили достижение электрооптического режима IPS в ячейке DHF СЖК, причем частота модуляции света составила 1 кГц. Таким образом, при сохранении всех достоинств IPS-режима, известных в НЖК, реализация его в СЖК позволяет дополнительно получить технологические преимущества и многократный выигрыш в частоте модуляции.</p></abstract><trans-abstract xml:lang="en"><p>In a known display cell with the nematic liquid crystal (NLC) and interdigital electrodes on one of the glass substrates, the “In-Plane Switching” (IPS) mode is implemented, in which the NLC main optical axis reorients in a plane parallel to substrates, providing the most correct color reproduction at different angles view, up to 178 ° horizontally and vertically. Unfortunately, the creation of interdigital metal electrodes complicates and increases the technological process cost and causes a decrease in image contrast. At the same time, experimental results and calculations based on classical electro-optics of crystals indicate that electrooptical switching in the IPS mode is a natural and intrinsic feature of a conventional (with continuous electrodes) display cell with a planar-oriented layer of the ferroelectric liquid crystal (FLC), in which the effect of the deformed (by the electric field) helix FLC nanostructure is realized (DHF effect). In such a cell, the reorientation of the main optical axis under the influence of a weak electric field also occurs in the substrate plane if the FLC has a small pitch (about 100 nm or less) and a large tilt angle of molecules in the layer (about 38 ° or more). The dependences of the FLC cell light transmittance measured in this work, confirmed the achievement of the IPS electro-optical mode in the DHF FLC cell; moreover, the light modulation frequency was 1 kHz. Thus, while maintaining all the advantages of the IPS mode known in NLC, its implementation in FLC allows additionally obtaining technological advantages and multiple increase in modulation frequency.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>IPS</kwd><kwd>переключение главной оптической оси</kwd><kwd>сегнетоэлектрический жидкий кристалл</kwd><kwd>электрооптический эффект деформированной спиральной наноструктуры</kwd></kwd-group><kwd-group xml:lang="en"><kwd>IPS</kwd><kwd>main optical axis switching</kwd><kwd>ferroelectric liquid crystal</kwd><kwd>crystal-optical effect of deformed spiral nanostructure</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Oh-E M., Kondo K.
