Выданы рекомендации для выбора частоты LED-подсветки, сведения видимых мельканий до минимального уровня, использования постоянного тока питания светодиодов. Разработан комбинированный драйвер для питания LED-подсветки.</p></abstract><trans-abstract xml:lang="en"><p>The analysis of control methods for LED backlighting of display devices is carried out. An analysis of the perception of pulsed light sources by human vision is given. Recommendations are given for choosing the frequency of LED-backlighting, information of visible flickering to the minimum level, the use of a direct current of LED power supply. A combined driver for powering the LED backlight is developed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>LED-подсветка</kwd><kwd>светодиодная подсветка</kwd><kwd>жидкокристаллический дисплей</kwd><kwd>ШИМ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>LED backlight</kwd><kwd>liquid crystal display</kwd><kwd>PWM</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">Бугров, В.
