1. V sv\u011bt\u011b zobrazovac\u00ed technologie je LCD (Liquid Crystal Display) po des\u00edtky let z\u00e1kladem. Od televizor\u016f a po\u010d\u00edta\u010dov\u00fdch monitor\u016f po smartphony a digit\u00e1ln\u00ed tabule, LCD zobrazovac\u00ed panely jsou v\u0161ude. Na Lynnhan.com, va\u0161em d\u016fv\u011bryhodn\u00e9m dodavateli LED, OLED, LCD, E-Paper displej\u016f a digit\u00e1ln\u00edch tabul\u00ed, jsme zde, abychom vysv\u011btlili, co je to LCD displej, jak funguje a pro\u010d z\u016fst\u00e1v\u00e1 popul\u00e1rn\u00ed volbou pro neespo\u010det aplikac\u00ed.<\/p>\n\n\n\n

Co je LCD displej?<\/h3>\n\n\n\n

2. LCD displej je ploch\u00e1 panelov\u00e1 zobrazovac\u00ed technologie, kter\u00e1 pou\u017e\u00edv\u00e1 tekut\u00e1 k\u0159em\u00edkov\u00e1 \u010d\u00edsla k vytv\u00e1\u0159en\u00ed obraz\u016f. Na rozd\u00edl od star\u0161\u00edch technologi\u00ed jako je CRT (Katodov\u00fd z\u00e1\u0159i\u010d), LCD displeje jsou ten\u010d\u00ed, leh\u010d\u00ed a energeticky \u00fasporn\u011bj\u0161\u00ed. Tekut\u00e1 k\u0159em\u00edkov\u00e1 \u010d\u00edsla v LCD displeji nevyza\u0159uj\u00ed sv\u011btlo p\u0159\u00edmo; m\u00edsto toho se spol\u00e9haj\u00ed na podsv\u011btlen\u00ed (obvykle zalo\u017een\u00e9 na LED), kter\u00e9 osv\u011btluje obrazovku. To d\u011bl\u00e1 LCD displeje flexibiln\u00edmi a vhodn\u00fdmi pro \u0161irokou \u0161k\u00e1lu za\u0159\u00edzen\u00ed, od mal\u00fdch digit\u00e1ln\u00edch hodinek po velk\u00e9 obrazovky TV.<\/p>\n\n\n\n
