LCD npo

LCD (Liquid Crystal Display) yog ib lub cuab yeej tso saib uas siv cov thev naus laus zis tswj kev xa tawm ntawm cov kua siv lead ua kom pom xim tau zoo. Nws muaj qhov zoo ntawm qhov me me, lub teeb yuag, txuag hluav taws xob, tsis muaj hluav taws xob, thiab yooj yim nqa mus los, thiab siv dav hauv TV, monitors, laptops, tablets, smartphones thiab lwm yam teb.Tam sim no ntaucov tuam txhab ua tau zoo hauv TV teb.

LCD tau pib tsim nyob rau xyoo 1960. Xyoo 1972, S.Kobayashi hauv Nyiv Pooj tau ua qhov tsis zoo thawj zaug - tsis muaj qhov tsis zooLCD npo, thiab tom qab ntawd Sharp thiab Epson hauv Nyiv Pooj tau ua lag luam rau nws. Thaum xyoo 1980s, Nyiv Pooj tau ua tus tswv ntawm cov thev naus laus zis tsim khoom ntawm STN - LCD thiab TFT - LCD, thiab cov kua - siv lead ua kua tau pib tsim kho sai. Tom qab ntawd, Kaus Lim Qab Teb thiab Taiwan, Tuam Tshoj kuj tau nqis tes ua lag luam no. Nyob ib ncig ntawm xyoo 2005, lub teb chaws Suav tau ua raws li. Xyoo 2021, qhov ntim tsim khoom ntawm cov ntxaij vab tshaus LCD Suav tau tshaj 60% ntawm qhov ntim xa khoom thoob ntiaj teb, ua rau Tuam Tshoj yog thawj zaug hauv ntiaj teb.

Cov LCDs tso saib cov duab los ntawm kev siv cov yam ntxwv ntawm cov kua siv lead ua kua. Lawv siv cov kua siv lead ua kua ntawm ob yam khoom siv polarizing. Thaum lub zog hluav taws xob hla dhau cov kua, cov kua siv lead ua tau rov ua dua kom ua tiav kev thaij duab. Raws li kev siv thiab cov ntsiab lus tso saib, LCDs tuaj yeem faib ua ntu - hom, dot - matrix cim - hom thiab dot - matrix graphic - hom. Raws li cov qauv lub cev, lawv tau muab faib ua TN, STN, DSTN thiab TFT. Ntawm lawv, TFT - LCD yog cov khoom siv tso saib tseem ceeb.
