Nguwena ongazikhethela.

LCD TV

Kuyini esibukweni LCD? Lokhu-matrix ehlanganisa amachashazi. Lezi zici (amachashazi) Abizwa ngama-pixel. A-pixel elingu - lokhu sub-Amaphikseli imibala abomvu, aluhlaza okwesibhakabhaka. izakhi Ngaphakathi kukhona zinhlayiya ketshezi, ekushintsheni ilungiselelo ayo emkhakheni kagesi. Ukuze-matrix kukhona kwasemuva. Lapho ezihambayo zinhlayiya kuzovimba noma badlulisele ukukhanya okuvela kulezi izibani. Isibani qinile ngcono umbala, kodwa amandla, ngokulandelana, ngenhla.

Kodwa ukuze kutholakale lotawulungisa okuyinto TV kungcono, LCD noma "plasma", cabangela-plasma TV.

"Plasma"

Plasma isikrini - kuyinto-matrix, owawubumba is e weJiyomethri amaseli. Amaseli zigcwele Xenon noma neon. Okwamanje lapho zithonywa amandla kagesi, igesi ibe plasma bese likhipha ultraviolet. Phezu kodonga cell camera yenziwe ngohlobo olukhethekile, futhi nabo misebe, kuye ngokuthi ukwakheka kwe-ungqimba, sithola umbala oyifunayo. Uma voltage lingaphezulu, iseli ovuthayo licace. Ngokuxuba imibala eyinhloko etholakala ngokuzikhandla ezihlukahlukene shades. Isithombe esikrinini esenzelwa ngu-module electronic, voltage elawulwa oscillator. I plus main - "plasma" kathathu licace kakhulu LED futhi LCD. Luhle ikamelo elikhulu. Ngakho sekuyisikhathi ukunquma ukuthi iyiphi TV kungcono, LCD noma "plasma", wena, yini evumelana nawe best.
