Izibhebhe, iphaneli flat, kanye nokubonakala
Ukuthenga ithelevishini kungakhungathekisa uma ungazi ukuthi yini oyifunayo. Ukusuka emathinini kuya eplasma, kunezibonelo eziningi ezitokisini zesitolo kunezingubo zomagazini. Ngaphambi kokuhlola i-analog ne-digital, i-SDTV, i-HDTV, ne-EDTV, ubuke izinhlobo zethelevishini emakethe yabathengi yanamuhla. Nasi uhlu lwamathelevishini ozothola ezitolo ngaphesheya kweNyakatho Melika.
Ukubuka okuqondile - Ishubhu
Eyaziwa nangokuthi umbono oqondile, ithelevishini yesikhulumi yinto esondelene kakhulu neyodwa yezingane ezibukele lapho beyizingane. Idivaysi efanekiselwayo iyishubhu ye-cathode ray, okuyi- tube ekhethekile yokuphumula . Yonke isayensi eceleni, i-CRTs ifika kuzo zonke izinhlobo nobukhulu kuze kube ngu-40-intshi. Zibonisa isithombe esihle kuzo zonke izingalo, izinga elimnyama elimnyama, futhi liphansi kakhulu kunamanye ama-TV. Naphezu kokwakhiwa kwawo okunamandla nesindayo, amathelevishini e-tube ahlala isikhathi eside futhi ahlonishwa ngokugcina isithombe esihle kuyo yonke impilo yayo, okungaba amashumi eminyaka.
I-Digital Light Processing Processing (DLP)
I-Digital Light Processing yenzelwe ngo-1987 yi-Texas Instruments. Ibizwa ngokuthi ikhono layo lokucubungula ukukhanya kwedijithali ngokusiza kwe-semiconductor ye-optical ebizwa ngokuthi i-Digital Micromirror Device noma i-DMD chip. I-chip ye-DMD iqukethe izibuko ezingaphezu kwesigidi. Ubukhulu besibuko ngasinye singaphansi kwe-1/5 "ububanzi bobunwele bomuntu. Njengamanje, abakhiqizi abangaphezu kwamashumi amahlanu bakhiqiza okungenani oyedwa imodeli yethelevishini ye-DLP. I-DLP ifika ngemuva kokubheka kwangaphambili nangaphambili. Akunakukwazi ukushisa, kodwa abanye abantu bayabona i-glitch ebizwa nge-Rainbow Effect.
I-Crystal Display Display (I-LCD)
Kungakhathaliseki ukuthi iphaneli flat noma ukubonakala kwangemuva, kukhona ton of zokukhetha emakethe for LCD noma Liquid Crystal Display TV. Izibonisi zamapaneli ezindiza zibhevishini ethandwayo kakhulu e- LCD ngenxa yokwakhiwa kwawo okuncane, okulula, okuyinto evumelana nabantu abafuna ukusebenzisa i-LCD yabo njenge-TV nokuqapha ikhompyutha . I-LCD ayitholakali ukushisa. Ama-LCD anezimpendulo ezisheshayo angabonisa umphumela wokuphefumula, kanti amanye ama-LCD angaba nomthelela womnyango wesikrini . Yingakho kubalulekile ukubona umcibisholo we-LCD ngaphambi kokuthenga ukubona ukuthi isikrini sihlangabezana nezidingo zakho.
Ama-Plasma Display Panels (PDP)
I-plasma yilona uhlobo lwethelevishini oluhlobene kakhulu ne-high-end home electronics. Lokhu kubangelwa ukuthi bathola ukumaketha okuningi okusitshela ukuthi i-plasma inemali engcono kakhulu engayithenga. Wonke amathelevishini e-plasma afika ezinhlobonhlobo zamaplanethi ahlukene. Iningi lilinganiselwe emkhakheni we-40-49. Amanani atholakala ngokuncintisana ngokumelene ne-LCD yedivishini yamaphaneli apane futhi afaka isithombe esinqabileyo esikubeka phakathi kwesenzo. I-Plasma isisindo esingaphezu kwe-LCD, kodwa ayikho into eyengeziwe yokwesekwa ayikwazanga ukusingatha. Bangakwazi ukushisa-kodwa kodwa naphezu kwamahemuhemu okuphambene nalokho, kuphelelwa amandla okwenza isithombe singakwazi ukugcwaliswa. Ngesikhathi besencane kakhulu ukulinganisa ngokunembile, amathelevishini e-plasma kufanele ahlale kuphi kusukela eminyakeni engu-10-20.
