Yiziphi izinhlobo ezahlukene ngabaqaphi?

Gada - isakhi esibalulekile yiluphi uhlelo kukhompyutha. Kuyinto idivayisi lapho ikhompyutha utshela umuntu umphumela umsebenzi wakhe. Uma usebenzisa i-mouse nekhibhodi, umsebenzisi iletha idatha yoqobo, ngokusebenzisa isithombe qapha screen ikhompyutha yazisa umphumela ukubalisisa kwabo.
Njalo is uhlobo inkhulumomphendvulwano. Ngokungafani encane izingxenye zangaphakathi, kule divayisi akunakwenzeka ukuba uphawule, ngakho umbono jikelele kuba bonke. Nge lesi sihloko thina ukwelekelela isizinda solwazi, sihlolisise izinhlobo nabaqaphi.

Kuye zinhlobo esetshenziswa isikrini wonke amadivayisi enjalo isibonisi zingahlukaniswa ngamaqembu amabili amakhulu - lwanamuhla ketshezi-crystal (LCD, TFT, LCD), futhi cishe ikhishiwe ukusuka nokukhiqizwa kwezinto ngobuningi, cathode-ray (CRT, CRT). Ngezinye izikhathi uhlu uhlobo ayahambelana yesithathu - LCDs, kodwa kungcono pretty izixazululo eziqondile kahle hle okwandile. Ngakho, ukutadisha izinhlobo ngabaqaphi anqunyelwe LCD futhi CRT.

Ngokuqinisekile, abaningi basayikhumbula namanje indlela namathelevishini sibheke ekuqaleni "Inkathi crystal liquid." Kwakumelwe kudivayisi ngempela okukhulu, isikrini ukuthi wayengeyona bushelelezi ephelele. Nakuba eminyakeni yamuva isimo kulesi sici kuye sashintsha ngokuphawulekayo. Ubani oye waba nalo yini ithuba ukubona ngaphakathi emzimbeni womuntu CRT TV, ukwazi ukuthi cishe yonke ivolumu elalihlala a cathode ray tube, futhi ubukhulu ibhodi ukulawula akuvamile kudlulwe landscape endaweni ephepheni. Ukuhlobana phakathi qapha kanye TV ngokwayo: basebenzisa okufanayo yokusebenza isimiso. Yiqiniso, ngaphakathi ukukhiqizwa ubuchwepheshe obufanayo.

Uma ucabangela izinhlobo ngabaqaphi ukuthi asikwazi izici lokhu noma lokhuya isinqumo indiva. Ngakho, senza uhlu izinzuzo CRT Abaqaphi :

- ukudluliswa cishe ekahle zonke imibala, ngisho entry level imodeli kulesi sici ikude ngaphambi ezibizayo LCD qapha;

- ukuntuleka engeli wokubuka - isithombe esikrinini uhlale ebonakalayo, kungakhathaliseki uwe kanjani ku ulayini emehlweni;

- Amaphikseli efile, isiswebhu yonkana okucaciswe luketshezi ubuchwepheshe, a CRT akukwazi onobuhle;

- azikho izinkinga nge Lubrication isithombe ngesikhathi kukhonjiswa isinyathelo ngokushesha.

Kodwa-LCD Abaqaphi ngiziqhayise ukubukwa ngezici ezihlukahlukene kakhulu:

- Izinga eliphansi amandla amapayipi, ukubaluleka kusiqinisa 40 W (qhathanisa 80 kanye CRT);

- Ubukhulu compact nesisindo ongaphakeme, ngakho ukubeka leli thuluzi odongeni, asikho isidingo ukufaka besiyoba sikhulu isakhiwo ukumiswa;

- umthwalo kakhulu encane emehlweni: esiphansi uhlelo ukukhanya kulokolokoza imvamisa kuba emakhulwini megahertz (ngemibono ephambene kwakhiwa, ngenxa khona PWM imigomo, ke isatholakala);

- ekahle isithombe esengqondweni iyacaca futhi ukungabi khona izinkinga ngaphakathi ngemishayo ukuxuba ngesinye isikhathi, kanye geometry ukungakwazi ukuhlanekezela.

Ngabaqaphi LCD benezingane eziningi izici bengekho kule CRT. Lokhu kungenxa igebe ebanzi kakhulu kwezobuchwepheshe. Ngokwesibonelo, lezi zinhlobo ezilandelayo matrices Abaqaphi: I TN ezivamile, IPS eziphambili, ukuhlela kabusha ezihlukahlukene VA. Ngamunye wabo kuphela izici wakhe esingokwemvelo ukuthi kukhona esibalulekile okufanele sicatshangelwe lapho ukuthenga qapha LCD.
