Ukuchaza umehluko Phakathi kuka-6, 8 no-10-bit Ukubonisa
Ububanzi bombala wekhompiyutha buchazwa ngokujula kombala wesikhathi. Lokhu kusho inani lemibala ikhompyutha engayibonisa kumsebenzisi. Ubuningi bombala obonakala kakhulu abasebenzisi abazobona uma besebenzisana nama- PC bayizi- 8-bit (imibala engu-256), 16-bit (imibala engu-65,536) no-24-bit (imibala eyizigidi ezingu-16.7). Umbala weqiniso (noma umbala we-24-bit) yimodi evame ukusetshenziswa kakhulu manje njengoba amakhompyutha athole amazinga okwanele ukuze asebenze kalula kulokhu ukujula kombala. Abanye basebenzise ubuchwepheshe bokujula kombala we-32-bit, kodwa lokhu kusetshenziselwa njengendlela yokwenza umbala ukuze uthole amathoni amaningi achaziwe uma kunikezwe phansi ezingeni le-24-bit.
Isivinini Sokusheshisa
Abaqaphi be-LCD bahlangabezane nenkinga encane uma kuziwa ekubhekaneni nombala nesivinini. Umbala kwi-LCD iqukethe izingqimba ezintathu zamachashazi anemibala akha i-pixel yokugcina. Ukuze ubonise umbala onikeziwe, okwamanje kufanele kusetshenziswe kwendlalelo ngayinye yombala ukuze unike amandla okufunayo okwenza umbala wokugcina. Inkinga ukuthi ukuthola imibala, okwamanje kufanele ihambise ama-crystals futhi avule kumazinga afisa kakhulu. Lokhu kuguqulwa kusukela ekuhambeni kokuya kwesimo sekubizwa ngokuthi isikhathi sokuphendula. Ezikhathini eziningi izikrini, lokhu kulinganiswa cishe 8 kuya ku-12m.
Inkinga yukuthi abaningi abahloli be- LCD basetshenziselwa ukubuka ividiyo noma ukunyuka esikrinini. Ngesikhathi esiphezulu sempendulo sokushintshwa ukusuka ku-on states, ama-pixels okufanele aguquke emazingeni ombala omusha ahambe isignali futhi abange nomphumela owaziwa ngokuthi ukufiphaza kwe-motion. Lokhu akuyona inkinga uma isilondolozi sisetshenziselwa izinhlelo zokusebenza ezifana nesofthiwe yokukhiqiza , kodwa ngevidiyo nokunyakaza, kungaba yizindaba.
Njengoba abathengi befuna izikrini ezisheshayo, kukhona okudingeka kwenziwe ukuze kuthuthukiswe izikhathi zokuphendula. Ukwenza lokhu kube lula, abakhiqizi abaningi baphendukela ekunciphiseni inani lamazinga ahlinzeka ngamaphikseli ombala ngamunye. Lokhu ukunciphisa inani lamazinga okuqina kuvumela ukuthi izikhathi zokuphendula zishiye kodwa kunomphumela wokunciphisa inani eliphelele lemilayezo engenziwa.
6-Bit, 8-Bit noma 10-Bit Umbala
Ukujula kombala bekukhulunywe ngaphambili ngenani lemibala ukuthi isikrini singanikeza, kodwa uma ubhekisela kuma-panel LCD inani lamanothi umbala ngamunye ongayinikeza wona usetshenziswa. Lokhu kungenza kube nzima ukuqonda izinto, kodwa ukubonisa, sizobheka izibalo zalo. Isibonelo, umbala we-24-bit noma weqiniso unemibala emithathu ngayinye enezinhlamvu ezingu-8 zombala. Isibalo, lokhu kuboniswa ngokuthi:
- 2 ^ 8 x 2 ^ 8 x 2 ^ 8 = 256 x 256 x 256 = 16,777.216
Izibheki ze-LCD ezisheshayo ngokuvamile zinciphisa inani lezinkinobho ngombala ngamunye kuya ku-6 esikhundleni sezinga elijwayelekile 8. Lo mbala ongu-6-bit uzokhipha imibala embalwa kakhulu kune-8-bit njengoba sibona uma senza izibalo:
- 2 ^ 6 x 2 ^ 6 x 2 ^ 6 = 64 x 64 x 64 = 262,144
Lokhu kuncane kakhulu kunokubonisa umbala weqiniso okwakungabonakala emehlweni esintu. Ukuze uzungeze le nkinga, abakhiqizi basebenzisa inqubo ebizwa ngokuthi i-dithering. Lokhu kuyimiphumela lapho amaphikseli aseduzane asebenzisa khona ama-shades noma umbala ohlukile okhohlisayo iso lomuntu ekubona umbala oyifunayo nakuba kungenjalo ngempela umbala. Isithombe sephephandaba lombala kuyindlela enhle yokubona lo mphumela ekusebenzeni. Ukuphrinta umphumela kuthiwa yi-halftones. Ngokusebenzisa le nqubo, abakhiqizi bathi bafinyelele ukujula kombala eduze kwalezo zemibala yangempela yombala.
Kukhona elinye izinga lokubonisa elisetshenziswe ochwepheshe ababizwa ngokuthi ukubonisa okungu-10-bit. Ngokombono, lokhu kungabonisa imibala engaphezu kwezigidi eziyizinkulungwane, ngaphezu kwanokuba iso lomuntu lingabonisa. Kunezinamba eziningi zokungabikho kulezi zinhlobo zokuboniswa nokuthi kungani zisetshenziswa kuphela ngabachwepheshe. Okokuqala, inani lemininingwane edingekayo kumbala ophezulu kangaka kudinga uxhumano lwe-bandwidth eliphezulu kakhulu. Ngokuvamile, laba abaqaphi namakhadi wevidiyo bazosebenzisa isixhumi se- DisplayPort . Okwesibili, yize ikhadi legrafu lizokhipha imibala engaphezu kwezigidigidi, imibala yembala yebala noma ububanzi bemibala engaboniswa ngempela iyoba ngaphansi kwalokhu. Ngisho nemikhiqizo ye-ultra-wide color gamut esekela umbala we-10-bit ayikwazi ngempela ukunikeza yonke imibala. Konke lokhu kubhekisela ekuboniseni okuvame ukuhamba kancane futhi okubiza kakhulu ukuthi kungani kungavamile kubathengi.
Indlela Yokutshela Ukuthi Kuningi Kangakanani Ukusebenzisa Okusetshenziswayo
Le yinkinga enkulu kunazo zonke kubantu ababuka ukuthenga i-LCD monitor. Ukuboniswa kobuchwepheshe kuzovame ukusheshisa ukukhuluma ngokusekelwa kombala we-10-bit. Futhi, kufanele ubheke umbala wangempela wombala walezi ziboniso noma kunjalo. Abathengi abaningi abasebenzisi ngeke bathi bangaki abasebenzisa ngempela. Esikhundleni salokho, bavame ukuhlunga inani lemibala abayisekelayo. Uma umkhiqizi ebala umbala njengemibala eyizigidi ezingu-16.7, kufanele kucatshangelwe ukuthi ukubonisa kungu-8-bit ngombala ngamunye. Uma imibala ibalwa njengezigidi ezingu-16.2 noma izigidi ezingu-16, abathengi kufanele bacabange ukuthi isebenzisa ukujula kombala ngamunye ka-6-bit. Uma kungekho ubuningi bombala obudweliswe, kufanele kucatshangwe ukuthi abahloli bama-2 ms noma okusheshayo bayoba yi-6-bit futhi iningi elingu-8 ms futhi amaphaneli aphansi angama-8-bit.
Ingabe Kuyadingeka Ngempela?
Lokhu kubaluleke kakhulu kumsebenzisi wangempela nokuthi ikhompyutha isetshenziselwa. Inani lombala liyabaluleke kakhulu kulabo abenza umsebenzi ochwepheshe kwihluzo. Kulaba bantu, inani lombala eliboniswa esikrinini kubaluleke kakhulu. Umthengi ojwayelekile ngeke adinge ngempela leveli yokumelela umbala ngokuqapha kwawo. Ngenxa yalokho, cishe akunandaba. Abantu abasebenzisa ukubonisa kwabo imidlalo yevidiyo noma ukubukela amavidiyo ngeke banakekele ngenani lemibala eyenziwe yi-LCD kodwa ngejubane lapho lingaboniswa khona. Ngenxa yalokho, kungcono ukunquma izidingo zakho bese usetha ukuthenga kwakho kulezo zindlela.
