Ibonisa i-OLED, i-AMOLED, i-Super AMOLED, i-IPS – ukuqhathanisa, indlela yokukhetha

Ibonisa i-OLED, i-AMOLED, i-Super AMOLED, i-IPS – ukuqhathanisa okungcono ukukhetha ezintweni ezingokoqobo zesimanje.

Indlela izikrini ezisebenza ngayo kubuchwepheshe obuhlukahlukene

Isikrini singenye yezinto ezibaluleke kakhulu ze-smartphone, ikhompuyutha noma i-TV. Phakathi kwezinhlobonhlobo zamamodeli ahlinzekwa ukudayiswa, kunzima ukuqonda izinzuzo nezinkinga zezixazululo ezithile. Ukuze uqonde kangcono izici zabo, udinga ukuqonda ukuthi kunezinhlobo ezithile zezikrini, kuye ngobuchwepheshe obusetshenziselwa umsebenzi.

Isibonisi se-LCD esinokukhanya kwangemuva kwe-LED

Ukunquma ukuthi yiziphi iziboniso ongakhetha kuzo ezimweni ezithile, umuntu kufanele acabangele izimiso zokusebenza kwazo kanye nezici ezihambisana nazo. Izinhlobo zezikrini ezaziwa kakhulu yilezi ezilandelayo (usebenzisa izibonisi ze-smartphone njengesibonelo):

1. Izibonisi ze- LCD zaziwa ngokusetshenziswa ngenkuthalo kumadivayisi akhiqizwa i-Apple. Isibonelo i-iPhone 11, i-iPhone XR, i-iPhone 8/8 Plus, ne-iPhone 7/7 Plus. Ngaphezu kwabo, izikrini ezinjalo zisetshenziswa kubhajethi kanye nama-smartphones aphakathi kwesabelomali. Ikakhulukazi, izikrini ezinjalo zingatholakala kumamodeli we-Honor 20/20 Pro, Xiaomi Redmi Note 7 kanye neHuawei P30 Lite. I-IPS iyinhlobonhlobo eyaziwa kakhulu yezikrini ze-LCD.
2. Izibonisi ze- OLED zisetshenziswa kuma-smartphones aphambili kanye nakulawo aphakathi kwebanga lentengo. Asetshenziswa kuma-smartphones e-iPhone 11 Pro, 11 Pro Max, iPhone XS / XS Max kanye ne-iPhone X. I-Huawei, i-Xiaomi ne-flagship yakwa-Sony nazo zinezikrini ezinjalo. Izinhlobonhlobo zobuchwepheshe obethulwa yi-AMOLED, i-Super AMOLED.

Idivayisi yesikrini ye-Super AMOLED[/caption] Izibonisi ze-IPS zisebenzisa amakristalu awuketshezi ukuze zisebenze. Kulokhu, umbala wephikseli oyifunayo ungatholwa ngokushintsha umumo wawo. Ukuze uthole isithombe sekhwalithi ephezulu kumamodeli anjalo, kuyadingeka ukusebenzisa i-backlight.
Izibonisi ze-AMOLED zisebenzisa ama-LED amancane. Uma eboniswa, awadingi ukukhanya okwengeziwe. Umehluko phakathi kwalezi zinhlobo zokuboniswa usebuchwephesheni bezithombe. Kumatikuletsheni we-OLED, amaphikseli aqukethe ama-LED amancane abomvu, aluhlaza okwesibhakabhaka naluhlaza, kanye ne-capacitor ne-transistor. Inhlanganisela yabo ikuvumela ukuthi ukhiqize ngokunembile imibala oyifunayo esikrinini. Ama-microchips asetshenziselwa ukulawula amaphikseli, akuvumela ukuthi uthole izithombe cishe zanoma yiliphi izinga lobunzima ngokuthumela amasiginali kumugqa kanye nekholomu oyifunayo lapho wenza isithombe esikrinini.
Umsebenzi we-IPS usekelwe ekusetshenzisweni kwamakristalu awuketshezi. Iphikseli ngalinye liqukethe amakristalu amancane emibala eyinhloko: obomvu, oluhlaza okwesibhakabhaka nokuluhlaza. Abizwa ngokuthi ama-subpixels. Ngokulungisa ukukhanya kwabo, ungathola noma yimuphi umbala oyifunayo. Ukukhanyisa okunamandla kusetshenziswa ukwenza isithombe, bese ama-polarizer azungezisa ama-degree angama-90 ngokuhlobene. Esinye sezingqimba ezisetshenziswayo amakristalu e-liquid, ashintsha izakhiwo zawo ngaphansi kwesenzo se-voltage yokulawula. Ukuwathonya, ungathola imibala edingekayo yamaphikseli wesithombe. Ukukhanya kutholakala ngokulungisa i-backlight. Amakristalu awuketshezi awakhiphi ukukhanya ngokwawo, athonya indlela yawo kuphela.

Izici zezinhlobo ezahlukene zamatrices – izinzuzo kanye nokubi

Ukuze uqonde ukuthi iyiphi inketho engakhethwa kakhulu uma uthenga i-TV, udinga ukwenza umbono mayelana nohlobo ngalunye olushiwo lukamatikuletsheni. Ukuqonda izinzuzo nezinkinga zabo, umuntu angakhetha imodeli evumelana kangcono nezidingo zomsebenzisi. Ukuqhathaniswa kokukhiqizwa kombala uma kubhekwa ku-engeli yama-smartphones ane-IPS ne-AMOLED:

IPS matrices

Uma usetshenziswa kuma-TV, ungathola izinzuzo ezilandelayo:

1. Ukunikezwa kombala wesithombe sekhwalithi ephezulu. Lokhu akulungile kubabukeli kuphela, kodwa nalabo abasebenza kahle ngezithombe namavidiyo, isibonelo, abathwebuli bezithombe.
2. Njengoba wazi, ngezinye izikhathi umbala omhlophe ungathatha ama-shades ahlukene, okuphazamisa umbono womsebenzisi wezithombe. Uhlobo lukamatikuletsheni olucatshangelwayo lunikeza umbala omhlophe omsulwa ngaphandle kwanoma yiziphi izithasiselo.
3. Enye yezinkinga ngezinhlobo ezithile zezibonisi zesimanje i-engeli elinganiselwe umuntu angabheka kuyo. Omatikuletsheni be-IPS abanawo umkhawulo onjalo. Lapha ungabona okuboniswa esikrinini cishe kunoma iyiphi i-engeli. Ngesikhathi esifanayo, awukho umphumela wokuhlanekezela kombala kuye ngokuthi i-angle yokubuka.
4. Izinga lesibonisi ngeke lehle ngokuhamba kwesikhathi, njengoba ungekho umphumela wokushiswa kwesikrini.

Okulandelayo kuphawulwa njengemibi:

1. Ngaphandle kwekhwalithi yesithombe ephezulu, inani elikhulu lamandla liyadingeka ukugcina isikrini sisebenza.
2. Kukhona isikhathi sokuphendula esikhulisiwe.
3. Ukugqama okuphansi kunciphisa ikhwalithi yesithombe esiwumphumela.
4. Nakuba umbala omhlophe uboniswa ngokuphelele, okufanayo akunakushiwo mayelana nomnyama, ngoba ngeke kube okuhlanzekile, kodwa uhlobo oluthile lomthunzi ofanayo.

Lapho ukhetha amadivayisi anesikrini esinjalo, umsebenzisi akumele acabangele amandla kuphela, kodwa futhi acabangele ukuba khona kwezikhathi eziyinkinga.

Khumbula ukuthi kunezinhlobo ezincane ezihlukene zamatrices e-IPS. Izinga eliphezulu kakhulu i-P-IPS ne-AH-IPS.

I-matrix ye-AMOLED

Abanikazi bamadivayisi anesikrini esinjalo bazokwazi ukuthola izinzuzo ezilandelayo:

1. Ukusabela kumadivayisi anjalo kuyashesha.
2. Ukugqama okuhle kwesithombe.
3. Isikrini sincane.
4. Imibala ebonisiwe igcwele.
5. Kungenzeka ukuthola umbala omnyama wekhwalithi ephezulu.
6. Ngenxa yezici zobuchwepheshe obusetshenzisiwe, ukusetshenziswa kwamandla okuthola isithombe kuncane kakhulu uma kuqhathaniswa nezibonisi ze-IPS.
7. Kukhona i-engeli enkulu yokubuka.

Ukuqhathaniswa kwemishini ye-LCD ne-OLED:
Amandla alawo matrices ahlobene ngokuqondile nokuba khona kobubi obunjalo:

1. Ukukhanya okuphezulu kwemibala ephumela ngezinye izikhathi kungalimaza amehlo.
2. Ukuzwela okuphezulu ekulimaleni komshini. Ngisho nomonakalo omncane ungalimaza isikrini.
3. Ngesikhathi sokusebenza, ngokuhamba kwesikhathi, imibala izophela kancane kancane.
4. Kuvamise ukuba nzima ukubona isithombe esikrinini sinokukhanya okukhanyayo.
5. Isithombe sombala omhlophe akusona sekhwalithi ephezulu, njengoba kungase kube nama-shades engeziwe, ngokuvamile ane-tint eluhlaza okwesibhakabhaka noma ephuzi.

Lobu buchwepheshe bunezinzuzo zabo ezibalulekile, okungenzeka kwabanye abasebenzisi kube isizathu esinqumayo sokukhetha isibonisi esinjalo. I-Matrix ye-LED:
I-Super AMOLED iyintuthuko eyengeziwe ye-AMOLED. Izacile futhi ikuvumela ukuthi uthuthukise ikhwalithi yesithombe, usenze sihluke kakhulu futhi sikhanye. Kumele futhi kuqashelwe ukuthi ukukhanya kwelanga kwehle ngo-80%, okukuvumela ukuba ubone isithombe ngokucacile ngisho nangosuku olukhanyayo libalele. Ukusetshenziswa kwamandla kwehliswe ngo-20%, okwenza idivayisi yonge nakakhulu. Kubalulekile ukuqaphela ukuthi lobu buchwepheshe buyaqhubeka nokuthuthuka. Isibonelo, izikrini ze-Super AMOLED Plus zivele. Amamodeli amasha athuthuke nakakhulu ikhwalithi yesithombe, okubangelwa ukusetshenziswa kobuchwepheshe be-Real-Stripe. Lesi sakamuva sishintshe indlela izithombe ezidwetshwa ngayo.

Unganquma kanjani ukuthi yisiphi isibonisi esingcono ezimeni ezithile

Abasebenzisi babheka ukucaciswa kwedivayisi lapho bekhetha idivayisi efanele, kodwa bangase baphuthelwe ubuchwepheshe obusetshenzisiwe. Nokho, izici zohlobo olukhethiwe lokubonisa kwezinye izimo zinganquma. Isibonelo salokhu ukushiswa kwesikrini. Akwenzeki kuzibonisi ze-IPS, okunikeza izizathu zokubala ekusetshenzisweni kwesikhathi eside kobuchwepheshe obunjalo. Lapho ukhetha i-AMOLED, isibonisi sizosha kancane kancane, okuzonciphisa ngokuphawulekayo ikhwalithi yaso. Esinye isici okufanele sinake ukukhathala okubukwayo. Iphansi kubathengi abasebenzisa isikrini se-IPS, kodwa iphakeme kakhulu kulabo abakhetha isibonisi se-AMOLED. Ngakolunye uhlangothi, i-AMOLED idla amandla amancane futhi ifaneleka kakhulu kulabo abakhetha amadivaysi ayongayo. Abasebenzisi bangase futhi bathande impendulo esheshayo nekhwalithi emnyama. Ukungafani okuhle kakhulu nemibala ecebile ifaneleka ochwepheshe bekhwalithi yesithombe esihle. Bobabili ubuchwepheshe buhlukile futhi ngesikhathi esifanayo kuyaphelelisana. Ngokuhamba kwesikhathi, ubuchwepheshe bokukhiqiza isikrini buthuthuka futhi ukushiyeka kwabo kuqedwa ngokuphelele noma kancane. Nokho, lapho ukhetha idivayisi, udinga ukwazi okuhle nokubi kohlobo ngalunye lwesibonisi.
