Imawonetsa OLED, AMOLED, Super AMOLED, IPS – kuyerekezera, momwe mungasankhire

Imawonetsa OLED, AMOLED, Super AMOLED, IPS – kuyerekezera zomwe zili bwino kusankha muzochitika zamakono.

Momwe zowonera zimagwirira ntchito pamaukadaulo osiyanasiyana

Chophimba ndi chimodzi mwazinthu zofunika kwambiri pa foni yamakono, kompyuta kapena TV. Pakati pa mitundu yosiyanasiyana yoperekedwa kugulitsa, n’zovuta kumvetsa ubwino ndi kuipa kwa mayankho ena. Kuti mumvetse bwino mawonekedwe awo, muyenera kumvetsetsa kuti pali mitundu ina ya zowonetsera, malingana ndi matekinoloje omwe amagwiritsidwa ntchito pa ntchito.

Chiwonetsero cha LCD chokhala ndi kuwala kwa LED

Kuti musankhe zowonetsera zomwe zingakonde nthawi zina, munthu ayenera kuganizira mfundo za ntchito yawo ndi zomwe zikugwirizana nazo. Mitundu yodziwika bwino ya zowonetsera ndi izi (pogwiritsa ntchito zowonetsera pa smartphone monga chitsanzo):

1. Zowonetsa za LCD zimadziwika kuti zimagwiritsidwa ntchito mwachangu pazida zopangidwa ndi Apple. Chitsanzo ndi iPhone 11, iPhone XR, iPhone 8/8 Plus, ndi iPhone 7/7 Plus. Kuphatikiza pa iwo, zowonetsera zoterezi zimagwiritsidwa ntchito mu bajeti ndi ma foni apakati pa bajeti. Makamaka, zowonetsera zoterezi zitha kupezeka mu Honor 20/20 Pro, Xiaomi Redmi Note 7 ndi Huawei P30 Lite. IPS ndiye mtundu wodziwika bwino kwambiri wazithunzi za LCD.
2. Zowonetsera za OLED zimagwiritsidwa ntchito m’mafoni apamwamba komanso omwe ali pamitengo yapakati. Amagwiritsidwa ntchito mu mafoni a iPhone 11 Pro, 11 Pro Max, iPhone XS / XS Max ndi iPhone X. Huawei, Xiaomi ndi Sony flagships amakhalanso ndi zowonetsera zoterezi. Mitundu yaukadaulo woperekedwa ndi AMOLED, Super AMOLED.

Chipangizo chowonekera cha Super AMOLED[/ mawu] Zowonetsera za IPS zimagwiritsa ntchito makhiristo amadzimadzi kugwira ntchito. Pankhaniyi, mtundu wa pixel womwe mukufuna ukhoza kupezeka posintha mawonekedwe awo. Kuti mupeze chithunzi chapamwamba mu zitsanzo zoterezi, zimafunika kugwiritsa ntchito kuwala kwambuyo.
Zowonetsera za AMOLED zimagwiritsa ntchito ma LED ang’onoang’ono. Zikawonetsedwa, sizifunikira kuunikira kowonjezera. Kusiyana pakati pa mitundu iyi ya zowonetsera kuli mu luso la kujambula. Mu matrices a OLED, ma pixel amakhala ndi ma LED ofiira, a buluu ndi obiriwira, komanso capacitor ndi transistor. Kuphatikizika kwawo kumakupatsani mwayi wobala bwino mitundu yomwe mukufuna pazenera. Ma Microchips amagwiritsidwa ntchito kuwongolera ma pixel, omwe amakupatsani mwayi wopeza zithunzi za zovuta zilizonse potumiza ma siginecha pamzere womwe mukufuna ndi mzati popanga chithunzi pazenera.
Ntchito ya IPS imachokera pakugwiritsa ntchito makristasi amadzimadzi. Pixel iliyonse imakhala ndi tinthu tating’ono tamitundu yoyambirira: yofiira, yabuluu ndi yobiriwira. Iwo amatchedwa subpixels. Mwa kusintha kuwala kwawo, mutha kupeza mtundu uliwonse womwe mukufuna. Kuwala kwamphamvu kumagwiritsidwa ntchito kupanga chithunzi, kenako ma polarizer amazungulira madigiri 90 ogwirizana. Chimodzi mwa zigawo zomwe zimagwiritsidwa ntchito ndi makhiristo amadzimadzi, omwe amasintha katundu wawo pansi pa mphamvu yamagetsi. Kuwakopa, mutha kupeza mitundu yofunikira ya ma pixel azithunzi. Kuwala kumapezeka mwa kusintha kuwala kwa backlight. Makhiristo amadzimadzi samatulutsa kuwala paokha, amangokhudza njira yake.

Mawonekedwe amitundu yosiyanasiyana ya matrices – zabwino ndi zovuta

Kuti mumvetse kuti ndi njira iti yomwe ingakhale yabwino kwambiri pogula TV, muyenera kupanga malingaliro pamtundu uliwonse womwe watchulidwa wa matrices. Pomvetsa ubwino ndi kuipa kwawo, munthu akhoza kusankha chitsanzo chomwe chikugwirizana ndi zomwe wogwiritsa ntchito amafuna. Kuyerekeza kwa kubalana kwamitundu mukamayang’ana kuchokera pama foni am’manja omwe ali ndi IPS ndi AMOLED:

IPS matrices

Mukagwiritsidwa ntchito pa TV, mutha kupeza zotsatirazi:

1. Kupereka kwamtundu wamtundu wapamwamba kwambiri. Izi ndizoyenera osati kwa owonera okha, komanso kwa omwe amagwira ntchito mwaukadaulo ndi zithunzi ndi makanema, mwachitsanzo, ojambula.
2. Monga mukudziwira, nthawi zina zoyera zimatha kutenga mithunzi yosiyanasiyana, zomwe zimasokoneza malingaliro a wogwiritsa ntchito pazithunzi. Mtundu wa matrices omwe akuganiziridwa umapereka mtundu woyera woyera wopanda zowonjezera.
3. Imodzi mwa mavuto omwe ali ndi mitundu ina ya mawonetsedwe amakono ndi njira yochepa yomwe munthu angayang’ane. Ma matrices a IPS alibe malire otero. Apa mutha kuwona zomwe zikuwonetsedwa pazenera kuchokera pafupifupi mbali iliyonse. Panthawi imodzimodziyo, palibe zotsatira za kusokonezeka kwa mtundu kutengera mbali yowonera.
4. Ubwino wa chiwonetserocho sudzawonongeka pakapita nthawi, chifukwa palibe chowotcha pazenera.

Zotsatirazi zimawonedwa ngati zoyipa:

1. Ngakhale kuti chithunzicho chili chapamwamba kwambiri, mphamvu zambiri zimafunika kuti chinsalucho chiziyenda.
2. Pali nthawi yowonjezereka yoyankha.
3. Kusiyanitsa kochepa kumachepetsa ubwino wa chithunzi chotsatira.
4. Ngakhale mtundu woyera ukuwonetsedwa bwino, zomwezo sizinganenedwe zakuda, chifukwa sizidzakhala zoyera, koma mtundu wina wa mthunzi wofanana.

Posankha zida zokhala ndi chinsalu chotere, wogwiritsa ntchito sayenera kuganizira za mphamvu zokha, komanso kuganizira za kukhalapo kwa nthawi zovuta.

Kumbukirani kuti pali ma subtypes osiyanasiyana a IPS matrices. Makhalidwe apamwamba kwambiri ndi P-IPS ndi AH-IPS.

AMOLED matrix

Eni ake a zida zokhala ndi chophimba chotere azitha kupeza zabwino izi:

1. Yankho pa zipangizo zoterezi ndi mofulumira.
2. Kusiyanitsa kwabwino kwazithunzi.
3. Chophimbacho ndi chochepa.
4. Mitundu yowonetsedwa imakhutitsidwa.
5. Ndizotheka kupeza mtundu wapamwamba wakuda.
6. Chifukwa cha mawonekedwe aukadaulo omwe amagwiritsidwa ntchito, kugwiritsa ntchito mphamvu kuti mupeze chithunzi ndikocheperako poyerekeza ndi zowonetsera za IPS.
7. Pali mbali yayikulu yowonera.

Kuyerekeza kwa zida za LCD ndi OLED:
Kulimba kwa matrices otere kumakhudzana mwachindunji ndi kukhalapo kwa zovuta zotere:

1. Kuwala kwakukulu kwa mitundu yomwe imachokera nthawi zina kumapweteka maso.
2. Mkulu tilinazo mawotchi kuwonongeka. Ngakhale kuwonongeka pang’ono kungawononge chinsalu.
3. Panthawi yogwira ntchito, pakapita nthawi, mitunduyo idzazimiririka pang’onopang’ono.
4. Nthawi zambiri zimakhala zovuta kuwona chithunzi pazenera ndi kuwala kowala.
5. Chithunzi chamtundu woyera sichiri chapamwamba, chifukwa pangakhale mithunzi yowonjezera, yomwe nthawi zambiri imakhala ndi bluish kapena yellow tint.

Tekinoloje iyi ili ndi zabwino zake zofunika, zomwe kwa ogwiritsa ntchito ena zitha kukhala chifukwa chosankha chowonetsera. Matrix a LED:
Super AMOLED ndi chitukuko china cha AMOLED. Ndizochepa thupi ndipo zimakupatsani mwayi wopititsa patsogolo chithunzicho, ndikupangitsa kuti chikhale chosiyana komanso chowala. Tiyeneranso kukumbukira kuti kuwala kwa dzuwa kwatsika ndi 80%, zomwe zimakulolani kuti muwone bwino chithunzicho ngakhale pa tsiku lowala kwambiri. Kugwiritsa ntchito mphamvu kumachepetsedwa ndi 20%, zomwe zimapangitsa chipangizocho kukhala chokwera mtengo kwambiri. Ndikofunika kuzindikira kuti teknolojiyi ikupitirizabe kukula. Mwachitsanzo, zowonera za Super AMOLED Plus zidawonekera. Mitundu yatsopanoyi yapititsa patsogolo mawonekedwe azithunzi, zomwe zimachitika chifukwa chogwiritsa ntchito ukadaulo wa Real-Stripe. Chotsatiracho chasintha momwe zithunzi zimakokera.

Momwe mungadziwire chiwonetsero chomwe chili bwino muzochitika zina

Ogula amayang’ana ndondomeko ya chipangizochi posankha chipangizo choyenera, koma akhoza kuphonya luso logwiritsidwa ntchito. Komabe, mawonekedwe amtundu wosankhidwa wosankhidwa nthawi zina amatha kukhala otsimikiza. Chitsanzo cha izi ndikuwotcha pa skrini. Sizichitika pazowonetsera za IPS, zomwe zimapereka zifukwa zowerengera kugwiritsa ntchito kwanthawi yayitali kwaukadaulo wotere. Posankha AMOLED, chiwonetserocho chidzayaka pang’onopang’ono, chomwe chidzachepetsa kwambiri khalidwe lake. Chinthu china choyenera kusamala nacho ndicho kutopa kwa maso. Ndizotsika kwa ogula omwe amagwiritsa ntchito chophimba cha IPS, koma chokwera kwambiri kwa iwo omwe amakonda chiwonetsero cha AMOLED. Kumbali inayi, AMOLED imagwiritsa ntchito mphamvu zochepa ndipo ndiyoyenera kwambiri kwa iwo omwe amakonda zida zachuma. Ogwiritsanso angakonde kuyankha mwachangu komanso zakuda zabwino. Kusiyanitsa kopambana ndi mitundu yolemera ndi yoyenera kwa odziwa bwino chithunzithunzi. Matekinoloje onsewa ndi osiyana ndipo nthawi yomweyo amathandizirana. M’kupita kwa nthawi, matekinoloje opangira skrini amakula ndipo zofooka zawo zimathetsedwa kwathunthu kapena pang’ono. Komabe, posankha chipangizo, muyenera kudziwa ubwino ndi kuipa kwa mtundu uliwonse wawonetsero.
