QLED, OLED, IPS ndi NanoCell matrices mu TV – kuipa ndi ubwino

QLED, OLED, IPS ndi NanoCell TV – kusiyana kwa matrix, zabwino ndi zoyipa, ma Smart TV abwino kwambiri okhala ndi mtundu uliwonse wa matrix. Wopanga aliyense amayambitsa ukadaulo wake wopanga matrices okhala ndi mayina ake ogulitsa. Tsopano ndizovuta kumvetsetsa momwe chophimba chilichonse chimasiyanirana ndi mnzake, koma kwenikweni sizovuta kuchita. Nkhaniyi ifotokoza mitundu yonse ya matrices omwe amagwiritsidwa ntchito pa TV zamakono komanso kusiyana kwawo. Tiyeni tifanizire ma TV angapo ndikupereka malangizo pa kusankha masanjidwe abwino kwambiri.

Kodi matrix pa TV ndi chiyani ndipo amagwira ntchito bwanji

Matrix ndi skrini yomwe imayang’anira chakudya chazithunzi. Mothandizidwa ndi matrix, TV imawonetsa chithunzi chamtundu ndikusintha kuwala kwake. Matrix ali ndi ma LED ndi chosanjikiza chakumbuyo, chomwe chimapangitsa chithunzicho kuwoneka. Matrix aliwonse amagwira ntchito pa mfundo yomweyo, yomwe imagwiritsa ntchito ukadaulo wa RGB. Mukatanthauzira chidulecho, mumapeza Red, Green ndi Blue, ndiye kuti, wofiira, wobiriwira ndi wabuluu. Ndi chithandizo cha mitundu itatu iyi yomwe chithunzi chokwanira chimapangidwa. Ngati asakanizidwa mosiyanasiyana, ndiye kuti mutha kupeza mtundu uliwonse wamtundu womwe umapezeka m’maso mwa munthu.
Chiwonetserocho chili ndi ma pixel omwe amapanga chithunzicho. Pixel iliyonse imakhala ndi mababu amodzi kapena angapo amtundu uliwonse wa RGB. Posintha kuwala kwa diode, pixel yamtundu wina imapezeka. Pali ma pixel ambiri otere pa TV, ndi ochepa kwambiri moti akamagwira ntchito, timawona zithunzi zodziwika bwino. Ma matrices onse amasiyana momwe ma diode amayikidwira, njira yowunikira komanso zinthu zopangira. Kwenikweni, zowonetsera zonse za TV ndizofanana, zimasiyana ndi kuwala, kuchuluka kwa mitundu yophimbidwa ndi kuya kwakuda.

Kodi matrices ndi kusiyana kotani

Pali mitundu iwiri ikuluikulu ya matrices, LCD (liquid crystal display) ndi OLED (organic light emitting diode). Komanso, amagawidwa m’magulu ambiri, omwe samasiyana kwambiri, koma amapangidwa kuti azitha kutsatsa.

IPS

IPS ndi m’modzi mwa oyimira matrices a LCD. Ukadaulo uwu uli ndi kuphimba kwakukulu kwa mawonekedwe amtundu komanso mawonekedwe apamwamba mpaka madigiri a 178. Mu ma TV, gulu la LED limagwiritsidwa ntchito ngati chowunikira kumbuyo, chomwe chili pansi pa ma diode. Chifukwa cha izi, ma matrices a IPS alibe zakuda zakuda, popeza chiwonetsero chonsecho chimayatsidwa, mosasamala mtundu. Komanso, kuipa kwakukulu kumaphatikizapo nthawi yochepa yoyankha, koma izi sizofunikira kwa ma TV, ngakhale mutawasewera mu console. [id id mawu = “attach_9349” align = “aligncenter” wide = “499”]
Philips 75PUS8506 – Ukadaulo wa IPS [/ mawu] Ndiwolandila masamu amafilimu a TN +. Zowonetsera zakalezi zinali zocheperako, zokhala ndi ngodya zosawoneka bwino, koma nthawi zoyankhira kwambiri. Posankha TV, zofotokozera zingasonyeze teknoloji ya backlight ya LED, koma sizinena za IPS. Uwu ndi mtundu wa LCD backlight yomwe imagawa kuwala molingana pachithunzichi, osati m’mbali, monga momwe zinalili ndi zowonera zonse za LCD m’mbuyomu. Ngati muwona ma LED akulemba, ndiye kuti TV ili ndi gulu la LCD pogwiritsa ntchito ukadaulo wa IPS. [id id mawu = “attach_9980” align = “aligncenter” wide = “520”]

OLED

Matrices amenewa ndi okwera mtengo kwambiri ndipo amaikidwa mu ma TV amtengo wapatali okha. Chifukwa cha zomwe zimapangidwira, zimagwiritsidwa ntchito pama TV akuluakulu mainchesi 40 ndi kupitilira apo. Matrices a OLED amagwiritsa ntchito ma diode a organic emitting diode, iliyonse ili ndi kuwala kwake komweko, komwe kuya kwakuda kumakhala kopanda malire. Pamene dera lakuda likuwonekera pazenera, ma pixel omwe ali pamalo ano amazimitsidwa, pomwe chithunzicho chimakhala chosiyana kwambiri. Pachithunzi chomwe chili pansipa, matrix a OLED ali kumanzere, IPS ili kumanja. Kusiyana pamtundu wakuda kumawonekera nthawi yomweyo.

Komanso, matrices a OLED amasiyanitsidwa ndi kuwala kwakukulu mpaka 4000 nits ndi kusiyana kwakukulu.

Zoyipa zake ndi monga momwe kuwala kumasinthira. Ma pixel sangasinthe kuwala, kotero ukadaulo wa PWM umagwiritsidwa ntchito kutsitsa. Ndi iyo, kuwala kwambuyo kumayamba kunyezimira mwachangu kwambiri, koma diso lamunthu silingathe kuwona kufinya mwachangu koteroko, kotero zikuwoneka kwa ife kuti kuwala kwayamba kuchepa. Komabe, m’malo mwake, nyali yakumbuyo imakhala yoyaka nthawi zonse, imangowala pang’ono. Chifukwa cha zimenezi, anthu ena amamva kupweteka mutu akamaonera kwa nthawi yaitali. Komanso, ma matrices a OLED amakonda kutenthedwa ndi pixel kuposa masiku onse. Ngati chithunzi chomwechi chikuwonetsedwa pazenera kwa nthawi yayitali, ndiye kuti “chimaundana”. Izi zimachitika patatha zaka zingapo zogwiritsa ntchito kwambiri ma TV a OLED, kotero sakhala olimba ngati omwe akupikisana nawo a LCD. M’ma TV amakono, opanga amakonza cholakwikacho m’njira zosiyanasiyana, chifukwa matrix a OLED amatha kugwira ntchito mokhazikika mpaka zaka 5. Koma posakhalitsa zidzapsa. Izi sizingakhudze ntchito ya chinsalu mwanjira iliyonse, mitundu yokhayo idzasokonezedwa pang’ono, chifukwa ma pixel ena adzawala mosiyana pang’ono. Mutha kuwona kusiyana pachithunzi pansipa.

Mtengo wa QLED

Ngakhale ndi dzina lofananalo, QLED sichigwirizana ndi OLED mwanjira iliyonse. Awa ndi matrices a LCD okhala ndi ukadaulo wowunikira kumbuyo womwe umagwiritsa ntchito madontho a quantum. Ali pafupi ndi OLED mumtundu wazithunzi, koma samawononga ndalama zambiri. QLED ndi yofanana kwambiri ndi IPS koma ili ndi kusiyana kwabwinoko komanso zakuda zakuda (pafupifupi 100%).
QLED ndi dzina lotsatsa la mapanelo a LCD omwe makampani ena monga Samsung ndi TCL amagwiritsa ntchito pazida zawo. Opanga ena monga Vizio ndi Hisense amagwiritsa ntchito ukadaulo wa quantum dot koma sagwiritsa ntchito QLED pakutsatsa kwawo. Kuti zinthu zikhale zosokoneza kwambiri, LG ikutulutsa ma TV amtundu wa quantum omwe amagulitsidwa pansi pa mtundu wa QNED. M’malo mwake, awa onse ndi mapanelo a LCD, omwe ali ofanana kwambiri ndi IPS.

Neo QLED

Postscript Neo ndi m’badwo watsopano wa matrices a LCD okhala ndi madontho ochulukirapo pakuwunikiranso. Mtunduwu umasiyana ndi wanthawi zonse wa QLED pamadontho ochepetsedwa komanso ambiri pa TV imodzi. Chifukwa cha izi, zimasintha kusintha kwa backlight, kusiyana ndi kuwala. Palibe kusiyana kwakukulu kuchokera ku QLED. Ma TV a OLED vs. Nanocell: LG OLED48CX6LA ndi LG 65NANO866NA ndemanga – https://youtu.be/1CLDSoRcb9A

NanoCell

Nano Cell ndi dzina lamalonda la zowonetsera kuchokera ku LG, yomwe imagwiritsa ntchito ukadaulo wa IPS pachimake. Ndiye kuti, awa ndi mapanelo odziwika bwino a LCD. Wopanga amatenga ma IPS-matrices wamba, omwe amagwiritsidwa ntchito paliponse, ndikuwonjezeranso gawo lina la choyezera kuwala. Izi zimabweretsa kutulutsa bwino kwa mitundu, kusiyanasiyana kosiyanasiyana komanso kuchuluka kwamphamvu. Zowona, palibe kusiyana kwakukulu ndi mapanelo ena a LCD.

Kodi ukadaulo wopanga matrix ndi mtsogolo

Pakatikati pawo, ma TV ambiri amagwiritsa ntchito mapanelo a LCD pazowonetsera zawo. Iwo ndi otsika mtengo, apamwamba komanso owala. Koma pali kale teknoloji yatsopano yopangira zowonetsera, yomwe ndi OLED. Matrices awa safuna kuwala kosiyana, komwe kumawapatsa kusiyana kwakukulu, zakuda zakuya kwambiri komanso kuwala kopambana kwambiri. Ndi lusoli kuti ma TV onse adzapangidwa m’tsogolomu, makamaka pamene zidzatheka kupanga kupanga kwawo kukhala kopanda mtengo kwambiri ndikuchotsa zofooka za PWM. Kale, pogwiritsa ntchito chitsanzo cha mafoni a m’manja, momwe OLED ikuchulukirachulukira ngakhale m’mitundu yotsika mtengo, opanga akuchotsa kuipa kwakukulu kwa ma LED a organic.
