Smart TV

Kupokana pamusoro pezvinoreva mavara ose aya ndekwomuzvarirwo kana uchitenga terevhizheni itsva. Smart TV modhi dzine masisitimu akasiyana, ane LED, LCD, OLED, QLED uye MicroLED skrini uye uchafanirwa kusarudza kuti ndeipi sarudzo yakanakisa.

Pamusoro pemutengo, zvakakosha kunzwisisa kuti tekinoroji yega yega yekuratidzira inoshanda sei paTV yako.

Muchidimbu, nzwisisa mutsauko pakati pemasikirini modhi, zvakanakira uye ndeapi matambudziko makuru aungasangana nawo kana ukafunga kutenga imwe yacho.

Misiyano pakati pekuratidzira tekinoroji

Parizvino kune akawanda mapaneru eSmart TVs, imwe neimwe iine maficha ayo uye tekinoroji. Pano tinokuratidza imwe neimwe kuitira kuti uzive kuti ndeipi yakakunakira.

LCD

LCD (Liquid Crystal Display) tekinoroji inopa hupenyu kune inonzi mvura yekristaro inoratidzira. Vane girazi rakatetepa regirazi rine makristasi anodzorwa nemagetsi mukati, pakati pemapepa maviri akajeka (anova mafirita epolarizing).

Iyi liquid crystal panel inovhenekerwa nemwenje weCCFL (fluorescent). Iyo chena backlight inovhenekera maseru ekutanga mavara (girinhi, tsvuku uye bhuruu, iyo yakakurumbira RGB) uye izvi ndizvo zvinoumba mifananidzo yemavara yaunoona.

Kusimba kwemagetsi emagetsi anogashirwa nekriststal inotsanangura mafambiro ayo, ayo anobvumira kuti chiedza chakawanda kana chishoma kudarika nepasefa inoumbwa neatatu mapixels.

Mukuita uku, ma transistors anouya mukutamba pamhando yefirimu, ine zita rinonzi Thin Film Transistor (TFT). Ndosaka zvakajairika kuona maLCD/TFT modhi. Nekudaro, iyo acronym haireve kune imwe mhando yeLCD skrini, asi kune yakajairika chikamu cheLCD skrini.

Iyo LCD skrini inotambura nematambudziko maviri: 1) kune mamirioni emusanganiswa wemavara uye LCD skrini dzimwe nguva haisi iyo yakatendeka; 2) dema harina kumbobvira ranyanya chokwadi, nekuti girazi rinofanirwa kuvharira mwenje wese kuumba 100% yakasviba nzvimbo, chete tekinoroji haigone kuzviita nemazvo, zvichikonzera "grey vatema" kana vatema vakareruka.

PaTFT LCD skrini zvinogoneka zvakare kuve nematambudziko nekona yekutarisa kana usiri 100% yakatarisana nechidzitiro. Iri harisi dambudziko riripo kuLCD, asi kuTFT uye muLCD TVs ine IPS, senge LG's, tine makona ekuona akafara.

akatungamirira

Iyo LED (Chiedza Emitting Diode) iine chiedza-emitting diode. Mune mamwe mazwi, terevhizheni ine LED skrini haisi chimwe chinhu kunze kwematerevhizheni ane LCD skrini (iyo inogona kana kusave IPS) ine backlight inoshandisa malight-emitting diode.

Kubatsira kwayo kukuru ndeyekuti inoshandisa simba shoma pane yechinyakare LCD panel. Nokudaro, iyo LED inoshanda nenzira yakafanana neLCD, asi chiedza chinoshandiswa chakasiyana, chine chiedza chinobudisa diodes chemvura crystal display. Panzvimbo pechidzitiro chese chinogamuchira chiedza, madotsi anovhenekerwa zvakasiyana, izvo zvinovandudza tsananguro, mavara uye musiyano.

Ndapota cherechedzai: 1) LCD TV inoshandisa Cold Cathode Fluorescent Lamps (CCFL) kujekesa pasi rose repaneti; 2) nepo LED (rudzi rweLCD) inoshandisa nhevedzano yediki, inoshanda zvakanyanya chiedza-emitting diodes (LEDs) kuvhenekera iyi pani.

OLED

Zvakajairika kunzwa kuti OLED (Organic Chiedza-Emitting Diode) ishanduko ye LED (Chiedza Emitting Diode), nekuti iyo organic diode, zvinhu zvinoshanduka.

MaOLED, nekuda kweiyi tekinoroji, haashandise general backlight kune ese mapixels avo, ayo anovhenekera ega kana magetsi achipfuura neimwe yadzo. Ndokureva kuti, OLED mapaneru ane yavo yemwenje kubuda, isina backlight.

Izvo zvinobatsira zvakanyanya kujeka mavara, kupenya uye kusiyanisa. Sezvo pixel yega yega iine kuzvimiririra mukuburitswa kwechiedza, kana nguva yasvika yekuburitsa ruvara dema, zvakakwana kudzima mwenje, unovimbisa "vatema vatema" uye kuwedzera simba kwesimba. Nekuparadzira neiyo yakazara mwenje pani, OLED skrini dzinogara dzakatetepa uye dzinochinjika.

Matambudziko ayo maviri: 1) mutengo wepamusoro, wakapihwa mutengo wepamusoro wekugadzira weOLED skrini kana uchienzaniswa neyakajairwa LED kana LCD; 2) TV ine hupenyu hupfupi.

Samsung, semuenzaniso, inoshoropodza kushandiswa kweOLED skrini mumaterevhizheni uye inoiona yakakosha kune mafoni (ayo anochinja nekukurumidza) achipa sarudzo kune QLED skrini. Avo vanoshandisa OLED tekinoroji mumaterevhizheni LG, Sony uye Panasonic.

QLED

Pakupedzisira, tinouya kuQLED (kana QD-LED, Quantum Dot Emitting Diodes) maTV, imwe gadziriso paLCD, senge LED. Iyi ndiyo yatinodaidza kuti quantum dot skrini: diki zvakanyanya semiconductor particles, ane hukuru husingapfuure nanometer mudhayamita. Haisi itsva seMicroLED, semuenzaniso. Yayo yekutanga yekutengeserana application yaive pakati pe2013.

Mukwikwidzi mukuru weOLED, QLED, inodawo mwenje sosi. Ndiwo makristasi madiki aya anogamuchira simba uye anoburitsa mwenje mafrequency kugadzira mufananidzo pachiratidziri, achigadzira mutsauko wakakura wemavara munzvimbo dzine chiedza chakawanda kana kushoma.

Sony (Triluminos) aive mumwe wemapiyona mukugadzira quantum dot terevhizheni, LG (iyo inodzivirira OLED) inewo masikirini ane tekinoroji iyi. MuBrazil, zvisinei, zvakajairika kuwana akasiyana siyana eSamsung TVs ane QLED skrini.

LG uye Samsung vari kurwira kutariswa kwevatengi. Yekutanga South Korean, LG, inodzivirira: 1) yakanyanya kujeka toni nhema uye yakaderera mashandisiro emagetsi eOLED. Imwe yeSouth Korean, Samsung, inodzivirira: 2) QLED inoratidza mamwe mavara akajeka uye akajeka uye masikirini asingadzivirirwe kune "yakapiswa mhedzisiro" (inowedzera isingawanzo muterevhizheni).

Pasinei nematoni matema akasviba, OLED inogona kuramba ichisiya mamakisi pane inorema skrini vashandisi uye mifananidzo yakamira, yakadai sevatambi vemutambo wevhidhiyo mumakore. Kune rimwe divi, maQLED anogona kuratidza "grey vatema."

Dambudziko rinoitika kunyanya mumaterevhizheni akareruka (verenga zvakachipa). Zviratidziro zvinodhura zvakanyanya (seQ9FN) zvinopa humwe tekinoroji senge dimming yemuno, iyo inovandudza mwenje wekuita pazviratidziro nekudzora backlight kuratidza vatema "vatema". Izvo zvinoita kuti zvive zvakaoma kuvasiyanisa kubva kuOLED.

MICROLED

Chivimbiso chekupedzisira ndeye MicroLED. Iyo tekinoroji nyowani inovimbisa kuunza pamwe chete yakanakisa yeLCD neOLED, ichiunza pamwe chete mamirioni eiyo microscopic maLED anogona kuburitsa iwo ega mwenje. Kuenzaniswa neLCD skrini, kugona kwesimba uye kusiyanisa kuri nani, uyezve, inogona kuburitsa kupenya kwakawanda uye kuva nehupenyu hurefu kupfuura OLED.

Nokushandisa inorganic layer (kusiyana neiyo organic LEDs, iyo inogara zvishoma) uye madiki ma LED, microLEDs, achienzaniswa neOLED, anogona: 1) kupenya uye kugara kwenguva refu; 2) kuve kushoma kana kupisa.

TFT LCD, IPS uye TN skrini: mutsauko

Pane nguva dzose kuvhiringidzika kana nyaya iri skrini, AMOLED kana LCD. Uye, kutarisa zvakanyanya paLCD skrini, kune akati wandei akasanganiswa matekinoroji, akadai seTFT, IPS kana TN. Chimwe nechimwe chezvirevo izvi zvinorevei? Uye mukuita, chii chakasiyana? Ichi chinyorwa chinotsanangura, nenzira yakapfava, chii chinangwa cheiyi tekinoroji.

Kuvhiringidzika kwese uku kunoitika, ndinotenda, nekuda kwekushambadzira uye zvikonzero zvenhoroondo. Muhunyanzvi hwehunyanzvi, vanogadzira kazhinji (haisi mutemo) vanosimbisa iyo acronym IPS mumidziyo ine mapaneru aya.

Semienzaniso: LG, iyo inobheja yakawanda pane tekinoroji (kusiyana neSamsung, yakanangana neAMOLED), inotoisa zvitambi zvinoratidzira IPS pani pane smartphones. Zvakare, iwo akanyanya kuomesesa monitors, akadai seDell UltraSharp uye Apple Thunderbolt Display, ndeye IPS.

Kune rimwe divi, mafoni akachipa agara ari (uye achiripo) akatangwa neinonzi TFT skrini. Sony yaiwanzotora zviratidziro zvakashambadzirwa se "TFT" mumafoni ayo epamusoro-soro kusvika Xperia Z1, iyo yaive nehurombo hwemhando yepamusoro ine kona shoma yekuona zvichienzaniswa nevakwikwidzi vayo.

Sezvineiwo, pakasvika Xperia Z2, yakashambadzirwa se "IPS" uye pakanga pasina kutsoropodza kwakanyanya kwezviratidziro pamafoni eSony anodhura. Saka huya neni.

Chii chinonzi TFT LCD skrini?

Kutanga, tsananguro yeduramazwi: TFT LCD inomirira Thin Film Transistor Liquid Crystal Display. MuChirungu, ndinoshandura izwi risinganzwisisike sechinhu chakafanana ne "thin film transistor based liquid crystal display". Izvo hazvisati zvataura zvakawanda, saka ngatijekese zvinhu.

LCD yaunotoziva zvakanaka, kunyangwe iwe usingazivi kuti inoshanda sei. Iyi ndiyo tekinoroji inonyanya kushandiswa nedesktop yako kana laptop yekutarisa. Chigadzirwa chacho chine inonzi "liquid crystals", izvo zvinhu zvakajeka zvinogona kuita opaque pavanogamuchira magetsi.

Aya makristasi ari mukati mechidzitiro, ine "pixels", inoumbwa nemavara matsvuku, girini uye bhuruu (iyo RGB standard). Ruvara rumwe norumwe runowanzo tsigira 256 toni mutsauko. Kuita maakaunti (2563), zvinoreva kuti pixel yega yega inogona kuumba anopfuura mamirioni gumi nematanhatu emavara.

Asi mavara emakristasi aya emvura anoumba sei? Zvakanaka, ivo vanofanirwa kugashira magetsi kuti ave opaque, uye ma transistors anotarisira izvi: imwe neimwe ine basa repixel.

Kuseri kweLCD screen ndiko kunonzi backlight, chiedza chichena chinoita kuti chidzitiro chipenye. Mumashoko akareruka, funga neni: kana ma transistors ese akadhirowa ikozvino, makristasi emvura anova opaque uye anodzivirira kupfuura kwechiedza (nemamwe mazwi, skrini ichave dema). Kana pasina chinobuda, skrini ichava chena.

Apa ndipo panopinda TFT. MuTFT LCD skrini, mamirioni ematransistors, ayo anodzora imwe neimwe yemapikisheni epaneru, anoiswa mukati meiyo skrini nekuisa firimu rakatetepa rezvinhu zvidiki zvishoma nemanomita kana mamicrometer akakora (tambo yebvudzi iri pakati pe60 uye 120 mamicrometer akakora. ) Zvakanaka, isu tatoziva kuti chii chinonzi "bhaisikopo" riripo mune acronym TFT.

TN inopinda papi?

Kunopera kwezana ramakore rapfuura, anenge ese maTFT LCD mapaneru akashandisa nzira inonzi Twisted Nematic (TN) kushanda. Zita rayo imhaka yekuti, kuitira kuti chiedza chipfuure nepapixel (kureva kuti, kugadzira ruvara ruchena), kristaro yemvura inorongwa muchimiro chakamonyoroka. Iyi graphic inoyeuchidza iyo yeDNA mifananidzo yawakaona muchikoro chesekondari:

Apo iyo transistor inobudisa magetsi emagetsi, chimiro "chinowira pasi." Liquid makristasi anova opaque uye nekudaro pixel inoshanduka dema, kana kuratidza ruvara rwepakati pakati pechena nedema, zvichienderana nesimba rinoshandiswa neiyo transistor. Tarisa pamufananidzo zvakare uye ona nzira iyo makristasi emvura akarongwa: perpendicular kune substrate.

Asi munhu wese aiziva kuti iyo TN-based LCD yaive nezvimwe zvisingakwanisi. Iwo mavara haana kudzokororwa nekuvimbika kwakafanana uye pakanga paine matambudziko nekona yekutarisa: kana iwe usina kunyatsomira pamberi peiyo monitor, waigona kuona kusiyanisa kwemavara. Kuwedzera kunze kwe90 ° angle iwe wakamira pamberi pemonitor, iwo akanyanya kutaridzika mavara.

Musiyano kubva kuIPS mapaneru?

Ipapo imwe pfungwa yakaitika kwavari: ko kana mvura crystal yaisafanira kurongeka perpendicularly? Ndipo pavakagadzira In-Plane Switching (IPS). Mune IPS-yakavakirwa LCD pani, iyo yemvura mamorekuru mamorekuru anorongedzerwa akatwasuka, kureva, anoenderana neiyo substrate. Mune mamwe mazwi, vanogara vari mundege imwechete ("In-Plane", kuiwana?). Mufananidzo wakaitwa naSharp unoratidza izvi:

Sezvo iyo crystal yemvura inogara iri padyo muIPS, iyo yekuona kona inoguma ichivandudza uye kubereka kwemavara kunowedzera kutendeka. Dambudziko nderokuti tekinoroji iyi ichiri kudhura kugadzira, uye havasi vese vanogadzira vanoda kushandisa yakawanda pane IPS pani mukugadzirwa kweiyo inonyanya kukosha smartphone, uko chakakosha kuchengetedza mari shoma.

Pfungwa yakakosha

Muchidimbu, IPS ingori iyo: imwe nzira yakasiyana yekuronga liquid crystal molecules. Izvo zvisingashanduki nekuremekedza TN ndeye transistors, iyo inodzora mapixels: ivo vachiri kurongeka nenzira imwechete, ndiko kuti, yakaiswa se "firimu yakaonda". Hazvina musoro kutaura kuti IPS skrini iri nani pane TFT: zvingaite sekuti "Ubuntu hwakashata kupfuura Linux".

Nekudaro, iyo IPS skrini yaunoziva zvakare inoshandisa TFT tekinoroji. Muchokwadi, TFT inzira yakapamhama kwazvo, iyo inoshandiswa zvakare muAMOLED mapaneru. Icho chokwadi chekuziva kuti pani ndeye TFT haisi kuratidza hunhu hwayo.
