Yadda ake duba matattun pixels akan TV lokacin siye da a gida

Yadda ake duba matattun pixels akan TV – yadda ake gano matattun pixels da fitilun da ba na halaye ba lokacin siye a cikin shago da hanyoyin gwaji da dubawa a gida. Nunawa a kan Talabijin shine mafi rikitarwa zane, wanda sau da yawa karya daidai a masana’anta ko a cikin kantin sayar da. Saboda wannan, yana da daraja sanin game da babban matsalar duk matrices a cikin TV – pixels karya. Wannan labarin zai tattauna abin da yake, yadda za a gane su, kuma a cikin wane yanayi za ku iya gyara shi da kanku.

Menene mataccen pixel akan Smart TV, yaya yake kallon gabaɗaya

Kowane nuni yana nuna hoto ta amfani da pixels – waɗannan LEDs guda ɗaya ne waɗanda ke haskakawa da wani haske. Babban adadin su yana haifar da tasirin hoto mai motsi. Suna aiki ba tare da juna ba kuma ana sarrafa su ta mai sarrafawa. Kowane pixel yana da ƙananan pixels – waɗannan su ne kwararan fitila na RGB na ja, kore da shuɗi. Idan ka haskaka waɗannan launuka guda uku daban-daban, za ka iya samun kowane launi daga bakan da ake iya gani ga mutum. Idan kun haskaka dukkan launuka uku, kuna samun fari, kuma idan kun kashe – baki. Ta haka ne aka kafa hoton.
Idan pixel ya lalace, ba zai kashe duk na’urar ba, amma zai haifar da digon duhu akan allo a wuri guda. Wasu batutuwa tare da pixel na iya sa shi ya yi haske a launi ɗaya ko a kashe koda hoton baƙar fata ne. Saboda haka, lokacin kallon bidiyo, za a sami lahani mai launi a lokaci ɗaya, yana kama da haka:

Wadanne nau’ikan matattun pixels suke akan TV

Pixel na iya yin halin rashin tabbas saboda dalilai iri-iri, daga kera tanadin farashi zuwa lahani na jiki yayin jigilar kaya. Kamar wancan, pixels ba zai iya karya ko da bayan shekaru da yawa na aiki. Akwai manyan nau’ikan matattun pixels guda uku, wato:

1. Farin tabo (mafi shaharar suna shine pixel mai zafi). Irin wannan pixel yana da matsala tare da mai sarrafawa, baya fahimtar umarnin samar da wutar lantarki kuma yana samar da matsakaicin halin yanzu. Saboda wannan, pixel yana ƙonewa zuwa matsakaicin, kuma wannan yana haifar da hoton fari. Irin wannan pixel koyaushe yana haskaka fari mai haske.
2. Baƙar digo . Wannan mataccen pixel ne, ko dai yana iya ƙonewa ko a’a karɓar umarni daga mai sarrafawa kuma koyaushe yana kashewa.
3. Digon launi (suna na biyu pixel makale ne). Irin wannan yana samuwa ne lokacin da ɗaya daga cikin ƙananan pixels (ja, koren ko shuɗi mai haske) ya kasa. A wannan yanayin, pixel ba zai iya haɗa launukan RGB akai-akai ba, wanda shine dalilin da ya sa koyaushe yana haskakawa cikin launi ɗaya, ko kuma an canza lafazin sa zuwa ɗayan palettes (misali, yakamata a sami haske kore, amma akan nuna rawaya ne). Za’a iya gyara irin wannan lalacewar da kanka.

Yadda ake gane pixels da ya karye akan TV tare da matrices daban-daban

Yana da daraja la’akari da cewa akwai manyan nau’ikan matrices guda biyu, wato nunin LCD da OLED. A ainihin su, suna aiki iri ɗaya, amma OLEDs har yanzu suna da saurin ƙonewa a cikin pixel, wanda shine lokacin da hoton ya kasance akan allon idan an ciyar da shi zuwa TV na dogon lokaci. Irin wannan lahani yana bayyana ta hanyar shimfiɗa hoto ɗaya akan wani. Fuskokin LCD ba su da wannan fasalin, don haka sun fi ɗorewa. Akwai nau’ikan matrices na LCD da yawa (ruwa crystal matrices), amma nau’ikan su ba sa shafar hanyar samun matattun pixels, ƙaddara da gyara su. Idan TV tana da IPS, QLED ko Nano Cell matrix, to wannan matrix LCD ne.

Muhimmanci! Wasu masana’antun ko kantuna wani lokaci suna jera nau’in allo na LED. A matsayin hanyar hasken baya, a zahiri, waɗannan su ne ma’aunin IPS na yau da kullun.

Bugu da ari a cikin labarin, za mu bincika yadda ake ganowa da gyara fashewar pixels akan TV a gida ko mayar da shi ƙarƙashin garanti.

Matattun pixels nawa aka yarda akan nau’ikan matrix daban-daban

Idan pixels da suka karye sun bayyana akan TV, zaku iya mayar da shi cikin shagon ƙarƙashin garanti (ba shakka, idan har yanzu bai ƙare ba). Amma ba duk lahani tare da matrices ana ɗaukar matsayin garanti ba; a wasu yanayi, ana iya hana gyarawa. Saboda rikitarwar yin allo, masu gudanarwa sun fito da ma’auni wanda ke daidaita wasu ƙarancin masana’anta kuma yana ba da damar ƙaramin adadin matattun pixels a ɗauka na al’ada ba ƙarƙashin garanti ba. Kamar yadda muka gano a baya, akwai matattun pixels iri uku. Kowannen su an tsara shi daban. Dukkanin talabijin sun kasu kashi hudu na fasaha, mafi girman ajin, mafi kyawun matrix da abubuwan da ake bukata don shi sun fi tsayi. Anan ga matakan da aka raba matrices a cikin talabijin na zamani:

1. Ajin farko – bai kamata a sami matattun pixels ba kwata-kwata, ko mafi ƙarancin lambar su, babban lamba ana ɗaukar lahani kuma garanti ya rufe shi. Yana faruwa ne kawai a cikin samfura masu tsada sosai.
2. Ajin na biyu shine matrices masu inganci, wanda ya zama al’ada don samun dozin matattun pixels. Yawanci na na’urori masu tsada.
3. Nau’in aji na uku shine mafi shaharar nau’in ajin, wanda aka baiwa mafi yawan nau’ikan tsarin kasafin kudi. Ana ba da izinin ƙananan matattun pixels, waɗanda ba a iya gani a rayuwa ta ainihi.
