Ibibanza byijimye byagaragaye kuri televiziyo – impamvu zo gukuraho umwijima

Hariho impamvu nyinshi zituma ibibara byirabura byijimye bigaragara kuri TV. Ariko mubihe byinshi, kuboneka kwabo byerekana kwangirika kwa matrix. Kandi ntabwo igomba kuba imashini. Birashoboka ko diffuser yakuweho kubera inenge yakozwe. Kandi rimwe na rimwe ahantu hijimye kuri TV urashobora kuvaho wenyine! Ariko mubihe byinshi, ugomba gushaka ubufasha mubigo byemewe bya serivise.

Impamvu zumukara hamwe nigicucu cyijimye kuri matrise ya TV

Ishingiro rya TV iyo ari yo yose igezweho (kandi ikurikirana nayo) ni matrix. Kandi igizwe nibice byinshi, byumwihariko:

1. Akayunguruzo . Guhindura ihererekanyabubasha ryumucyo utangwa numucyo winyuma.
2. Amazi ya kirisiti . Bakora “ishusho” yanyuma kuri ecran. Ibara rya buri pigiseli igengwa numuriro utanga amashanyarazi.
3. Akayunguruzo ko hanze . Niba ibuze, noneho aho kugirango ishusho kuri ecran hazaba hari ibara ryijimye gusa. Nubwo urwego rwamazi ya kirisiti, kimwe numucyo winyuma, bikora neza.

Kandi inyuma ya matrix hari urumuri rwa LED. Bishyizwe hejuru yindege yose ya diagonal ya TV. Nibisanzwe, iyi ni umurongo wa LED, aho buri kintu gihujwe kuburinganire (muri TV zimwe bibaho murukurikirane, ariko iki gishushanyo ntabwo gikoreshwa ubu).

Kandi LED nayo ifite ibikoresho byayo bwite (ugereranije – kuva kumasaha 30 kugeza 50.000).

Kubera iyo mpamvu, impamvu nyamukuru zikurikira zatumye ibibara byijimye bigaragara kuri TV ya LCD bishobora gutandukanywa:

• pigiseli “yamenetse” ;
• kwangiza imashini;
• kunanirwa kwimikorere yinyuma (igizwe neza n’amatara ya LED, kimwe na inverter ihindura amashanyarazi cyangwa igenga voltage yayo);
• gutatanya inenge;
• gutondekanya kimwe mubice bya matrix (polarisation);
• kunanirwa kwa chip ya videwo (gutunganya amashusho, ashinzwe gutunganya ibimenyetso bya digitale, kuyihindura no kuyisohora muri materique ya kirisiti).

“Pikeli ifite inenge

Ishusho muma matrike ya kirisiti igizwe na miniature pigiseli. Kandi hafi 95% yimanza, ahantu hijimye kuri ecran ni ingaruka zibyangiritse. Irasa nudusimba twamabara menshi adafite halo hafi. Ibara ryabo rirashobora kuba hafi: ubururu, icyatsi, umukara, umweru, umutuku. Kubwamahirwe, gusenyuka ntigushobora gusanwa, cyane cyane wenyine. Ariko icyarimwe, ababikora benshi mumabwiriza yo gukoresha berekana neza ko kuba pigiseli nyinshi “zacitse” aribisanzwe. Kurugero, kuri Samsung, niba hari 3 gusa muri ecran, ubwo ntabwo bifatwa nkurubanza rwa garanti. Niba ari byinshi, noneho matrix izasimburwa kubusa. Kubindi bisobanuro birambuye, nyamuneka hamagara uwabikoze mu buryo butaziguye.

Niki gitera pigiseli “yamenetse” kugaragara kuri ecran ya LCD?

Abahanga bavuga ko zishobora guterwa no kwangirika kwa televiziyo (ingaruka kuri matrix), cyangwa kugabanuka k’umuvuduko utunguranye (cyane cyane kurenza agaciro kemewe, hejuru ya 230 – 250 Volts). Kubwibyo, niba umuyoboro uri murugo umuyagankuba udahagaze neza, noneho birasabwa guhuza TV binyuze mumashanyarazi yo hanze – ibi rwose bifasha kwagura ubuzima bwibikoresho.

Matrix yangiritse

Akenshi usanga bisa nkibara ryirabura kuri ecran ya TV ifite impande zingana.

Bibaho na nyuma yo gukubitwa byoroheje kuri matrix cyangwa TV!

Yerekana uruziga rufunguye rutanga imwe mumazi ya kristu. Ntibishoboka gusana ibyo gusenyuka. Hama hariho akaga ko ibibanza nkibi bizokwiyongera mubunini mugihe. Nukuvuga, hamwe nibishoboka 95%, matrix izahita idakoreshwa. Twabibutsa kandi ko gukoresha TV ifite matrike yangiritse ku buryo bwa tekinike ntabwo ari igitekerezo cyiza. Hano haribishoboka ko habaho umuzunguruko mugufi hagati yumuzunguruko wa matrix, bizanatuma habaho kunanirwa kwa inverter, cyangwa na GPU. Gusana ibyo gusenyuka ntibishoboka. Nukuvuga ko, mugihe kizaza ugomba kugura TV nshya kugirango usimbuze iyakera.

Kunanirwa kwimikorere yinyuma

Hariho uburyo 2 butandukanye bwo gusenyuka:

1. Kunanirwa kwa LED ubwayo . Nukuvuga ko igice cya kabiri kirimo, corny yatwitse. Ntibishoboka gusimbuza, muri serivise zitanga gusa gusimbuza byuzuye imirongo yose ya LED-inyuma. Ariko ubu ni inzira ihendutse.
2. Kunanirwa kwa inverter, ishinzwe gutanga amashanyarazi kumurongo winyuma . Muri iki kibazo, LED irashobora kubanza kudakora muri zone runaka (urugero, mugice cyo hejuru cyibumoso). Ariko mugihe kizaza, utundi turere twaka amatara byanze bikunze tuzaba dufite ingufu.

Irasa cyane na zone yijimye hamwe na halo ihuye aho kuba umwijima utandukanye. Ariko icyarimwe, niba urabagirana urumuri rukomeye mugice cyijimye, uzabona ko ishusho igaragara mubisanzwe kuri materique ya kirisiti. Ntabwo bimurika. Ntugomba gukora ikintu wenyine, nibyiza kuvugana na serivise yemewe kugirango igufashe vuba bishoboka. Twabibutsa kandi ko niba itara ryinyuma ryangiritse, rishobora rimwe na rimwe gukira ryonyine. Ariko iyi ningaruka zigihe gito. Nibindi byemeza gusa ko hari ukurenga kumurongo utanga imirongo ya LED.

Gukwirakwiza inenge

Uhereye imbere, isahani ya plastike ya TV inyuma yometseho urwego rwihariye rwo gutatanya, bigaragara neza nkicyuma gisanzwe. Ifite inshingano yo kwerekana urumuri rukubita ruva inyuma ya LED, kimwe no murwego rwa polarisiyasi (rugaragaza urumuri rugwa kuri rwo). Niba kandi hari ahantu heza, harangiritse, gukuramo ibice bikora kumurongo utatanye, noneho ibi bisa nkibintu byijimye kuri ecran. Nukuvugako, akenshi inenge igaragara nyuma ya matrix isanwe mubigo bya serivisi bitemewe. Kuberako ngaho ibice bitatanye byandikishijwe intoki, ni ukuvuga, ntibishoboka ko umuntu agera ku bworoherane bwuzuye no kubura kunama no kugundura. Mubigo byemewe bya serivise, nkitegeko, igifuniko cyinyuma cyose cyasimbuwe, kuriyo gutatanya bikoreshwa no muruganda. Kubwibyo, birashoboka ko gusana ubuziranenge buringaniye.

Gusiba firime ya polarizing

Ibi bibara byijimye kuri ecran ya TV birashobora gufata uburyo ubwo aribwo bwose. Kenshi na kenshi – bazengurutswe, bafite impande zingana, kimwe n’imirongo. Ariko hamwe nigitutu gito, ishusho irashobora kuba mugihe gito, nkuko hamwe na matrix ikora byuzuye. Yerekana ko firime ya polarizing yacitse. Kandi ibi bibaho bitewe no kwangirika kwa mashini, cyangwa bitewe no gukoresha ibicuruzwa byogusukura bikabije kugirango uhanagure ecran ya TV. Ntibisanzwe – kubera ubukwe bwuruganda. Muri tereviziyo zishaje, haracyari ikibazo mugihe filime ya polarisiyonike yabayeho kubera ubushyuhe bukabije bwa matrix. Bitewe n’ubushyuhe bwo hejuru, kole yashonga gusa! Ibi akenshi biterwa nuko TV ishyirwa hafi yurukuta cyangwa ubushyuhe (kandi ntibukonje neza). Kubikosora ubwawe ntibishoboka.

Kunanirwa kwa videwo

Kimwe mu bidakunze kubaho kandi icyarimwe bigoye gusenyuka. Chip ya videwo ahanini irananirana kubera ubushyuhe bukabije cyangwa inenge zuruganda. Muri iki kibazo, ibihangano bitandukanye, ibibara hafi yamabara yose bishobora kugaragara kuri ecran. Ariko nta shusho isanzwe cyangwa ibishushanyo mbonera bishobora kuboneka muburyo ubwo aribwo bwose. Televiziyo isubiza gusa kuyizimya no kuzimya “kuva hanze”, kubera ko kuri tereviziyo zigezweho ndetse n’ibimenyetso biva mu mashanyarazi bitangwa na GPU. Uku gusenyuka nako gukurwaho gusa mubihe bya serivise. Kandi harikibazo ko bitazashoboka gukosora TV, kubera ko chip ya GPU itaboneka kubintu byose (bitewe na politiki yimbere yabayikoze, ndetse no kuboneka ibikoresho byabigenewe).

Impamvu Zinyongera Zitera Ahantu Hijimye Kumurongo wa TV zitandukanye

Ihame, ibitera ibibanza kuri TV hafi ya byose ni bimwe, kubera ko imiterere ya matrix nihame ryo kwerekana ishusho birasa. Ariko hariho ibitari bike:

1. Kuri TV za Samsung hamwe na matrices ya AMOLED, ibibara byijimye bishobora kwerekana matrix “gutwika”. Nta kumurika inyuma, kuko buri pigiseli ni tekiniki LED. Mugihe kimwe, ibibanza bisa nkibikurikira (bakunze kwita “abazimu”).
2. Ahantu hijimye kuri ecran ya TV TV rimwe  na rimwe ni ibisubizo bya software! Byukuri, kubera kurenga kuri tekinoroji ya code ya AVI na MPEG4. Mubihe nkibi, ivugurura ryibikoresho bya banal ukoresheje ibikoresho byubatswe na TV ubwayo bifasha. Hamwe niki kibazo, ibibara byijimye bigaragara ahantu hatandukanye igihe cyose ubifunguye, nta gahunda yikurikiranya.

Ibyo ushobora gukora murugo kugirango ukosore smudges na blackout kuri TV yawe yubwenge

Mubihe bidasanzwe cyane, ibibara byijimye bicika bonyine mugihe runaka. Ibi bibaho niba bigaragara kubera gusibanganya urwego rwa polarisiyasi hamwe n’ubushyuhe buke bwa matrix. Ariko ibi ni 0.5% byimanza zose. Mu bindi bihe, birasabwa gusura ikigo cya serivisi. Kandi byihuse, nibyiza. Nigute ibyago byo kwandura bishobora kugabanuka? Ibyifuzo bikurikira bigomba gukurikizwa:

• nuburyo ubwo aribwo bwose bushoboka kugirango uringanize ibyangiritse kuri TV (urugero, niba murugo hari abana bato, noneho nibyiza gushyira TV kurukuta hejuru yuburebure bwa metero 1.5 – 1,7);
• ntugashyire TV hafi yurukuta (byibuze indent isabwa, abayikora bagaragaza mumabwiriza yabo, ni santimetero 15);
• ntugashyireho urumuri rwinshi rwurumuri rwinyuma (mubihe byinshi ibi ntibisabwa, kandi 50 – 70% byurumuri rworoshye biroroha kubareba benshi);
• huza TV unyuze mumashanyarazi yo hanze (bizagabanya amahirwe yo kunanirwa kwa inverter hamwe nubushakashatsi).

_ ikigo cya serivisi. Muri icyo gihe, shobuja akeneye gusobanura mubihe inenge yagaragaye, ibyabaye mbere yibi. Niba gusimbuza byuzuye matrix ari \ u200b \ u200bidakenewe, noneho ibi bizatwara hafi 30 – 70% yikiguzi cya TV nshya (bitewe nurugero rwihariye). Niba ikibazo kiri mubishushanyo mbonera, noneho kuyisimbuza igura hafi 30 – 50% yikiguzi cya TV, ariko shobuja ntabwo buri gihe abasha kubona igice cyabigenewe.
