Tsarin Yin Talabijin Mai Girman Allo
Talabijin masu manyan allo—daga inci 55, inci 65, inci 75, har ma da sama da inci 85—yanzu sun zama ruwan dare gama gari saboda suna ba da ƙwarewar kallo mai zurfi. Duk da haka, a bayan siraran allo da hoto mai kaifi, akwai doguwar hanyar kera kayayyaki da ta ƙunshi fasahar zamani. Yin babban talabijin ba wai kawai batun haɗa kayan aiki ba ne; ya ƙunshi matakai da dama, tun daga ƙirƙirar allon allo da shigar da da'irori na lantarki zuwa daidaita launi da kuma gwada inganci mai tsauri. Ga cikakken bayani game da tsarin kera talabijin mai manyan allo.
1. Tsarin Samfura da Zane
Matakin farko yana farawa da tsara takamaiman samfura. Masana'antun suna tantance nau'in fasahar nuni da za a yi amfani da ita—misali, LED-LCD, QLED (quantum dot LCD), OLED, ko Mini LED. Wannan shawarar tana da tasiri sosai ga tsarin allon, buƙatun hasken baya, amfani da wutar lantarki, har ma da kauri na talabijin.
A lokacin tsarin ƙira, ƙungiyar injiniya tana haɓaka ƙirar injina (kauri a jiki, firam ɗin tallafi, wuraren ɗorawa, sanya tashar jiragen ruwa), ƙirar lantarki (babban allo, samar da wutar lantarki, ɓangaren direba), da ƙirar software (tsarin aiki, tallafin aikace-aikace, firmware). Ga manyan talabijin, ƙarfin firam da kwanciyar hankali na panel suna da mahimmanci, saboda faɗin girma yana ƙara haɗarin lanƙwasa panel ko fuskantar matsin lamba mara daidaituwa.
2. Yin Allon Nuni
Allon nuni shine "zuciyar" talabijin, kuma shine mafi tsada da wahalar ƙera. Tsarin ya bambanta dangane da fasahar:
a) Faifan LCD (LED TV/QLED/Mini LED)
LCDs ba sa fitar da hasken kansu. Suna buƙatar hasken baya. Ana ƙera bangarorin LCD a cikin kayan aikin semiconductor na musamman (ɗakuna masu tsabta) saboda ko da ƙaramin ƙura na iya haifar da lahani ga pixels.
Manyan tsare-tsare sun haɗa da:
– Yin gilashin da aka yi da gilashi: ana sarrafa babban gilashi (gilashin uwa) zuwa bangarori da dama.
- Tsarin transistor mai sirara (TFT): an saka wani siririn Layer na kayan semiconductor a cikin gilashi don samar da matrix mai sarrafa pixel.
– Aiwatar da layin lu'ulu'u na ruwa: ana sanya lu'ulu'u na ruwa tsakanin layuka biyu na gilashi tare da kauri mai kyau.
– Shigar da matatun launi (RGB): Ana ƙirƙirar matatun ja, kore, da shuɗi don samar da launi.
– Shigar da Polarizer: wannan Layer yana taimakawa wajen sarrafa alkiblar haske ta yadda LCD zai iya "tsara" ƙarfin kowane pixel.
QLED yana ƙara wani yanki na dot na quantum don ƙara wa launukan haske. Mini LED yana amfani da adadi mai yawa na ƙananan LEDs, wanda ke ba da damar rage haske a cikin gida.
b) Allon OLED
Ba kamar LCD ba, OLEDs suna fitar da haskensu. Kowane pixel na iya kunnawa da kashewa daban-daban, wanda ke haifar da duhu mai zurfi. Tsarin kera OLED ya ƙunshi adana kayan halitta masu kyau, waɗanda ake yi a cikin ɗaki mai tsabta. Allon OLED galibi suna da rikitarwa da kuma saurin amsawa, musamman a manyan girma, suna buƙatar ingantaccen iko.
3. Yin da Shigar da Hasken Baya (na LCD)
Ga manyan talabijin na LCD masu allo, na'urar hasken baya muhimmin bangare ne. Akwai nau'ikan da dama:
– Hasken gefen: LEDs ɗin suna gefen gefen, kuma ana tura hasken ta cikin farantin jagora mai haske. Wannan ƙirar tana ba da damar jiki mai siriri, amma iyakancewar sarrafawa ta gida.
– Hasken kai tsaye / Cikakken tsari: Ana shimfida LEDs a bayan allon. Tare da cikakken tsari na dimming na gida (FALD) ko Mini LED, yankunan sarrafa haske sun fi girma, suna ƙara bambanci.
Hasken baya yana ƙunshe da wasu layukan gani:
- Diffuser don daidaita haske,
– Takardar Prism don jagorantar haske gaba,
- Mai nuna haske don ƙara ingancin tunani.
Saboda girman allo mai girma, babban ƙalubalen shine a kiyaye daidaiton haske: dole ne a sami wurare masu haske, duhu, ko tasirin "girgiza".
4. Haɗa Modules na Panel da Frames na Inji
Da zarar an shirya bangarorin, mataki na gaba shine haɗa bangarorin na'ura. Ana ɗora bangarorin a kan firam (chassis), wanda dole ne ya kasance mai ƙarfi amma mai sauƙi. A manyan talabijin, firam ɗin sau da yawa yana amfani da haɗin ƙarfe mai siriri da filastik na injiniya don tabbatar da cewa yana da ƙarfi kuma yana tsayayya da lanƙwasawa.
A wannan matakin:
- shigar da yadudduka masu kariya,
- shigar da bezel (firam) idan ƙirar har yanzu tana amfani da firam,
- shigar da maƙallan ciki don tallafi da wuraren VESA (haɗa bango).
Manyan allunan nuni suna da matuƙar saurin kamuwa da matsi da karkacewa. Saboda haka, sarrafawa yana buƙatar amfani da injin tsabtace injin, safar hannu na musamman, da kuma saman aiki mai hana tsatsa.
5. Haɗa Lantarki: Babban Allo, T-Con, da Wutar Lantarki
Talabijin na zamani kamar kwamfutocin da ke da manyan allo ne. Manyan abubuwan da ke cikinsa sun haɗa da:
– Babban allo: cibiyar sarrafa sigina, tana gudanar da tsarin aiki na TV, tana sarrafa shigarwar HDMI, Wi-Fi, Bluetooth, mai gyara, da kuma na'urar tantance bidiyo.
– T-Con (Mai Kula da Lokaci): yana daidaita lokacin siginar zuwa ga allon ta yadda kowane pixel zai nuna bayanai daidai.
– Na'urar samar da wutar lantarki (PSU): tana mayar da wutar lantarki ta AC zuwa DC mai ƙarfi ga sassa daban-daban na TV.
– Na'urorin sauti da lasifika: gami da amplifiers da direbobin lasifika.
- Masu haɗawa da tashoshin jiragen ruwa: HDMI, USB, LAN, eriya, sauti na gani, da sauransu.
Ana yin haɗakarwa ta amfani da hanyoyin ESD (electrostatic discharge) don hana lalacewar kayan aiki masu mahimmanci. Ana sanya kebul masu sassauƙa (FPC/FFC) a hankali saboda haɗin panel ɗin suna da rauni sosai.
6. Shigar da Firmware da Tsarin Aiki
Da zarar an shigar da kayan aikin, TV ɗin yana buƙatar firmware da tsarin aiki don aiki. Masu kera suna shigar da:
- firmware don bangarori da masu sarrafawa,
- tsarin aiki (misali wasu dandamali na TV mai wayo),
- ƙa'idodi da aka gina a ciki, saitunan yanki, harshe,
- saitin sarrafa inganci na farko.
A wannan matakin, ana kuma gudanar da gwaje-gwajen ayyuka na asali: dole ne TV ɗin ta iya kunnawa, nuna hotuna, samar da sauti, karanta na'urar nesa, da kuma gane shigarwar.
7. Daidaita Hoto da Saitunan Launi
Daidaita abubuwa muhimmin mataki ne, musamman ga talabijin masu inganci. Wannan tsari ya ƙunshi kayan aiki kamar na'urar auna launi ko na'urar aunawa don tabbatar da cewa:
- daidaiton fari,
- daidaiton launi (gamuwar launi da kuskuren delta),
- gamma da bambanci,
- daidaiton haske,
- gyara don hasken baya na gida (akan FALD/Mini LED),
- duba lahani na pixel.
A manyan talabijin, daidaiton tsari babban ƙalubale ne saboda babban yanki yana sa a ga kurakurai a bayyane. Saboda haka, wasu masana'antun suna daidaita kowane naúra ko kowane rukuni na samarwa zuwa takamaiman haƙuri.
8. Gwajin Inganci da Inganci (Sarrafa Inganci)
Kafin a saka talabijin a cikin na'urar, ana yin gwaje-gwaje daban-daban:
– Gwajin ƙonewa: Ana kunna talabijin na tsawon lokaci don duba daidaiton allon da na'urorin lantarki.
- Gwajin zafin jiki da danshi: yana tabbatar da cewa TV ɗin yana ci gaba da aiki a cikin yanayi daban-daban na muhalli.
- Gwajin tashar jiragen ruwa da haɗi: HDMI, USB, Wi-Fi, Bluetooth, eARC, da mai gyara.
- Gwajin sauti: duba lasifika, murdiya, daidaitawar sauti da bidiyo.
- Gwajin jiki: ƙarfin firam ɗin, maɓallan, tashoshin jiragen ruwa, da kuma duba lahani na kwalliya.
Talabijin da ba su wuce ba za su shiga hanyar gyara (gyara) ko kuma a ƙi su bisa ga ƙa'idodin kamfani.
9. Haɗawa da Marufi na Kayan Haɗi
An samar da kayan haɗi kamar na'urar sarrafawa ta nesa, batura, igiyar wutar lantarki, wurin tsayawa, sukurori, da littafin jagorar mai amfani. Ga manyan talabijin, an tsara marufin don jure girgiza. Amfanin da aka saba amfani da su sun haɗa da:
- kumfa mai kariya,
- kwali mai kauri mai layi,
- mai kare allo,
- alamar matsayi na "sama-ƙasa" don hana shi juyewa yayin jigilar kaya.
Saboda manyan bangarori suna fuskantar barazanar fashewa saboda matsin lamba, hanyoyin sufuri da ajiya suma suna bin wasu ƙa'idodi, gami da iyakokin tara kaya da matsayin sanya su.
10. Rarrabawa da Dubawa na Ƙarshe a Kasuwa
Bayan sun bar masana'antar, ana jigilar talabijin zuwa cibiyoyin rarrabawa da shaguna. Wasu masana'antun ko masu rarrabawa suna yin ƙarin bincike, musamman don na'urori masu inganci. A wannan lokacin, talabijin ɗin sun shirya don masu amfani su karɓa da shigar da su a gidajensu.
Penutup
Tsarin kera talabijin mai manyan allo ya haɗa fasahar kayan aiki, kera daidai, kayan lantarki, da software. Daga ƙirƙirar allon daki mai tsabta da haɗa hasken baya ko na'urar OLED zuwa haɗa firam da da'ira, ta hanyar daidaita launi da gwajin juriya, ana aiwatar da kowane mataki zuwa mafi girman ma'aunin inganci. Girman allon, mafi girman ƙalubalen kiyaye allon da ke da faɗi, har ma da haske, da kuma aikin hoto mai daidaito. Saboda haka, ba abin mamaki ba ne cewa talabijin mai manyan allo suna buƙatar tsauraran hanyoyin samarwa da farashi mai yawa - daidai da ƙwarewar kallon da suke bayarwa.
