Inkinga ye-Mura ebukhwini bombukiso: Ukuqonda, ukuhlola, kanye nezixazululo

Emhlabeni wobuchwepheshe bombukiso, enye yezinkinga ezivame kakhulu futhi ezikhungathekisayo ezingaphakama ubukhona beMura. I-Mura isho ukungalingani noma ukungahambisani nokukhanya, umbala, noma ukuthungwa ngaphesheya kwephaneli yokubonisa. Yinto engaba nomthelela omkhulu ikhwalithi ebonakalayo kanye nesipiliyoni somsebenzisi sesibonisi, ngakho-ke, kubalulekile ukuqonda, ukuvivinya, nokuthola izixazululo zenkinga ye-mura.

Ngomkhiqizi we-LCD noma umkhiqizi we-LCDD Panel, thengisa imibukiso kumakhasimende ngenkinga ye-Mura kuzoba yinhlekelele ngokuphelele, yingakho sidinga ukwazi le nkinga ngaphambi kokuyithumela.

Yini i-mura?

I-Mura, igama lesiJapan elisho "ukungalingani" noma "ukuthungwa okungalingani," yisici esibonakalayo esibonisa njengokungahambi kahle ekufanisweni kwesibonisi. Ingabonakala njengezihlahlana ezimnyama noma ezikhanyayo, ukufikelwa kwamafu, ama-streaks, noma amabala esikrinini. I-Mura ngokuyinhloko okubangelwa ukuhlukahluka kwinqubo yokukhiqiza, njengokwehlukahlukana ngobukhulu noma ubuningi bezingqimba ze-liquid crystal, noma ukungapheleli ezintweni ezibonakalayo.

Ukuhlolwa kwe-Mura:

Ukuhlonza nokucacisa ubukhona be-Mura ekubonisweni, abakhiqizi kanye namaqembu okulawula asezingeni eliphakeme basebenzisa izindlela ezahlukahlukene zokuhlola ezaziwa ngokuhlangene njengezivivinyo ze-Mura. Lezi zivivinyo zihlose ukuhlola ukufana kanye nokuvumelana kokukhipha okubukwayo kokuboniswa. Nawa amanye amasu wokuhlola ama-Mura asetshenziswa kakhulu:

1. Ukuhlolwa okubukwayo: Indlela elula futhi enembile kunazo zonke ukuqinisekiswa okubukwayo ngochwepheshe abaqeqeshiwe abahlola ngokucophelela isibonisi sanoma yiziphi izindlela ezingekho emthethweni. Le ndlela yokuqonda ingasebenza ngempumelelo ekutholeni izinkinga ze-mura ezisobala kepha kungenzeka ingafanele ukukhomba izinkinga ezicashile.

2. Ukuhlaziywa kwezinga elimpunga: Le ndlela ifaka ukubonisa uchungechunge lwamaphethini ezilindwa grey esikrinini bese uhlaziya amanani alinganiselwe we-luminance. Ukuqhathanisa amazinga we-luminance ezifundeni ezahlukahlukene zesibonisi kusiza ukubona noma yimuphi umehluko ohlobene ne-Mura.

3. Ukukhishwa kwesithombe: Ngokuthwebula izithombe zesibonisi ngesendlalelo somfaniswano bese uzikhipha komunye nomunye, noma yimuphi umehluko phakathi kwezithombe ungaqokonyiswa. Izinkinga ze-Mura zizovela njengokuphambuka kusuka ekuhlolweni okulindelekile.

4. Ukulinganiswa kwe-Optical: Ukusebenzisa imishini ekhethekile efana nama-spectroradiometer noma ama-colormeter, izilinganiso ze-optical zingathathwa ngaphesheya kwesibonisi ukuze ubone i-mura. Lezi zilinganiso zinikeza idatha yenhloso ngokuhlukahluka kombala kanye nokuhlukahluka kwe-luminance.

Izinhlobo zezinkinga ze-Mura:

Izinkinga ze-Mura zingabonakala ngezindlela ezahlukahlukene, ngalinye linezimpawu zalo kanye nomthelela ekusebenzeni kokuboniswa. Ezinye izinhlobo ezivamile zezinkinga ze-mura zifaka:

1. Ifu: Amafu abhekisela ekubonakaleni kokukhanya okungemuva kokubukwa, okuphumela emafutheni amafu noma ezindaweni zokukhanya okuhlukile esikrinini. Kuvame ukubangelwa ukungahambisani kwe-backight noma ukuguquguquka okungafanele kokukhanya.

2. I-Banding: Kuvela i-banding njengemigqa evundlile noma eqondile yokukhanya okuhlukahlukene noma ukuqina kombala kulo lonke isibonisi. Imvamisa ibangelwa izikhathi zokuphendula ze-pixel ezingafani noma ukuhlukahluka ku-voltage yokushayela.

3. Ukuchithwa: Ukubona Kubhekiswa Ukuba khona kwamabala amnyama noma akhanyayo esikrinini, esingebangelwa ukungcola kokuqukethwe kwe-crystal noma iziphambeko eziwuketshezi.

4. I-Mura Noise: I-Mura Noise iyigama elisetshenziselwa ukuchaza ukuguquguquka okungahleliwe ekukhazimuleni noma umbala kulo lonke isibonisi. Kungavela ekuhlukahlukani kwama-liquid crystal molecule ukuqondanisa noma amasimu kagesi angafani.

Izisombululo zezinkinga ze-mura:

Ukubhekana nezinkinga ze-Mura kudinga inhlanganisela yokuthuthuka kokukhiqiza, izindlela zokulawula ikhwalithi, nokubonisa amasu wokulinganisa. Nazi ezinye izixazululo ezivamile eziqashiwe embonini:

1. Ukukhiqiza inqubo yokwenza kahle: Abakhiqizi bangahlaziya izinqubo zabo zokukhiqiza ukuze banciphise ukuhlukahluka kwikhwalithi yengxenye, ubukhulu, kanye nobunzima. Lokhu kufaka phakathi ukuthuthukisa ukucaciswa kokuqondanisa kwe-liquid crystal, kuthuthukisa ukufana kwe-backlight, kanye nokunciphisa ukungcola.

2. Ukuhlolwa kokulawulwa kwekhwalithi: Ukuqalisa ukuhlolwa okuqinile kwe-Mura ezigabeni ezahlukahlukene zokukhiqizwa kusiza ukukhomba nokulungisa noma yiziphi izici ezingezona. Lokhu kufaka ukuhlolwa okubukwayo, ukuhlaziya okumpunga, kanye nezilinganiso zokubona ukuqinisekisa ikhwalithi engaguquki.

3. Izingxephezelo ama-algorithms: Abakhiqizi bokubonisa bangathuthukisa ama-algorithms wesinxephezelo aguqula amandla okukhishwayo ukuze anciphise imiphumela ye-mura. Lawa ma-algorithms ahlaziya amaphethini we-mura futhi afake izinyathelo zokulungisa ukuthuthukisa ukufana.

4. Ukubonisa Ukulinganisa: Abasebenzisi bangaqasha amasu wokulinganisa wokubonisa ukwenza kahle ikhwalithi ebonakalayo yokuboniswa kwabo. Lokhu kufaka ukuguqula amapharamitha njengokukhanya, umehluko, nezilungiselelo ze-gamma ukunxephezela noma yimiphi ukungahambisani nokuhlobene okuhlobene.

5. Khombisa amafilimu okuthuthuka okufana: Amafilimu akhethekile angafakwa endaweni yokubonisa ukuze athuthukise ukufana kokuhanjiswa okukhanyayo. Lawa mafilimu asiza ukunciphisa ukukhanya futhi anciphise ukubonakala kokungahambi kahle okuhlobene ne-mura.

Isiphetho:

Inkinga ye-Mura ibeka inselelo ebalulekile emhlabeni we-LCD Display Technology, okuthinta ikhwalithi ebonakalayo kanye nesipiliyoni somsebenzisi sokuboniswa. Ukuqonda umqondo we-Mura, usebenzisa izindlela zokuhlola ezisebenzayo, kanye nokusebenzisa izixazululo ezifanele kuyizinyathelo ezibalulekile ekunciphiseni izindaba ezihlobene ne-Mura. Ngokuthuthukisa izinqubo zokukhiqiza ngokuqhubekayo, ukusebenzisa izindlela zokulawula ikhwalithi, futhi usebenzise amasu wokulinganisa, abakhiqizi bokubonisa nabasebenzisi banganciphisa umthelela we-Mura futhi baqinisekise okuhlangenwe nakho okufana nokubukeka okuthandekayo nokubukeka okuthandekayo.
