Indlela yokwenza isiboniso se-LED ngaphezulu-inkcazo ephezulu

Umboniso okhokelwayo ufumene ingqalelo ebanzi ukususela ekuzalweni kwawo. Ngenkqubela phambili eqhubekayo yofakelo lwetekhnoloji kwiminyaka yakutshanje, sele iqatshelwe kwaye isetyenziswa kumashishini ahlukeneyo. Ukuveliswa kunye nokugcinwa komboniso okhokelwayo nako kufuna ulwazi lobungcali. Indlela yokufezekisa umboniso ophezulu wenkcazo? Ukufezekisa umboniso ophezulu, kufuneka kubekho izinto ezine: okokuqala, umthombo wefilimu ufuna i-HD epheleleyo; okwesibini, umboniso kufuneka uxhase i-HD epheleleyo; okwesithathu, i-dot pitch yesiboniso se-LED iyancitshiswa; kwaye okwesine kukudibanisa umboniso we-LED kunye neprosesa yevidiyo.
1. Ukuphucula umlinganiselo wokuchasana kwesikrini sokubonisa umbala ogcweleyo we-LED yenye yezinto eziphambili ezichaphazela umphumo wokubonwayo. Ngokuqhelekileyo, okukhona umlinganiselo wokuchasana uphezulu, kokukhona umfanekiso ucace ngakumbi kwaye umbala uqaqambile. Umahluko ophezulu unceda kakhulu ukucaca komfanekiso, ukusebenza kweenkcukacha, kunye nokusebenza kwegreyscale. Kweminye imiboniso ebhaliweyo kunye nevidiyo enomahluko omkhulu omnyama nomhlophe, isiboniso se-LED esinombala ogcweleyo sinobuhle kumbala omnyama nomhlophe, ubukhali, kunye nokuthembeka. Umahluko unempembelelo enkulu kwisiphumo somboniso wevidiyo eguqukayo. Ngenxa yokuba ukukhanya nobumnyama kwimifanekiso eguquguqukayo ikhawuleza kakhulu, okukhona umahluko uphezulu, kokukhona kulula emehlweni abantu ukwahlula inkqubo enjalo yotshintsho. Ngapha koko, ukuphuculwa komlinganiselo wokuchasana kwesikrini se-LED esinemibala egcweleyo ikakhulu kukuphucula ukuqaqamba kwesiboniso se-LED esinemibala egcweleyo kunye nokunciphisa ukubonakaliswa komphezulu wesikrini. Nangona kunjalo, ukukhanya akukona kakhulu kunokwenzeka, kuphezulu kakhulu, kodwa kuya kuba yinto echaseneyo, kungekhona nje ukuchaphazela ubomi bokubonisa i-LED, kodwa kubangele ukungcola kokukhanya. Ungcoliseko lokukhanya luye lwaba ngumxholo oshushu ngoku, kwaye ukukhanya okuphezulu kuya kuba nefuthe kwindalo kunye nabantu. Iphaneli ye-LED enombala ogcweleyo kunye ityhubhu ekhupha ukukhanya kwe-LED iphantsi kwenkqubo ekhethekileyo, enokunciphisa ukubonakaliswa kwephaneli ye-LED kwaye iphucule umahluko wombala ogcweleyo we-LED.

2. Phucula inqanaba elingwevu lomboniso we-LED wombala ogcweleyo Inqanaba elingwevu libhekisa kwinqanaba lokuqaqamba elinokwahlulwa ukusuka kowona mnyama ukuya kowona uqaqambe ngokuqaqamba kombala omnye wescreen esinombala ogcweleyo we-LED. Umgangatho ongwevu weI-SandsLED egcwele umbala ogcweleyo umboniso we-LEDiphezulu. Ephakamileyo, umbala ocebileyo, umbala oqaqambileyo; ngokuchaseneyo, umbala wokubonisa ungatshatanga kwaye utshintsho lulula. Ukuphuculwa komgangatho ongwevu kunokuphucula kakhulu ubunzulu bombala, ukwenzela ukuba umgangatho wokubonisa umbala womfanekiso unyuke ngejometri. Inqanaba lolawulo lwe-LED greyscale yi-14bit ~ 16bit, eyenza ukuba iinkcukacha zomgangatho womfanekiso kunye neziphumo zokubonisa iimveliso ezibonisa isiphelo esiphezulu zifikelele kumgangatho ophezulu wehlabathi. Ngophuhliso lwetekhnoloji ye-hardware, isikali se-LED esingwevu siya kuqhubeka siphuhlisa ukuya kulawulo oluchanekileyo.

3. Ukunciphisa i-dot pitch yesiboniso se-LED esinombala ogcweleyo Xa usiba ncinci i-pitch yechaphaza yesiboniso se-LED esinombala ogcweleyo, kokukhona siceketheke ngakumbi isikrini. Nangona kunjalo, le ngongoma kufuneka ixhaswe yiteknoloji ekhulileyo. Ixabiso layo lokufaka lilikhulu ngokwentelekiso, kwaye ixabiso lomboniso ogcweleyo we-LED ovelisiweyo nawo uphezulu. Ngethamsanqa, imakethi ngoku iphuhlisa kwimiboniso ye-LED encinci.

4. Idibaniso ye-LED egcweleyo yombala wesikrini kunye neprosesa yevidiyo Iprosesa yevidiyo ye-LED ingasebenzisa i-algorithms ephuculweyo yokuguqula isignali kunye nomgangatho womfanekiso ombi, yenza uluhlu lwenkqubo efana ne-de-interlacing, i-edge sharpening, imbuyekezo yokunyakaza, njl. , ukuphucula umgangatho womfanekiso. iinkcukacha kunye nokuphucula umgangatho womfanekiso. I-algorithm yokulinganisa iprosesa yevidiyo isetyenziselwa ukuqinisekisa ukuba emva kokuba umfanekiso wevidiyo ulinganisiwe, ukucaca kunye nenqanaba elingwevu lomfanekiso ligcinwa ngowona mlinganiselo mkhulu. Ukongeza, iprosesa yevidiyo nayo ifuna ukuba nokhetho olutyebileyo lohlengahlengiso lomfanekiso kunye neziphumo zohlengahlengiso, kwaye iqhubeke nokukhanya komfanekiso, umahluko, kunye negreyscale ukuqinisekisa ukuba isikrini sikhupha umfanekiso othambileyo nocacileyo.
