Macaamiil badan ayaa la kulma dhibaatooyin badan ama ka yar marka ay iibsanayaan muraayadaha LCD-ga.Sidee loo xalliyaa dhibaatada aberration chromatic ee shaashadda kala qaybinta LCD?Shaashado kala goynta LCD ayaa si weyn loogu isticmaalay warshado kala duwan, laakiin gidaarada kala-baxa LCD waxay weli leeyihiin dhibaatooyin aberration chromatic ah.Guud ahaan, kala duwanaanshaha midabka ee shaashada kala qaybinta LCD waxaa inta badan ka muuqda iswaafaq la'aanta dhalaalka iyo chromaticity ee shaashadda, taas oo ah, qayb ka mid ah shaashadda ayaa si gaar ah u ifaysa ama mugdi ah ama xaalado kale.Iyada oo ku saleysan dhibaatooyinkan, Rongda Caijing LCD soosaarayaasha shaashadda kala qaybinta ayaa halkan u jooga inay wadaagaan dhibaatooyinka aberration chromatic screens LCD iyo xalkooda maanta!
Sababaha aberration chromatic ee shaashadda kala qaybinta LCD
Aberration Chromatic: Aberration Chromatic, oo sidoo kale loo yaqaan aberration chromatic, waa cillad halis ah oo ku jirta sawirka muraayadda.Kala duwanaanshaha midabka ayaa si fudud u ah farqiga midabka.Marka iftiinka polychromatic loo isticmaalo isha iftiinka, iftiinka monochromatic ma soo saari doono aberration chromatic.Qiyaasta hirarka dhererka iftiinka muuqda waa qiyaastii 400-700 nanometer.Mawjadaha dhaadheer ee kala duwan ee iftiinka ayaa leh midabyo kala duwan, waxayna leeyihiin tilmaameyaal dib u celineed oo kala duwan marka la dhex maraayo muraayadda, si dhibic dhinaca shayga ah ay u sameyso dhibic midab ah dhinaca sawirka.Aberration chromatic guud ahaan waxaa ka mid ah aberration chromatic mawqif iyo weynayn aberration chromatic.Aberration chromatic mawqifku wuxuu keenaa dhibco midab leh ama halos inay soo baxaan marka sawirka meel kasta laga eego, taasoo ka dhigaysa sawirka mid blush ah, iyo waynaynta aberration chromatic waxay ka dhigtaa sawirku inuu u muuqdo geeso midab leh.Shaqada ugu weyn ee nidaamka indhaha waa in la baabi'iyo aberration chromatic.
Iswaafajin la'aanta dhalaalka iyo chroma ee shaashadda kala-baxa waxay keeni doontaa dhalaal xumo iyo chroma shaashadda, badanaa waxay muujisaa in qayb ka mid ah shaashadda ay si gaar ah u dhalaalayso ama gaar ahaan mugdi, taas oo ah waxa loo yaqaan 'mosaic and blurry phenomenon'.
Shakhsi ahaan, sababaha kala duwanaanshaha dhalaalka iyo midabka ayaa inta badan sabab u ah kala-soocida dabiiciga ah ee sifooyinka jireed ee LED-yada, taas oo ah, sababtoo ah habka wax soo saarka, cabbirada sawir-qaadista ee LED kasta ma noqon karaan kuwo isku mid ah, xitaa gudaha Dufcaddii isku mid ah, dhalaalku wuxuu noqon karaa 30% -50% leexasho, faraqa hirarka dhererka guud ahaan wuxuu gaaraa 5nm.
Sababtoo ah LED-ku waa jir iskiis u iftiimaya.Xoogagga iftiimayana waxay la mid yihiin ta hadda lagu keenay xad go'an.Sidaa darteed, habka naqshadaynta wareegga, wax-soo-saarka, rakibidda iyo nadiifinta, farqiga dhalaalka waa la yareyn karaa iyada oo si macquul ah loo xakameynayo darawalnimada hadda.Ku xisaabi celceliska qiimaha sida qiimaha caadiga ah.Waa in uu ka yar yahay 15%-20%.
Xalka LCD kala-baxa aberration chromatic screen
Waxaan ka hadalnay sababaha keena kala-baxa chromatic-ka ee shaashadaha kala-baxa ee LCD.Marka, haddii shaashadaha kala-baxa LCD ay leeyihiin cillado chromatic ah oo la isticmaalo, sidee loo xalin karaa?
Dhibaatada ugu weyn ee ay la kulmaan alaabooyinka kala-baxa LCD waa inay soo bandhigaan midabyo kala duwan oo LCD ah.Caadi ahaan marka laga hadlayo arrimaha kala duwanaanta midabka, farsamayaqaanadu waa inay mid mid u hagaajiyaan daraasiin bandhigyo ah, taas oo aan qaadan waqti iyo dadaal, laakiin sidoo kale waxay la kulmaan dhibaatooyin badan, sida la'aanta halbeegga tixraaca midabka midaysan, daalka aqoonsiga muuqaalka, iyo midabka. saamaynta waxqabadka bandhigyo kala duwan.Dhibaatooyin kala duwan iyo kuwo kale oo badan.Natiijo ahaan, wakhtiga iyo xoogga shaqada ayaa inta badan daalan, laakiin dhibaatada kala duwanaanshaha midabka ee bandhigyada kala-baxsan ayaa weli jira.
Farqiga mawjadda dhererka ee u dhexeeya LED-yada, dhererka mawjadda waa jaangooyo muuqaal ah oo go'an, kaas oo aan la bedeli karin mustaqbalka.Sidaa darteed, waxaa la dhihi karaa in aberration chromatic ay sabab u tahay kala duwanaanshaha sawirka iyo sifooyinka jireed ee u dhexeeya LED-yada shakhsi ahaaneed.Ilaa iyo inta LED-yada leh kala duwanaansho yar oo ku filan loo isticmaalo bandhigga, dhibaatada kala duwanaanshaha midabka si buuxda ayaa loo xalin karaa.
Xalka 2. Samee spectroscopy iyo kala soocida midabka (inta badan isticmaal spectroscopy xirfadeed iyo mashiinada kala soocida midabka).Dhaqanku waa la xaqiijiyay.Saamaynta baadhista habkan waa mid aad u wanaagsan.
Midka kore waa dhibaatada aberration chromatic iyo xallinta shaashadda kala-baxa LCD ee ay wadaagaan Rongda Caijing, taas oo aan kaliya si wax ku ool ah u xakameyneynin aberration chromatic.Iyo iyada oo loo marayo kala-soocidda xoogga iftiinka ee isku midka ah (ama hadda).Buuxi shuruudaha joogteynta dhalaalka.
