Ubudlelwane phakathi kwe-crystal yekristali kunye neqondo lobushushu 

Amagama aphambili: I-LCD / LCM / TFT / TN / HTN / VND / FNGE, I-STNN, ukujikeleza, ukuhanjiswa kobushushu obunobushushu

Iimveliso zekristale ezingamanzi njenge-LCD, i-LCM kunye ne-TFT zisetyenziswa ngokubanzi kwizixhobo zemizi-mveliso, izixhobo zombane zasekhaya, izixhobo ze-automa kunye nezixhobo zezonyango, ezinemithombo yeendlela zokusebenzisana nomsebenzi kuluntu lwanamhlanje. Iimpawu zeqondo lobushushu sisitshixo sokusebenza kwezixhobo zekristali. Apha ngezantsi siza kucacisa ubudlelwane phakathi kwekristali yekristali kunye nobushushu:
① Ithetha ngokufuthi ukuba imeko ikho kumazwe amathathu: uqinile, ulwelo, kunye negesi. Ikristali yolwelo ithathelwa ingqalelo imeko yesine, njengoko ilele phakathi kolwelo kwaye iqinile, enolungelelwaniso lwemolekyuli eyahlukileyo. Phantsi kweemeko zobushushu ezahlukeneyo, ilungiselelo leemolekyuli zolwelo ezitshintsha kakhulu, ezichaphazela ngokuthe ngqo utshintsho lwe-molecular lwekristale yolwelo, ke ifuthe kwipropathi yayo yokuphuma kwaye ekugqibeleni intsebenzo yokubonisa.
Kumgangatho we-0-50 Umzekelo, kwizikristali ze-nematic amanqindi, iimolekyuli zihambelana ngokucocekileyo kwicala elithile, njengeqela eliqeqeshiweyo lamajoni. Olu lungiselelo lucwangcisiweyo luvumela ukukhanya ukuba kudlule kwi-crystal yolwelo ngakumbi, yenza iipropathi zekristali yolwelo oluzinzileyo kakhulu kolu luhlu lobushushu. Oku kubangela ukuba kwenziwe umsebenzi wokubonisa olona bonakalise lwama-crystal ulwelo.
Njengoko amaqondo obushushu anyuka ngokuthe ngcembe ukuya kwi-50-90 ℃, iimolethi zekristali yolwelo zizuza amandla amaninzi, ezikhokelela ekunyukeni intshukumo ye-thermal. Ilungiselelo lemolekyuli liya kuba lincinci kwaye lingakhathali ngakumbi. Olu tshintsho kulungiselelo lweemolekyuli lubangelwa kukusasazeka ngakumbi kunye nokuvuselelwa kokukhanya ngexesha lokusasazwa kwayo. Umzekelo, ukuba amatye amaninzi aphoswa kwichibi elithobekileyo, indlela ethe tye yenye yokukhanya iphazanyisiwe, ukunciphisa ubukhulu bokukhanya okudlula kwikristali yolwelo, ngaloo ndlela kuncipha ukuhambisa. Ngenxa yoko, umahluko wekristali yolwelo uyancipha, kwaye umgangatho womboniso ulalelwe.
Njengoko amaqondo obushushu eqhubeka enyuka, ogqithileyo kwi-90 ℃, ilungiselelo leemolekyuli zekristali iphantsi kweenguqu ezibaluleke kakhulu xa kufikelelwe kwinqanaba elithile. Ikristali yolwelo inokuguqula ukusuka kwelinye inqanaba ukuya kwenye, isuka kwisigaba solungelelwaniso kwisigaba se-isotropic. Ngeli tshintsho, iipropathi ezibonakalayo zekristali yolwelo zitshintshe ngequbuliso, kwaye ukukhanya okukhanya kutshintsha kakhulu. Umzekelo, xa ezinye izinto ezithile zekristale zifikelela eli qondo lobushushu ibalaselayo, i-crystal yolwelo, eyayingabonakaliyo, ngequbuliso iba lifu, ngokuhla okubukhali. Oku kungenxa yokuba inqanaba lesifo semoyari inyuka kakhulu, senza ukuba kube lula ukuba ukukhanya kudlule ngokutyibilikayo. Okwangoku, umsebenzi wokubonisa ulahlekile, kwaye izinto ezibonakalayo azinakusetyenziselwa ukubonisa.
Iqondo lokushisa eliphantsi: Kwimeko yobushushu obuphantsi, i-viscosity inyuka, icothisa isantya sokujikeleza kweemolekyuli ezingamanzi kunye nokwandisa ixesha lokuphendula, elinokubangela ukuba imifanekiso eguqukayo okanye enokuyifumana imifanekiso eguqukayo. Olu luhlu lwamaqondo amaqondo obushushu luhlangatyezwa rhoqo kubomi bemihla ngemihla, kunye nokuphucula ukusebenza kwesibonisi kolu luhlu lwamaqondo kuhlala kungumceli mngeni obalulekileyo kushishino. I-Dalian Mpuma i-Co. njengenkampani eneminyaka engama-30 yamava oqeqesho, sinesiseko sobugcisa esiqinileyo. Iqondo lethu lokugcina i-ultra lubanzi iqondo / i-TN / htn segiment skristal skristal screenns inokuqinisekisa ukubonisa ngaphandle kwezixhobo zokuncedisa; Izikrini zethu ze-stn / fstn dot ze-Dot zinokuqinisekisa ukubonisa kunye nokuphuculwa kwembuyekezo yeqondo lobushushu.
Xa iqondo lobushushu lingaphantsi kwe-50 ℃, i-viscosity yezinto ezikristali igqitha kwimilinganiselo yombane, kwaye ilungiselelo leemolekyuli lingena ngokujikeleza, kwaye i-crystal yekristali ikwaphulukene nomsebenzi wokubonisa. Okwangoku, akukho kuqhekeka kule ngxaki yezobuchwephesha kwishishini.
Isishwankathelo, ubudlelwane phakathi kwekristali yolwelo kunye neqondo lobushushu yintsimi enobunzima, ebandakanya ukusebenzisana kwezinto, kubandakanya iipropathi zekristali ye-crystal, kunye nemozulu yangaphandle yemodeli. Iqela le-Dalian Mpuma ye-Dalian Bownen.
