Ubushushu obuphantsi be-Poly-silicon itekhnoloji ye-LTPS(i-Low Temperature poly-Silicon) yaqala yaphuhliswa ziinkampani zobuchwepheshe zaseJapan naseMntla Melika ukuze kuncitshiswe ukusetyenziswa kwamandla kumboniso we-Note-PC kwaye yenze iNqaku-PC ibonakale ibhityile kwaye ikhaphukhaphu. Phakathi kwiminyaka yoo-1990, obu buchwephesha baqala ukufakwa kwisigaba solingo.LTPS ethatyathwe kwisizukulwana esitsha sephaneli ye-organic-emitting panel i-OLED nayo yasetyenziswa ngokusesikweni ngo-1998, iingenelo zayo ezinkulu zi-ultra-thin, ubunzima obulula, amandla aphantsi. ukusetyenziswa, kunokubonelela ngemibala emihle ngakumbi kunye nemifanekiso ecacileyo.
Ipolysilicon yobushushu obuphantsi
TFT LCDinokwahlulwa ibe yisilicon ye-polycrystalline (i-Poly-Si TFT) kunye nesilicon ye-amorphous (a-Si TFT), umahluko phakathi kwezi zibini zilele kwiimpawu ezahlukeneyo ze-transistor. Ukushukuma kwe-electron kukuphinda-phindwe ngama-200-300 kunoko kwesilicon e-amorphous. Ngokuqhelekileyo eyaziwa ngokubaTFT-LCDibhekisa kwisilicon amorphous, ubuchwephesha obuvuthiweyo, kwiimveliso ze-LCD eziphambili.Ipolysilicon ibandakanya ikakhulu iindidi ezimbini zeemveliso: ubushushu obuphezulu bepolysilicon (HTPS) kunye nepolysilicon yobushushu obuphantsi (LTPS).
Ubushushu obuphantsi bePoly-silicon; Ubushushu obuphantsi bepoly-Silicon; LTPS (ifilimu encinci ye-transistor liquid crystal display) isebenzisa i-excimer laser njengomthombo wobushushu kwinkqubo yokupakisha. iveliswe kwaye iveliswe kwisiseko seglasi yesakhiwo sesilicon eamorphous.Emva kweglasi engaphantsi kwesakhiwo sesilicon eamorphous ifunxa amandla e-excimer laser, iguqulwe ibe yi-polysilicon structure.Ngenxa yokuba yonke inkqubo igqityiwe kwi-600 ℃, ngoko ke i-substrate yeglasi ngokubanzi ingasetyenziswa.
Ci-haracteristic
I-LTPS-TFT LCD ineenzuzo zesisombululo esiphezulu, isantya sokuphendula ngokukhawuleza, ukukhanya okuphezulu, izinga lokuvula eliphezulu, njl.LTPS-TFT LCDilungelelene kune-a-Si, ukuhamba kwe-electron kungaphezulu kwamaxesha e-100 ngaphezulu, kwaye i-peripheral drive circuit inokwenziwa kwi-substrate yeglasi ngaxeshanye. Ukufezekisa injongo yokudibanisa inkqubo, gcina indawo kwaye uqhube iindleko ze-IC.
Kwangaxeshanye, kuba umqhubi wesekethe ye-IC iveliswa ngokuthe ngqo kwiphaneli, inokunciphisa unxibelelwano lwangaphandle lwecandelo, ukwandisa ukuthembeka, ukugcinwa lula, ukunciphisa ixesha lenkqubo yendibano kunye nokunciphisa iimpawu ze-EMI, kwaye emva koko ukunciphisa uyilo lwenkqubo yesicelo. ixesha kunye nokwandisa inkululeko yoyilo.
I-LTPS-TFT LCD yeyona teknoloji iphezulu yokufezekisa iNkqubo kwiPaneli, isizukulwana sokuqala seLTPS-TFT LCDusebenzisa isekethe yomqhubi eyakhelweyo kunye ne-high-performance picture transistor ukufikelela kwisisombululo esiphezulu kunye nesiphumo sokukhanya okuphezulu, yenze i-LTPS-TFT LCD kunye ne-A-Si inomahluko omkhulu.
Isizukulwana sesibini se-LTPS-TFT LCD ngenkqubela phambili yetekhnoloji yesekethe, ukusuka kwi-analog interface ukuya kujongano lwedijithali, ukunciphisa ukusetyenziswa kwamandla.I-on-carrier mobility yesi sizukulwanaLTPS-TFT LCDngama-100 amaxesha e-a-Si TFT, kwaye ububanzi bomgca wepateni ye-electrode imalunga ne-4μm, engasetyenziswanga ngokupheleleyo kwi-LTPS-TFT LCD.
I-LTPS-TFT LCDs idityaniswe ngcono kwi-peripheral LSI kune-Generation 2. Injongo ye-LTPS-TFT LCDS kuku-
I-1) ayinazo iinxalenye zeperipheral ukwenza imodyuli ibe mncinci kwaye ibe khaphukhaphu, kwaye inciphise inani lamalungu kunye nexesha lendibano; (2) Ukusetyenzwa kophawu olulula kunokunciphisa ukusetyenziswa kwamandla; (3) Ukuxhotyiswa ngememori kunokunciphisa ukusetyenziswa kwamandla kubuncinci.
I-LTPS-TFT LCD kulindeleke ukuba ibe luhlobo olutsha lokubonisa ngenxa yeenzuzo zayo zesisombululo esiphezulu, ukugcwala kombala okuphezulu kunye neendleko eziphantsi.Ngezinto eziluncedo zokudityaniswa kwesekethe ephezulu kunye neendleko eziphantsi, inenzuzo ngokupheleleyo ekusetyenzisweni kwezinto ezincinci kunye nezincinci. iiphaneli ezibonisa ubungakanani obuphakathi.
Nangona kunjalo, kukho iingxaki ezimbini kwi-p-Si TFT.Eyokuqala, ukucinywa kwangoku (okt ukuvuza kwangoku) kwe-TFT kukhulu (Ioff=nuVdW/L);Okwesibini, kunzima ukulungiselela ukushukumiseka okuphezulu kwe-p-Si imathiriyeli kwi. indawo enkulu kubushushu obuphantsi, kwaye kukho ubunzima obuthile kwinkqubo.
Sisizukulwana esitsha sobuchwepheshe obuvelaTFT LCD. Izikrini ze-LTPS zenziwe ngokongeza inkqubo ye-laser kwiipaneli ze-amorphous amorphous (A-Si) TFT-LCD, ukunciphisa inani lamacandelo ngama-40 ekhulwini kunye neengxenye ezidibanisayo ngama-95 ekhulwini, ukunciphisa kakhulu amathuba okusilela kwemveliso. ukuphuculwa kokusetyenziswa kwamandla kunye nokuqina, kunye ne-170 degrees ye-angles yokujonga ethe tye kunye nethe nkqo, i-12ms yexesha lokuphendula, i-500 nits Ukuqaqamba, kunye 500:1 umlinganiselo umahluko.
Kukho iindlela ezintathu eziphambili zokudibanisa ubushushu obuphantsi abaqhubi be-p-Si:
Eyokuqala yimowudi yokudibanisa ye-hybrid yokuskena kunye nokutshintsha kwedatha, oko kukuthi, isekethe yomgca idityaniswe kunye, irejista yokutshintsha kunye neshift idityaniswe kwisekethe yomgca, kwaye umqhubi weedilesi ezininzi kunye neamplifier ziqhagamshelwe ngaphandle kumboniso wephaneli ecaba. kunye nesiphaluka esizuzwe njengelifa;
Okwesibini, yonke isiphaluka sokuqhuba ihlanganiswe ngokupheleleyo kwisiboniso;
Okwesithathu, iisekethe zokuqhuba kunye nokulawula ziyadityaniswa kwiscreen sokubonisa.
