Ukususela ekuveleni kwetekhnoloji yokubonisa ikristale yolwelo (i-LCD) ngo-1968, itekhnoloji iqhubekile nokukhula nokusasazeka, kwaye iimveliso zesiphelo ziye zangena kuzo zonke iinkalo zemveliso nobomi babantu. Ngophuhliso oluqhubekayo lwetekhnoloji, itekhnoloji ye-OLED iye yavela kancinci kancinci kwicandelo elitsha lokubonisa, kodwa i-LCD iseyitekhnoloji ephambili.
Emva kwamashumi eminyaka yophuhliso, amandla okuvelisa iiphaneli ze-LCD aqhubeka edluliselwa kwilizwe lam, kwaye inani labavelisi beephaneli ze-LCD abakhuphisanayo liye lavela. Okwangoku, ishishini leephaneli zokubonisa liye labuyela kwimeko yesiqhelo kwaye kulindeleke ukuba liqalise umjikelo omtsha wokukhula.
(1) Iitekhnoloji ezintsha kwicandelo lokubonisa ziyachuma, kwaye i-LCD iseseyona ndawo iphambili
Okwangoku, i-LCD kunye ne-OLED zezona ndlela zimbini zobuchwepheshe ezisetyenziswa kakhulu kwicandelo leemiboniso ezintsha. Zombini zineempawu zazo kunye neenzuzo zazo ngokwetekhnoloji kunye nokusetyenziswa, ngoko ke kukho ukhuphiswano kwiimeko ezininzi zezicelo zemiboniso. Ii-diode ze-organic-emitting light (ii-OLED), ezaziwa ngokuba zi-organic electro-laser displays kunye nee-organic light-emitting semiconductors, zinokuguqula ngokuthe ngqo amandla ombane abe ngamandla okukhanya kwiimolekyuli zezinto ze-organic semiconductor. Iiphaneli ezisebenzisa itekhnoloji ye-OLED display azidingi ukusebenzisa iimodyuli ze-backlight. Nangona kunjalo, ngenxa yokunqongophala kobonelelo lwezixhobo eziphambili ze-OLED, ukuxhomekeka ekungenisweni kwezinto eziphambili, isivuno esiphantsi semveliso kunye namaxabiso aphezulu, njl. Ngokwembono yenkqubo yeshishini le-OLED yehlabathi, uphuhliso lwe-OLED lusekwinqanaba lokuqala, kwaye i-LCD isekwindawo ebalaseleyo.
Ngokwedatha yeSihan Consulting, iteknoloji ye-TFT-LCD iya kubalelwa kwi-71% yentsimi entsha yetekhnoloji yokubonisa ngo-2020. I-TFT-LCD isebenzisa uluhlu lwe-transistor kwi-substrate yeglasi yephaneli yekristale yolwelo ukwenza i-pixel nganye ye-LCD ibe neswitshi ye-semiconductor ezimeleyo. I-pixel nganye inokulawula ikristale yolwelo phakathi kwe-substrates ezimbini zeglasi ngokusebenzisa ii-point pulses, oko kukuthi, ulawulo oluzimeleyo, oluchanekileyo noluqhubekayo lwe-pixel nganye "point-to-point" lunokufezekiswa ngokusebenzisa ii-active switches. Uyilo olunjalo lunceda ukuphucula isantya sempendulo yesikrini sekristale yolwelo kwaye lunokulawula i-grayscale ebonisiweyo, ngaloo ndlela luqinisekisa imibala yomfanekiso eyinyani ngakumbi kunye nomgangatho womfanekiso omnandi ngakumbi.
Kwangaxeshanye, iteknoloji ye-LCD ikwaphuhla rhoqo, ibonisa amandla amatsha, kwaye iteknoloji yokubonisa umphezulu ogobileyo ibe yenye yezinto ezintsha eziphuhlileyo kwiteknoloji ye-LCD. Ubunzulu bokubona bentsimi obuyenziwe kukugoba kwesikrini sokubonisa esigobileyo kwenza umgangatho womfanekiso ube ngowokwenene kwaye utyebile, kuphucula ingqiqo yokuntywila okubonakalayo, kufiphalise umda ongqongqo phakathi kwe-virtual kunye neyokwenyani, kunciphisa ukuphambuka komgama phakathi komfanekiso osemacaleni omabini esikrini kunye neliso lomntu, kwaye kufumaneke umfanekiso olungeleleneyo. Ukuphucula intsimi yokujonga. Phakathi kwazo, iteknoloji yemodyuli yomphezulu oguquguqukayo we-LCD iphula indlela emiselweyo yeemodyuli zokubonisa ze-LCD kwitekhnoloji yokuvelisa ngobuninzi, kwaye ifezekisa ukuguqulwa kwasimahla kweemodyuli zomphezulu oguquguqukayo we-LCD kwisikrini somphezulu ogobileyo kunye nomboniso othe ngqo, ovumela abasebenzisi ukuba benze ngokwezifiso zabo ngokweemfuno zabo. Cinezela iqhosha ukutshintsha phakathi kweemilo ezithe tye nezithe tye, kwaye ufezekise imo yesikrini kwiimeko ezahlukeneyo ezifana neofisi, umdlalo, kunye nokuzonwabisa, kwaye uhlangabezane nokusetyenziswa kokuguqulwa kweendawo ezininzi.
(2) Ukudluliselwa ngokukhawuleza kwamandla emveliso yeephaneli ze-LCD ukuya kwilizwekazi laseTshayina
Okwangoku, ishishini leephaneli ze-LCD ligxile kakhulu eJapan, eMzantsi Korea, eTaiwan, nakwilizwekazi laseTshayina. Ilizwekazi laseTshayina liqale kade, kodwa liye lakhula ngokukhawuleza kwiminyaka yakutshanje. Ngo-2005, amandla okuvelisa iiphaneli ze-LCD zaseTshayina ayeyi-3% kuphela yehlabathi liphela, kodwa ngo-2020, amandla okuvelisa iiphaneli ze-LCD zaseTshayina anyuke aya kuma-50%.
Ngexesha lophuhliso lweshishini le-LCD kwilizwe lam, kuye kwavela inani labavelisi beephaneli ze-LCD ezikhuphisanayo, ezifana ne-BOE, i-Shenzhen Tianma, kunye ne-China Star Optoelectronics. Idatha ye-Omdia ibonisa ukuba ngo-2021, i-BOE iya kuba kwindawo yokuqala kwiiphaneli zeTV ze-LCD zehlabathi ngee-62.28 yezigidi zeempahla ezithunyelwayo, ezibalelwa kwi-23.20% yemarike. Ukongeza kuphuhliso olukhawulezileyo lwamashishini kwilizwe lam, phantsi kwemvelaphi yecandelo lemveliso yehlabathi labasebenzi kunye nohlaziyo kunye nokuvulwa kwelizwe lam, iinkampani zangaphandle ezifana ne-Samsung Display yaseMzantsi Korea kunye ne-LG Display nazo zityale imali kwaye zakha iifektri kwilizwe lam, nto leyo eye yaba nefuthe elihle kuphuhliso lweshishini le-LCD kwilizwe lam.
(3) Imakethi yephaneli yokubonisa inyukile kwaye iqalile umjikelo omtsha onyukayo
Ngokwedatha yexabiso lephaneli, emva kuka-Okthobha ka-2022, ukwehla kweephaneli kuye kwehla kakhulu, kwaye amaxabiso ezinye iiphaneli ezinkulu abuyele umva. Ukubuyiselwa kwenyanga nge-2/3/10/13/20 iidola zaseMelika / isiqwenga, amaxabiso ephaneli ayaqhubeka nokunyuka, aqalise kwakhona umjikelo wokunyuka. Ngaphambili, ngenxa yokuhla kwezixhobo ze-elektroniki zabathengi, ukunikezelwa okugqithisileyo kunye nemfuno ecothayo kushishino lweephaneli olubekwe ngaphezulu, amaxabiso ephaneli aqhubekile nokuhla, kwaye abenzi beephaneli nabo banciphise kakhulu imveliso. Emva kwesiqingatha sonyaka sokususwa kwempahla, amaxabiso ephaneli aya kuyeka kancinci ukuwa kwaye azinze ukususela ekupheleni kuka-2022 ukuya ekuqaleni kuka-2023, kwaye uthotho lokubonelela lubuyela kancinci kancinci kumanqanaba aqhelekileyo empahla. Okwangoku, amacala okubonelela kunye nemfuno ngokusisiseko akwinqanaba eliphantsi, kwaye akukho mfuneko yokuhla okukhulu kwamaxabiso ephaneli iyonke, kwaye iphaneli ibonakalise umkhuba wokubuyela umva. Ngokwedatha evela kwi-Omdia, umbutho wophando lobuchwephesha kushishino lweephaneli, emva kokufumana ithuba ngo-2022, ubungakanani bemarike yeephaneli kulindeleke ukuba buzise iminyaka emithandathu elandelelanayo yokukhula, okulindeleke ukuba bunyuke ukusuka kwi-US $ 124.2 yeebhiliyoni ngo-2023 ukuya kwi-US $ 143.9 yeebhiliyoni ngo-2028, ukunyuka kwe-15.9%. Ishishini leephaneli liza kungenisa amanqaku amathathu amakhulu okunyuka: umjikelo wokuhlaziya, ukubonelela kunye nemfuno, kunye nexabiso. Ngo-2023, kulindeleke ukuba kuqale umjikelo omtsha wokukhula. Ukubuyiselwa okulindelekileyo kweshishini leephaneli kukwaqhubele phambili ukwanda kwamandla emveliso yabavelisi beephaneli. Ngokwedatha ye-Huajing Industrial Research Institute, amandla emveliso yeephaneli zokubonisa ze-LCD zaseTshayina aza kuba ziimitha zesikwere ezili-175.99 ezigidi ngo-2020, kwaye kulindeleke ukuba afikelele kwiimitha zesikwere ezingama-286.33 ezigidi ngo-2025, ukunyuka kwe-62.70%.
