Qhov txawv ntawm LCD thiab saib yog dab tsi?

1, Qhov txawv ntawm Cov Lus Txhais
LCD (Liquid Crystal Display): LCD yog ib qho kev siv tshuab uas siv cov khoom siv kho qhov muag ntawm cov kua siv lead ua kua molecules los tso saib cov duab. Cov kua siv lead ua kua yog ib yam khoom nruab nrab ntawm cov khoom thiab cov kua hauv lub xeev, uas tuaj yeem hloov nws cov khoom kho qhov muag nyob rau hauv qhov kev txiav txim ntawm qhov hluav taws xob, yog li hloov lub teeb thiab tsim cov duab. LCD thev naus laus zis tau siv dav hauv ntau yam khoom siv, xws li xov tooj ntawm tes, ntsiav tshuaj, TV, khoos phis tawj saib, thiab lwm yam.
Zaub: Cov zaub yog ib lub tswv yim dav dav uas hais txog lub cuab yeej uas tuaj yeem tau txais thiab tso tawm cov teeb liab hluav taws xob (xws li cov teeb liab video, cov teeb liab hauv computer, thiab lwm yam). Lub monitor hloov cov teeb liab tau txais hluav taws xob mus rau hauv cov duab pom lossis cov yeeb yaj kiab los ntawm cov circuits sab hauv rau cov neeg siv saib. Cov zaub tuaj yeem ua raws li ntau yam khoom siv thev naus laus zis, suav nrog tab sis tsis txwv rau LCD, OLED (organic light emitting diode), LED (light emitting diode), CRT (cathode ray tube), thiab lwm yam.
2, Qhov sib txawv ntawm kev ua haujlwm
Kev ua haujlwm ntawm LCD yog qhov tseem ceeb hauv nws lub luag haujlwm tseem ceeb raws li kev siv thev naus laus zis. LCD modulates lub teeb thiab tsim cov duab los ntawm kev tswj cov kev teeb tsa thiab kev sib hloov ntawm cov kua siv lead ua kua molecules. Thaum lub sij hawm tus txheej txheem no, lub LCD yuav tsum tau ua hauj lwm ua ke nrog rau lwm yam hluav taws xob Cheebtsam xws li backlight modules, tsav circuits, thiab lwm yam los hloov hluav taws xob teeb liab mus rau hauv cov duab pom.
Cov haujlwm ntawm tus saib xyuas yog qhov nyuaj dua thiab muaj ntau yam. Ntxiv nrog rau cov duab yooj yim tso saib ua haujlwm, cov lus qhia kuj yuav tsum muaj peev xwm tau txais cov teeb liab hluav taws xob, ua cov ntaub ntawv duab, kho cov duab tsis zoo (xws li ci ntsa iab, qhov sib piv, xim, thiab lwm yam), thiab muab cov neeg siv kev sib cuam tshuam. Tsis tas li ntawd, nrog rau kev tsim cov thev naus laus zis, cov khoom siv niaj hnub no kuj tau tsim cov khoom siv ntse thiab cov neeg siv khoom zoo, xws li kev ua haujlwm kov, lub suab tswj, kev sib txuas lus ntse, thiab lwm yam.
3, Qhov sib txawv ntawm hom
Cov hom LCDs feem ntau suav nrog TN (twisted nematic), IPS (planar hloov dua siab tshiab), VA ( ntsug alignment) thiab lwm yam. Cov hom no muaj qhov sib txawv ntawm cov kua siv lead ua kua molecules, saib cov yam ntxwv ntawm lub kaum ntse ntse, xim qhia, thiab lwm yam, thiab tsim nyog rau cov xwm txheej sib txawv thiab cov kev xav tau.
Hom kev nthuav qhia muaj ntau haiv neeg. Raws li kev siv thev naus laus zis sib txawv, lawv tuaj yeem muab faib ua cov duab LCD, OLED cov lus, LED zaub, thiab lwm yam; Raws li cov hom phiaj sib txawv, nws tuaj yeem muab faib ua ntau hom xws li khoos phis tawj saib, TV saib, tsheb saib, saib xyuas kev kho mob, thiab lwm yam. Txhua hom zaub muaj nws cov yam ntxwv tshwj xeeb thiab daim ntawv thov scenarios.
4, Sib txawv ntawm daim ntawv thov teb
Daim ntawv thov ntawm LCD: Vim nws cov thev naus laus zis paub tab thiab siv ntau lub hauv paus, LCD tau yuav luag nkag mus rau txhua yam ntawm peb lub neej. Los ntawm cov khoom siv portable xws li smartphones thiab ntsiav tshuaj mus rau cov khoom siv loj xws li TV thiab computer saib, LCDs ua lub luag haujlwm tseem ceeb. Tsis tas li ntawd, LCD yog dav siv hauv kev lag luam tswj, khoom siv kho mob, aerospace thiab lwm yam kev lag luam.
Daim ntawv thov ntawm cov lus qhia yog dav thiab ntau yam. Ntxiv nrog rau ntau yam khoom siv tau hais los saum toj no, cov lus qhia kuj tau siv dav hauv ntau qhov chaw xws li kev tshaj tawm xov xwm, digital signage, kev kawm thiab kev cob qhia, kev lom zem ua si, thiab lwm yam. Hauv cov haujlwm no, cov lus qhia tsis yog tsuas yog ua lub luag haujlwm ntawm cov ntaub ntawv qhia, tab sis tseem ua haujlwm tseem ceeb xws li kev cuam tshuam nrog cov neeg siv thiab muab cov kev paub dhau los.
