Lub vijtsam laptop yog tsim ntawm lub hauv paus ntawm cov kua siv lead ua kua, uas yog ib qho tseem ceeb tshaj plaws thiab kim khoom ntawm lub khoos phis tawm. Paub txog cov ntsiab lus tseem ceeb ntawm qhov sib npaug yuav pab tau ob qho tib si thaum xaiv lub laptop thiab thaum kho nws tus kheej.
Txhua cov niaj hnub ua kua siv lead ua yog los ntawm cov khoom siv ua kua pom uas tau tshawb pom xyoo 1888 los ntawm biologist Friedrich Reinitzer. Ib qho ntawm lawv lub zog tseem ceeb tshaj plaws yog qhov muaj peev xwm los npaj cov lwg me me hauv qab ntawm hluav taws xob teb. Kev tsim kho sai ntawm cov khoom siv hluav taws xob hauv xyoo nees nkaum ua ntej coj mus rau qhov tshwm sim ntawm monochrome, thiab tom qab ntawd ua kua xim siv kua xim qhia.
Cov ntsiab lus tseem ceeb ntawm LCD zaub yog cov kua siv lead ua kua, nws cov teeb txawb teeb pom kev zoo, ib txoj kab txuas rau thiab txuas cov hlau txhav. Lub matrix nws tus kheej muaj ob lub electrodes pob tshab, nruab nrab ntawm qhov muaj kua muaju, thiab ob qho kev sib txuam sib txuam polarizing lim. Cov lwg me me ntawm cov kua siv lead ua kua yog pib taw qhia hauv ib qho kev taw qhia, sab nraud hluav taws xob hluav taws xob hloov lawv cov kev taw qhia, uas ua rau nws hloov tau qhov pom ntawm lub vijtsam. Txhawm rau tswj txhua pixel ntawm lub vijtsam ib leeg zuj zus, kab thiab kab ntawv yog siv. Txhawm rau muab cov duab xav tau qhov ci, rov qab siv lub teeb, feem ntau me me cov roj fluorescent teeb lossis LED tau teeb raws li lub teeb ci.
Hauv lub laptop, cov txhooj ntsuas nyob ncaj qha rau hauv qhov chaw tiv thaiv sab nraud ntawm lub vijtsam. Nws yuav tsum tau yug los hauv lub siab tias cov kua siv lead ua kua yog ib qho yooj yim tshaj plaws ntawm lub koos pis tawj, yog li ntawd, nws yuav tsum muaj kev tiv thaiv ntawm kev poob siab thiab lwm yam kev puas tsuaj rau cov tshuab. Yog tias kev ncaj ncees ntawm kev sib luag yog qhov txhaum, nws yuav tau hloov. Raws li txoj cai, txoj haujlwm no tau ua tiav hauv cov chaw pabcuam, tab sis nws tuaj yeem ua ntawm nws tus kheej.
Txhawm rau mus rau qhov sib dhos, koj yuav tsum rhuav lub laptop lub vijtsam, rau qhov no koj yuav tsum xub ua tib zoo txiav nws nrog lub hau ntswj thiab rub tawm cov roj hmab cov roj hmab uas qhov screen so thaum kaw. Muaj screws nyob rau hauv lawv, lawv yuav tsum tau unscrewed. Cov txheej txheem yas sab nraud tuaj yeem muab tshem tawm. Nws tseem ntxiv txuas ntxiv nrog latches, yog li nws txoj kev tshem tawm tuaj yeem txuas nrog los ntawm lub suab rov qab dua.
Tshem tawm cov bezel qhia cov tuag tuav los ntawm ntau tus screws, feem ntau yog ob tug. Lawv kuj yuav tsum tau unscrewed. Tom qab ntawd koj tuaj yeem tshem nws thiab nteg nws ntsej muag ntawm daim ntaub mos muag. Ua tib zoo saib rau cov kab txuas, lawv yuav tsum ua kom zoo ntawm cov txuas txuas. Cov txheej txheem rhuav tshem tau tiav lawm, hauv qab kawg yog tshem tawm. Tam sim no nws tuaj yeem hloov nrog ib qho tshiab thiab rov qab sib sau ua ke rau hauv kev txiav txim rov qab.
Thaum xaiv lub laptop, koj yuav tsum nug txog hom zaub. Tshwj xeeb, matrix LED backlight muaj kev ntseeg tau ntau dua li ib qho raws li cov roj fluorescent teeb. Tsis tas li ntawd, nws yog ntau yam kev khwv nyiaj txiag, uas yuav ua rau lub laptop khiav ntawm roj teeb tau ntev dua.
