Kuwonetsa kwa LED vs LCD: Kusiyana Kwakukulu, Ubwino, ndi Zabwino Ndi Iti?

1. Kodi LED, LCD ndi chiyani?

LED imayimira Light-Emitting Diode, chipangizo cha semiconductor chopangidwa kuchokera kumagulu okhala ndi zinthu monga Gallium (Ga), Arsenic (As), Phosphorus (P), ndi Nitrogen (N). Ma elekitironi akalumikizananso ndi mabowo, amatulutsa kuwala kowoneka bwino, zomwe zimapangitsa kuti ma LED azigwira bwino ntchito potembenuza mphamvu yamagetsi kukhala mphamvu yowunikira. Ma LED akhala akugwiritsidwa ntchito kwambiri powonetsa ndi kuyatsa.

LCD, kapena Liquid Crystal Display, ndi mawu otakataka paukadaulo wowonetsera digito. Makhiristo amadzi pawokha satulutsa kuwala ndipo amafuna chowunikira chakumbuyo kuti chiwawunikire, monga ngati bokosi loyatsira zotsatsa.

Mwachidule, zowonetsera za LCD ndi LED zimagwiritsa ntchito matekinoloje awiri osiyana. Zowonetsera za LCD zimapangidwa ndi makhiristo amadzimadzi, pomwe zowonera za LED zimapangidwa ndi ma diode otulutsa kuwala.

2. Kusiyana Pakati pa LED ndi LCD Display

Kusiyana 1: Njira Yogwirira Ntchito

Ma LED ndi semiconductor kuwala-emitting diode. Mikanda ya LED imasinthidwa kukhala yaying'ono mpaka pamlingo wa micron, ndi mkanda uliwonse wawung'ono wa LED umakhala ngati pixel. Chophimbacho chimapangidwa mwachindunji ndi mikanda iyi ya micron-level LED. Kumbali inayi, chophimba cha LCD kwenikweni ndi chiwonetsero chamadzimadzi. Mfundo yake yayikulu yogwiritsira ntchito imaphatikizapo kulimbikitsa mamolekyu amadzimadzi amadzimadzi okhala ndi magetsi kuti apange madontho, mizere, ndi malo, molumikizana ndi kuwala kwambuyo, kuti apange chithunzi.

Kusiyana 2: Kuwala

Liwiro lamayankhidwe a chinthu chimodzi chowonetsera cha LED ndi liwiro la 1,000 kuposa la LCD. Izi zimapereka mawonedwe a LED kukhala mwayi waukulu pakuwala, kuwapangitsa kuti aziwoneka bwino ngakhale pakuwala kowala. Komabe, kuwala kwapamwamba sikumakhala kopindulitsa nthawi zonse; pamene kuwala kwapamwamba kuli bwino kuti muwonere patali, kumatha kukhala kowoneka bwino kuti muwonere pafupi. Zowonetsera za LCD zimatulutsa kuwala poyang'ana kuwala, kupangitsa kuwalako kukhale kofewa komanso kocheperako m'maso, koma kumakhala kovuta kuwona pakuwala kowala. Chifukwa chake, pazowonetsa zakutali, zowonera za LED ndizoyenera, pomwe zowonera za LCD ndizabwino kuti muwonere pafupi.

Kusiyana 3: Kuwonetsa Kwamitundu

Pankhani ya mtundu wamtundu, zowonetsera za LCD zimakhala ndi mawonekedwe abwinoko amtundu komanso mawonekedwe owoneka bwino, owoneka bwino kwambiri, makamaka pamawonekedwe a grayscale.

Kusiyana 4: Kugwiritsa Ntchito Mphamvu

Kugwiritsa ntchito mphamvu kwa LED ku LCD ndi pafupifupi 1:10. Izi ndichifukwa choti ma LCD amayatsa kapena kutseka gawo lonse la backlight; Mosiyana ndi izi, ma LED amatha kuyatsa ma pixel apadera okha pazenera, kuwapangitsa kukhala opatsa mphamvu.

Kusiyana 5: Kusiyanitsa

Chifukwa cha mawonekedwe odziwunikira okha a ma LED, amapereka kusiyana kwabwinoko poyerekeza ndi ma LCD. Kukhalapo kwa backlight mu LCD kumapangitsa kukhala kovuta kukwaniritsa wakuda weniweni.

Kusiyana 6: Mitengo yotsitsimutsa

Mlingo wotsitsimutsa wa skrini ya LED ndi yayikulu chifukwa imayankha mwachangu komanso imasewera makanema bwino, pomwe skrini ya LCD imatha kukokera chifukwa chakuyankha pang'onopang'ono.

Kusiyana 7: Kuwona ngodya

Chophimba cha LED chili ndi mawonekedwe owoneka bwino, chifukwa gwero la kuwala ndi lofanana kwambiri, ziribe kanthu kuti mbali iti, khalidwe la chithunzi ndi labwino kwambiri, LCD chophimba pamakona aakulu, khalidwe la chithunzi lidzawonongeka.

Kusiyana 8: Moyo wautali

Moyo wa skrini ya LED ndi wautali, chifukwa ma diode ake otulutsa kuwala ndi olimba komanso osavuta kukalamba, pomwe mawonekedwe a LCD screen backlight ndi liquid crystal material adzaonongeka pang'onopang'ono pakapita nthawi.

3. Chabwino n'chiti, LED kapena LCD?

Ma LCD amagwiritsa ntchito zinthu zomwe zimakalamba pang'onopang'ono komanso zimakhala ndi moyo wautali. Ma LED, nawonso, amagwiritsa ntchito zinthu zachilengedwe, kotero kuti moyo wawo ndi waufupi kuposa wa LCD zowonetsera.

Choncho, zowonetsera za LCD, zopangidwa ndi makhiristo amadzimadzi, zimakhala ndi moyo wautali koma zimadya mphamvu zambiri chifukwa cha kuwala kwapambuyo-pa / zonse. Zowonetsera za LED, zopangidwa ndi ma diode otulutsa kuwala, zimakhala ndi moyo waufupi, koma pixel iliyonse ndi gwero lowala, kuchepetsa kugwiritsa ntchito mphamvu panthawi yogwiritsira ntchito.

Ngati mukufuna kudziwa zambiri zamakampani a LED,tiuzeni tsopanokuti ndipeze zambiri
