1. Chii chinonzi LED, LCD?
LED inomirira Chiedza-Emitting Diode, semiconductor mudziyo wakagadzirwa kubva mumisanganiswa ine zvinhu zvakaita seGallium (Ga), Arsenic (As), Phosphorus (P), uye Nitrogen (N). Kana maerekitironi asanganazve nemakomba, anoburitsa chiedza chinooneka, zvichiita kuti maLED anyatsoshanda pakushandura simba remagetsi kuita simba rechiedza. Ma LED akashandiswa zvakanyanya mukuratidzira uye mwenje.
LCD, kana Liquid Crystal Display, inguva yakafara yedhijitari yekuratidzira tekinoroji. Liquid makristasi pachawo haabudise mwenje uye anoda backlight kuti ivavhenekere, senge bhokisi rekushambadzira.
Zvichitaurwa zviri nyore, LCD uye LED skrini dzinoshandisa maviri akasiyana ekuratidzira tekinoroji. LCD skrini inoumbwa nemakristasi emvura, nepo ma LED skrini anoumbwa nemwenje-emitting diode.
2. Kusiyana pakati pe LED neLCD Display
Musiyano 1: Maitiro Okushandisa
Ma LED ari semiconductor light-emitting diodes. Mabheji e LED akashongedzwa kusvika padanho remicron, nediki yega yega LED bead ichiita sepixel. Iyo skrini yepaneru inoumbwa zvakananga neiyi micron-level LED mabedhi. Kune rimwe divi, iyo LCD skrini ndeyemvura yekristaro kuratidza. Yayo huru yekushandisa musimboti inosanganisira kukurudzira mvura yekristaro mamorekuru ane magetsi ezvino kugadzira madotsi, mitsetse, uye nzvimbo, pamwe chete nebacklight, kugadzira mufananidzo.
Musiyano 2: Kupenya
Kumhanya kwekupindura kwechinhu chimwe chete chekuratidzira kwe LED kunomhanya kakapetwa ka1,000 kupfuura kweLCD. Izvi zvinopa LED inoratidzira yakakosha mukana mukupenya, ichiita kuti ionekwe zvakajeka kunyangwe muchiedza chakajeka. Zvisinei, kupenya kwepamusoro hakusi nguva dzose kunobatsira; nepo kupenya kwepamusoro kuri nani kuti utarise kure, kunogona kupenya zvakanyanya pakuona-pedyo. Zvidzitiro zveLCD zvinoburitsa mwenje nekudzoreredza mwenje, zvichiita kuti kupenya kuve kwakapfava uye kusanetsa pameso, asi kunetsa kuona muchiedza chakajeka. Naizvozvo, kune zviratidziro zviri kure, masikirini e LED anonyanya kukodzera, nepo maLCD skrini ari nani pakuona-pedyo.
Musiyano 3: Ruvara Ratidza
Panyaya yemhando yemhando, maLCD skrini ane mashandiro eruvara ari nani uye akapfuma, akajeka emhando yemifananidzo, kunyanya mukupa greyscale.
Musiyano 4: Kushandisa Simba
Iyo simba rekushandisa reshiyo ye LED kune LCD ingangoita 1:10. Izvi zvinodaro nekuti maLCD anovhura kana kudzima iyo yese backlight layer; Kusiyana neizvi, ma LED anogona kuvhenekera chete mapikseli chaiwo pachiratidziro, achiita kuti awedzere simba-rinoshanda.
Musiyano 5: Kusiyanisa
Kutenda kune kuzvivhenekera kwemhando ye LEDs, ivo vanopa musiyano uri nani uchienzaniswa neLCDs. Kuvapo kwebacklight muLCDs kunoita kuti zviome kuwana dema rechokwadi.
Musiyano 6: Refresh mitengo
Mwero yekuvandudza ye LED skrini yakakwira nekuti inopindura nekukurumidza uye inotamba vhidhiyo zvakanyanya mushe, nepo LCD skrini inogona kudhonza nekuda kwekunonoka kupindura.
Musiyano 7: Kuona makona
Chidzitiro che LED chine hupamhi hwekuona kona, nekuti sosi yemwenje yakawedzera yunifomu, zvisinei nekona ipi, mhando yemufananidzo yakanaka kwazvo, LCD skrini mune yakakura kona, chimiro chemufananidzo chichadzikira.
Musiyano 8: Hupenyu
Hupenyu hwescreen ye LED hwakareba, nekuti madhiodhi ayo anoburitsa chiedza akasimba uye haasi nyore kuchembera, nepo LCD screen backlight system uye liquid crystal zvinhu zvichadzikira zvishoma nezvishoma nekufamba kwenguva.
3. Chii chiri nani, LED kana LCD?
MaLCD anoshandisa inorganic zvinhu, izvo zvinochembera zvishoma nezvishoma uye zvine hupenyu hurefu. Ma LED, kune rumwe rutivi, anoshandisa organic zvinhu, saka hupenyu hwavo hupfupi pane hweLCD skrini.
Naizvozvo, maLCD skrini, anoumbwa nemakristasi emvura, ane hupenyu hurefu asi anodya simba rakawanda nekuda kweiyo-on / yese-kudzima backlight. Masikirini e LED, anoumbwa nemwenje-emitting diode, ane hupenyu hupfupi, asi pixel yega yega imwenje sosi, inoderedza kushandiswa kwesimba panguva yekushandiswa.
Kana iwe uchida zvakadzama leran LED indasitiri ruzivo,taura nesu izvozvikuwana zvakawanda
