Imwe yemibvunzo inowanzo bvunzwa nezve LED skrini ndeyekuti ivo vanoda backlight. Kunzwisisa mutsauko uripo pakati pekuratidzira tekinoroji ndiyo kiyi yekupindura mubvunzo uyu, semhando dzakasiyana dzemasikirini, akadai seLED neLCD, anoshanda pamisimboti yakasiyana. Mune ino blog, isu tichaongorora basa rekudzosera kumashure mumaratidziro akasiyana, uye kunyanya kana ma LED skrini achiida.
1. Chii chinonzi Backlighting mune Displays?
Backlighting inoreva sosi yemwenje inoshandiswa kuseri kwepaneru yekuratidzira kuvheneka mufananidzo kana zviri kuratidzwa. Muzviitiko zvakawanda, chiedza ichi chinodiwa kuti chiratidziro chionekwe, sezvo chinopa kupenya kunodiwa kuti mapikseli aratidze mavara nemifananidzo zvakajeka.
Semuenzaniso, muLCD (Liquid Crystal Display) skrini, iwo makristasi emvura pachawo haabudise mwenje. Pane kudaro, vanovimba nemwenje yekumashure (yakajairika fluorescent, asi ikozvino yakajairika LED) kuvhenekera mapikseli kubva kumashure, ichivabvumira kuratidza mufananidzo.
2. Musiyano Wakakosha Pakati pe LED neLCD Screens
Usati wataura kana ma LED skrini anoda backlight, zvakakosha kujekesa mutsauko uripo pakati peLCD ne LED skrini:
LCD Screens: Tekinoroji yeLCD inovimba nemwenje wekudzokera nekuti makristasi emvura anoshandiswa mune izvi zviratidziro haaburitse iwo ega mwenje. Mazuva ano maLCD skrini anowanzo shandisa ma LED backlights, anotungamira kune izwi rekuti "LED-LCD" kana "LED-backlit LCD." Muchiitiko ichi, "LED" inoreva mwenje sosi, kwete tekinoroji yekuratidzira pachayo.
LED Screens (True LED): Muchokwadi maratidziro e LED, pixel yega yega yega yega-emitting diode (LED). Izvi zvinoreva kuti LED yega yega inoburitsa mwenje wayo, uye hapana yakaparadzana backlight inodiwa. Aya marudzi emasikirini anowanzo kuwanikwa mumaratidziro ekunze, mabhodhi edhijitari, uye madziro evhidhiyo eLED.
3. Ko LED Screens Inoda Backlight?
Mhinduro iri nyore haisi-yechokwadi LED skrini haidi backlight. Heino chikonzero:
Self-Illuminating Pixels: Muzviratidziro zve LED, pixel yega yega ine diki diki-emitting diode inoburitsa mwenje zvakananga. Sezvo pixel yega yega inogadzira mwenje wayo, hapana chikonzero chekuwedzera mwenje sosi kuseri kwechidzitiro.
Zvirinani Kusiyanisa uye Deep Deep: Nekuti ma LED skrini haavimbi nebacklight, anopa zvirinani mutsauko ratios uye yakadzika matema. MuLCD inoratidzira ine backlighting, zvinogona kunetsa kuwana vatema vechokwadi sezvo backlight haigone kudzimwa zvachose mune dzimwe nzvimbo. Nema LED skrini, mapikisi ega ega anogona kudzima zvachose, zvichikonzera dema rechokwadi uye rakawedzeredzwa musiyano.
4. Common Applications dze LED Screens
Echokwadi ma LED skrini anowanzo shandiswa mune akasiyana-siyana epamusoro-kuita uye hukuru-hukuru maapplication uko kupenya, musiyano, uye akajeka mavara akakosha:
Outdoor LED Billboards: Mahombe e LED masikirini ekushambadzira uye masaini edhijitari anozivikanwa nekuda kwekupenya kwawo kwakanyanya uye kuoneka, kunyangwe muchiedza chezuva.
Mitambo Yemitambo uye Concerts: Zvidzitiro zve LED zvinoshandiswa zvakanyanya munhandare nenzvimbo dzemakonzati kuratidza zvine simba zvine hunyoro hwemhando yepamusoro uye kuoneka kubva kure.
Indoor LED Masvingo: Izvi zvinowanzoonekwa mumakamuri ekudzora, masitudiyo ekutepfenyura, uye nzvimbo dzekutengesa, ichipa yakakwirira-resolution inoratidza ine yakanakisa musiyano.
5. Pane ma LED Screens Anoshandisa Backlighting?
Nehunyanzvi, zvimwe zvigadzirwa zvakanyorwa se "LED skrini" zvinoshandisa backlighting, asi izvi chaizvoizvo LED-backlit LCD kuratidza. Aya masikirini anoshandisa LCD pani ine LED backlight kumashure kwayo kunatsiridza kupenya uye kushanda nesimba. Nekudaro, aya haasi echokwadi maratidziro e LED.
Mumakona echokwadi e LED, hapana backlight inodikanwa, sezvo madhiri-emitting diode ari iwo sosi yezvose chiedza uye ruvara.
6. Mabhenefiti echokwadi LED Screens
Yechokwadi LED skrini inopa akati wandei mabhenefiti pamusoro pechinyakare backlit tekinoroji:
Kupenya Kwepamusoro: Sezvo pixel yega yega ichiburitsa mwenje wayo, ma LED skrini anogona kuwana yakanyanya kupenya mazinga, achivaita akakodzera kune ese arimukati uye ekunze application.
Yakavandudzwa Musiyano: Nekugona kudzima mapixel ega ega, masikirini eLED anopa zvirinani mutsauko uye matema akadzama, anosimudzira kunaka kwemufananidzo.
Kubudirira Kwesimba: Maonesheni e LED anogona kuve ane simba-akawanda kupfuura anodzosera LCD skrini, sezvo ivo vanongoshandisa simba panodiwa chiedza, pane kuvhenekera skrini yese.
Hupenyu hurefu: Ma LED anowanzo kuve nehupenyu hurefu, kazhinji achipfuura 50,000 kusvika 100,000 maawa, zvinoreva kuti ma LED skrini anogona kugara kwemakore mazhinji nekuderera kudiki mukupenya uye kuita kwemavara.
Mhedziso
Muchidimbu, zviratidziro zvechokwadi zve LED hazvidi backlight. Pixel yega yega mune ye LED skrini inoburitsa mwenje wayo, ichiita kuti chiratidziro chizvivhenekere pachako. Iyi tekinoroji inopa akawanda mabhenefiti, anosanganisira epamusoro musiyano, matema akadzama, uye kupenya kwepamusoro. Nekudaro, zvakakosha kusiyanisa pakati pechokwadi maratidziro e LED uye maLCD-backlit maLCD, sezvo iwo ekupedzisira anoda backlight.
Kana iwe uchitsvaga chiratidziro chine mhando yemifananidzo yakanakisa, hupenyu hurefu, uye kugona kwesimba, yechokwadi LED skrini isarudzo yakanaka-hapana backlight inodiwa!
