LED backlight inoreva kushandiswa kwe LEDs (mwenje emitting diodes) seyakareruka sosi yemvura yekristaro inoratidzwa, nepo LED backlight inoratidzira ingori yekumashure sosi yekristaro yemvura inoratidzwa kubva kune yechinyakare CCFL inotonhora mwenje chubhu (yakafanana nemwenje wefluorescent. ) ku LED (mwenje emitting diode).Iyo yekufungidzira musimboti wekristaro yemvura inogona kungonzwisiswa sechokwadi chekuti magetsi ekunze anoshandiswa kukanganisa iyo mvura yekristaro mamorekuru anovhara kujeka kwechiedza chinoburitswa nebacklight segedhi, uye wozogadzira mwenje pamafirita emavara akasiyana. mavara kuti aumbe mufananidzo.

Edge-lit LED backlight

Iyo yekumucheto-yakavhenekerwa ye LED backlight ndeye kuronga iyo LED inofa padivi peiyo LCD skrini, uye yobva yafananidza mwenje gidhi ndiro, kuitira kuti kana iyo LED backlight module inoburitsa mwenje, mwenje unoburitswa kubva kumucheto kwechidzitiro uendeswe nzvimbo yepakati pechidzitiro kuburikidza nechiedza chegwara ndiro., Kuitira kuti huwandu hwese hwebacklight, huchibvumira iyo LCD skrini kuratidza mifananidzo.

Iko kuvandudzwa kweEdge-lit LED backlight

Nekuenderera mberi kwekuvandudza tekinoroji, iyo yedivi-divi re LED backlight ichakura kubva kune imwechete LED kumusoro uye pasi mativi kusvika kune yekupedzisira single-sided single LED.Kazhinji, imwe LED backlit TV kumativi ose e32 "iyo inogona kuonekwa pamusika inoshandisa ma LED anenge 120 kusvika ku150. Kana chiedza cheTV chikachinjwa kuva LED imwe chete, nhamba ye LED inogona kuderedzwa kusvika 80-100 ( iyo inogona kupedzisira yadzikiswa Huwandu hwema LED hunoenderana neiyo brand tekinoroji) Kana iyo tekinoroji ichifananidzwa, mune ramangwana rinoonekwa, LED imwe chete ichashandurwa kubva kudivi refu (kumusoro kana pasi) kuenda kudivi pfupi (kuruboshwe kana kurudyi. ) Mhando iyi yekuchinja ichashandisa shoma LED Nhamba yezvikamu.

Kuwedzerwa kwehupenyu

Kuderedza kushandiswa kwe LEDs hakusi kungoita zvakanaka pakugadzirisa mari, asi tinoonawo mamwe maitiro akanaka pamamodules.Semuenzaniso, tembiricha yemodule ichadzikiswa nekuda kwekushomeka kwekushandisa maLED.Kana tikatora iri pamusoro 32" LCDTV semuenzaniso, kushandiswa kushoma kwehuwandu hwe LED kunogona kuderedza tembiricha yemodule ne 10% -15%. Kunyangwe isu tisingakwanisi kuverenga nesainzi kuti nhamba iyi inogona kuwedzera hupenyu hwezvikamu zvemagetsi, kana nyangwe maTV, kubva Kazhinji, kudzikisira tembiricha kunofanirwa kuve nemhedzisiro yakanaka pahupenyu hwezvikamu zvemagetsi Rubatsiro urwu rwunonyanya kuoneka munzvimbo yakakura ma LED backlight TV, nekuti kune mashoma ma LED asingawanzo kushandiswa.

Yakafara yekuona kona

Pamusoro pezvo, kushandiswa kwepamusoro-kupenya kupenya kwekusimudzira firimu mhinduro zvakare kunoita basa rakanaka muTV yekuona kona.Nekuti iyo tekinoroji musimboti weiyo yepamusoro-inoshanda kupenya kwekusimudzira firimu ndeyekufambisa mwenje wepolarized kune backlight module kuti itenderere uye kuratidza kusvika yapinda mugirazi.Iyo backlight module inoshandisa kupenya kwekusimudzira firimu inovandudza kupenya ne30% kana ichienzaniswa nemodule isingashandisi firimu remaziso.Sezvo firimu rekusimudzira kupenya kwepamusoro-soro rakasiyana neyakajairwa prism firimu, haidi kupira kona yekutarisa kuti iwedzere kupenya, saka firimu rekusimudzira kupenya rakadai rinofarirwa zvikuru nevagadziri veTV vekune dzimwe nyika nevekunze.Nekuwedzera kuri kuita nzvimbo yeLCDTVs, vatengi vatanga kuve nezvimwe zvinodiwa zvekuona angles.A 47" LCD TV inopfuura 10 000 inches inoiswa pakati peimba yekutandarira. Chokwadi, mukuru wemba anotarisira kuti vaenzi vakagara chero pakona vanogona kunakidzwa nemhando imwe chete yeTV skrini.

Kuchengetedza magetsi uye kuchengetedza simba

Ehe, veruzhinji vanogona kuona zvakananga mabhenefiti e-edge-lit LED backlights, ndiko kudzikiswa kwesimba rose rekushandisa kweTV.Ordinary 32" LED backlight TV, mwero wazvino uno unowanzo kushandisa 80W. Chiyero ichi chakaenzana nechikamu chechitatu mumiyero ichangoburwa yenyika.

Kana vagadziri vachida kuvandudza TV simba rekushandisa zviyero, kune akawanda anowirirana mhinduro, asi kushandisa yepamusoro-inoshanda kupenya kwekusimudzira firimu kunofanirwa kunge iri nzira yakapusa uye yakananga uye inoshanda yekuvandudza mashandisiro esimba.Kana yakabatanidzwa nepamusoro-inoshanda kupenya kwekusimudzira firimu, kushandiswa kwesimba kunogona kuderedzwa ne20% -30% uku uchichengeta mwero wakafanana wekupenya (kuita kwekupedzisira kunoenderana nehunyanzvi hwemhando yega yega).Kubva pakuverenga nhamba, simba rekushandisa reTV rinogona kuvandudzwa kubva pa80W kusvika pa60W kuburikidza nepamusoro-soro bhaisikopo rekusimudzira kupenya.Kuvandudzwa kwekushandiswa kwesimba hakungobvumiri vagadziri kuti vabatane nesimba nemutemo wenyika wekuchengetedza kwezvakatipoteredza, asiwo kunobatsira vatengi vane hukama hwemagetsi mabhiri.

Kubva pane iri pamusoro pehunyanzvi kuongororwa, tinoona kuti kumucheto-lit backlight dhizaini inobatsira zvikuru kune vanogadzira nevatengi.Munguva pfupi iri kutevera, edge-lit single-sided single LEDs inofanirwa kunge iri yekupedzisira kwainoenda kwe LED backlights.
