Txoj Cai Ua Haujlwm Thiab Hom LCD Backlight Vaj Huam Sib Luag

Backlights yog cov khoom siv kho qhov muag uas muab lub teeb pom kev sab nraub qaum hauv LCD cov khoom lag luam. Txij li cov kua siv lead ua kua iav nws tus kheej tsis muaj lub teeb -emitting zog, lub teeb - emitting qhov chaw, uas yog, ib tug backlight vaj huam sib luag, yuav muab ntxiv tom qab cov kua siv lead ua iav raws li xav tau. Cov ntawv thov suav nrog kev sib txuas lus, kev kho mob, kev zoo nkauj, kev ntsuas, cov cuab yeej siv hauv tsev, cov txhab nyiaj hauv tuam txhab, tsheb - cov khoom siv, cov khoom siv hauv chaw ua haujlwm, cov khoom ua si hluav taws xob thiab cov khoom siv.

Hom Backlights

1. Muaj peb hom backlight panels rau LCD cov ntxaij vab tshaus, uas yog backlight panels siv CCFL teeb, uas yog txias cathode teeb, backlight panels siv EEFL teeb tsis txias cathode teeb, thiab backlight panels siv LED teeb -emitting diodes.

2. CCFL (Cold Cathode Fluorescent Teeb) backlight yog tam sim no tseem ceeb tshaj plaws backlight khoom rau LCD cov ntxaij vab tshaus. Cold Cathode Fluorescent Lamp, uas yog CCFL (Cold Cathode Fluorescent Lamp), lossis CCFT (Cold Cathode Fluorescent Tube). Nws txoj hauv kev ua haujlwm yog tias thaum muaj hluav taws xob siab siv rau ob qho kawg ntawm lub teeb lub raj, ib qho me me ntawm cov hluav taws xob hauv lub teeb lub raj tau ntaus cov electrodes ntawm kev kub ceev los tsim cov hluav taws xob theem nrab thiab pib tawm. Lub teeb ultraviolet generated excites lub phosphor coated rau ntawm phab ntsa sab hauv ntawm lub raj los tsim kom pom lub teeb.

3. LED backlight siv lub teeb -emitting diodes raws li qhov chaw teeb pom kev zoo, uas yog cov cuab yeej zoo tshaj plaws los hloov cov kab mob khaub thuas cathode fluorescent rau yav tom ntej. Lub teeb -emitting diodes yog ua los ntawm ob peb txheej nyias ntawm doped semiconductor khoom. Ib txheej muaj cov khoom siv hluav taws xob ntau dhau, thiab lwm txheej tsis muaj hluav taws xob los ua qhov tsis muaj txiaj ntsig zoo. Thaum ua haujlwm, tam sim no ntws los ntawm, thiab cov hluav taws xob thiab cov voids sib xyaw ua ke, ua rau muaj zog ntau dhau. yog tso tawm nyob rau hauv daim ntawv ntawm optical hluav taws xob. Lub teeb-emitting diodes nrog lub teeb sib txawv-emitting zog tuaj yeem tau los ntawm kev siv cov khoom sib txawv semiconductor.

Backlight vaj huam sib luag cov ntsiab lus

1. LED light backlight: LED light is also called light-emitting diode. Compared with other light sources, the power consumption of a single LED light is very small. From blue to red, LED lights have many colors, commonly used such as "Table 1" and "Table 2"; another special color is white, and "Table 3" gives its commonly used chromaticity range. In various colors, they can be roughly divided into two types: high light and low light: Basically, "Table 1" belongs to low light (although amber, orange and red also have slightly brighter ones), " Table 2" and "Table 3" are highlighted.

Since white is a mixed color and has no identifiable wavelength value, it is represented by its coordinate value on the chromaticity diagram. We customize it as "Cool White" and "Warm White". In all kinds of colors, there is a problem of color deviation, among which blue and white are more obvious, especially white, and now LED suppliers cannot effectively control it.

2. CCFL backlight: Qhov zoo ntawm cov teeb pom kev zoo no yog qhov ci ntsa iab, yog li nws yog qhov pib siv rau hauv cov xim dub thiab dawb tsis zoo, xim xiav hom tsis zoo thiab cov xim kua siv lead ua cov khoom siv nrog thaj tsam loj. Hauv txoj kev xav, nws tuaj yeem ua ntau yam xim raws li cov xim sib txawv ntawm peb lub ntsiab xim. Qhov tsis zoo yog tias lub zog siv hluav taws xob loj, nws yuav tsum tau tsav los ntawm lub tshuab hluav taws xob inverter, thiab kev ua haujlwm kub yog nqaim, uas yog nyob nruab nrab ntawm 0 thiab 60 degrees, thaum lwm lub teeb pom kev zoo xws li LED tuaj yeem ncav cuag ntawm - 20 thiab 70 degrees.

Backlight siv

1. LCD backlight

Lub hauv paus ntsiab lus ntawm LCD backlight yog tias lub reflector, lub teeb qhia phaj, sab sauv thiab qis BEF, LED teeb bar thiab yas ncej hlau ncej yog sib sau ua ke. Thaum lub teeb ci LED tau siv rau, cov khoom siv tawm sab pom lub teeb, uas dhau los ua lub teeb tiaj tus tom qab dhau los ntawm lub teeb qhia phaj, muab cov teeb pom kev zoo rau LCD. qhov chaw.

Thaum lub sijhawm ua haujlwm ntawm lub xov tooj ntawm tes backlight, thaum sib sau ua ke FPC sib dhos ntawm lub teeb qhia phaj, nws yog ib qho tsim nyog los rhuav tshem lub teeb kua nplaum tawm daim ntawv, thiab tom qab ntawd muab FPC sib dhos rau ntawm qhov chaw sib txuas ntawm lub teeb qhia phaj (feem ntau muab. nrog grooves), txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau ruaj khov, thiab feem ntau yuav tsum tau nias ntawm txoj haujlwm nplaum. Yog hais tias lub gripper neeg hlau nyob rau hauv daim duab ua ntej yog siv rau kev ua hauj lwm, tsawg kawg yog ob units yuav tsum tau rau txhua txoj hauj lwm, ib tug ntawm cov uas yog los rhuav tshem lub teeb kua nplaum tawm daim ntawv, thiab lwm yam yog siv rau Grab FPC Cheebtsam.

Lub backlight yog lub hauv paus ntawm lub teeb qab lub iav ntawm lub xov tooj. Tab sis tsis tsuas yog hais txog LED, vim hais tias cov theem tam sim no ntawm lub backlight feem ntau yog tsim los ntawm yas thav duab, reflective zaj duab xis, lub teeb qhia phaj, diffusion, qis lub teeb, lub teeb sab sauv, shading kua nplaum, LED teeb bar.

Vim tias cov khoom siv ua kua siv lead ua kua nws tus kheej yog pob tshab thiab tsis tawm lub teeb, xav tau lub vaj huam sib luag backlight los pab. Qee qhov ntsuas xws li qhov ci thiab qhov tsis sib xws ntawm lub teeb nraub qaum muaj qhov cuam tshuam ncaj qha rau kev ua haujlwm sib txheeb ntawm LCD npo.

Backlight (rov qab teeb) yog qhov ua tau siab -brightness illuminator uas sib txuas cov teeb fluorescent thiab reflectors nyob rau sab nraum qab ntawm LCD thaum lub sij hawm tsim cov LCD. Vim tias cov kua siv lead ua kua ntawm cov kua siv lead ua kua LCD tsis tawm lub teeb, nws tsuas tuaj yeem xa lub teeb, yog li txhawm rau ntxiv lub teeb ci rau sab nraub qaum.

Txawm hais tias qhov kho qhov muag ntawm lub vaj huam sib luag ntawm lub teeb pom kev zoo li yooj yim, cov yam ntxwv kho qhov muag, qhov ntev thiab qhov txheeb ze ntawm txhua qhov khoom tsim muaj kev sib cuam tshuam thiab kev sib raug zoo ntawm kev sib raug zoo rau tag nrho cov kev ua haujlwm kho qhov muag ntawm lub vaj huam sib luag backlight. Nyob rau tib lub sijhawm, yuav ua li cas txhawm rau txhim kho qhov muag pom kev zoo thaum ua kom yooj yim ntawm cov txheej txheem thiab cov txheej txheem yog ib qho tseem ceeb ntawm kev tsim kho lub vaj huam sib luag backlight yav tom ntej.

Lub luag hauj lwm ntawm lub backlight

1. Vim hais tias cov kua siv lead ua kua zaub nws tus kheej yog pob tshab thiab tsis emit lub teeb, yuav tsum muaj ib tug backlight phaj los pab lub teeb emission.

Qee qhov ntsuas xws li qhov ci thiab qhov tsis sib xws ntawm lub teeb nraub qaum muaj qhov cuam tshuam ncaj qha rau kev ua haujlwm sib txheeb ntawm LCD npo.

1. The basic structure of the product: refers to the shape structure, which affects the assembly of the customer's module.

Txij li cov qauv ntawm cov khoom muaj feem xyuam nrog cov neeg siv khoom, nws tsis tuaj yeem hloov pauv ntawm qhov xav tau. Tshwj tsis yog tias cov neeg siv khoom module tseem tsis tau tsim, nws tsuas yog tsim tom qab lub teeb pom kev zoo raug tso tawm.

2. Kev ua tau zoo suav nrog: ci ntsa iab, kev tsis sib xws, qhov kub thiab txias, kev ua haujlwm kub, cov khoom siv tam sim no thiab qhov hluav taws xob thiab lwm yam kev sim thiab cov kev xav tau kho qhov muag.

Cov tswv yim tam sim no thiab qhov hluav taws xob raug txiav txim los ntawm cov qhua tuaj noj mov, yog li nws yuav tsum tau nkag siab meej txog IF thiab Vf qhov tseem ceeb hauv kev tsim kom muaj kev ci ntsa iab.

Brightness yog hais txog kev siv lub teeb ntawm ib chav tsev ntawm lub teeb -emitting cheeb tsam. Qhov kub cia yog li ntawm -30 degree rau ntxiv rau 80 degree; Kev khiav hauj lwm kub ntawm -20 degree rau ntxiv 70 degree.
