LCD a matu polarizer a hkrang hte madung bungli galaw ai lam hpe sawk sagawn ai. Polarizer gaw, liquid crystal display (LCD) a madung raw arung arai langai hku nna, shi a galaw shapraw ai manu hta na 20% - 30% daram lawm ai. Raitim, polarizer a galaw shapraw ai hpaji hpe Japan, Dingda Korea hte kaga mungdan ni hku nna langai hkrai sha galaw ai majaw, polazer hte seng nna shiga nau n nga ai. TN LCD a matu polarizer hpe ga shadawn hku nna la ai shaloi, ndai laika buk gaw LCD polarizer lang ai masha law law hte seng ai manghkang nkau mi hpe shalawm da ai.
Polalizer a hkrang bung sumla
Polarizer gaw multi-layer polymer arung arai ni hte hpawng de da ai optical film langai mi rai nna, dai hta polarized light hpe shapraw ai bungli nga ai. Liquid crystal screen hta shi lang ai shara hte maren, madung hku nna lahkawng hku garan mai ai: patch (cause film ngu nna mung shamying ai) hte n kaja ai (reflection film ngu nna mung shamying ai) ngu ai hpe garan mai ai.
Layer langai hte langai a arung arai hte madung bungli ni
Polarizing layer: PVA (polyvinyl alcohol) sumla hkrung hte galaw da ai rai nna, dai gaw polarizing film a madung daw rai nga ai, polarizing film ngu nna mung shamying ai. Polarizing layer gaw polarizer a polarizing galaw ai lam hte shalai ya ai lam hpe dawdan ya ai, dai gaw polazer a nsen hte optical condition hpe hkra machyi shangun ai madung daw mung rai nga ai. Dyeing ladat hku yu yang, polarizing layer a madung galaw ai hpaji masa hpe lahkawng hku garan mai ai: dye series hte iodine series. Hkrang shala hpaji hte maren, hka lim ai sumla hte hka lim ai sumla. Shi a arung arai hte galaw shapraw ai hpaji masa hpe galai shai ai gaw, polarizing degree, shalai ya ai lam, nsen hte myi man n-gun hpe galai shai ai lam hpe chye na la lu na re: PVA film hte galaw ai polarizing layer gaw hka hpe hkap la na matu loi ai, hka lim mat nna polarizing performance hpe sum mat na matu loi ai. Dai majaw, hka hte nbung hpe ginhka nna makawp maga na matu, maga lahkawng maga hta kaja ai myi man bung ai hte asan sha chye na lu ai TAC (cellulose triacate) ngu ai sumla hkrung a layer langai hpe ra sharawng ai. TAC sumla hkrung hpe UV cut hte anti glare functions ni hpe lang nna UV hte anti glare polarzer ni hpe galaw mai ai.
Adhesive: dai hpe myit sumru yu ai sumla hkrung maga de n-gun rawng ai hte n-gun rawng ai sumla hkrung maga de adhesive hku garan mai ai. Reflective film maga de na adhesive a bungli gaw, myit sawn sumru ai sumla hkrung hpe TAC sumla hkrung hte ngang ngang jum da na matu rai nna, dai hpe galaw ra ai lam ni gaw, bai nhtang galaw na ahkang n jaw ai. Adhesive gaw pressure-sensitive adhesive layer langai mi rai nna, polazer a n-gun hte galaw ai lam hpe dawdan ya ai. Adhesive a hkrang shapraw ai lam gaw LCD polalizer lang ai ni a matu ahkyak dik ai manghkang langai mi rai nga ai Separate film: dai gaw dumsu (ethylene terhephthalate) sumla hkrung langai mi rai nna, maga mi de silicon hte ka-up da ai, dai gaw madung hku nna pressure-sensitive adhesive layer hpe makawp maga ya ai. Dai aten hta, shi a hka lim ai n-gun a kaba ai lam gaw, LCD chip a bungli galaw lu ai atsam hpe teng sha hkra machyi shangun ai.
Protective film: PE (polyethylene) sumla hkrung gaw, maga mi de EVA layer (vinyl acetate copolymer) hte ka-up da ai, n-gun n law ai, TAC sumla hkrung a ntsa hpe makawp maga na lit hpe gun hpai nga ai.
Reflective film: PET sumla hkrung langai mi rai nna, maga mi de hka lim mat ai aluminum. Ya aten hta, sumla hkrung law malawng gaw, lam madun ai lam n nga ai. Reflective film hpe semi transparent hte semi reflective film hte galai kau ai rai yang, semi transparent hte semi reflective polarizer hpe galaw mai ai. Dai hta n-ga, ja hte ka da ai, gumhpraw nsam hte laser sumla hkrung amyu myu hpe mung, shingdu nsam amyu myu hte shingran nsam ni hpe hkrang shapraw ai lam amyu myu hpe lu la na matu, myit sumru ai sumla hkrung ni hku nna jai lang mai ai.
Polalizer a madung bungli galaw ai lam hpe madun ai
Table 1 gaw polarizer a bungli galaw ai table langai mi rai nna, lawu na lam ni hpe langai hpang langai tsun dan ai:
.
Optical absorption axis a lam gaw sumla hta madun da ai hte maren rai nga ai. LCD galaw ai wa hpe laksan size hte hkrang bung ai polarizer hpe jaw ai rai yang, optical absorption axis hpe masat da na (sh) tsun dan ra ai.
2. Polarizer a transmitance index hpe langai sha, parallel hte crossed ngu ai daw masum hku garan mai ai. Dai hpe jis-z-8701 hte maren sphere spectrophotometer hpe shinggyin la ai hku nna dawdan chye ai. Dai ni hta, monomer transmissivity ngu ai gaw, polalizer langai a transmissivity hpe tsun mayu ai, parallel transmissivity (H0) ngu ai gaw, polazer lahkawng hpe n-gun jaw ai hpang, transmissivity hpe tsun mayu ai rai nna, shanhte a optical axis gaw parallel rai nga ai, direct cross transmissivity (H90) gaw, polarize lahkawng hpe superposition galaw ngut ai hpang, transmissivity hpe tsun mayu ai. Ndai masat kumla masum hta, H0 hte H90 gaw LCD screen a nhtoi hte shadawn shadang (H0 / H90) hpe hkra machyi shangun ai, dai gaw LCD galaw ai ni a matu grai ahkyak ai, N-gun kaba ai hte n bung ai lam kaba ai a kaja ai hkrang shapraw ai lam hpe lu la na matu, h 0 gaw mai byin ai daram kaji ai hte H 90 gaw mai byin ai daram kaji ai hpe myit mada ga ai.
