Dai ni na aten na shiga ni hpe garan gachyan na matu ahkyak ai ladat langai hku nna, shinggan LED display ni hpe galaw shapraw ai lam ni a ngang kang ai hte hpaji masa ni gaw, arung arai kam hpa mai ai lam, madun dan ai atsam, asak hkrung lam hpe hkrak hkra hkra machyi shangun nga ai. Lahta na gaw shinggan LED display ni a matu core galaw shapraw ai ladat ni hpe hkrak tsun dan da ai.
Raw Material hpe lata la nna jep joi ai lam
Shinggan LED display ni hpe galaw shapraw ai lam gaw, -madang tsaw ai arung arai ni hpe lata la ai kaw nna hpang wa ai. Core arung arai ni hta LED pyengdin ni, driver IC ni, PCB ni, shinggrup da ai arung arai ni, power module ni lawm ai. Display unit a core hku nna, LED pyengdin ni gaw nhtoi htoi tu ai, n bung ai lam grai law ai, nbung laru hpe grai kaja hkra hkam sharang lu ai pyengdin ni hpe jaw ra ai. Shanhte gaw hka hte nhpu n shang hkra galaw nna, laksan shinggyin la ai ladat hpe lang ai. Driver IC ni gaw pixel nhtoi hte nsam hpe hkrak hkrak hkang lu nna, shanhte a ngang grin ai lam gaw display a n-gun hpe hkrak hkrak hkra machyi shangun ai. PCB ni gaw, nbung katsi ai hte nbung katsi ai zawn re ai n hkru n kaja ai masa ni hpe hkam sharang lu na matu, nbung n-gun grai ja ai hte n-gun ja ai n-gun hpe hkam sharang lu ai substrate ra nga ai. Dai hta n-ga, raw material yawng hpe n tawn da shi yang, n-gun ja ai bungli galaw ai lam hpe chyam dinglik ai lam hte grup yin hte htuk manu ai lam hpe jep joi ai lam ni hpe galaw ra ai, dai hta, n-gun ja ai-temperature aging tests, humidity tests, hte mechanical strength tests ni lawm ai, dai gaw hpaga lam a madang ni hpe hkan sa lu na matu re.
SMT hpe jung ai hte ginwang hpawng de ai
Raw materials ni hpe lai ngut ai hpang, SMT (surface mount technology) hpe n-gun dat ai lam hpe galaw hpang wa ai. Ndai lahkam hta, PCB ntsa hta driver IC, resistor, capacitor zawn re ai hkrak tup ai arung arai ni hpe hkrak hkrak jung na matu, reflow soldering ladat hku nna ngang ngang jum da na matu, tinang hkrai galaw ai jak ni hpe lang ai. Ndai ladat gaw, katsi ai solder joint ni hte component ni hpe hkra machyi hkra, nbung katsi ai hpe atsawm sha hkang ra ai. Dai hpang, LED ni hpe PCB ntsa hta masat da ai shara ni de, hkrak tup ai die bonders hte wire bonders ni hpe lang nna, wan n-gun matut mahkai lam ni hpe ngut kre hkra galaw ai. Shinggan na madun dan ai lam ni hpe makawp maga ai atsam hpe grau kaja hkra galaw na matu, circuit hpe hpawng de ngut ai hpang, hka n shang hkra galaw ra ai, ga shadawn, conformal coating (moisture-hkum hkrang, hka n htum hkra, hte mildew-hkum hkrang) hte shinggrup nna, circuit board ni hpe corrosion resistances hpe grau kaja hkra galaw ra ai.
Module hpe shinggrup da ai hte hka n shang hkra galaw ai
LED module gaw, LED law law, driver circuit, nbung hpe shapraw kau ya ai hkrang ni lawm ai, display langai a madung madun ai unit rai nga ai. Module hpe shinggyin ai shaloi, module board hte nta hpe hkrak hkrak press-fit ladat hte rau ngang ngang jum da nna, dai hpang laksan potting compound (silicone (sh) epoxy zawn re ai) hpe bang nna, hka hte nhpu n shang hkra, hkum tsup hkra galaw lu ai. Potting compound gaw nhtoi hpe n-gun ja hkra shapraw lu ai atsam nga ai sha n-ga, aten galu-shinggan de lang ngut ai hpang, nsam hpraw ai (sh) n-gun n rawng ai UV- hpe ninghkap lu ai atsam nga ra ai. Dai hta n-ga, module a jut ni hte n-gup magap ni hpe sealing strips (sh) ultrasonic welding hpe lang nna secondary seal galaw ra ai, dai hku nna IP65 (sh) dai hta jan ai makawp maga ai masat masa yawng hpe lu la na matu, marang kaba hte nhprang wan zawn re ai grai sawng ai shinggan makau grup yin ni a ra kadawn ai lam ni hpe hkan sa lu na matu re.
Cabinet hkrang hpe galaw ai hte hkum tsup ai-Screen hpe hpawng de ai
Shinggan LED display ni a cabinet ni hpe aluminum alloy (sh) die-cast aluminum hte galaw da ai majaw, n-gun n law ai hte n-gun kaba ai lahkawng yan hpe jaw ya lu ai. Cabinet galaw ai shaloi, n-gun n rawng ai hte katsi ai hpe shapraw kau lu ai atsam hpe jat ya lu na matu, n-gun n rawng ai CNC jak ni hpe htu ai, htu ai, npu hpe gram lajang ai (anodizing or spray coating zawn re ai) ni hpe galaw ra ai. -screen ting hpe hpawng de ai aten hta, module law law hpe cabinet kata kaw, shara tam ai pin ni hte hpawng de ai ladat ni hpe lang nna, shim lum hkra galaw da ai. Display pixelation (sh) htoi tu ai line ni hpe koi lu na matu, hkrak hkrak gram lajang ai ladat ni gaw, pixel pitch hpe n galai shai hkra galaw ya ai. Cabinet ni hpe hka n shang hkra galaw ai connector ni hte nbungli plug ni hpe lang nna matut da ai majaw, signal hpe grau nna ngang grin ai hte shim lum ai hku htawt sit lu na re.
Burn- hpe chyam dinglik ai hte Quality jep joi ai lam hta
-screen hpe tup hkrak shinggyin ngut ai hpang, dai arai hpe grai sawng ai wan nat-chyam dinglik ai lam hta galaw ra ai. Hkying hkum 72 jan na hkra, nbung katsi ai (50℃-60℃) hte nhtoi htoi ai (full load) hta chyam dinglik ai gaw aten galu-lang ai hpe shingdaw nna, aten garai n du yang hkrat sum mat chye ai screen ni hpe shingdaw ai. Dai hta n-ga, professional optical inspection jak ni hpe lang nna, screen parameters ni rai nga ai, nhtoi htoi ai lam, nsam bung ai lam, n bung ai lam ni hpe shadawn shadang masat da ai hku nna, display gaw design madang ni hte maren rai hkra galaw ai. Hpang jahtum, galaw ngut sai arai hpe hka n shang hkra chyam dinglik ai lam (high-pressure water jets zawn re ai), jak rung n-gun hpe chyam dinglik ai lam, wan n-gun shimlam masat masa ni (CE hte UL zawn re ai) ni hpe galaw nna, kam mai ai lam hpe tup hkrak jep chyoi lu ai.
Hkawm ai hte htaw sa ai
Test yawng hpe awng dang ai LED display ni hpe hpaji rawng ai hku shinggyin la na re. Dai sumpu kata hpe shock-absorbing foam hte shinggrup da nna, shinggan de gaw hka n shang ai hte hka n htum ai hpun (sh) magri sumpu ni hte shinggrup da ai majaw, htaw sa ai shaloi, n-gun n rawng ai hte hka n shang ai hpe hkam sharang lu ai. Hpaji masa hte seng ai laika buk, install galaw na matu matsun laika, warranty laika ni hpe mung, hkrak jai lang nna gram lajang lu na matu bang da ai.
Tsun ga nga yang, shinggan LED display ni a matu galaw shapraw ai lam gaw, electronic engineering, arung arai hpaji, hte hkrak hkrak galaw shapraw ai hpaji ni hpe hpawng de da ai majaw, lahkam shagu hta madang tsaw ra ai. Hkrak ai quality hpe hkang zing ai hte hpaji masa ningnan ni hpe jai lang ai hku nna sha, shinggan na n hkru n kaja ai makau grup yin hpe hkam jan lu ai, sumla quality tsaw ai hte asak galu ai lam lahkawng yan hpe jaw ya lu ai, -quality tsaw ai display ni hpe galaw lu na re.
