Display hpaji ningnan langai hku nna, asan sha mu lu ai LED screen ni gaw, hpaga lam hte seng ai display ni, nta gawgap ai lam ni hta, stage performance ni hte kaga lam ni hta, nau nna ai aten hta grai law hkra jai lang wa sai. Shanhte a madung atsam gaw, n-gun ja ai hkrang shapraw ai lam hte kaja dik ai hkrang shapraw ai lam hpe kayau kaya galaw lu ai atsam hta rai nna, shingdu na ningmu hpe n hkra ai sha, n-gun ja ai sumla (sh) video hpe madun dan lu ai atsam rai nga ai. Hpa majaw nga yang, n-gun ja ai LED screen ni a design npawt tara ni gaw, optical structure, circuit layout, arung arai hpaji, hte hkang zing ai ladat ni hpe jawm galaw ai lam ni lawm ai. Lahta na lam ni gaw, hpaji masa hku galaw sa wa na ladat ni hpe, ningmu amyu myu hku nna, hkrak tup tsun dan da ai.
Optical dan dawng ai hkrang shapraw npawt tara ni
Htoi htoi ai LED screen ni a asan sha re ai lam hpe madung hku nna laklai ai pixel ni hpe lajang da ai hte nhtoi-shapoi ya ai arung arai ni hku nna lu la mai ai. Htunghking LED display ni gaw pixel density grai law ai hte n-htoi htoi ai arung arai ni (epoxy (sh) silicone zawn re ai ni) hte shinggrup da ai majaw, n-htoi htoi ai lam yawng hpe grai n-gun n jaw ai. Maga mi de, asan sha mu lu ai LED screen ni gaw, "hollowed-out" (sh) "spaced-out" ngu ai pixel hkrang hpe jai lang nna, LED ni hpe asan sha mu lu ai substrate ntsa matrix langai mi hta bra ayai nga ai. LED ni a lapran na gap ni gaw nhtoi hpe lai shangun ai majaw, nhtoi yawng hpe grau kaja hkra galaw ya lu ai.Common design options ni gaw:
1. Hka htung n nga ai PCB hkrang shapraw ai lam: Printed circuit board (PCB) gaw nhtoi n htoi ai shara ni hta pat shingdang ai lam hpe shayawm na matu hka htung n rawng ai (sh) gridded layout hpe jai lang ai.
2. Side-Nhtoi hpe shapraw ai LED ni: Side-nhtoi hpe shapraw ai LED chips ni hpe lang nna, shingdu kaw na pat shingdang ai lam hpe shayawm kau lu na matu, nhtoi hpe masat da ai maga de shapraw ai.
3. Nhtoi n htoi ai shara ni hta nhtoi hpe grau shayawm lu na matu, nhtoi hpe n-gun n rawng ai shara ni hta Optical-grade resins (sh) glass substrates ni hpe lang ai.
Ndai hkrang ni hpe grau kaja hkra galaw ai hku nna, dai ni na aten na htoi tu ai LED screen ni gaw, pixel pitch hte material lata ai lam hta hkan nna, 70% kaw nna 95% du hkra htoi tu ai madang hpe lu la mai ai.
Circuit hte Driver Hkrang Hkrang
Hkrang nsam rawng ai LED screen ni a circuit design gaw, n-gun n law ai resolution tsaw ai -display hpe rap ra hkra galaw ra ai. Shi a core circuitry hta laksan hku nna:
1. Modular Driver Circuit: Distributed scanning drive ladat hpe jai lang nna, screen hpe laksan hku nna hkang lu ai LED module law law hku garan nna, langai hte langai hta nhtoi hte nsam hpe n galai shai ai sha, tinang a constant-current driver chip hpe bang da ai.
2. Row/Column Scanning Hpaji: Row scan galaw ai hte column address galaw ai hpe kayau kaya galaw ai shaloi, data shapoi ai line ni hte circuit ni a yak hkak ai lam ni hpe shayawm ya lu ai. Nkau mi gaw, n-gun ja ai LED (AM{4}}LED) hpe jai lang ma ai, dai hta LED pixel langai hpra hta, laksan n-gun n rawng ai n-gun n rawng ai n-gun (TFT) switch hpe bang da ai majaw, grayscale hpe grau hkrak hkra hkang lu ai.
3.Low-voltage power supply: Hkamja lam hpe grau kaja hkra galaw na matu hte katsi ai hpe shapraw kau ra ai lam hpe shayawm na matu, asan sha mu lu ai LED screen ni gaw, n-gun n law ai DC power supply (5V or 12V zawn re ai) hpe lang nna, n-gun jai lang ai lam hpe kaja dik htum galaw ai module ni hku nna jai lang ai.
Dai hta n-ga, flexible printed circuit (FPC) hpaji masa hpe jai lang ai gaw, asan sha mu lu ai LED screen ni hpe, shingdu de shinggrup da ai shara hta jung da ra ai lam ni hpe hkan sa lu shangun nna, shanhte a jai lang ai lam ni hpe grau jat wa shangun ai.
Arung arai hpaji hte katsi ai hpe shapraw kau ai lam hpe grau kaja hkra galaw ai
Transparent LED screen ni a matu ra ai arung arai ni hpe lata ai lam gaw, shanhte a nhtoi hpe shalai ya lu ai atsam, ngang grin ai lam, katsi ai hpe shapraw kau lu ai atsam ni hpe hkrak sha hkra machyi shangun ai. Madung arung arai ni gaw:
1.Nhtoi htoi ai npu: Masha law malawng lang ai arung arai ni hta, nhtoi hpe n-gun ja ai hku shalai ya lu ai hte, jak rung n-gun kaja ai ultra-n-gun n-rawng ai shingnip, polycarbonate (PC), shing nrai, polymethyl methacrylate (PMMA) ni lawm ai.
2.LED chip hpe shinggrup ai ladat: COB (Chip on Board) shing nrai GOB (Glue on Board) shinggrup ai ladat hpe lang nna, LED chip hpe npu kaw hkrak hkrak shinggrup da nna, n-gun rawng ai shinggrup ai layer gaw solder joint ni hpe makawp maga ya nna, hkra machyi ai lam hpe grau kaja hkra galaw ya ai.
3.Heat Dissipation Solution: LED ni gaw bungli galaw ai shaloi katsi ai hpe shapraw ai majaw, asan sha mu lu ai LED screen ni gaw, aten galu-bungli hpe ngang grin hkra galaw na matu, thermal grease, magri backplates, shing nrai, active cooling system (fans (sh) liquid cooling zawn re ai) ni hpe jai lang ai.
Hkang ai ladat hte masat kumla shapoi ai lam
Hkrang shapraw ai LED screen ni a display quality gaw, kaja ai hkang zing ai ladat hta madung nga ai. Shi a madung bungli ni hta:
1.Video galaw ai lam: Video galaw ai wa gaw, shang wa ai signal (HDMI, DP, shing nrai network streaming zawn re ai) hpe LED madun na matu htuk manu ai digital signal de galai shai ya nna, scaling galaw ai, nsam hpe gram lajang ai, n-gun bai jat ai lam ni hpe galaw ya ai.
2.Synchronous Control: Synchronous (sh) n bung ai hku hkang ai ladat ni hpe lang ai. Synchronous control gaw aten galu ai mabyin masa ni (stage performance zawn re ai) ni a matu htuk manu ai, asynchronous control (Wi{4}}Fi (sh) 4G hku nna tsan tsan kaw nna gram lajang ai zawn re ai ni) gaw static (sh) n law ai-frequency gram lajang ai application ni a matu grau htuk manu ai.
3.Refresh Rate hte Grayscale: Hpa majaw nga yang, n-gun ja ai LED screen ni gaw 3840Hz hta jan nna n-gun ja ai n-gun hpe lu la nna, 16 bits (sh) dai hta jan ai grayscale madang ni hpe madi shadaw ya lu ai majaw, flicker-n-gun n rawng ai sumla ni hte shingra tara hku nna nsam galai shai ai lam ni hpe lu la mai ai.
Htawm hpang rawt jat galu kaba wa na matu lam matsun ni
Transparent LED screen ni a hkrang shapraw ai lam gaw matut nna rawt jat wa nga ai, htawm hpang na hpaji masa ni hta ndai lam ni lawm mai ai:
1.Higher transparency: Pixel structure hpe grau kaja hkra galaw ai hku nna, 95% jan de htoi tu ai hpe jat wa lu nna, shinggyim masha ni a shingran hpe n-gun jaw ai glass ni a shingran hpe grau ni htep hkra galaw lu ai.
2.Flexible hte bendable design: Hkrang n bung ai electronics hpaji hpe bang nna, shinggrup mai ai (sh) shinggrup mai ai nsam rawng ai LED display ni hpe galaw shapraw ai.
3.Integrated hkra ai hte hkam sha ai lam ni: Capacitive hkra ai layers (sh) grup yin hkam sha ai lam ni hpe asan sha mu lu ai LED screen ni hta bang da ai gaw, shada da matut mahkai ai lam ni hpe madun dan lu ai.
Tsun ga nga yang, asan sha mu lu ai LED screen ni a hkrang shapraw npawt tara ni gaw, myi man nsam, electronic hpaji, arung arai hpaji, computer hpaji ni hpe hpawng de da ai. Shanhte a madung yaw shada ai lam gaw, dan dawng ai lam hpe n-gun dat nna, -madang tsaw ai hkrang shapraw ai lam hpe lu la na matu re. Matut nna hpaji masa rawt jat wa ai hte maren, asan sha mu lu ai LED screen ni gaw grau law ai ginra ni hta shanhte a laklai ai jai lang manu hpe madun dan na re.
