LED ni a nsam hte nhtoi htoi ai atsam gaw, dai ni hpe galaw shapraw ai shaloi lang ai arung arai ni hte ladat ni hte seng nga ai. Hpraw, hpraw, hkyeng ni hpe grau nna lang ma ai. Hpa majaw nga yang, LED display ni gaw n-gun n law ai (5V sha) hta bungli galaw ai majaw, voltage (sh) current hte galai shai mai ai nhtoi hpe active hku shapraw lu ai, n-gun n-gun hpe n-hkap la lu ai, n-gun n-gun hpe n-hkap la lu ai, n-gun n-gun n-rawng ai, n-gun n-rawng ai aten galu ai (100,000 hours) hta kaga LED display ni n mai shingjawng lu ai. kaba ai-madun ai arung arai ni.
Hpraw hte hkyeng ai LED ni hpe pixel langai hku nna hpawng de da ai madun ai screen hpe dual-color screen (sh) full-color screen ngu shamying ma ai; hpraw, hpraw, hkyeng ai LED ni hpe pixel langai hku nna hpawng de da ai madun ai screen hpe tri-color screen (sh) full-color screen ngu shamying ma ai. Nta kata na LED screen ni gaw 2-20 mm daram pixel size nga ai, law malawng gaw LED chip law law hpe lang nna, n bung ai primary nsam ni hpe langai sha hta shinggyin tawn da ai. Shinggan LED screen ni hta pixel size gaw 8-32 mm rai nna, pixel langai hpra hta langai hkrai a monochrome LED law law hte hpawng de da ai. Masha law malawng galaw ngut sai arai ni hpe pixel tubes ngu shamying ma ai; dual-color pixel tubes ni hta gaw, madung hku nna, hpraw ai LED 2 hte hpraw ai LED 1 lawm nna, tri-color pixel tube ni hta gaw, hpraw ai LED 1, hpraw ai 1, hpraw ai LED 1 lawm ai.
Monochrome, dual-color, tri-color screen ni hpe galaw na matu LED ni hpe lang ai rai tim, pixel langai hpe hpaw shabawn da ai LED langai hpra a nhtoi hpe sumla langai hpe madun na matu galai shai mai ai. Ndai galai shai ai lam a fineness hpe gaw, madun ai screen a grayscale level ngu shamying ma ai. Grayscale madang grau tsaw wa yang, madun da ai sumla gaw grau n-gun ja wa nna, nsam ni grau sut su wa nna, dai hte maren madun dan ai hkang ai ladat mung grau sawng wa ai. Madung hku nna, 256-level grayscale sumla hta grai hkrak ai nsam galai shai ai lam ni nga ai, 16-level grayscale sumla hta grai dan dawng ai nsam galai shai ai lamu ga jarit ni nga ai. Dai majaw, ya aten na nsam LED screen ni hta 256 kaw nna 4096 du hkra grayscale madang nga ra ai.
Display ni hta lang ai LED luminescent arung arai ni gaw lawu na hkrang ni hku nna pru wa ai:
LED pyengdin (sh) pyengdin langai sha): Madung hku nna nhtoi-hkap la lu ai atsam nga ai epoxy resin shell kata kaw shinggrup da ai LED chip langai, reflector langai, magri anode langai, magri cathode langai hte hpawng de da ai. Langai (sh) law law (n bung ai nsam) single lamp ni gaw basic pixel langai hpe hpaw shabawn lu ai. Shanhte a nhtoi grai htoi tu ai majaw, shinggan kaw na madun dan ai lam ni hta grau lang ma ai.
LED dot matrix modules: Chip law law hte hpaw nna, nhtoi htoi tu ai matrix hpe hpaw shabawn da nna, plastic shingnip kata na epoxy resin shingnip langai mi hta shinggrup da ai. Row hte column scanning drive ni a matu htuk manu ai, -density kaba ai display ni hpe loi loi hte galaw lu ai, law malawng gaw nta kata na display ni hta lang ai.
Surface mount LEDs (sh) SMD LEDs ni gaw, ntsa kaw jung da ai package kata na LED ni rai nna, nta kata na full-color display ni a matu htuk manu ai, langai sha-point hpe gram lajang lu ai hte mosaic hkra machyi ai lam ni hpe atsawm sha dang manga lu ai.
