• Kusurwar Kallo:Sanya nuni yana la'akari da faɗin kusurwar kallonsa don haɓaka amfani ga mai amfani na ƙarshe.

8. Kwatancen Fasaha

Idan aka kwatanta da tsofaffin fasahohi kamar LED na jan GaAsP, AlInGaP da aka yi amfani da shi a cikin LTP-4823KF yana ba da ingantaccen inganci mai haske sosai, yana haifar da haske mafi girma don igiyar turawa iri ɗaya. Idan aka kwatanta da nunin lamba ɗaya, wannan naúrar mai lambobi biyu tana adana sararin allo kuma tana sauƙaƙa taro. Idan aka kwatanta da nunin matrix ɗin ɗigo, raka'a 16 suna ba da hanyar haɗin turawa mafi sauƙi (ƙarfe 20 vs. ƙari don matrix) amma an iyakance su ga haruffa da lambobi da wasu alamomi, ba cikakkun zane-zane ba.

9. Tambayoyin da ake yawan yi (Bisa ga Sigogi na Fasaha)

Q: Menene manufar ƙarfen \"Babu Haɗin\" (Ƙarfe 14)?

A: Wannan ƙarfen yana nan a injiniyance amma ba a haɗa shi da wani abu na ciki ba ta hanyar lantarki. Sau da yawa ana haɗa shi don kwanciyar hankali na injiniyance yayin solder ko don kiyaye daidaitaccen sawun ƙarfe a cikin dangin na'urori masu kama da juna.

Q: Ta yaya zan fassara \"Matsakaicin Daidaitawar Ƙarfin Hasken\" na 2:1?

A: Wannan ƙayyadaddun bayani ne na daidaito. Yana nufin cewa a ƙarƙashin yanayi iri ɗaya na turawa, auna ƙarfin hasken kowane sashe ɗaya bai kamata ya fi sau biyu ƙarfin kowane sashe a kan nuni ɗaya ba. Wannan yana tabbatar da kamanni iri ɗaya a duk sassan da aka haskaka.

Q: Zan iya turawa wannan nuni tare da samar da wutar lantarki 5V?

A: Ee, amma dole ne ka yi amfani da resistor mai iyakancewar igiyar ruwa. Tare da Vf na yau da kullun na 2.6V a 20mA, ƙimar resistor da ake buƙata zata zama R = (5V - 2.6V) / 0.02A = 120 Ohms. Koyaushe tabbatar da ainihin Vf daga takamaiman rukunin ku kuma daidaita ƙimar resistor daidai don cimma igiyar da ake so.

10. Yanayin Amfani na Aiki

Yanayi: Ƙirar Ƙirar Ƙirar Lokaci na Dijital Mai Sauƙi.LTP-4823KF yana da kyau don nuna mintuna da dakika (MM:SS). Microcontroller zai sarrafa nuni ta hanyar haɗawa. Tashar I/O ɗaya za ta sarrafa cathode na sassa 18 (ta hanyar transistors ko IC mai turawa), kuma wasu ƙarfe I/O guda biyu za su sarrafa anode gama gari biyu. Firmware zai sabunta bayanan sashe kuma ya canza tsakanin lambobi biyu da sauri. Babban haske yana tabbatar da cewa ana iya ganin lokaci a cikin ɗaki mai haske, kuma ƙarancin amfani da wutar lantarki yana da fa'ida idan na'urar tana aiki da baturi.

11. Ka'idar Aiki

Na'urar tana aiki akan ka'idar electroluminescence a cikin haɗin p-n na semiconductor. Lokacin da aka sanya ƙarfin wutar gaba wanda ya wuce ƙarfin wutar kunna na diode a kan anode da cathode na sashen LED, electrons da ramuka suna sake haɗuwa a cikin yanki mai aiki (AlInGaP Layer). Wannan sake haɗuwa yana sakin makamashi a cikin nau'in photons (haske). Takamaiman abun da ke cikin gawa na AlInGaP yana ƙayyade ƙarfin bandgap, wanda kuma ke ƙayyade tsawon zango (launi) na hasken da aka fitar, a wannan yanayin, rawaya-orange. Kowane sashe na 16 shine LED ɗaya ko haɗin LED, kuma ta hanyar haskaka waɗannan sassan da zaɓi, ana iya samar da haruffa da lambobi.

12. Trends na Fasaha

Yayin da nunin sassa 16 kamar LTP-4823KF suka kasance masu dacewa ga takamaiman aikace-aikace, babban yanayin a cikin nuni na bayanai yana zuwa ga haɗin kai mafi girma da sassauci. Nunin OLED da LCD na matrix ɗin ɗigo suna zama masu gasa da farashi kuma suna ba da cikakken iyawar haruffa da zane-zane. Duk da haka, nunin sassan LED suna riƙe da fa'idodi a cikin matsanancin yanayi (faɗin yanayin zafi, haske mai girma) da kuma aikace-aikacen da sauƙi, aminci, da dogon rayuwa suka fi mahimmanci. Fasahar AlInGaP ta asali tana ci gaba da samun haɓaka inganci da rayuwa. Bugu da ƙari, akwai ci gaba da ƙoƙarin masana'antu zuwa maƙasudin ƙarancin amfani da wutar lantarki da kuma bin ka'idojin muhalli kamar RoHS, wanda wannan na'urar ta riga ta cika tare da kunshinta mara gubar.
