Tushen Nuni Led

LED nuni ne lebur panel nuni, hada da mahara kananan LED module bangarori, amfani da su don nuna rubutu, hotuna, video, video sakonni da sauran daban-daban bayanai kayan aiki.

Ana amfani da shi musamman don tallan cikin gida na waje, nuni, wasa, bayanan aiki da sauran dalilai. Wanda aka saba sanyawa a wuraren kasuwanci, facade na gini, gefen titi, wuraren jama'a, matakin cikin gida, dakunan taro, dakunan kallo, wuraren liyafa, wuraren bayar da umarni da sauran wurare, suna taka rawa wajen nunawa.

Ⅰ. ka'idar aiki na LED nuni

Ainihin ka'idar aiki na nunin LED shine dubawa mai ƙarfi. Ana rarraba sikanin daɗaɗɗen zuwa binciken layi da kuma duban shafi hanyoyi biyu, hanyar da aka saba amfani da ita ita ce binciken layi. Ana rarraba sikanin layi zuwa sikanin layi 8 da duban layi 16.

A cikin yanayin duban layi na aiki, kowane yanki na ɗigon matrix LED yana da saiti na da'ira na ginshiƙi, da'irar drive ɗin shafi dole ne ya sami latch ko rajistar motsi, ana amfani da shi don kulle abun ciki don nunawa a cikin bayanan yanayin kalmar. A cikin yanayin aikin sikanin layi, jeri iri ɗaya na LED ɗigo-matrix yanki na madaidaitan fil ɗin sarrafa layin suna ana haɗa su a layi daya akan layi, jimlar layukan 8, kuma a ƙarshe an haɗa su zuwa da'irar tuƙi na layi; Dole ne da'irar tuƙi ta layi ta kasance tana da latch ko rajistar motsi, wanda ake amfani da ita don kulle siginar duba layin.

LED nuni da'irar drive da'irar da line drive da'irar gaba ɗaya ana amfani da microcontroller iko, fiye da amfani microcontroller ne MCS51 jerin. Abubuwan nunin LED gabaɗaya ana adana su ta hanyar yanayin kalma a cikin ƙwaƙwalwar ajiyar bayanan waje na microcontroller, yanayin kalmar lambar binary 8-bit ce.

Wanda ya ƙunshi adadin pixels nuni, mai zaman kansa na tsari, zai iya samar da mafi ƙarancin naúrar nunin LED. Yawanci 8 * 8, 8 * 7, da sauransu.

5. Menene pixel pitch (dot pitch)?

Tsakanin nisa na tsakiya tsakanin pixels biyu maƙwabta, ƙarami mafi ƙaranci, gajeriyar tazarar gani. Yawanci ana taƙaita masana'antar P don nuna tazarar maki.

6, Menene girman pixel?

Hakanan aka sani da yawan dige, yawanci yana nufin adadin pixels a kowace murabba'in mita akan nuni.

7, Menene haske mai haske?

Wurin nunin LED da aka fitar da hasken haske, naúrar CD/mita murabba'in ce, kawai sanya nunin murabba'in murabba'in da hasken haske ya bayar;

8, menene haske na nunin LED?

Hasken nuni na LED yana nufin aiki na al'ada na nuni, yanki na nuni na ƙarfin haske, naúrar tana cd / m2 (watau cd nawa na ƙarfin haske a kowace murabba'in mita na yankin nunin.

11, Menene matakin launin toka?

Matsayin launin toka na nunin LED nuni ne da ke nuna matakin hoton nunin. Matsayin launin toka na allon bidiyo an raba gabaɗaya zuwa matakan 64, matakan 128, matakan 256, matakan 512, matakan 1024, matakan 2048, matakan 4096 da sauransu. Mafi girman matakin launin toka, mafi kyawun matakin hoto, matakin girman launin toka na 256 ko fiye, bambancin hoton ba shi da girma sosai.

12, mene ne kalar-dual, launi-launi, nuni mai cikakken launi?

Ta hanyar launuka daban-daban na diodes masu fitar da haske za a iya haɗa su da nuni daban-daban, launuka biyu sun haɗa da ja, koren ko rawaya-kore launuka biyu, launi mai ƙima ya ƙunshi ja, rawaya-kore, shuɗi launuka daban-daban uku, cikakke. -launi ya hada da ja, koren tsantsa, shudi mai kyau kala uku daban-daban.

13, menene moire?

Yana cikin aikin harbi na nunin LED mai cikakken launi, allon nunin LED za a sami wasu ripples na ruwa marasa daidaituwa, waɗannan ripples na ruwa a kimiyyar lissafi ana kiran su "moiré".

14, menene SMT, menene SMD?

SMT fasaha ce mai ɗorewa (fasaha na SURFACE MOUNTED a takaice), a halin yanzu shine mafi mashahuri fasaha da tsari a cikin masana'antar hada-hadar lantarki; SMD shine na'urar da aka ɗora sama (na'urar da aka ɗora a saman gajarta).

Nunin LED sabon nau'in watsa labarai ne na nunin bayanai, shine ikon sarrafa yanayin nunin haske-emitting diode nunin allo na allo, ana iya amfani da shi don nuna rubutu, zane-zane da sauran nau'ikan bayanai masu mahimmanci da rayarwa, bidiyo da sauran nau'ikan tsauri bayanai, LED lantarki nuni kafa microelectronics fasaha, kwamfuta fasahar, bayanai aiki a daya, tare da haske launuka, m tsauri kewayon, high haske, tsawon rai, barga da kuma abin dogara, da dai sauransu Abvantbuwan amfãni, yadu amfani a kasuwanci kafofin watsa labarai, al'adu yi kasuwar, wuraren wasanni, yada bayanai, sakin labarai, kasuwancin tsaro, da dai sauransu, na iya biyan bukatun yanayi daban-daban. Bisa ga launi tushe launi za a iya raba zuwa launi guda nuni da cikakken launi nuni.
