Ⅰ ụkpụrụ ọrụ nke ihe ngosi LED

Ụkpụrụ ọrụ bụ isi nke ngosipụta LED bụ nyocha siri ike. A na-ekewa nyocha dị omimi na nyocha ahịrị na nyocha kọlụm ụzọ abụọ, ụzọ a na-ejikarị bụ nyocha ahịrị. A na-ekewa nyocha ahịrị n'ime nyocha ahịrị 8 na nyocha ahịrị 16.

Na akara nyocha mode nke ọrụ, onye ọ bụla mpempe LED ntụpọ matrix ibe nwere a set nke kọlụm mbanye sekit, kọlụm mbanye sekit ga-enwe latch ma ọ bụ mgbanwe ndekọ, na-eji igbachi ọdịnaya ga-egosipụta na okwu mode data. Na akara scanning mode nke ọrụ, otu n'ahịrị nke Ikanam ntụpọ-matrix ibe nke otu aha akara akara atụdo na-jikọrọ na yiri on a akara, a ngụkọta nke 8 ahịrị, na n'ikpeazụ jikọọ a akara mbanye sekit; sekit mbanye ahịrị ga-enwerịrị ndekọ latch ma ọ bụ mgbanwe mgbanwe, nke ejiri kpọchie mgbaama nyocha akara ahịrị.

Ikanam ngosi kọlụm mbanye sekit na akara mbanye sekit na-ejikarị microcontroller akara, nke a na-ejikarị microcontroller bụ MCS51 usoro. A na-echekwa ọdịnaya ngosi LED n'ụdị ọnọdụ okwu na ebe nchekwa data mpụga microcontroller, ọnọdụ okwu bụ ọnụọgụ ọnụọgụ abụọ 8-bit.

Ⅱ ihe ọmụma bụ isi nke ihe ngosi Led

3, gịnị bụ modul ngosi LED?

Enwere sekit na nhazi nhazi iji chọpụta, yana ọrụ ngosi, enwere ike imezu site na ọrụ ngosi ngosi dị mfe nke otu isi.

4, Gịnị bụ LED ngosi modul?

Ihe mejupụtara pikselụ ngosi dị iche iche, na-adabereghị na ya, nwere ike mepụta nkeji kacha nta nke ngosi LED. Ụdị 8 * 8, 8 * 7, wdg.

5. Gịnị bụ pikselụ pitch (ntụpọ ntụpọ)?

Ebe etiti dị n'etiti pikselụ abụọ dị n'akụkụ, ka pitch dị ntakịrị, ka anya ahụ dị mkpụmkpụ. A na-akpọkarị ụlọ ọrụ a mkpirisi P iji gosi oghere ebe.

6, Gịnị bụ pixel density?

Amarakwa dị ka njupụta ntụpọ, na-ezokarị aka na ọnụọgụ pikselụ kwa square mita na ngosi.

7, Gịnị bụ nchapụta ọkụ?

Ikanam ngosi unit mpaghara nyere site ìhè ike, unit bụ CD / square mita, nanị tinye bụ a square mita ngosi nyere site ìhè ike;

8, gịnị bụ nchapụta nke ihe ngosi LED?

Ngosipụta ihe ngosi LED na-ezo aka na ọrụ ngosi ngosi nkịtị, mpaghara ihe ngosi nke ọkụ ọkụ, unit ahụ bụ cd / m2 (ya bụ, cd ole nke ọkụ ọkụ kwa square mita nke mpaghara ngosi ahụ.

11, Gịnị bụ ọkwa isi awọ?

Ọkwa isi awọ nke ihe ngosi LED bụ ihe ngosi nke na-egosipụta ọkwa onyonyo nke ngosi. A na-ekewa ọkwa isi awọ nke ihuenyo vidiyo na ọkwa 64, ọkwa 128, ọkwa 256, ọkwa 512, ọkwa 1024, ọkwa 2048, ọkwa 4096 na ihe ndị ọzọ.

12, kedu ihe ngosi nwere agba abụọ, agba pseudo, na agba zuru oke?

Site na agba dị iche iche nke ìhè-emitting diodes nwere ike mejupụtara nke dị iche iche ngosi, dual-agba na-emi esịnede red, green ma ọ bụ odo-acha ndụ akwụkwọ ndụ abụọ na agba, pseudo-agba na-emi esịnede red, odo-acha akwụkwọ ndụ akwụkwọ ndụ, acha anụnụ anụnụ atọ dị iche iche na agba, full -agba mejupụtara uhie, ọcha akwụkwọ ndụ akwụkwọ ndụ, ọcha acha anụnụ anụnụ atọ dị iche iche na agba.

13, gini bu moire?

Ọ bụ na-agbapụ ọrụ nke zuru-agba LED ngosi, LED ngosi ihuenyo a ga-enwe ụfọdụ mgbe ụfọdụ mmiri ripples, ndị a mmiri ripples na physics na-akpọ "moiré".

14, gịnị bụ SMT, gịnị bụ SMD?

SMT bụ teknụzụ dị elu (teknụzụ SURFACE MOUNTED maka mkpụmkpụ), bụ teknụzụ na usoro kachasị ewu ewu ugbu a na ụlọ ọrụ mgbakọ elektrọn; SMD bụ ngwaọrụ etinyere n'elu (ngwaọrụ etinyere n'elu maka mkpụmkpụ).

Ngosipụta LED bụ ụdị mgbasa ozi ngosi ọhụụ ọhụrụ, ọ bụ njikwa nke ngosipụta ngosipụta ọkụ na-emitting diode nke ihuenyo ihuenyo dị larịị, enwere ike iji gosipụta ederede, eserese na ụdị ozi static na animation, vidiyo na ụdị ndị ọzọ. ike ozi, Ikanam electronic ngosi set microelectronics technology, kọmputa technology, ozi nhazi na otu, na-egbuke egbuke na agba, obosara ike nso, elu nchapụta, ogologo ndụ, kwụsiri ike na a pụrụ ịdabere na, wdg Uru, ọtụtụ-eji na azụmahịa mgbasa ozi, omenala arụmọrụ ahịa, ebe egwuregwu, mgbasa ozi, mwepụta akụkọ, ịzụ ahịa nchekwa, wdg, nwere ike gboo mkpa gburugburu ebe dị iche iche. Dị ka isi agba agba nwere ike kewaa n'ime otu agba ngosi na zuru agba ngosi.
