Ngophuhliso olukhawulezileyo lweIsikrini se-LEDIshishini, imiboniso ye-LED nayo iyaqhutywa ngabantu. Njenge-novice, ungahlula njani umgangatho weencwadi ze-LED?
Ukuqaqamba
Ukukhanya yeyona nto ibaluleke kakhulu yeIzikrini zokubonisa ezi-LED. Ukuqaqamba okuphezulu, icace gca eboniswe kwiscreen sombongo. Kwisisombululo esifanayo, ukuqaqamba okuqaqambileyo, kokukhona umzobo oboniswe kwisikrini somboniso.
Ukukhanya kwezikrini zokubonisa i-LED kudla ngokulinganiswa kwezi zikhombisi zilandelayo:
Kwiindawo zangaphakathi, kufuneka ifike kwi-800 cd / ㎡ okanye ngaphezulu;
Kwindawo engaphandle, kufuneka ifikelele kwi-4000 cd / ㎡ okanye ngaphezulu;
Phantsi kweemeko zemozulu ezahlukeneyo, isikrini somboniso we-LED kufuneka siqinisekise ukuqaqamba okwaneleyo kwaye sikwazi ukusebenza ngokuqhubekayo iiyure ezingaphezu kwe-10;
Ukungabikho komoya, isikrini se-LED asifanele sibonise ukukhanya okungalinganiyo.
Umbala
Imibala yezikrini ze-LED iquka ikakhulu: ubungakanani bebala, inqanaba le-graycale, ubungakanani bengcakalo, njl. Inqanaba le-greyccale lelinye lezalathiso ezibalulekileyo ezichaphazela umgangatho wezikrini zokubonisa ezi-LED. Imele ukuqaqamba nobumnyama obuqulethwe ngombala. Ngaphezulu inqanaba le-greyscale, ucombule umbala, kwaye uya kuziva ucace gca xa ujongwa. Ngokubanzi, isikrini sokubonisa esidleleni sibonisa inqanaba le-Deadscale le-16, elinokusetyenziselwa ukufumanisa ukuba ingaba umgangatho wezinto eziboniswayo ze-LED ugqwesile.
I-Lifouncrity
Ukuqaqamba kokuqaqamba kwezikrini ze-LED kubhekiselelwe ekubeni ingaba i-shiby yosasazo phakathi kweeyunithi ezikufuphi ifanayo ngexesha lokubonisa umbala.
Ukuqaqamba okuphezulu kwezikrini zokubonisa i-LED kugwetywa ngokubanzi, kubhekiswa kwixabiso lokukhanya kwicandelo lemibala elifanayo ngexesha lokubonisa umbala ngamnye ngexesha lokubonisa umbala opheleleyo. Iiyunithi ezinamachaphaza okanye ezingalunganga zingenambonakalo zihlala zibizwa ngokuba "ngamabala amamnyama". Isoftware ekhethekileyo inokusetyenziselwa ukulinganisa amaxabiso okukhanya phakathi kweeyunithi ezahlukeneyo. Ngokubanzi, ukuba umahluko omkhulu phakathi kweeyunithi ungaphezulu kwe-10%, ithathwa njengendawo emnyama.
Ngenxa yokuba izikrini zokubonisa ezikhokelwa ziqulunqwe ngamacandelo amaninzi, ukuqaqamba kwabo ukuqaqamba kuchaphazeleka ikakhulu kukusasazeka okungalinganiyo phakathi kweeyunithi. Ke ngoko, ingqalelo eyodwa kufuneka ihlawulwe kulo mbandela xa ukhetha.
Ukujonga i-angle
I-Angle ebonakalayo ibhekisa kwi-angle ephezulu apho unokubona khona umxholo wonke wesikrini ovela kumacala omabini esikrini. Ubungakanani be-engile yokujonga ngokuthe ngqo kumisela abaphulaphuli besikrini esibonisa, ukuze sibe ngcono. I-angle ebonakalayo kufuneka ingaphezulu kwe-150 degrees. Ubungakanani be-engile yokujonga bugqityiwe yindlela yokupakisha ityhubhu.
Ukuveliswa kombala
Ukuzala kwakhona kubhekisa kulwahluka kombala wezikrini ze-LED kunye notshintsho ekuqaqambekeni. Umzekelo, izikrini zokubonisa ezikhokelweyo zibonisa ukukhanya okuphezulu kwindawo emnyama kunye nokukhanya okuphantsi kwiindawo eziqaqambileyo. Oku kufuna ukuba umbala wokuzala wenze umbala oboniswe kwizikrini zokubonisa ezi-LED kufutshane nombala kwindawo yokwenyani, ukuze kuqinisekiswe ukuveliswa kombala kwindawo yokwenyani.
Oku kungasentla ngamanyathelo okhuseleko ekufuneka siluthathe xa ukhetha izikrini zokubonisa ezi-LED. Njengomthombo we-LED ye-LED, siqinisekile kwaye sikwazi ukubonelela ngezikrini ezibonisa umgangatho ophakathi. Ke, ukuba unazo naziphi na iimfuno zokuthenga, nceda uqhagamshelane nathi ngokuthe ngqo kwaye siya kukuphendula ngokukhawuleza. Ndijonge phambili ekusebenzeni nani!
