Nalalka gadaal ee tooska ah ee LED
Marka la isticmaalo nalalka dambe ee LED-ka ee geeska ku shaqeeya ee LCD-yada dhexdhexaadka ah iyo kuwa waaweyn, miisaanka iyo qiimaha saxanka hagaha iftiinka ayaa kordhi doona marka cabbirka la kordhiyo, dhalaalka iyo isku-midnimada qiiqa iftiinkana ma aha kuwo ku habboon. Guddiga iftiinka ma ogaan karo xakamaynta firfircoonida gobolka ee LCD TV-ga, laakiin wuxuu kaliya ogaan karaa hoos u dhac hal-cabbir ah oo fudud, halka iftiinka dambe ee LED-ka ee tooska u iftiimaya uu si ka wanaagsan u shaqeeyo oo uu xaqiijin karo xakamaynta firfircoonida gobolka ee LCD TV-ga. Habka iftiinka dambe ee tooska ah waa... -
Nalalka dambe ee LED-ka oo cidhif ku shidan
Iftiinka dambe ee LED-ka waxaa loola jeedaa isticmaalka LED-yada (diodes-yada iftiinka soo saara) sida isha iftiinka dambe ee bandhigga kiristaalka dareeraha ah, halka bandhigga dambe ee LED-ku uu yahay isha iftiinka dambe ee bandhigga kiristaalka dareeraha ah ee ka imanaya tuubada iftiinka qabow ee CCFL ee dhaqameed (oo la mid ah laambadaha iftiinka soo saara) ilaa LED (diode-ka iftiinka soo saara). Mabda'a sawir-qaadista kiristaalka dareeraha ah waxaa si fudud loo fahmi karaa xaqiiqda ah in danabka dibadda ee loo adeegsado in lagu leexiyo molecules-ka kiristaalka dareeraha ah uu xannibi doono hufnaanta... -
Nalalka yaryar
Tiknoolajiyadda Mini LED waa tiknoolaji cusub oo bandhig ah. Marka laga soo tago in lagu isticmaalo TV-yada, tiknoolajiyadda Mini LED waxay sidoo kale ka soo muuqan kartaa aaladaha casriga ah sida kiniiniyada, taleefannada gacanta, iyo saacadaha mustaqbalka. Sidaa darteed, tiknoolajiyaddan cusub waxay mudan tahay in la fiirsado. Tiknoolajiyadda Mini LED waxaa loo arki karaa nooc la casriyeeyay oo ka mid ah shaashadda LCD-ga dhaqameed, kaas oo si wax ku ool ah u hagaajin kara isbarbardhigga oo kor u qaadi kara waxqabadka sawirka. Si ka duwan shaashadaha OLED ee is-iftiimiya, tiknoolajiyadda Mini LED waxay u baahan tahay nalka dambe ee LED... -
baar iftiin ah
Iftiinka dambe ee LED-ka waxaa loola jeedaa isticmaalka LED (diode-ka iftiinka soo saara) oo ah isha iftiinka dambe ee shaashadaha LCD. Marka la barbardhigo isha iftiinka dambe ee CCFL (tuubada cathode-ka qabow), LED-ku wuxuu leeyahay astaamo ah isticmaalka awoodda oo hooseeya, qiimo kaloori hooseeya, dhalaal sare iyo cimri dheer, kaas oo la filayo inuu si buuxda u beddelo nidaamka iftiinka dambe ee dhaqameed sannadihii la soo dhaafay. Iftiinka iftiinka dambe ee LED-ku waa sarreeyaa, dhalaalka iftiinka dambe ee LED-kuna ma yaraan doono muddo dheer. Intaa waxaa dheer,...
