LCD (Liquid Crystal Display) ne LED (light-emitting diode) yɛ mfiri a wɔtaa de kyerɛ nneɛma a wɔde hwɛ screens wɔ nnuruyɛ mfiri mu, na nsonsonoe titiriw wɔ abien no ntam:
Backlight mfiridwuma:
LCD screens: Nsu ahwehwɛ a ɛda adi no ankasa mma hann na ɛhwehwɛ sɛ wonya akyi kanea. Amammerɛ LCD screens de cathode fluorescent kanea a ɛyɛ nwini (CCFL) di dwuma sɛ akyi kanea fibea.
LED screens: LED screens de diodes a ɛma hann di dwuma sɛ akyi kanea fibea, a ɛwɔ ahorow abien titiriw: tẽẽ-di anim ne ano-di anim.
hann ne nsonsonoe a ɛwɔ mu:
LCD screens: LED akyi kanea taa ma hann ne nsonsonoe a ɛkorɔn. Nanso, ebia CCFL mfiridwuma dedaw no wɔ anohyeto ahorow bi.
LED screens: Fa backlighting a ɛyɛ pɛ pii ma, na ɛboa ma mfonini no nyinaa tu mpɔn.
Ahoɔden a wɔde di dwuma yiye ne ne kɛse:
LCD screens: LED akyi kanea no taa yɛ nea ahoɔden ntumi nyɛ adwuma yiye, na LED module ahorow no yɛ mmerɛw, na ɛboa ma wɔyɛ aduruyɛ mu nhwehwɛmu screen a ɛyɛ tratraa no.
LED Screens: Ɛyɛ mmerɛw na ɛyɛ hare, na ɛma ɛfata kɛse ma dwumadie a ne kɛseɛ ne ne mu duru a ɛyɛ den.
Kɔla a ɛyɛ adwuma:
LCD screens: Ebetumi ama kɔla gyinabea a ɛyɛ pɛpɛɛpɛ, titiriw wɔ in-plane switching (IPS) panels ho.
LED screens: ebetumi nso anya kɔla a ɛkorɔn pɛpɛɛpɛ, nanso adwumayɛ pɔtee gyina LED akyi kanea mfiridwuma ne screen no su so.
Nkwa nna ne ahotoso:
LCD screens: Ebia LCD screens dedaw no wɔ nsɛm te sɛ kanea nkwa nna, nanso mfiridwuma foforo adi saa nsɛm yi ho dwuma.
LED Screens: Mpɛn pii no, ɛwɔ nkwa tenten na ɛyɛ nea wotumi de ho to so kɛse a ɛfa nneɛma te sɛ filament ho.
Wɔ nnuruyɛ mfiri ho nsɛm mu no, susuw nhwɛso ahorow te sɛ thermometers, mogya mmoroso a wɔde hwɛ nneɛma, ne nufu a wɔde bɔ mu ho. Saa mfiri yi taa de LCD anaa LED screens di dwuma ma user interfaces. Sɛ nhwɛso no, ebia dijitaal ɔhyew kyerɛwtohɔ de LCD screen bedi dwuma de akyerɛ ɔhyew a wɔasusuw no pɛpɛɛpɛ.
