Kweli nqaku, siza kugubungela yonke imiba ebalulekileyo yomahluko, kubandakanya inkcazo yayo, ifuthe layo ekusebenzeni komboniso, kunye neengcebiso zokuphucula.

Makhe sihlolisise izinto ezinegalelo kwabo bantsundu bazizityebi nabamhlophe abaqaqambileyo!

1. Ukuchaza iScreen Contrast Ratio

1.1 Yintoni iDisplay Contrast Ratio?

Umlinganiselo wokuthelekisa umele umahluko phakathi kowona umhlophe oqaqambileyo kunye nobumnyama obumnyama obunokuveliswa ngumboniso. Umlinganiselo ophezulu wokuchasana uthetha umahluko ocacileyo phakathi kokukhanya kunye nemimandla emnyama kwisikrini.

Oku kunokwandisa kakhulu ukucaca komfanekiso kunye neenkcukacha, okwenza kube lula ukubona iiyantlukwano ezifihlakeleyo kwimifanekiso okanye iividiyo.

Umzekelo, umboniso onomlinganiselo ophezulu wokuchasana unokuvelisa ubunzulu, abamnyama bokwenyani ecaleni kwabamhlophe abaqaqambileyo, okukhokelela kumfanekiso odlamkileyo kunye nofana nobomi. Ngokuchaseneyo, umlinganiselo osezantsi wokuchasana unokukhokelela kwimifanekiso ebonakala ihlanjiwe okanye ingachazwanga kancinci.

1.2 Imelwe njani i-Contrast Ratio?

Umlinganiselo wokuchasana kwesikrini udla ngokuboniswa njengomlinganiselo, njenge-1000:1 okanye 3000:1. Olu bhalo lubonisa ukuba mangaphi amaxesha amhlophe aqaqambileyo xa kuthelekiswa nomnyama omnyama.

Umzekelo, umlinganiselo we-1000: 1 uthetha ukuba olona mhlophe luqaqambileyo luphindwe ka-1000 ngakumbi kunobona mnyama bumnyama uveliswa sisiboniso. Umlinganiselo we-3000:1 ubonisa umahluko omkhulu ngakumbi, kunye nomhlophe ukugqama ngama-3000 ngokuphindwe kabini kunomnyama.

Umlinganiselo ophezulu wokuchasana ukhokelela kwimifanekiso ecacileyo kunye neenkcukacha. Nangona kunjalo, amava okubukela ehlabathi lokwenyani anokuxhomekeka kwezinye izinto, ezinje ngeteknoloji yesikrini kunye neemeko zokukhanya ezingqongileyo.
