Grayscale Level Grayscale, colour level emaw gray scale emaw tia hriat bawk hian rawng eng eng emaw zat a kawk a ni. Digital display technology atan chuan grayscale hi rawng tarlan zat tur tichiangtu a ni. A tlangpuiin, grayscale a san poh leh a rawng tarlan te chu a hausa zawk a, thlalak chu a nalh zawk a, thil chipchiar tak tak sawi chhuah a awlsam zawk bawk. Grayscale level hi system-a A/D conversion-a bit awm zat a innghat ber a ni.
