Abstract:
A gray scale display device for displaying gray levels by combining plurality of sub-fields obtained by dividing one field period, comprising:a light intensity information converter circuit, responsive to a light intensity of said combined sub-fields, for outputting light intensity information,wherein said sub-fields include at least one set of 3 sub-fields having a first sub-field,a second sub-field adjacent to said first sub-field having a light intensity smaller than two times a light intensity of said first sub-field and larger than said light intensity of said first sub-field, anda third sub-field adjacent to said second sub-field having a light intensity smaller than two times said light intensity of said second sub-field and larger than said light intensity of said second sub-field,wherein a difference between said light intensity of said first sub-field and said light intensity of said second sub-field is substantially equal to a difference between said light intensity of said second sub-field and said light intensity of said third sub-field.
