Title: High gradation display technology
Inventor: TANAKA YUKIO
IPC: G09F9/30
Filed: 2000-08-24
Abstract: PROBLEM TO BE SOLVED: To obtain gradation display which has satisfactory gradation reproducibility and color reproducibility and which are stable with time and are hardly effected by temperature changes.

For example, a display cycle is equally divided into 8 pieces of sections and luminance of an optical source (batch optical modulation means) in a section (k) (0<=k<=7) is made to proportional to 1/2k. Then, in each section, either a voltage V such as that liquid crystal (two-dimensional optical modulation means) becomes off or a voltage such as that it becomes on is applied to liquid crystals. Thus, linear 256 gradation can be obtained digitally in accordance with 28=256 kinds of voltage applying methods by performing gradation in this manner.
