LCD apparatus with improved gray scale at large viewing angles and method and apparatus for driving same |
摘要 |
A liquid crystal display apparatus in normally-white mode in which gray scale display is obtained by providing different applied voltages corresponding to different gray scale levels, respectively, characterized in that in a curve showing the relationship between the applied voltage and light transmittance, the lowest applied voltage is set so as to be shifted in the direction of a monotonically decreasing region of the curve. The display simultaneously provides both good contrast ratios and good gradation at large viewing angles, and gray scale is not inverted.
